Answer:
Slope: 0
Step-by-step explanation:
We have to find the slope of the line with the given points.
To find the slope, we would use the slope formula: m = y2-y1/x2-x1, where as "m" is the slope.
Plug in your coordinates and solve.
Solve:
m = -7 - (-7)/-2 - 4
m = -7 + 7/-2 - 4
m = 0/-6
Divide -6 from 0.
m = 0
You would notice that we have a "0" in our slope. There is no "rise" in the slope.
This means that the slope of our line would be 0.

What are the intercepts for the equation? Select both the x- and y- intercept. 2x + y = 4
Answer:
x=1 y=2
Step-by-step explanation:
Answer:
y= -2x+4
So the y intercept is 4, as its the c in this equation
I think that makes your x intercept as either 8 or 2...

Charlie wants a new pair of shoes that cost $40. His mom pays 75% of the cost and charlie pays 25%. How much do they each pay?
Answer:
Mom: $30
Charlie: $10
Step-by-step explanation:
You have to find how much percent of 40 for the price that they each pay.
His mom pays 75%, so that is $30.
And Charlie has to pay $10 because that is how much is left.
Tommy thinks the two expressions below are equivalent
-3 (6a - 5) + 4a and
22a + 15
A) Is he correct?
B) Explain why or why not?
Answer:
no, they are not equivalent expressions
Step-by-step explanation:
simplify: -3(6a - 5) + 4a = -3(6a) + (-3)(-5) + 4a = -18a + 15 + 4a = -14a + 15
-14a + 15 ≠ 22a + 15
Which is the slope of the line y=-3x + 2?
The answer is -3
Answer: -3
Step-by-step explanation:
The slope intercept form is y=mx+b
The m would be your slope
So, in this case, it's -3
Answer:
The question is of the form y=mx+c (Slope intercept form)
So comparing the equations
-3x+2=mx+c
Then we get value of m=-3
Therefore the slope is -3
Mai bought a television for $350. The tax rate is 8%. What is the total amount Mai paid for the television?
Answer:
378
Step-by-step explanation:
We know that she bought a television for $350 and the tax rate is 8%. This means the equation will be 350+(0.08*350). We can solve that equation using benchmark fractions since that's the quicker method of doing it.
To find 8% of 350, we can do 1% of 350 = 3.5 and we just multiply 3.5*8 which is 28. So we do 350+28.
You could also do 350*.08 but that's less efficent
Lisa sold 11 shirts for every 7 shirts Becky sold. If the girls sold 72 shirts in all, how many shirts did Becky sell?
Answer: 28 shirts
Step-by-step explanation:
From the question, we are informed that Lisa sold 11 shirts for every 7 shirts Becky sold. This can be expressed in a fraction as:
Lisa = 11/(11 + 7) = 11/18
Becky = 7/(11 + 7) = 7/18
If the girls sold 72 shirts in all, the number of shirts sold by Becky will be:
= 7/18 × 72
= 7 × 4
= 28

Serena is hitting golf balls at the driving range. When she hit a ball with her 9-iron, it stopped x yards in front of the 100-yard marker. She knows she can hit a ball twice that far if she uses her driver. Complete the steps below to see how far Serena can hit a golf ball with her driver.
Write an expression in terms of x that represents the distance Serena hit the golf ball using her 9-iron.
Serena knows she can hit a golf ball two times as far with her driver as with her 9-iron. Write an expression in terms of x to represent how far Serena can hit a ball using her driver.
Use the Distributive Property to expand the expression you obtained in part B.
Let’s try something a bit different. Serena hit a ball 2x yards past the 150-yard marker with her 3-iron. Write an expression in terms of x that represents this distance.
Now use the Distributive Property to factor the expression you obtained in part D.
Why do you think the operation that you performed on the expression in part E is called factoring? Use what you know about factoring numbers.

A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.

Check : x4 is the square of x2
Factorization is : (x2 + 5) • (x2 - 5)

Find what x equals 17 + 4x = -(5x + 1)
(Explanation please)
Answer:
x = -2
Step-by-step explanation:
[tex]17 + 4x = - (5x + 1)[/tex]
Distribute - 1 to (5x + 1) .
[tex]17 + 4x = - 5x - 1[/tex]
Add 1 to both sides.
[tex]18 + 4x = - 5x[/tex]
Subtract 4x from both sides.
[tex]18 = - 9x[/tex]
Divide by - 9 from both sides.
[tex] - 2 = x[/tex]

The sales tax in Sandra's town is 6.5%. If she buys 2 shirts for $23.99 each and a pair of shoes for $41.99, how much sales tax does she owe?
4.68
5.84
7.85
5.12
Answer:
5.84
Step-by-step explanation:
She has two shirts and their 23.99 each
23.99 x 2 = 47.98
Then she has a pair shoes that cost 41.99
Add
47.98 + 41.99 = 89.97
6.5% = 0.065
89.97 x 0.065 = 5.84

What is function?A function is defined as a relationship between a set of inputs, each of which has a single output. Simply put, a function is a relationship between inputs, where each input is associated with exactly one output. Each function has a domain name and a code domain or region. A function is usually denoted by f(x), where x is the input. The general representation of a function is y = f(x).

Find each unknown number. a. 12 is 150% of what number? b. 5 is 50% of what number? c. 10% of what number is 300? d. 5% of what number is 72? e. 20 is 80% of what number?
The unknown values of number for each of the expression is 8, 10, 3000, 1440, and 25.
What is Percentage?A percentage is a portion of a whole number which is expressed as a number between the range of 0 and 100 rather than as a fraction. All of a thing is 100 percent, half of it is 50 percent, and none of something is zero percent. To determine a percentage, we divide the portion of the whole through the whole of itself and multiply it by 100.
x × 150/100 = 12
x = 12 × 100/ 150
x = 1200/ 150
x = 8
x × 50/100 = 5
x = 5 × 100/ 50
x = 500/ 50
x = 10
x × 10/100 = 300
x = 300 × 100/ 10
x = 30000/ 10
x = 3000
x × 5/ 100 = 72
x = 72 × 100/ 5
x = 7200/ 5
x = 1,440
x × 80/ 100 = 20
x = 20 × 100/ 80
x = 2000/ 80
x = 25
Therefore, the values of unknown numbers are 8, 10, 3000, 1440, and 25, respectively.

Which statement about the shipping rate is true?
Shipping at the second rate will always cost $1.60 more than shipping
at the first rate.
If the weight is greater than 16 ounces, the shipping rate is $0.35 per

Answer:
A: Shipping at the second rate will always cost 1.60 more than shipping at the first rate.
Step-by-step explanation:
The following points for the function C(w) can be concluded as
The function C(w) is valid only for {w} greater than 16 ounces.The initial cost is $1.6.The cost of shipping per ounce is $0.35.What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is that the Quick Ship company uses the function C(w) to calculate the cost in dollars {C} for shipping an item weighing {w} ounces as
C(w) = 0.35W + 1.6 if {w > 16}
The given function is -
C(w) = 0.35w + 1.6 if {w > 16}
We can conclude the following points for the function C(w) -
The function C(w) is valid only for {w} greater than 16 ounces.The initial cost is $1.6.The cost of shipping per ounce is $0.35.Therefore, the following points for the function C(w) can be concluded as
