90 volume because 3 multiples by 30 = 90
Answer:
when they are intersecting at a 90 degree angle.
Step-by-step explanation:
when lines intersect, they just cross over one another at any point. but with perpendicular lines, they have to be at a right angle. an example of this is a square. all of its corners are perpendicular
Complete question :
Complete the tables to relate the numbers of pairs of jeans to the cost of the jeans at each store. Assume that Tim is placing a single order, and
ignore any taxes.
Answer:
$24, $72
$50
Step-by-step explanation:
From the table :
At local store :
2 pair of jeans cost $48
Cost of a pair :
Cost of 2 pairs / number of pairs
$48 / 2 = $24
Cost of 3 pairs :
Cost per pair * number of pairs :
$24 * 3 = $72
At online store :
Cost of Jean include a fixed fee of $6
Cost of one pair of Jean = $28
Actual cost of Jean :
$28 - $6 = $22
Hence, cost of 2 pair of jeans:
($22*2) + $6
$44 + $6 = $50
Answer:
6/7
Step-by-step explanation:
If you want the slope of the line on a graph when x is the independent variable, then solve for y:
-28y = -24x +14 . . . . . . . . . . . subtract the x-term
y = (-24/-28)x +14/(-28) . . . . . divide by the y-coefficient
y = 6/7x -1/2
The "rate of change" is the coefficient of x, 6/7.
(-2,4) (0,4) (-2,7) are the co ordinates
