Harry reads equal numbers of pages of a book every week. The graph shows the number of pages of the book left to read, y, after

horsena [70]

Answer:

$y=-55x+275$

Explanation:

The given points are:

(0, 275)
(1, 220)
(2, 165)
(3, 110)
(4,55)
(5, 0)

Since a straight line joins all the points, the equation that models the relationship is linear and you can find the slope-intercept equation which has the general form:

$y=mx+b$

Where:

$m$ is the slope

$b$ is the y-intercept

1. Find the slope

You can use any two ordered pairs.

m = rise/run = Δy/Δx = [220 - 275] /[1 - 0] = - 55

2. Find the y-intercept

The y-intercept is the value of y when x = 0; thus it is 275.

b = 275

3. Substitute in the slope-intercept equation

$y=-55x+275$

That is the last option.

Whats the surface area of the cube

ArbitrLikvidat [17]

Answer:

93.75 cm²

Step-by-step explanation:

The linear ratio = 1 : 2.5

The area ratio = 1² : 2.5² = 1 : 6.25

surface area = 15 × 6.25 = 93.75 cm²
