Answer:
The required equations which represents the relationship between x and y is 
.
Step-by-step explanation:
Consider the provided information.
Dalia makes a cranberry apple punch that contains 20%, percent real juice by mixing x gallons of a cranberry drink with y gallons of an apple drink.
This can be written as: 
The cranberry drink contains 40 percent real juice and the apple drink contains 10 percent real juice.
This can be written as: 
Now both the equation are equal.
Hence, the required equations which represents the relationship between x and y is .
Answer:
D.) $320
Step-by-step explanation:
4% of 8,000
so
0.04 x 8,000
= 320
Answer:
x = 20
Step-by-step explanation:
x = 50/2.5 = 2.5x = 50
Answer:
The second term of the binomial factor should be 3c instead of 3.
Step-by-step explanation:
Distributive property:
a*b + a*c = a*(b +c)
3b + 9c = 3*b + 3* 3 *c = 3*(b + 3c)
Answer:
y = 4.125x + 496.25
Step-by-step explanation:
Set the data up as points. Then deal with the points.
Givens
(30,620)
(70,785)
y2 = 785
y1 = 620
x2 = 70
x1 = 30
Formula
Slope = (y2 - y1) / (x2 - x1)
Solution
Slope = (785 - 620)/(70 - 30)
Slope = 165 / 40
Slope = 4.125
===================
Now you need the y intercept. Either one of the two given points will give you that.
y = 620
x = 30
m = 4.125
y = mx + b
620 = 4.125*30 + b
620 = 123.75 + b
620 - 123.75 + b
b = 496.25
