\LARGE{ \underline{ \orange{ \rm{Required \: answer:}}}}

Some functions in variable x is given to us. And the value of the polynomial in x is also given, we need to find the value of x in each case.

GiveN:

  1. f(x) = 6x + 9, f(x) = 21
  2. g(x) = -1/2x + 3, g(x) = -1

What to find?

  • We need to find the value of x in each case.

Step-wise-Step Explanation:

1) <u>f(x) = 6x + 9, f(x) = 21</u>

⇒ f(x) = 21

⇒ 6x + 9 = 21

⇒ 6x = 12

⇒ x = 2

Value of x in this case is <u>2</u><u>.</u>

2) <u>g(x) = -1/2</u><u> </u><u>x</u><u> + 3, g(x) = -1</u>

⇒ g(x) = -1

⇒ -1/2 x + 3 = -1

⇒ -1/2 x = -4

⇒ 1/2 x = 4

⇒ x = 8

Value of x in this case is <u>8</u><u>.</u>

storchak [24]

Answer:

seconds

Step-by-step explanation:

h(t) = -16t² + 32t +8

0 = -16t² + 32t +8

0 =-0.125(-16t² + 32t+8)

0=2t²-3t-1

0=2t²-2t-t-1

Group

0=(2t²-2t)(-t-1)

0=2t(t-1)-1(t+1)

0=(2t-1)(t-1)(t+1)

0=2t-1                                        0=t-1                             0=t+1

1/2(1)=(2t)1/2                              0+1=t-1+1                        0-1=t+1-1

0.5=t                                            1=t                                 -1=t

t=0.5                                             t=1                                  t=-1

Look at this graph:
MA_775_DIABLO [31]
<h2>Answer:</h2>

The Slope is \frac{2}{3}\\

<h2>Explanation:</h2>

Notice that both the points, (0,20) and (20,50), are on the line. So we can use those points to calculate the slope. Recall that that slope of the line m can be calculated by \frac{y_2 -y_1}{x_2 -x_1}\\ if we have the points, (x_1,y_1) and (x_2,y_2).

<h3>Calculating for the slope of the line:</h3>

Given:

(0,20)

(20,50)

m = \frac{50 -20}{20 -0} \\ m = \frac{30}{20} \\ m = \frac{2}{3}
