Based on the given table, you can notice that the rate of change of the number of pages read related to the number of hours, is 120 pages each 3 hours.

Then, to determine the number of pages read for 15 hours, consider that after 12 hours Sarah read 480 pages. After 3 more hours, that is, for 15 hours of reading, Sarah read 120 pages more, that is, she read 480+120=600 pages.

Hence, the answer is 600

Answer:

1) gradient  (00) (-2 4) = y2-y1 / 2-1 = 4/-2 = -2  m = -2/1  means = m = -2  (negative slope)   2)  gradient  y2-y1 / x2-x1 = 3-0 / 2-0  = 3/2 = (1 1/2)/1   m = 1 1/2  (positive slope) we use the formula y-values divided by the change in the x-values.    The equation of the gradient each goes like this 1) y = -2x   as y is at origin nothing else to add     The equation of the gradient each goes like this 2) y = 1  1/2x     The equation of the point formula  1) we take the y -y1 = m (x +x 1)  =  y-0 = -2x (x +0)  (as m = -2) y = -2(x +0)   and  The equation of the point formula  2)  y - 0 = m ( x +x1)     y - 0 = 1 1/2( x +0)  = y = 1 1/2( x +0)

What is the slope of the line passing through (1, 2) and (3, 8)?
saveliy_v [14]

Answer:

Option C is correct.

Step-by-step explanation:

Points given are

(1,2) and (3,8)

The formula used for slope is:

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

x₁ = 1, x₂=3, y₁=2 and y₂=8

m=\frac{8-2}{3-1}\\m=\frac{6}{2}\\m=3

So, slope =3

Option C is correct.

musickatia [10]

Step-by-step explanation:

many things are possible.

the only thing we must not do is mixing the addition elements with the multiplication elements.

but we could change the expression to

3×(3×8) + 5

or

5 + (3×3)×8

or

5 + (3×8)×3

and so on, and it would always be the same result.
