Could someone help me answer this question

Step-by-step explanation: A direct variation suggest that the value of x in the equation would greatly affect the value of y such that when x is increasing, y also increases and the other way around. The equation for a direct variation is that,

                                   y  = kx

Substituting the given values in the ordered pair,

                         5 = k(4)   ; k = 5/4

answer: 75°

step-by-step explanation:

∠esk is the supplement of ∠edk, so is 100°. ∠esd = 1/2·arc ed, so is 25°.

since ∠esk = ∠esd + ∠dsk

you have 100° = 25° + ∠dsk . .

fill in known values 75° = ∠dsk . . . . .

subtract 25°

step-by-step explanation:

if you are factoring then 4(x+3)

if you are simplifying 4x+12
