Solve for x
3x=4y-10
x=(4y-10)/3
solver for y
3x=4y-10
rewrite as 4y-10=3x
4y-10+10=3x+10
4y=3x+10
y=(3x+10)/4
Answer: (f·g)(x) = -5x³ - 31x² + 62x + 18
(f·g)(1) = 44
<u>Step-by-step explanation:</u>
f(x) = x² + 8x + 2 g(x) = -5x + 9
(f·g)(x) = (x² + 8x + 2)(-5x + 9)
= -5x³ + 9x²
- 40x² + 72x
<u> - 10x + 18</u>
= -5x³ - 31x² + 62x + 18
(f·g)(1)= -5(1)³ - 31(1)² + 62(1) + 18
= -5 - 31 + 62 + 18
= 44
Answer:
C. (5, -3)
Step-by-step explanation:
Ordered pair just means the coordinate or the point at which both of the graphs intersect. On the x-axis, this is at point 5, and on the y-axis, this is at point -3. Since an ordered pair is in the form (x, y), the answer is therefore C.
Answer:
9
Step-by-step explanation:
multiply both sides by 15 to get:
45/5 = x
9 = x
Answer:
16
Step-by-step explanation:
5+3+2.50x=50
8+2.50x=50
-8 on both sides
2.50x=42
divide both sides by 2.50
x=16.8
