Answer:
1. $22.8 rounded to the nearest cent.
2. x =
Step-by-step explanation:
1. If we are using a linear model. We need to know the slope and the y intercept
y = mx + b The y-intercept would be 15. The slope would be how much the price of the stock increased over a period of time. The stock increases $.75 in 4 months or $0.1875 per month.
y = .1875x + 15 If we used this equation we can see that in four months the price of a share would be 15.75.
y = .1875(4) + 15
y = 15.75 Now we will do the same thing, but for 42 months
y = mx + b
y = .1875(42) + 15
y = 22.875 Rounded to the nearest penny would be 22.88
2. 2(4x + 2) - (x -4) = 3(x+2) Use the distributive property
8x + 4 -x + 4 = 3x + 6 Combine like terms
7x + 8 = 3x + 6 Subtract 3x from both sides
4x + 8 = 6 Subtract 8 from both sides
4x = -2 Divide both sides by 4
x = =

Answer:
Please refer to the attached graph
Step-by-step explanation:
Knowing the following:
X = amount of money donated to the city youth fund
Y = amount of money donated to the educational growth foundation
We can write the statements in form of equations:
"Will donate up to $500, the money will be divided between two charities"
(a)
"The amount donated to the educational growth foundation to be at least four times the amount donated to the city youth fund"
(b)
If we graph both equations we can see the area where both conditions are met (see graph attached)
Where the blue line is (a) and the red line is (b)
Shaded area represent all the possible solutions for the donations, for example:
X=100 and Y=400 or
X=50 and Y=200, etc.
