Y = -4x + 5
4x + y = 10

write in slope-intercept form, y=mx+b.y=−4x+10

x = 5

Step-by-step explanation:

y = -4x + 5 4x + y = 10

substitute the y in the second equation with

(-4x +5).

4x + (-4x + 5) = 10 then add like terms.

x + 5 = 10 solve for x.

10 - 5 = 5 make sure to check your answer.

5 + 5 = 10

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.

step-by-step explanation:

60°

step-by-step explanation:

the measure angle of c in an isosceles triangle abc is 60° because in isosceles triangle,the measures of all the angles is 60°.
