Answer:

x= -2 and x= -1

Step-by-step explanation:

We are given two functions f(x)=2^{-x} and g(x)=-2x.

The table for the values of the functions is given as,

 x         f(x)=2^{-x}           g(x)=-2x

−3                8                                       6

−2                4                                       4

−1               2                                         2

0                1                                         0

1               12                                       −2

2               14                                      −4

3               18                                      −6

From the table, we see that,

x= -2 and x= -1, the values of the functions are same.

i.e. f(-2) = g(-2) and f(-1) = g(-1).

So, the correct answer for which f(x) = g(x) are x= -2 and x= -1.

Answer:

A. (0, -2) and (4, 1)

B. Slope (m) = ¾

C. y - 1 = ¾(x - 4)

D. y = ¾x - 2

E. -¾x + y = -2

Step-by-step explanation:

A. Two points on the line from the graph are: (0, -2) and (4, 1)

B. The slope can be calculated using two points, (0, -2) and (4, 1):

slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{1 -(-2)}{4 - 0} = \frac{3}{4}

Slope (m) = ¾

C. Equation in point-slope form is represented as y - b = m(x - a). Where,

(a, b) = any point on the graph.

m = slope.

Substitute (a, b) = (4, 1), and m = ¾ into the point-slope equation, y - b = m(x - a).

Thus:

y - 1 = ¾(x - 4)

D. Equation in slope-intercept form, can be written as y = mx + b.

Thus, using the equation in (C), rewrite to get the equation in slope-intercept form.

y - 1 = ¾(x - 4)

4(y - 1) = 3(x - 4)

4y - 4 = 3x - 12

4y = 3x - 12 + 4

4y = 3x - 8

y = ¾x - 8/4

y = ¾x - 2

E. Convert the equation in (D) to standard form:

y = ¾x - 2

-¾x + y = -2

WHAT NUMBER MUST BE ADDED TO BOTH THE NUMERATOR AND DENOMENATOR OF 3/7 TO OBTAIN A FRACTION EQUAL TO 7/9?
yan [13]

Answer:

Add 22/63

Step-by-step explanation:

3/7 + n = 7/9

<u>Step 1:  Subtract 3/7 from both sides</u>

3/7 + n - 3/7 = 7/9 - 3/7

n = 49/63 - 27/63

n = 22/63

Answer:  Add 22/63
