Answer:
x + y = 36 (1)
7x + 4y = 216 (2)
Step-by-step explanation:
Quanrity of Holiday blend = 36 pounds
Cost per pound of the blend = $6.00
Cost of chocolate chips = $7.00 per pound
Cost of pretzels = $4.00 per pound
Let
Pounds of chocolate chips = x
Pounds of pretzels = y
x + y = 36 (1)
7x + 4y = 36 × $6.00
7x + 4y = 216 (2)
The system of equation is
x + y = 36 (1)
7x + 4y = 216 (2)
They would be (x+6) and (x+2).
If you FOIL those out you indeed get x^2+8x+12.
Answer:
y = 8x-37
Step-by-step explanation:
y=mx+c
We know the slope m
y=8x+c
We know a point on the line (5,3). Substitute this in for x and y
3 = 8(5) +c
3 = 40+c
3-40 = 40+c-40
-37 =c
y = 8x-37
The website first had 200 subscribers, they gained 40 which makes it 240 and then lost 10 which is 230. 230x5= 1,150. So Adriano’s website earned $1,150
Here is my answer:
a. 9x + 1
b. 9x + 57
c. 63x - 42
d. 63x - 6
