Answer:

$y = 2$

Step-by-step explanation:

Given

$5 + y = 7$

Required

Solve

From the analysis attached to the question, we can solve this equation by subtracting 5 from both sides:

$5 + y = 7$

$-5 + 5 + y = 7 - 5$

$0 + y = 2$

$y = 2$

The measure of AngleRST can be represented by the expression (6x + 12)°. Three lines extend from point S. The space between line

DochEvi [55]

Answer:The measure of angle RST is 120\°

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

m<RST=(6x+12)\° -----> equation A

m<RST=78\°+(3x-12)\° -----> equation B

equate equation A and equation B

(6x+12)\°=78\°+(3x-12)\°

For each function, y varies directly with x. Find each constant of variation. Then find the value of y when x=-0.3

Viktor [21]

Answer:

1- The constant of variation is $\frac{10}{3}$

2- The constant of variation is $\frac{4}{3}$

Explanation:

When two variables are in direct variation, this means that when one of them increases, the other increases and vice versa

A direct variation relation is represented as follows:

y = kx

where k is the constant of variation

Now, to get the constant of variation, all we have to do is substitute with the given x and y variables and solve for k

For the given problems:

1- $y = \frac{2}{3}\ when\ x=0.2$ 

Therefore:

$y = kx\\\\\frac{2}{3} = 0.2k\\\\ k = \frac{10}{3}$

2- $y = 4\ when\ x=3$ 

Therefore:

$y = kx\\ 4 = 3k\\ k = \frac{4}{3}$

Hope this helps :)

Explain how you can find the y-intercept of a linear equation and how that is different from finding the y-intercept of a geomet

Gnesinka [82]

The Y-Intercept of a line is the point where a line's graph intersects (crosses) the Y-axis. A y-intercept of 3 means that a line's graph intersects the Y-axis at the point (0,3). A y-intercept of -4 means that the graph of a line crosses the Y-axis at the point (0,-4).
