There are 112 adult-sized ponchos for $45 each and 143 kid sized-ponchos for $32 each
112 * 45 = 5,040
143 * 32 = 4,576
5,040 + 4,576 = 9,616
If the store sells all the ponchos it will receive $9,616
Answer:
B ; C; D
Step-by-step explanation:
The slope measures the rate of change in the dependent variable per unit change in the independent variable :
From the options :
Doing 4 pages of homework in 20 minutes :
The number of pages done per minute = slope
Slope = 20 / 4 = 5
To cycle 32 miles in 4 hours:.
Number of miles to cycle per hour to achieve the feat :
Slope = 32 /4 = 8
Buying 10 shirts for $80:
Cost per shirt = slope
Slope = $80 / 10
Slope = 8
Reading 72 pages in 9 hours
Number of pages read per hour :
72 / 9 = 8 pages
Answer:
"all real numbers."
Step-by-step explanation:
Subtract 13 from both sides, obtaining -5x = -5x.
This result is true for all x, so the solution set is "all real numbers."
Answer:
Y = (-3) *X - 10
solution for Y =0 ---> X = -10/3
Step-by-step explanation:
Two points:
(Y0 ; X0) = (-4 ; 2)
(Y1 ; X1) = (-2 ; -4)
There is only one line which pass for both of them, his general expresion is:
y = a*x + b --- (1)
Calculating "a": is the pending of the line.

Calculating "b":
Since every point who belongs to the line satisfied the (1) expresion, we can use it for the point (Y1 ; X1) :

<u>Final expresion</u>
Replacing in (1):
