All answer choices show the boundary line going through (0,-2) and (2,2). This  is because y = 2x-2 goes through these two points. We make the boundary line a dashed line to indicate that solution points are not found on the boundary (because there is no "or equal to" portion in the inequality sign).

The shading is below the boundary line because of the "less than" sign. Any solution point (x,y) will have its y coordinate smaller than the y coordinate of points on the boundary line. So if (a,b) is on the boundary, then (a,c) is a solution where c < b.

In summary, the graph has a dashed boundary line and the shading is below the boundary

Solve 3^x−5 = 9. (3 points) Select one: a. x = −3 b. x = 2 c. x = 7 d. x = 8
goldfiish [28.3K]
ANSWER

C. x=7

EXPLANATION

The given exponential equation is

{3}^{x - 5} = 9

We rewrite the right hand side as 3 raised to exponent 2.

{3}^{x - 5} = {3}^{2}

Observe that the base of both sides of the equation are equal.

We now equate the exponents.

x - 5 = 2

Solve for x,

x = 2 + 5

x = 7

The correct choice is C.

Katie is 1.52 m tall. George is 6 cm shorter than Katie. How tall is George?
lukranit [14]

Answer:

1.46 cm

Step-by-step explanation:

You have to first convert meters into centimeters to make everything easier. (1m = 100cm)

1.52 meters is 152 centimeters

152-6 = 146 cm

146 cm divided by 100 is 1.46 meters

George is 1.46 meters tall

Hope this helps! :D
