Answer:
They should purchase the snack with the purple box. This is the answer for 23, i don't know what 24 is sorry.
Step-by-step explanation:
24÷3=8
8×5=40
so the first snacks would cost them $40.
then:
24÷4=6
6×6=36
so the second snacks would cost them $36
Factor 2x^4 - 7x^3 -27x^2 + 63x + 81
Write as a Set of Linear Factors
Over the complex numbers
(X+3) (x-3) (x+1) (2x-9)
<span>You need to set up 2 equations for this, a system to be exact
let x represent the cheaper phone and y represent the upgraded phone
for store costs you will have
5x+25y=200
for selling prices you will have 30x+100y=900
set these two equations together
5x+25y=200
30x+100y=900
multiply the first one by -4 and add them
-20x-100y=-800
30x+100y=900
10x=100
x=10
10 cheaper phones, plug into any equation again
5(10)+25(y)=200
y=6<<<6 upgraded phones</span>
Answer:
y = -3x +10 Step-by-step explanation:
y+2 = -3(x-4)
y+2 = (-3*x) + (-3*-4)
y+2 = -3x + 12
^ -2 = . ^ -2
y = -3x +10
