Step-by-step explanation:
350 chocolate 1599 of cookies
Step-by-step explanation:
c= box of chocolates
k=box of coockies
k< 550+3c , so k-3c<550
k+c< 1950
k-3c<550
I will multiply the second by 3
k - 3c < 550
3k +3c < 5850
ADD BOTH
4k < 6400
k < 1600 Cookies should be less than 1600
Since cookies yield more than chocolates , to maximize profit they need to sell the maximum amount of cookies they can
1599 +350= 1949 (less than 1950)
The amount of cookies produced must be no more than 550 boxes plus 3 times the number of chocolates produced.
1599< 3(350) +550= 1050+550=1600)
1599<1600
1599 is at least double of 350 (it could be more than double)
Multiply first equaton by -1 and add to first
-2x+y=7
<u>4x-y=-4 +</u>
2x+0y=3
2x=3
divide 2
x=3/2
sub
2x-y=-7
2(3/2)-y=-7
3-y=-7
minus 3
-y=-10
negative 1 times both sides
y=10
(3/2,10)
(1.5,10)
B is ansre
Answer:
Step-by-step explanation:
$15 × 0.75 × 1.04 = $11.70
$25 × 0.75 × 1.04 = $19.50
$37 × 0.75 × 1.04 = $28.86
$65 × 0.75 × 1.04 = $50.70
Answer:
The first image.
x | y
-4 | 0
0 | 20 <--- When x = 0, the y value is the y-intercept.
4 | 40
8 | 60
Step-by-step explanation:
To check the slope, we can use the equation (y₂ - y₁) ÷ (x₂ - x₁) using any two pairs given. For this example, I'll use (-4, 0) and (4, 40).
x₂ y₂ x₁ y₁
(0 - 40) ÷ (-4 - 4)
(-40) ÷ (-8)
<u>Slope = 5</u>
