Answer:
y = 5x + 3 (or, any line with the slope equal to 5 and a different y-intercept)
Step-by-step explanation:
Parallel lines will have the same slope.
So, a line such as y = 5x + 3 will be parallel because it has the same slope as the original line, which is 5.
There are almost an infinite amount of parallel lines, it just has to have the same slope and a different y-intercept.
Lines like y = 5x + 1 and y = 5x are also parallel.
Answer:
y=5x-8
Explanation:
A line that is parallel to another has the same slope.
The difference between these is where they cross the y-axis.
Hopefully this helps, have a good dayy!! :)
Graph the image of the given triangle after the transformation with the rule (x, y)→(x−1, y+2). Select the "Polygon" button from the tool bar to plot your triangle. You may use the "Move" button to move the triangle after it is created.
Answer:
Just took the test
Step-by-step explanation:
The triangle by transformation with the rule (x, y)→(x−1, y+2) gives a triangle with vertices (-3,0), (6,5), and (3,7) and has been graphed.
How to plot a graph?A graph is a diagram that shows the fluctuation of one variable in relation to one or more other variables.
In order to plot the graph, we need to find out y's values corresponding to x's value
After that, we need to substitute the values of x's and y's into the coordinate geometry.
The transformation of the given triangle by rule (x, y)→(x−1, y+2) will
result in an increment of all y's values by 2 and a decrement of x's by 1.
(-2,-2) → (-3,0)
(7,3) → (6,5)
(4.5) → (3,7)
Hence "The triangle by transformation with the rule (x, y)→(x−1, y+2) gives a triangle with vertices (-3,0), (6,5), and (3,7)".

Write the equation for a line in slope-intercept form (y=mx+b) that
is parallel to y = -2x + 3 and passes through the point (-3,5).
Answer:
y = -2x - 1
Step-by-step explanation:
Parallel lines have the same slope, so the slope will also be -2.
Plug this slope and the given point into the equation y = mx + b and solve for b:
y = mx + b
5 = -2(-3) + b
5 = 6 + b
-1 = b
Then, plug this and the slope into the equation:
y = -2x -1 will be the equation
Which parent functions have no symmetry?
Cubic
Quadratic
Greatest Integer
Square Root
Exponential
Rational
Linear
Absolute Value
Answer:
Square Root, Greatest Integer
Step-by-step explanation:
Functions can be symmetrical in two ways: They can be symmetrical across a line or symmetrical across a point.
In a Square root function, when reflected across the y-axis, the graph has no symmetry because -x returns a different value when plugged into the function.
For a Greatest Integer function, with [tex]\lfloor x \rfloor[/tex], if we change the value of x to -x and we floor -x, we get a different value than the original.

If angle ABC measures 35 degrees and angle BAC measures 115 degrees, what’s the angle measure of DCB?
Answer:
30 degrees
Step-by-step explanation:
Assuming you are talking about a triangle, you would add 35 and 115 to get 150. Then subtract from 180.
35+115=150
180-150=30
what is the value of m in −4(m−26)=−12m
Answer:
M = -13
Step-by-step explanation:
Divide both sides by -4−4.
m−26=3m
Subtract mm from both sides.
−26=3m−m
Simplify 3m - m to 2m.
−26=2m
Divide both sides by 2
− 26/2=m
Simplify 26/2 to 13
-13=m
Switch sides.
m=13
Answer:
-13
Step-by-step explanation:
1. First distribute
2. Then get m on one side by adding 4m to both sides
3. Combine the numbers with the variable m
4. You need to get m by itself so divide both sides of the equation by -16
5. You should get m=-13
1.-4(m-26)=-4m+104 4m+4m+104=-12m
2. 104=-12m-4m
3. 104=-16m
4. 104/-13=-16/-16m
5. -13=m

Benito embroiders and sells T-shirts. The graph shows his profit as a function of the number of shirts sold. After selling a certain number of shirts, Benito uses some earnings to buy more materials and then increases the price of the shirts. Which of the following is true? A coordinate plane with 12 distinct points plotted which are not connected. The points are 0 comma negative 20, 1 comma negative 10, 2 comma 0, 3 comma 10, 4 comma 20, 5 comma 30, 6 comma 40, 7 comma 50, 8 comma 25, 9 comma 40, 10 comma 55, and 11 comma 70. Group of answer choices The x-intercept represents the shirts he has to sell before making a profit. Benito increases the price after selling 50 shirts. The y-intercept represents the cost of one T-shirt. The domain of the function is {x | x is a real number greater than or equal to 0}.
Answer:
The correct option is;
The x-intercept represents the shirts he has to sell before making a profit
Step-by-step explanation:
The given data are;
(0, -20), (1, -10), (2, 0), (3, 10), (4, 20), (5, 30), (6, 40), (7, 50), (8, 25), (9, 40), (10, 55), (11, 70)
The data show a linear relationship because successive data point increases by the same amount of 10 for x between 0 and 7 and 15 for x between 8 and 11;
Therefore;
Slope, m of the first linear portion using points (2, 0), and, (4, 20) gives;
m = (20 - 0)/(4 - 2) = 10
The equation of the line is therefore;
y - 20 = 10·(x - 4)
y = 10·x - 40 + 20
y = 10·x - 20
The y-intercept (x = 0) is y = -20
The x-intercept (y = 0) is found as follows;
0 = 10·x - 20
20 = 10·x
10·x = 20
x = 20/10 = 2
Therefore, when x = 2 we have;
Profit = y = 10·x - 20 = 10×2 - 20 = 0
Which can be expressed as, he has to sell more than 2 shirts to make profit
Therefore, the correct option is that the x-intercept represents the shirts he has to sell before making a profit.

Answer:
[tex]\Huge \boxed{x=8}[/tex]
[tex]\rule[225]{225}{2}[/tex]
Step-by-step explanation:
E ———— F ———— G
EG = EF + FG
27 = (2x - 8) + (4x - 13)
Combining like terms.
27 = 6x - 21
Adding 21 to both sides.
48 = 6x
Dividing both sides by 6.
8 = x
[tex]\rule[225]{225}{2}[/tex]
The value of the variable x will be 1.
What is a line segment?A line segment in mathematics has two different points on it that define its boundaries. A line segment is sometimes referred to as a section of a path that joins two places.
If EF = 2x - 8, FG = 4x - 13, and EG = 27.
Point F lies on the line segment EG. Then we have
EG = EF + FG
27 = 2x - 8 + 4x - 13
27 = 6x - 21
6 = 6x
x = 1
Then the value of the variable x will be 1.

Plot point C(2,7). If M is the midpoint of CD , what are the coordinates of D?
Answer:
The coordinates of D is (-4,-9)
Step-by-step explanation:
Given
C = (2,7)
M=(-1,-1) ----- Missing part of question
Required
Determine the coordinates of D
Let the coordinates of D be (x₂,y₂)
We'll solve this question using mid point formula;
[tex]M(x,y) = (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]
Where
[tex]C(x_1,y_1) = (2,7)[/tex] and [tex]M(x,y) = (-1,-1)[/tex]
Put these values in the formula
[tex](-1,-1) = (\frac{2+x_2}{2},\frac{7+y_2}{2})[/tex]
By comparison;
[tex]-1 = \frac{2+x_2}{2}[/tex] and [tex]-1 = \frac{7+y_2}{2}[/tex]
[tex]-1 = \frac{2+x_2}{2}[/tex]
Multiply both sides by 2
[tex]-2 = 2 + x_2[/tex]
Subtract 2 from both sides
[tex]-2 -2 = x_2[/tex]
[tex]x_2 = -4[/tex]
[tex]-1 = \frac{7+y_2}{2}[/tex]
Multiply both sides by 2
[tex]-2 = 7 + y_2[/tex]
Subtract 7 from both sides
[tex]-2 - 7 = y_2[/tex]
[tex]y_2 = -9[/tex]
Hence, the coordinates of D is (-4,-9)
Cooper will deposit $1,500 into an account that earns 7% simple interest every year. His sister Trinity will deposit $1,800 into an account that earns 6% simple interest every year. The deposits will be made on the same day, and no additional money will be deposited or withdrawn from the accounts. Which statement about the balances of Cooper's and Trinity's account at the end of 3 years is true?
Answer:
For Cooper :
Simple interest = $315
The total amount he would have in his account = $1815
For Trinity :
Simple interest = $324
The total amount she would have in her account = $2124
Trinity's interest is higher than Cooper's interest by $9
The total amount of money Trinity would have at the end of 3 years is higher than that of Cooper by $309
Step-by-step explanation:
Simple interest = principal x rate x time
Value = amount deposited + simple interest
For Cooper :
Simple interest = $1,500 x 0.07 x 3 = $315
The total amount he would have in his account = $1,500 + $315 = $1815
For Trinity :
Simple interest = $1800 x 0.06 x 3 = $324
The total amount she would have in her account = $1,800 + $324 = $2124

If the 11th term of a geometric sequence is 32 times larger than the 6th term, then what is the common ratio of the sequence?
Answer:
2
Step-by-step explanation:
Given that:
11th term of a geometric sequence is 32 times larger than the 6th term
The nth term of a geometric sequence is given by:
An = A*r^(n-1)
Where An = the nth term ; r = common ratio and n = term number ; A = first term
The 11th term:
A6 = A*r^(6 - 1) = Ar^5
A11 = 32A6 = 32Ar^5
A11 = Ar^(11 - 1) = Ar^10
Hence,
Ar^10 = 32Ar^5
r^(10 - 5) = 32
r^5 = 2^5
Hence, r = 2
