The simplest form would be -3/4
Answer:
x = -4
Step-by-step explanation:
5(4x+9)=-50+15
20x+45=-50+15
20x+45=-35
-45 -45
20x=-80
/20 /20
x=-4
All quadrilaterals equal up to 360<span />
Setup 2 problems
2x - 7 < 15 and 2x - 7 > -15
2x < 22 2x > -8
x < 11 x > -4
Or you can write it -4 < x < 11
Answer:
Step-by-step explanation:
If the price is linear, then the slope between each pair of points must be the same.
m = Δy/Δx
m = (150 - 70) / (5 - 1) = 20
m = (450 - 150) / (20 - 5) = 20
m = (1050 - 450) / (50 - 20) = 20
So the equation is indeed linear. It has a slope of 20 and y-intercept of 50.
p = 20n + 50
