Answer:

the number of hours does sidney skate in all is 9.8 hours

Step-by-step explanation:

The computation of the number of hours does sidney skate in all is as follows:

= Last month + this month

$= 1 \frac{1}{10} + 8 \frac{7}{10}\\\\= \frac{11}{10} + \frac{87}{10}\\\\= \frac{98}{10}$

= 9.8 hours

Hence, the number of hours does sidney skate in all is 9.8 hours

A) What is the equation of the line that passes through the given pair points in slope-intercept form?

lesya [120]

The slope-intercept form:

$y=mx+b$

m - slope

b - y-intercept

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (2, 5.1) and (-1, -0.5). Substitute:

$m=\dfrac{-0.5-5.1}{-1-2}=\dfrac{-5.6}{-3}=\dfrac{5.6}{3}=\dfrac{56}{30}=\dfrac{28}{15}$

Therefore we have:

$y=\dfrac{28}{15}x+b$

Put the coordinates of the point (-1, -0.5) ot the equation:

$-0.5=\dfrac{28}{15}(-1)+b$

$-0.5=-\dfrac{28}{15}+b$ multiply both sides by 2

$-1=-\dfrac{56}{15}+2b$ add $\dfrac{56}{15}$ to both sides

$\dfrac{41}{15}=2b$ divide both sides by 2

$b=\dfrac{41}{30}$

Answer: $\boxed{y=\dfrac{28}{15}x+\dfrac{41}{30}}$

-------------------------------------------------------------------------

We have the points (-2, 3) and (3, -4).

Calculate the slope:

$m=\dfrac{-4-3}{3-(-2)}=\dfrac{-7}{5}=-\dfrac{7}{5}$

Therefore we have:

$y=-\dfrac{7}{5}x+b$

Put the coordinates of the point (-2, 3) to the equation of a line:

$3=-\dfrac{7}{5}(-2)+b$

$\dfrac{15}{5}=\dfrac{14}{5}+b$ subtract $\dfrac{14}{5}$ from both sides

$\dfrac{1}{5}=b\to b=\dfrac{1}{5}$

Answer: $\boxed{y=-\dfrac{7}{5}x+\dfrac{1}{5}}$

Last week you worked the following hours: Monday, 5 ½ Wednesday, 6 ¾ Friday, 4 ½ How many hours did you work in all last week?

crimeas [40]

Adding up the whole hours first is 5+6+4 = 15. Adding the fractions is 1/2 + 3/4 + 1/2 is 1 3/4
This is 16 3/4 (answer c)
