Answer:
y = (-3/2)x + 7/2
Step-by-step explanation:
Find the slope of this line first.
As you move from the first point to the second, x (the 'run') increases by 6 and y (the 'rise') decreases by 4 (from 3 to -1). Thus the slope is
m = rise/run = -6/4 or -3/2.
Find b for this situation, using y = mx + b, m = -3/2, y = -1 and x = 3:
-1 = (-3/2)(3) + b. Multiply all three terms by 2:
2(-1) = -9 + 2b, or 7 = 2b. Then b = 7/2, and the desired equation is
y = (-3/2)x + 7/2
Answer:
25.5
Step-by-step explanation:
first find the area od the rectangle than the triangle.
to find the area count the number of squares and use A=b*h
than do the same for the triangle using A=.5*b*h
15=3*5
10.5=.5*3*7
10.5+15=25.5
Answer:
a) P = 6x + 13//
b) i) x = 5//
ii) 9//
Step-by-step explanation:
a) P = 2(x+2) + 2(2x-1) + 3 + 8 m
= 2x+4 + 4x-2 + 3 + 8
= 6x + 13//
b) i) P = 43 m
43 = 6x + 13
43-13 = 6x
<u>3</u><u>0</u> = <u>6</u><u>x</u><u> </u>
6 6
x = 5//
ii) longest side = (2x-1) m
2 × 5 - 1
10-1 = 9//
Answer:
Quick Market
Step-by-step explanation:
You need to set up the problem in fraction form or 3/1.05 and 5/1.15
Then you need for the numbers to have the same denominator.
After doing that the fraction would look like 114/39.9 for Quick Market and 173.48/39.9 for Stop and Save.
So Quick Market costs less.
