-Daniyal saved all he earned each month and put it into a savings account. The amount she had in her savings account is recorded below. What equation best represents this data?

y = 15x + 200

Step-by-step explanation:

It should be y = 150x + 200 because if you look at the first one, 300x is too big.

You can cross out the last two.

Then you can see the second one also doesn't work.

Cross that one out.

The first choice is the only one.

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.
