Answer:
x = -6
Step-by-step explanation:
-2x - 9 = 3
solve for x by inverse operations
-2x - 9 = 3
+9 +9
-2x = 12
/-2 /-2
x = -6
Point slope form is
Y-y1=m(x-x1)
-in this^ u only should put number in the y1, m, and x1
-m is your slope
Slope intercept form is
Y=mx+b
-start out with putting numbers in m and b and then you'll find your way to your y and x
475 - 95 = 380 = 20% of sales
20% = 1/5
380 × 5 = $1900 (the answer)
Hope this helps!
Answer:
f(-2) = -1
Step-by-step explanation:
One way of doing this is to substitute -2 for x in every place where x shows up:
f(x) = 4x + 3x^2 − 5 → f(-2) = 4(-2) + 3(-2)^2 − 5
→ f(-2) = -8 + 3(4) - 5, or f(-2) = 4 - 5, or f(-2) = -1
