What combination of transformations is shown below?
A) translation, then rotation
B) translation, then reflection
C) rotation, then reflection
D) rotation, then translation
Explanation:
Going from figure (1) to figure (2) has us rotate 90 degrees counterclockwise. Note the smallest side of the green figure how it is horizontal, and it corresponds to the smallest side of the blue figure and it is vertical. The center of rotation is the top right corner of the green figure.
Then we apply a translation to go from figure (2) to figure (3). This is another way of saying we shifted the figure some distance left/right and up/down. In this case, we shifted 1 unit to the right and 4 units down.

Which statement is true? Group of answer choices 8.01 is a smaller increase in sales then 8.001. A debt of $17 is a larger value than a debt of $20. LaTeX: \frac{2}{3} 2 3 below zero is a lower temperature than 6 below zero. One half an apple is equivalent to 8 fourths apples.
Answer: The only true statement is:
" A debt of $17 is a larger value than a debt of $20."
Step-by-step explanation:
Let's analyze the options:
A) " 8.01 is a smaller increase in sales then 8.001"
Here you can see the difference:
8.01 - 8.001 = 0.009
The difference is positive, then 8.01 > 8.001.
Then as we are talking of increases in sales, the numbers are positive, then we have that 8.01 is a larger increase in sales than 8.001.
B) "A debt of $17 is a larger value than a debt of $20."
A debt is written as a negative number, then:
A debt of $17 is written as -$17, and a debt of $20 is written as -$20.
Then -$17 is a smaller negative number than -$20
-$17 > -$20
Then this statement is true.
C) " 2/3 bellow zero is lower than 6 bellow zero"
ok, 2/3 bellow zero is: -2/3
6 bellow zero is: -6
-2/3 is larger than -6
-2/3 > -6
then -6 is lower than -2/3, the statement is false.
D) "1/2 of an apple is equivalent to 8/4 apples"
Well, here you can do the quotients:
1/2 = 0.5
8/4 = 2
So these numbers are not equivalents.

For the following system, if you isolated x in the first equation to use the substitution method, what expression would you substitute into the second equation? −x + 2y = −6 3x + y = 8
Answer:
[tex]x=2y+6[/tex]
Step-by-step explanation:
So we have the system:
[tex]-x+2y=-6\\3x+y=8[/tex]
If we isolate the x-variable in the first equation:
[tex]-x+2y=-6[/tex]
Subtract 2y from both sides:
[tex]-x=-6-2y[/tex]
Divide both sides by -1:
[tex]x=2y+6[/tex]
Therefore, we would substitute the above into the second equation:
[tex]3x+y=8\\3(2y+6)+y=8[/tex]
The answer is 2y+6
Further notes:
To solve for the system, distribute:
[tex]6y+18+y=8[/tex]
Simplify:
[tex]7y+18=8[/tex]
Subtract:
[tex]7y=-10[/tex]
Divide:
[tex]y=-10/7\approx-1.4286[/tex]
Now, substitute this value back into the isolated equation:
[tex]x=2(-10/7)+6\\x=-20/7+42/7\\x=22/7\approx3.1429[/tex]
Step-by-step explanation:
Start by solving the equation for x (☓)
[tex] - x + 2y = 6 \\ \: \: \: \: \: 3 + y = 8[/tex]
[tex]x = 6 + 2y[/tex]
Substitute the given value of x for the equation 3 + y = 8[tex]3(6 + 2y) + y = 8[/tex]
solve the equation for y[tex]y = - \frac{10}{7} [/tex]
substitute the given value of y into the equation x = 6 + 2[tex]x = 6 + 2 \times ( - \frac{10}{7} )[/tex]
solve the equation for x[tex]x = \frac{22}{7} [/tex]
The possible solution of the system is the ordered pair (x,y)[tex] (\frac{22}{7} . - \frac{10}{7} )[/tex]
The dot (.) in the center is supposed to be a comma but the scientific keyboard does not support a comma[tex](x.y) \: \: ( \frac{22}{7} . - \frac{10}{7} )[/tex]
This is the solution Marnie out!Hudson bought a plant and planted it in a pot near a window in his house. The initial height of the plant was 8 inches and it grew at a rate of 3 inches per month. Write an equation for H,H, in terms of t,t, representing the height, in inches, of the plant tt months after Hudson bought the plant.
Answer:
H = 3t + 8
Step-by-step explanation:
Since the plant has an initial height of 8 inches, this will be added to the amount it grows each month.
3t will represent how much it grows t months after he bought the plant, since it grows 3 inches each month.
So, the equation will be H = 3t + 8

The null hypothesis says that a sprinter's reaction time follows a normal distribution with mean at most 0.150 seconds. Six measurements of a sprinter's reaction time show 0.152, 0.154, 0.166, 0.147, 0.161, and 0.159 seconds. What is the p value
Answer:
The P-value is 0.0353.
Step-by-step explanation:
We are given the six measurements of a sprinter's reaction time show below;
X = 0.152, 0.154, 0.166, 0.147, 0.161, and 0.159 seconds.
Let [tex]\mu[/tex] = mean sprinter's reaction time
So, Null Hypothesis, [tex]H_0[/tex] : [tex]\mu \leq[/tex] 0.150 seconds {means that the mean sprinter's reaction time is at most 0.150 seconds}
Alternate Hypothesis, [tex]H_A[/tex] : [tex]\mu[/tex] > 0.150 seconds {means that the mean sprinter's reaction time is more than 0.150 seconds}
The test statistics that will be used here is One-sample t-test statistics because we don't know about the population standard deviation;
T.S. = ~
where, [tex]\bar X[/tex] = sample mean = [tex]\frac{\sum X}{n}[/tex] = [tex]\frac{0.939}{6}[/tex] = 0.1565 seconds
s = sample standard deviation = [tex]\sqrt{\frac{\sum (X-\bar X)^{2} }{n-1} }[/tex] = 0.0068 seconds
n = sample of measurements = 6
So, the test statistics = [tex]\frac{0.1565-0.150}{\frac{0.0068}{\sqrt{6} } }[/tex] ~ [tex]t_5[/tex]
= 2.341
The value of t-test statistics is 2.341.
Now, the P-value of the test statistics is given by the following formula;
P-value = P( > 2.341) = 0.0353.

find 5 rational numbers between 1/3 & 2/5
Answer:
41/120, 7/20, 43/120, 11/30, 3/8
Step-by-step explanation:
Write the numbers.
1/3 & 2/5
We need a common denominator, but not the least common denominator. Both 3 and 5 are factors of 60, so let's use 60 as the common denominator.
Multiply 1/3 by 20/20:
1/3 = 20/60
Multiply 2/5 by 12/12:
2/5 = 24/60
Let's multiply each fraction again, but this time by 2/2.
1/3 = 40/120
2/5 = 48/120
Now it's easy to find 5 numbers between 40 and 48, so we get:
41/120, 42/120, 43/120, 44/120, 45/120
Some of these fractions can be reduced, so our answer is:
41/120, 7/20, 43/120, 11/30, 3/8

Find the coordinates of the other endpoint of the segment, given its midpoint and one endpoint. (Hint: Let (x,y) be the unknown endpoint. Apply the midpoint formula, and solve the two equations for x and y.) midpoint (-4,13) endpoint-(0,5)
Answer:
end point of a segment X₂ = - 8 ; Y₂ = 21
Step-by-step explanation:
given;
midpoint = ( Mx = -4 , My = 13 )
endpoint ₁ = ( X₁ = 0 , Y₁ = 5 )
find the other endpoint ₂ ( X₂ , Y₂)
use the mid point formula to get the other endpoint:
Mx = ( X₁ + X₂ ) / 2 My = ( Y₁ + Y₂ ) / 2
- 4 = (0 + X₂) / 2 13 = (5 + Y₂) / 2
-8 = 0 + X₂ 26 = 5 + Y₂
X₂ = -8 Y₂ = 21

graph the following lines y=2/3 x +4
Answer:
See attached graph.
Step-by-step explanation:
This equation is already in slope-intercept form.
This means the term next to the x is the slope, and the constant being added is the y-intercept.
We know that the y-intercept will be 4 because that’s the constant being added. We also know the slope is [tex]\frac{2}{3}[/tex].
A slope of [tex]\frac{2}{3}[/tex] will increase in x by 3, for every increase in y by 2.
This info can help us make the graph.

Juana tiene en su tienda un costal con 28 libras de azucar.Hizo seis paquetes de 2,5 kg cada uno, de los cuales vendio cinco.¿Cuanta azucar quedo en el costal?
Answer:
Quedan 3 libras de azúcar en el costal.
Step-by-step explanation:
Una kilo es aproximadamente dos libras y dos libras y media equivalen a un paquete, para determinar la cantidad remanente de libras de azúcar luego de las ventas se calcula la masa vendida por regla de tres compuesta:
[tex]x = 5\,p \times \frac{2,5\,kg}{1\,p}\times \frac{2\,lb}{1\,kg}[/tex]
[tex]x = 25\,lb[/tex]
Juana vendió 25 libras de azúcar. Entonces, la masa remanente de azúcar en el costal es:
[tex]x = 28\,lb-25\,lb[/tex]
[tex]x = 3\,lb[/tex]
Quedan 3 libras de azúcar en el costal.
The total amount of sugar left in the sack is 3 pounds.
Using the conversion:
1 kg = 2lb
2.5kg =5lb
If she sold 5 pounds out of the total package, the amount of pounds sold will be 5 * 5lb = 25lb.Amount of sugar left in the sack = Total - amount sold
Amount of sugar left in the sack = 28lb - 25lb
Amount of sugar left in the sack = 3lb
