Answer:

Kiara is correct

.............

Kiara says that the slope of the line between points B and C is the same as the slope of the line between points A and B is Correct.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Given:

From the figure

Slope between A and B = rise/ run 3/3 = 1

and, slope between B and C = 5/5 = 1

So, the slope between A and B is same as the slope between B and C.

Hence, Kiara has correct statement.

Answer:

$19.03

Step-by-step explanation:

Okay, this is a standard percentage problem, so learning how to do this is necessary. First, we have to find what 6% of $17.95 is, since of is our keyword and that means to multiply, and percentages turn into decimals:

17.95 x 0.06 = 1.08

So we have our tax, then we have to add that to our original price to get the whole thing:

17.95 + 1.08 = 19.03

So the total sale price is $19.03

2(5x-7) + 2(3x+2) = 70

x = 5

5(5)-7=  18

3(5) + 2 = 17

Answer:

Step-by-step explanation:

we have a rectangle, and the perimeter P=70

P=2L+2W

P=2(5x-7)+2(3x+2)=10x-14+6x+4=16x-10

16x-10=70

16x=70+10=80

16x=80

x=5

L=25-7=18

Applying the negative exponent rule of power, the expressions that are equivalent to the given expression, 1/81, are: B, D, and F.

The negative exponent rule states that: [tex]a^{-n} = \frac{1}{a^n}[/tex].

Thus, given the expression, 1/81, it can be rewritten or simplified as follows:

1/81 = [tex]81^{-1} = 9^{-2}[/tex] = [tex]\frac{9^8}{9^{10}}[/tex] = [tex]9^5 \times 9^{-7}[/tex]

The expressions that will be equivalent to 1/81 can be expressed, based on the negative exponent rule of power, as:

[tex]9^{-2}, \frac{9^8}{9^{10}} , 9^5 \times 9^{-7}[/tex] (option B, D, and F).
