Answer:
1 Rearrange the equation so "y" is on the left and everything else on the right.
2 Plot the "y=" line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>)
3 Shade above the line for a "greater than" (y> or y≥) or below the line for a "less than" (y< or y≤).
Step-by-step explanation:
Hello :
<span>If f(x)=x/2-2 and g(x)=2x^2+x-3, find (f+g)(x)
</span>(f+g)(x)= f(x) +g(x) = x/2-2 +2x²+x-3 = x/2 +2x²+x-5
(f+g)(x)= (x+4x²-2x-10) /2
(f+g)(x)= (4x²+3x-10)/2 = 2x²+3/2 x -5
Answer:
y=3x+5
Step-by-step explanation:
for slope rise over run and the y intercept is where the line hits the y axis
I think the answer is in Slader ( aka a app) it usually has answers to go math
