Everyone is saying it's C fam so it must be C.

C.No, it is not a dilation because the points of the image are not moved away from the center of dilation proportionally.

The total number of students in the seventh grade is 9 more than 4 times as many students as are in the art class. There are 101

7nadin3 [17]

Answer:

9 + 4x = 101

Step-by-step explanation:

9 + 4x = 101 Equation

( +9 - 9 ) + 4x = ( 101 - 9 ) Subract 9 on both sides

4x = 92 Simplify

x = 23 Divide 4 on both sides

MrRissso [65]

Answer: 2, 6

Step-by-step explanation:

Triangle Inequality Theorem states that the sum of two sides must be GREATER than the third side.

RS + ST > RT and RS + RT > ST and ST + RT > RS

2x + 4x > 12 2x + 12 > 4x 4x + 12 > 2x

6x > 12 12 > 2x 12 > -2x

x > 2 6 > x -6 < x

2 < x x < 6 invalid

Answer: 2 < x < 6

Graph: O----------------------O

2 6

Note: -6 is invalid because you cannot have a negative length.

Consider this system of equations. Which shows the second equation written in slope-intercept form? y = 3 x minus 2. 10 (x + thr

Arte-miy333 [17]

Question

Consider this system of equations. Which shows the second equation written in slope-intercept form?

$y = 3x - 2.$

$10(x + \frac{3}{5} ) = 2y$

A. $y = 5x + \frac{3}{10}$

B. $y = 5x + 3$

C. $y = \frac{1}{5} x + \frac{3}{25}$

D. $y = \frac{1}{2} x + 6$

Answer:

B. $y = 5x + 3$

Step-by-step explanation:

Given

Equation 1: $y = 3x - 2.$

Equation 2: $10(x + \frac{3}{5} ) = 2y$

Required:

Equivalent of equation 2

To get an equivalent of equation 2 (in slope intercept form), first we have to simplify equation 2

$10(x + \frac{3}{5} ) = 2y$

Open the bracket

$10*x + 10 *\frac{3}{5} = 2y$

$10x + \frac{30}{5} = 2y$

Simplify fraction

$10x + 6 = 2y$

Divide through by 2

$\frac{10x}{2} + \frac{6}{2} = \frac{2y}{2}$

$5x + 3 = y$

Re-arrange

$y = 5x + 3$

The next step is to compare each of option A through D with $y = 5x + 3$

$y = 5x + \frac{3}{10}$ is not equal to $y = 5x + 3$

We check the next available option

$y = 5x + 3$ is equal to $y = 5x + 3$

This option is equivalent to the second equation in slope-intercept form.

We check further if there are more equivalent options

$y = \frac{1}{5} x + \frac{3}{25}$

Convert fraction to decimal

$y = 0.2x + 0.12$

This is not equal to $y = 5x + 3$

$y = \frac{1}{2} x + 6$

Convert fraction to decimal

$y = 0.5x + 6$

This is not equal to $y = 5x + 3$

Hence, the only equation that is equivalent to the second equation written in slope intercept form is Option B
