Rewriting the equation of the given line in slope-intercept form,

8x-7y=87\\\\-7y=-8x+87\\\\7y=8x-87\\\\y=\frac{8}{7}x-\frac{87}{7}

The slope of the given line is thus 8/7, and since parallel lines have the same slope, the slope of the line we want to find is also 8/7.

Substituting into point-slope form,

y+17=\frac{8}{7}(x-3)\\\\y+17=\frac{8}{7}x-\frac{24}[7}\\\\\boxed{y=\frac{8}{7}x-\frac{143}{7}}

Harry’s tv plan cost 49.99 per month plus 3.49 per first run movie how many first run movies can he watch if he wants to keep hi
KIM [24]

Answer:

He can watch 14 first run movies to keep his monthly bill to be a maximum of $ 100.

Step-by-step explanation:

Given that Harry’s TV plan cost $ 49.99 per month plus $ 3.49 per first run movie, to determine how many first run movies can he watch if he wants to keep his monthly bill to be a maximum of $ 100, the following calculation must be performed:

100 - 49.99 = 50.01

50.01 / 3.49 = X

14.32 = X

49.99 + (3.49 x 14) = 98.85

Thus, he can watch 14 first run movies to keep his monthly bill to be a maximum of $ 100.

gtnhenbr [62]

The equation would be 3.75+t=11.2 so:

3.75+t=11.2

3.75+t-3.75=11.2-3.75

t=7.45, which is 7:35.
