bagirrra123 [75]

6 + 2(x - 5) = -40 - 5(x - 3)
6 + 2x - 10 = -40 - 5x + 15
-4 + 2x = -25 - 5x
2x = -21 - 5x
7x = -21
x = -3

If y is directly proportional to x and y = 17.5 when x=21 find y when x=39

morpeh [17]

direct proportion y=kx , k is constant and k does not equal to 0.

17.5=k(21)

k=5/6

when x =39

y=5/6 ×39

y=32.5

Answer:

The horizontal line is the x-axis and the vertical line is the y-axis.

Step-by-step explanation:

The horizontal line is the x-axis and the vertical line is the y-axis. It's a fact. You can graph the lines by inserting the equations using the graphing calculator, which is the tab next to the one you have right now ;)

RSTU is a parallelogram. If m∠SRV = 48° and m∠SVR = 54°, explain how you can find the measure of ∠TUV. Show all steps of your wo

const2013 [10]

Opposite angles in a parallelogram have equal measure.

The measure of angle TUV is 78 degrees

The given parameters are:

$\mathbf{\angle SRV = 48}$

$\mathbf{\angle SVR = 54}$

Start by calculating angle RSV.

$\mathbf{\angle RSV + \angle SVR + \angle SRV = 180}$ --- angles in a triangle

So, we have:

$\mathbf{\angle RSV + 54 + 48= 180}$

$\mathbf{\angle RSV + 102= 180}$

Subtract 102 from both sides

$\mathbf{\angle RSV = 78}$

Angles RSV and TUV are corresponding angles.

So, we have:

$\mathbf{\angle TUV = \angle RSV = 78}$

Rewrite as:

$\mathbf{\angle TUV = 78}$

Hence, the measure of angle TUV is 78 degrees
