Answer: 7. g = -50, 8. f= 340/6 9. 3 10 .125

Step-by-step explanation:#7 g(3): 4(3)^2 +6 =12^2 +6 = 1444=6= 150. We divide 150 by 3 giving us -50.  #8We start by putting f(6): -3(6)^2 -4(6) +8. We use PEMDAS. -18^2 -24 +8 = _324-24+8 F= 340/6 #9 g(15) = Square root of 15-6=9 and the square root of 9 is 3, therefore, the answer is 3. #10 h (x) = 2^x we plug -3 to 2^-3. It is a negative number and it gives us .125 or 12.5

  • Answer:

<em />

<em>7. g(3) = 42</em>

<em>8. f(6) = - 124</em>

<em>9. g(15) = 3</em>

<em>10. h(-3) = 1/8</em>

  • Step-by-step explanation:

<em></em>

<em>7.</em><em> g(x) = 4x² + 6</em>

<em>g(3) = 4×3² + 6</em>

<em>= 4×9 + 6</em>

<em>= 36 + 6</em>

<em>= 42</em>

<em />

<em>8.</em><em> f(x) = - 3x² - 4x + 8</em>

<em>f(6) = - 3×6² - 4×6 + 8</em>

<em>= - 3×36 - 24 + 8</em>

<em>= - 108 -16</em>

<em>= - 124</em>

<em />

<em>9. </em><em>g(x) = √(x - 6)</em>

<em>g(15) = √(15 - 6)</em>

<em>= √9</em>

<em>= 3</em>

<em />

<em>10. </em><em>h(x) = 2ˣ</em>

<em>h(-3) = 2⁻³</em>

<em>= 1/2³</em>

<em>= 1/8</em>

What is 3/8x + 15/2=18
mart [117]


Let's solve for x --

Isn't it always a little easier to solve a math problem with starting by rewriting the equation?

3/8x + 15/2 = 8

Step 1) Subtract 15/2 from both sides

3/8x + 15/2 - 15/2 = 8 - 15/2

3/8x = 1/2

Step 2) Multiply both sides by 8/3

(8/3) × (3/8x) = (8/3) × (1/2)

x = 4/3

FINAL ANSWER -

x = 4/3
