Answers
Answer:
Check boxes 3, 4, 6, and 8.
Step-by-step explanation:
We have the equation:
[tex]y=-3x+2[/tex]
And we want to select all equations that are perpendicular to the above equation.
Remember that perpendicular lines have slopes who are negative reciprocals of each other.
Therefore, the slope of our equations must be the negative reciprocal of -3.
The negative reciprocal of -3 is 1/3. We flipped -3 to -1/3, and then multiplied by a negative.
Therefore, any equation with a slope of 1/3 is perpendicular to our original line.
Therefore, we will check boxes 3, 4, 6, and 8.

Answer:
y = 5x - 6
Step-by-step explanation:
The equation is in the form
y = mx + c ( m is the rate of change and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, - 6) and (x₂, y₂ ) = (3, 9) ← ordered pairs from the table
m = [tex]\frac{9+6}{3-0}[/tex] = [tex]\frac{15}{3}[/tex] = 5
The line crosses the y- axis at (0, - 6) ⇒ c = - 6
y = 5x - 6 ← linear equation
A spinner is divided into five colored sections that are not of equal size: red, blue, green, yellow, and purple. The spinner is spun several times, and the results are recorded below: Based on these results, express the probability that the next spin will land on blue as a decimal to the nearest hundredth.
Answers
Answer:
The probability that the next spin will land on blue is 0.12.
Step-by-step explanation:
The result of the several spins are as follows:
Color Frequency
Red 18
Blue 9
Green 18
Yellow 19
Purple 12
TOTAL 76
Compute the probability that the next spin will land on blue as follows:
[tex]P(Blue)=\frac{n(Blue)}{N}\\\\=\frac{9}{76}\\\\=0.1184211\\\\\approx 0.12[/tex]
Thus, the probability that the next spin will land on blue is 0.12.
The probability that the next spin will land on blue as a decimal to the nearest hundredth is 0.12 and this can be determined by using the given data.

The store at which Andy usually shops is having a sale. Roast beef costs $4 per pound and shrimp costs $10 per pound.
Let x = pounds of roast beef and y = pounds of shrimp
Write an inequality to represent the different possible combinations that Andy can buy if he has $96.
What is one possible combination of roast beef and shrimp that Andy can buy?
Answers
Answer:
Part 1;
10y + 4x ≤ 96
Part 2;
y = 8
x = 4
Step-by-step explanation:
1 - Write an equation
Let z equal the total price
10y + 4x = z
2 - Use that to answer the questions
"Write an inequality to represent the different possible combinations that Andy can buy if he has $96."
If Andy has $96 that means the amount the two add up two can equal 96 or be less than 96 however not any more. That means 10y + 4x must be less than or equal to 96. This is written as follows
10y + 4x ≤ 96
With this in mind we can answer the following question of what is one possible combination. To do this, lets assume
10y + 4x must equal 96
Lets make 96 divisible by 10 using our pounds of roast beef.
To do this we need to get rid of the 6; which we can do so by turning 4x into 16. 4 goes into 16 4 times.
Therefore;
10y + 4x = 96
10y + 4(4) = 96
10y + 16 = 96
- 16 - 16
10y= 80
Divide both sides by 10
y = 8
And our x when y = 8 was 4
so
x = 4

Ivy is trying to manage the money she spends on lunch. Between eating out and buying groceries for bagged lunches, she wants to keep her weekly budget to less than $50. She decides that she wants to spend at least twice as much on bagged lunches as at restaurants. What are the monetary choices for Ivy’s lunches?
Answers
Answer:
The monetary choices for Ivy’s lunches is to spend less than $16.67 at restaurants and to spend less than $33.33 on groceries in order to to keep her weekly budget to less than $50.
Step-by-step explanation:
This can be determined as follows
x = the amount of dollars spent at restaurants
y = the amount of dollars spent on groceries
Since Ivy decides that she wants to spend at least twice as much on bagged lunches as at restaurants, we have
y = 2x .................. (1)
Since Ivy wants to keep her weekly budget to less than $50, using the x and y, we have:
x + 2x < 50 ............................ (2)
We can now solve for x as follows:
3x + < 50
x < 50 / 3
x < 16.67
Substituting the x < 17 into equation (1) noting that Ivy wants to keep her weekly budget to less than $50, we have:
y < 2 * 16.67
y < 33.33
Therefore, the monetary choices for Ivy’s lunches is to spend less than $16.67 at restaurants and to spend less than $33.33 on groceries in order to to keep her weekly budget to less than $50.
You buy a pair of jeans for 25% markdown from $32.00. The sales tax is 6%. How much will you pay for the jeans?
Answers
Answer:
$25.44
Step-by-step explanation:
To find the markdown, multiply the initial cost of the jeans by the percentage of the initial price the new amount will be. If the jeans are getting a 25% markdown, then the new cost will be 75% of the initial cost. Convert 75% and then multiply it by 32:
32 * 0.75 = 24
Now that we know the price of the jeans, we can calculate the sales tax. Multiply 24 by 0.06 to find the sales tax:
24 * 0.06 = 1.44
Now add the sales tax to the new cost to get your final answer:
1.44 + 24 = 25.44
You will pay $25.44 for the jeans.
Hope this helps :)
Answer: 25.44 would how much you would have to pay for the jeans :)

The result we get when we divide the fractions, 5/8 ÷ 1/4 = D. 2 and one-half.
How to Divide Fractions Together?To divide a fraction by another fraction, simply change the division sign to multiplication sign and turn the fraction on the right of the sign upside down, such that what we have as the denominator of the fraction will now be the numerator while what we have as the numerator of the fraction will now be the denominator.
After doing this, multiply the denominators of the fractions and the numerators of the fractions.
Given the fractional expression, 5/8 ÷ 1/4, to divide, turn the fraction on your right upside down and change the sign to multiplication:
5/8 × 4/1
Multiply the denominators and also multiply the numerators of the fractions:
(5 × 4)/(8 × 1)
= 20/8
Simply further by dividing 20 by 4 and dividing 8 by 4:
4 into 20 is 5.
4 into 8 is: 2
Therefore:
20/8 = 5/2
= 2½
Therefore, 5/8 ÷ 1/4 is: D. 2 and one-half.
