1. Which situation could be represented by y = 4x + 7?
a student started with $4 and saved $7 per week.
A package costs $7 plus $4 per pound to ship.
A skateboard weighs 4 pounds plus 7 ounces.
A recipe calls for 7 cups of flour and 4 cups of sugar.
2. What is the equation of the line through (5,8) and (2,2)?
y = 2x + 2
y = 2x - 2
y = 5x - 8
y =8x - 5
3. The slope of a line is -1/3 and the y-intercept is 3. What is the equation of this line?
y = 1/3 + 3
y = -1/3 + 3
y = 3x - 3
y = 3x - 1/3
4. What is the equation of the line that has a slope of 2 and goes through (3,7)?
y = 2x + 3
y = 1/2x + 7
y = 2x + 1
y = -2x + 1

Isabella deposited $500 into a savings account at a local bank that earned 5% interest per year. How much interest does she earn in her first year?
Answer:
$25
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 5%/100 = 0.05 per year,
putting time into years for simplicity,
12 months ÷ 12 months/year = 1 years,
then, solving our equation
I = 500 × 0.05 × 1 = 25
I = $ 25.00
The simple interest accumulated
on a principal of $ 500.00
at a rate of 5% per year
for 1 years (12 months) is $ 25.00.

William has a sticker album. Some pages have 1 sticker on them, and other pages have 2 stickers on them. If William has 18 stickers, how many different ways can he put the stickers in the album?
Answer:
6 ways
Step-by-step explanation:
William has a sticker album.
We are told in the question that:
Some pages have 1 sticker on them, and other pages have 2 stickers on them. If William has 18 stickers
The many different ways that can he put the stickers in the album is calculated as:
18 stickers ÷ ( 1 stickers + 2 stickers)
= 18 ÷ 3
= 6 ways
Therefore, the different ways that he can put the stickers in the album is 6 ways

Which expression is equivalent to 16^2 − 36? (Explain)
A. 4(2 − 3)(2 − 3)
B. 4(2 + 3)(2 − 3)
C. (4 − 6)(4 − 6)
D. (4 + 6)(4 + 6)
Answer:
4(2x-3)(2x + 3)
Step-by-step explanation:
Here, we want to simplify the given expression
we can have;
16x^2-36
= 4(4x^2 -9)
we can use the difference of two squares
where;
a^2 - b^2 = (a-b)(a + b)
= 4(2x-3)(2x+ 3)

Step-by-step explanation:
Which of these is a correct identity?
x + 4x = 5x
6x = 18
2x + 1 = 7
7x + 9 = x
Answer:
x + 4x = 5x
Step-by-step explanation:
An identity is a mathematical equation that is always true (here - for all possible x's).
a). x + 4x = 5x; this is true, because for any possible x
x+4x = (1 + 4)x = 5x; there's not much to add.
b). 6x=18; evaluates to
x = 3; so it only works for one x, not all possible xs.
c). 2x + 1 = 7
2x = 6
x = 3; so it only forks for one x
d). 7x + 9 = x
6x + 9 = 0; we could compute the exact x it works for from here, but suffice to say this doesn't work for x = 0.
In between these given equations, x + 4x = 5x is the correct identity here.
What is an identity?"An identity is an equality relating one mathematical expression A to another mathematical expression B, such that A and B produce the same value for all values of the variables within a certain range of validity."
Given equations are:
1. x + 4x = 5x
⇒ 5x = 5x
This equation is true for all values of 'x'.
Hence, this is a correct identity.
2. 6x = 18
⇒ x = 3
This equation is true when x = 3.
3. 2x + 1 = 7
⇒ 2x = 6
⇒ x = 3
This equation is true when x = 3.
4. 7x + 9 = x
⇒ 6x = - 9
⇒ x = - 9/6
⇒ x = - 3/2
This equation is true when x = - 3/2.

Answer:
x = - 6, x = 4
Step-by-step explanation:
Given
x² + 2x - 24 = 0
Consider the factors of the constant term (- 24) which sum to give the coefficient of the x- term (+ 2)
The factors are + 6 and - 4 , since
6 × - 4 = - 24 and 6 - 4 = + 2 , then
x² + 2x - 24 = (x + 6)(x - 4) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 6 = 0 ⇒ x = - 6
x - 4 = 0 ⇒ x = 4
