Answer:
Straight-line equations, or "linear" equations, graph as straight lines, and have simple variable expressions with no exponents on them. If you see an equation with only x and y – as opposed to, say x2 or sqrt(y) – then you're dealing with a straight-line equation.
There are different types of "standard" formats for straight lines; the particular "standard" format your book refers to may differ from that used in some other books. (There is, ironically, no standard definition of "standard form".)
Answer:
$38
Step-by-step explanation:
First, you need to find out how much one can cost. To do that, you need to divide 12 by 6. You should get 2. Now you know that one can cost $2. To figure out the price of 19 cans, just multiply the price of one can by 19:
19x2 = 38
Answer:
11 m by 18 m
Step-by-step explanation:
The area is the product of two adjacent sides of a rectangle. The perimeter is twice the sum of two adjacent sides, so that sum is (58 m)/2 = 29 m.
We want to find two factors of 198 that sum to 29.
198 = 1·198 = 2·99 = 3·66 = 6·33 = 9·22 = 11·18
Of these factor pairs, only the last one has a sum of 29.
The dimensions of the pool are 11 meter by 18 meters.
Answer:
IF IT IS THE AREA THEN YOU SHOULD TIMES THEM AS IN THE 1ST SHAPE 3 X 7 X 6 THEN DIVIDE 2 SECOND 7 X 3 X 3 X 6 DIVIDE INTO 2 AND AGAIN 2
