Answer:

Step-by-step explanation:

Calculate the slope m using the slope formula

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

with (x₁, y₁ ) = (- 1, 2) and (x₂, y₂ ) = (5, 8 )

m = $\frac{8-2}{5+1}$ = $\frac{6}{6}$ = 1 → A

Tai resized a photograph that was 8 inches by 10 inches so that it would fit on a 4 inch by 4 inch page. Find the maximum dimens

Varvara68 [4.7K]

Ok so it has to be max 4 inches when resized since the max size is 4 inches

10 is max of original so
they have to be shrunk in same ratio so find ratio of shrink
10 times ratio=4
divide both sides by 10
ratio=4/10=2/5
so multiply the measuremet by 2/5 to find new dimention

8 times 2/5=16/5=3 and 1/5=3.2

new dimentions is 4 by 3.2 inches

Answer:

c) Percentages

Step-by-step explanation:

Percentages can be used to compare changes from one period to another.

In calculating a percentage change, either a percentage increase or percentage decrease, we must have both the new and old measurement of the specific quantity.

For example, let's find percentage increase of the number of students that joined a book club using the parameters below;

Original number of students = 32

New number of students = 36

We will calculate the increase using;

$Increase = original \; number - new \; number$
