Answer:
C. It divides the radius by 4.
Step-by-step explanation:
We have x2 + y2 = 25.
If all terms were multiplied by 4, we would have 4x2 + 4y2 = 100. But, the radius is 25 units. 100 / 25 = 4. So, the radius was divided by 4.

Graph the solution of 7x+3<−4 or 2x−3≥9
Answer:
Step-by-step explanation:
To do this you would simplify both sides.
For the first one:
[tex]7x+3<-4[/tex]
[tex]7x<-7[/tex] (subtract 3 from both sides)
[tex]x<-1[/tex] (divide 7 from both sides)
and for the second one:
[tex]2x-3\geq 9[/tex]
[tex]2x\geq 12[/tex] (add 3 to both sides)
[tex]x\geq 6[/tex] (divide 2 from both sides)
When you graph these they will look like these pictures
Answer:
[tex]x<-1[/tex] and [tex]x\geq6[/tex]
Step-by-step explanation:
[tex]\bf 7x+3<-4[/tex]
You must subtract 3 from both sides.
[tex]7x+3-3<-4-3\\[/tex]
After subtracting, we got
[tex]7x<-7[/tex]
Let's make it into a fraction and divide
[tex]\frac{7x}{7}<\frac{-7}{7}[/tex]
Now we got the answer
[tex]x<-1[/tex]
[tex]\bf 2x-3\geq 9[/tex]
You must add 3 to both sides.
[tex]2x-3+3\geq 9+3[/tex]
After adding, we got
[tex]2x\geq 12[/tex]
Let's make it into a fraction and divide
[tex]\frac{2x}{2} \geq \frac{12}{2}[/tex]
Now we got the answer
[tex]x\geq 6[/tex]
Your answer is [tex]\bf x<-1[/tex] or [tex]\bf x\geq 6[/tex].
The following data points represent the number of points scored last basketball game by each player on the Dragons basketball team.
5,8,11,7,?
If the mean of the data set is 8 points, find the missing number of points.
Answer:
9
Step-by-step explanation:
There are 5 data points. To find the mean, we add the data and divide by 5
(5+8+11+7+?) /5 = 8
Multiply each side by 5
(5+8+11+7+?) /5 *5 = 8*5
(5+8+11+7+?) = 40
Combine like terms
? + 31 = 40
Subtract 31 from each side
? +31-31 = 40-31
? = 9
The missing number is 9

Answer:
h(3)=20
Step-by-step explanation:
h(3)=h(3-2)*h(3-1)=h(1)*h(2)=-10*-2=20
Answer:
20
Step-by-step explanation:
h(1) = -10
h(2) = -2
h(n) = h(n-2) * h(n-1)
Let n=3
h(3) = h(3-2) * h(3-1)

Solve each of the following equations
1-|3p+1|=-3
Answer:
p=1 p = -5/3
Step-by-step explanation:
1-|3p+1|=-3
Subtract 1 from each side
1-|3p+1| -1=-3-1
-|3p+1|=-4
Divide by -1
|3p+1|=4
The absolute value has two solutions one positive and one negative
3p+1 = 4 3p+1 = -4
Subtract 1 from each side
3p+1-1 = 4-1 3p+1-1 = -4-1
3p = 3 3p = -5
Divide by 3
3p/3 = 3/3 3p/3 = -5/3
p=1 p = -5/3
Answer:
p=-5/3,1
Step-by-step explanation:
Subtract 11 from both sides.
-|3p+1|=-3-1
−∣3p+1∣=−3−1
2 Simplify -3-1−3−1 to -4−4.
-|3p+1|=-4
−∣3p+1∣=−4
3 Multiply both sides by -1−1.
|3p+1|=4
∣3p+1∣=4
4 Break down the problem into these 2 equations.
3p+1=4

PLease answer !!! Find constants $A$ and $B$ such that \[\frac{x + 7}{x^2 - x - 2} = \frac{A}{x - 2} + \frac{B}{x + 1}\] for all $x$ such that $x\neq -1$ and $x\neq 2$. Give your answer as the ordered pair $(A,B)$. and Find all values of $t$ such that $\lfloor t\rfloor = 2t + 3$. If you find more than one value, then list the values you find in increasing order, separated by commas.
Answer:
1. [tex](A,B) = (3,-2)[/tex]
2. The values of t are: -3, -1
Step-by-step explanation:
Given
[tex]\frac{x + 7}{x^2 - x - 2} = \frac{A}{x - 2} + \frac{B}{x + 1}[/tex]
[tex]|t| = 2t + 3[/tex]
Required
Solve for the unknown
Solving [tex]\frac{x + 7}{x^2 - x - 2} = \frac{A}{x - 2} + \frac{B}{x + 1}[/tex]
Take LCM
[tex]\frac{x + 7}{x^2 - x - 2} = \frac{A(x+1) + B(x-2)}{(x - 2)(x-1)}[/tex]
Expand the denominator
[tex]\frac{x + 7}{x^2 - x - 2} = \frac{A(x+1) + B(x-2)}{x^2 - 2x + x -2}[/tex]
[tex]\frac{x + 7}{x^2 - x - 2} = \frac{A(x+1) + B(x-2)}{x^2 - x -2}[/tex]
Both denominators are equal; So, they can cancel out
[tex]x + 7 = A(x+1) + B(x-2)[/tex]
Expand the expression on the right hand side
[tex]x + 7 = Ax + A + Bx - 2B[/tex]
Collect and Group Like Terms
[tex]x + 7 = (Ax + Bx) + (A - 2B)[/tex]
[tex]x + 7 = (A + B)x + (A - 2B)[/tex]
By Direct comparison of the left hand side with the right hand side
[tex](A + B)x = x[/tex]
[tex]A - 2B = 7[/tex]
Divide both sides by x in [tex](A + B)x = x[/tex]
[tex]A + B = 1[/tex]
Make A the subject of formula
[tex]A = 1 - B[/tex]
Substitute 1 - B for A in [tex]A - 2B = 7[/tex]
[tex]1 - B - 2B = 7[/tex]
[tex]1 - 3B = 7[/tex]
Subtract 1 from both sides
[tex]1 - 1 - 3B = 7 - 1[/tex]
[tex]-3B = 6[/tex]
Divide both sides by -3
[tex]B = -2[/tex]
Substitute -2 for B in [tex]A = 1 - B[/tex]
[tex]A = 1 - (-2)[/tex]
[tex]A = 1 + 2[/tex]
[tex]A = 3[/tex]
Hence;
[tex](A,B) = (3,-2)[/tex]
Solving [tex]|t| = 2t + 3[/tex]
Because we're dealing with an absolute function; the possible expressions that can be derived from the above expression are;
[tex]t = 2t + 3[/tex] and [tex]-t = 2t + 3[/tex]
Solving [tex]t = 2t + 3[/tex]
Make t the subject of formula
[tex]t - 2t = 3[/tex]
[tex]-t = 3[/tex]
Multiply both sides by -1
[tex]t = -3[/tex]
Solving [tex]-t = 2t + 3[/tex]
Make t the subject of formula
[tex]-t - 2t = 3[/tex]
[tex]-3t = 3[/tex]
Divide both sides by -3
[tex]t = -1[/tex]
Hence, the values of t are: -3, -1

Find the measure of the remote exterior angle. m∠x=(197−5n)°m∠y=(6n+22)°m∠z=(n+7)°
A. 14
B. 91
C. 21
D. 127
Answer:
D. 127°
Step-by-step explanation:
The exterior angle (x) is the sum of the remote interior angles (y, z).
Setupx = y +z
(197 -5n) = (6n +22) +(n +7) . . . . . substituting the given expressions
SolutionEliminating parentheses and collecting terms, we have ...
197 -5n = 7n +29
168 = 12n . . . . . . . . . add 5n-29
14 = n . . . . . . . . . . divide by 12
Then the measure of remote exterior angle x is ...
m∠x = (197 -5(14))° = (197 -70)°
m∠x = 127°

Which scatterplot shows the strongest negative linear association? On a graph, points are grouped closely together and increase. On a graph, points are grouped closely together to form a line and increase. On a graph, points are grouped closely together and decrease. On a graph, points are grouped closely together to form a line and decrease.
On a graph, points are grouped closely together to form a line and decrease.
====================================
Explanation:
Negative association is where the points decrease as you move from left to right. In other words, you move downhill as you move from left to right. There could be random upward bumps here and there, but overall the general trend is down.
Linear association is when the points are close to the same straight line, known as the regression line.
When points have strong negative linear association, we combine the two ideas mentioned above. The points are close to the same straight line and this line has a negative slope. The correlation coefficient r is close to r = -1.
Choice C is a close answer, but choice D is the better answer due to the "to form a line". If all points are on the same straight line, then r = -1 exactly and we have the strongest possible negative correlation.
The strongest negative linear association is depicted by the graph where points are grouped closely together to form a line and decrease.
Linear associations are deduced from a graph when the points are grouped closely together to form a line. Then we have a strong linear association. Negative association are deduced from a graph when the slope of the line decreasesTherefore, a graph with closely grouped points which forms a line and decreases infers a strong negative linear association.

There are four points on a line: A, B, C and D, so that AB=1, BC=2, CD=4. Find all the possibilities of the length of segment AD.
Answer:
{1, 3, 5, 7}
Step-by-step explanation:
There are four possibilities:
AD = AB -BC -CD = 1 -2 -4 = -5
AD = AB +BC -CD = 1 +2 -4 = -1
AD = AB -BC +CD = 1 -2 +4 = 3
AD = AB +BC +CD = 1 +2 +4 = 7
Possible lengths of AD are 1, 3, 5, 7.
__
The negative sign means the segment is added toward the left instead of toward the right. A final negative value means D is left of A, instead of to the right.

Find the output, h, when the input, x, is -18.
h = 17 + x/6
Answer:
14
Step-by-step explanation:
The expression is h = 17 + x/6
Replace x by -18
● h = 17 + x/6
● h = 17 + (-18/6)
● h = 17 +(-3)
● h = 17 -3
● h = 14
So the output when x = -18 is 14
h=14
h=17+18/6
h=17+-3
h=17-3

If g (x) is the inverse of f (x) and f (x) = 4 x + 12, what is g (x)
g (x) = 12 x + 4
g (x) = one-fourth x minus 12
g (x) = x minus 3
g (x) = one-fourth x minus
Answer:
[tex]g(x) = \frac{1}{4} x - 3[/tex]Step-by-step explanation:
Since g(x) is the inverse of f (x) to find g(x) must first find f-¹(x)
To find f-¹(x) equate f(x) to y
That's
f(x) = y
y = 4x + 12
Next interchange the terms x becomes y and y becomes x
That's
x = 4y + 12
Next make y the subject
4y = x - 12
Divide both sides by 4
[tex]y = \frac{1}{4} x - 3[/tex]Therefore
[tex]g(x) = \frac{1}{4} x - 3[/tex]Hope this helps you
The coefficient of 8.2 N is
8
2
16
Answer:
2
Step-by-step explanation:
A coefficient is the number placed before the variable. The variable gets multiplied by the coefficient.
The format is not exactly clear with the expression in the question.
Assuming the expression is '8 * 2n', the coefficient would be 2.
'n' is getting multiplied by '2'.
'8' does not have a variable next to it, so it is just a term in the expression.
The product of 8 and 2 is 16. 16 is not in the expression.
If the expression was '8.2n', 8.2 would be the coefficient.
