Answer:

The value of given expression is -22.

Step-by-step explanation:

We are given attached graph with the question.

The graph consist of plot for two function y = f(x) and y= g(x).

We need to evaluate the value of expression:

-3\times f(-8) + 7\times g(2)

From the given graph, it is easy to calculate value for f(-8) and g(2).

From graph:

f(-8) = -2

g(2) = -4

These values were obtained by looking the corresponding y-value for given x-values from the graph.

Putting the values in the expression, we get:

(-3)\times (-2) + 7\times (-4) = 6 - 28 = -22

Hence, the value of given expression is -22.

Answer:

-22

Step-by-step explanation:

-3•f(-8)+7•g(2)=

The value of f(x) at x=-8 is

f(-8) = -2

The value of g(x) at x=2 is

g(2) = -4

Substituting these values into the equations

-3 * -2 +7*-4

6 -28

-22

Set the two expressions equal to each other.

7x + 3 = 9x

Simplify, isolate the x, subtract 7x from both sides

7x (-7x) + 3 = 9x (-7x)
3 = 2x

Set the equation = 0, subtract 3 from both sides

3 (-3) = 2x (-3)

0 = 2x - 3

2x - 3, or D, should be your answer

The circle shows the radius of 12mm what is the circumference
gulaghasi [49]

Answer:

24π or about 75.4 mm

Step-by-step explanation:

The circumference of a circle is denoted by C = 2πr, where r is the radius.

Here, we see that r = 12, so plugging this in:

C = 2πr

C = 2π * 12 = 24π ≈ 75.4 mm

The answer is thus 24π or about 75.4 mm.

Determine the line that is perpendicular to y = 1/9x - 2/3
ANTONII [103]

Answer:

A

Step-by-step explanation:

Perpendicular lines have a relationship between their slopes. Their slope are negative inverses of each other. This means is one is 3 then the negative reciprocal is the other or -1/3. The slope here is 1/9 so the perpendicular slope is -9. Slope is always attached to the x term so A is the solution.
