Is AB parallel to Bo? Explain.
Svetradugi [14.3K]

Answer:

AB parallel to CD because both lines have a slope of

of 4/3

Step-by-step explanation:

The question is not complete, there is no graph.

A graph for the question is attached below.

From the image attached below, line 1 passes through points A = (-3, -3) and point B = (0, 1) while line 2 passes through point C = (0, -5) and point D = (3, -1).

Two parallel are said to be parallel if the have the same slope. The slope of a line passing through points:

(x_1,y_1)\ asnd\ (x_2,y_2).\ The\ slope \ is\ given\ as:\\\\Slope(m)=\frac{y_2-y_1}{x_2-x_1}

Line 1 passes through points A = (-3, -3) and point B = (0, 1), the slope of line 1 is:

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

Line 2 passes through point C = (0, -5) and point D = (3, -1). the slope of line 2 is:

Slope(m)=\frac{y_2-y_1}{x_2-x_1}=\frac{-1-(-5)}{3-0}=\frac{-1+5}{3}=\frac{4}{3}

Therefore AB parallel to CD because both lines have a slope of

of 4/3

Susie has $95 to spend on renting snorkeling gear at the beach. There is a $15 flat service fee to rent the snorkeling gear alon
Stella [2.4K]

Answer:

10 hours

Step-by-step explanation:

We can actually solve this problem simply as if it were an equation instead of an inequality. We have:

15 + 8h ≤ 95

Subtract 15 from both sides:

8h ≤ 95 - 15

8h ≤ 80

Divide by 8 from both sides:

h ≤ 80/8

h ≤ 10

So, the number of hours cannot exceed 10, which means the maximum number of hours Susie can rent is 10 hours.
