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>

How do you divide 50 by 60 and get 85
Ratling [72]

you cannot get that answer.... when you divide. Put the number into a fraction first so, it makes it easier to see what you are doing. So,\frac{50}{60}.Now simplify the cross off the zero from the top and the bottom to get\frac{5}{6}. So, \frac{5}{6} will give you 0.83333333333...3.

They take 5 days to drive 679 miles to Seattle, how many miles will they drive each day?
Kisachek [45]

If they take 5 days to drive 679 miles to Seattle. Then the number of miles that they drive each day will be 135.8 miles per day.

<h3>What is speed?</h3>

The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.

We know that the speed formula

Speed = Distance/Time

They take 5 days to drive 679 miles to Seattle.

Then the number of miles that they drive each day will be

→ 679 / 5

→ 135.8 miles per day.

More about the speed link is given below.

Determine the midpoint between the two points x(4,-6) and y(-2,8)
ikadub [295]

Answer:

p(a, b) = (1, 1)

Step-by-step explanation:

Midpoint formula is

p(a, b)=(\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2} ) ---------------(1)

Here

(x_1, y_1) = (4, -6) \ \ \ and \ \ \ (x_2, y_2) = (-2, 8)

Substituting values in equation (1)

p(a, b)=(\frac{4 - 2}{2}, \frac{-6 + 8}{2} )

p(a, b) = (1, 1)
