To re-phrase this: 50 is a certain percent of 90.
this can be written mathematically as 50=x%*90
let's divide both sides by 10:
5=x%*9
and divide both sides by 9:

which in decimals is approximately 0.56 (but not exactly).
so 0.56=x%
and the x then 56
so 50 is
approximately 56% of 90:
exactly 56%of 90 is 50.4
Answer:
y=-2x-5
Step-by-step explanation:
y-y1=m(x-x1)
y-(-7)=-2(x-1)
y+7=-2x+2
y=-2x+2-7
y=-2x-5
Answer:
C. (4,28)
Step-by-step explanation:
When y = 8x - 4 ; x = 4
when u substitute x in the equation
the value of y = 28
y = (8 x 4) - 4
= 32 - 4
= <u>2</u><u>8</u><u>.</u>
As coordinates it would be (x,y) = <u>( 4,28 )</u>
