Answer:
The equation would be y = -1/5x + 5
Step-by-step explanation:
To find the equation of this new line, we first need to identify the slope of the first line. We do this by putting it into slope intercept form.
x + 5y = 10
5y = -x + 10
y = -1/5x + 2
In slope-intercept form, the slope is always the coefficient of x. This makes the slope of the first equation -1/5. Since parallel lines have the same slope, our new slope will also be -1/5.
Given that and the point, we can solve for the equation using point-slope form.
y - y1 = m(x - x1)
y - 6 = -1/5(x + 5)
y - 6 = -1/5x - 1
y = -1/5x + 5
Answer:
8(15-m)
Step-by-step explanation:
By looking at the options, we can understand that the right one is 8(15-m), since we need to multiply the time by the number of question.
Also, we can check that result by arranging an equations usint the total time.
55 = 3m - 8(15-m)
55 = 3m - 120 + 8m
55 = 11m - 120
55 + 120 = 11m
175 = 11m
m = 175/11 = 15.91
55 = 3*15.91 - 8(15-15.91) = 47.73 - 120 + 127.28 = 55.01 ≈ 55
