Answers
Answer:
y = -2x
Step-by-step explanation:
since the y-int starts at 0, you would go down 2 (negative) and to the right by 1, 2/1=2
use the equation y=mx+b to find the equation of a graph
m is the slope and b is the y-int
you can also use the method rise/run, where in this case, the rise (down when it’s a negative) is -2 and the run (across) is 1
2 represents the change in y and 1 represents the change in x
when finding the equation of a graph, always check the y-axis for the point then start there. that represents your y-int. then you look for a solid point and see how much units away across and up or down it is from the y-int.
in this case, i went to the point (1, -2).
hope this helps !!

Price-club sells a 12-ounce box of crackers for $2.59 and Shop Mart sells a 1-pound box of crackers for $4.68. The unit price at Price-Club is $ per ounce, and the unit price at Shop Mart is $ per ounce.
Answers
Answer:
$0.216 and $0.293
Step-by-step explanation:
Given,
Price club sells 12 ounce box = $2.59
Shop mart sells a 1 pound box = $ 4.68.
We have to find the unit price at Price club and Shop mart.
We know that 1 Pound = 16 ounce
Unit price at Price-club = [tex]\dfrac{2.59}{12}[/tex]
= $0.216
Unit price at Shop Mart= [tex]\dfrac{4.68}{16}[/tex]
= $0.293

Sierra’s ice cream shop made $45 before she had to close early when the power went out. She realized she lost Two-thirds of a dollar each hour when the shop was closed. The expression that models this situation is 45 minus two-thirds h. What was Sierra’s profit if the shop was closed for 6 hours?
Answers
Answer:
Sierra's profit was $41.
Step-by-step explanation:
Sierra realized she lost two-third of a dollar each hour when the shop was closed.
The expression that models this situation is, ............. (1)
Now, we have to calculate Sierra's profit if the shop was closed for 6 hours.
So, putting h = 6 hours in the equation (1) we get,

Answer:
[tex]x=54.6[/tex]
Step-by-step explanation:
Because ΔABC is similar to ΔSTU, we know that their corresponding sides are proportional. Therefore, we know that [tex]\frac{AB}{AC}=\frac{SU}{ST}[/tex]. We are given that [tex]AB=x[/tex], [tex]AC=21[/tex], [tex]SU=13[/tex], and [tex]ST=5[/tex]. After substituting the given values into the proportion and solving for [tex]x[/tex], we get:
[tex]\frac{AB}{AC}=\frac{SU}{ST}[/tex]
[tex]\frac{x}{21} =\frac{13}{5}[/tex] (Substitute given values into the proportion)
[tex]5*x=13*21[/tex] (Cross-Products Property)
[tex]5x=273[/tex] (Simplify)
[tex]\frac{5x}{5}=\frac{273}{5}[/tex] (Divide both sides of the equation by [tex]5[/tex] to get rid of [tex]x[/tex]'s coefficient)
[tex]x=54.6[/tex] (Simplify)

Complete the equation to show how many thirds are equivalent to
8/12 = ?/3
Answers
Answer:
[tex]\frac{2}{3}[/tex]
Explanation:
What we need to do is to convert [tex]\frac{8}{12}[/tex] into a new - but still equal - fraction, one with a denominator of 3. In order to convert a fraction, you either divide or multiply both the denominator and the numerator by the same number.
We know that the answer has to be a fraction with the denominator of 3. Take a look at the denominator of [tex]\frac{8}{12}[/tex] - it's 12. Ask yourself: 12 divided by what number equals 3? That number would 4.
So, divide 8 by 4 as well and you would get 2. Therefore, the numerator would be 2 and the answer is [tex]\frac{2}{3}[/tex].

Step-by-step explanation:
First step to any algebraic equation is to combine like-terms. This would mean that we would have to subtract 4b from both sides, I'm assuming its supposed to be plus ten and you just typed it wrong but, we get 5b+15=10 here we subtract 15 from both sides and get 5b=-5. Now we isolate the variable b, getting b=-1.

Group of answer choices
0, 7
-7, 7
7, 14
-7, 14
Answers
Answer:
The correct answer is: -7, 7
Step-by-step explanation:
Given numbers are:
-7, 0, 7, 14
We have to check all pairs of numbers with respect to sum to check that which pair of numbers sums up to zero. So first of all, we will take -7 and will find its sum with other numbers.
So,
[tex]-7+0 = -7\\-7+7=0\\-7+14 = 7[/tex]
We can see that the sum of -7 and 7 is zero.
Hence,
The correct answer is: -7, 7

At 8:00 A.M., the temperature is 53 °F. At 11:00 A.M., it is 69 °F.
What is the average change in temperature per hour?
Answers
69-53=16 degrees
11-18=3 hours
16/3= 5.33333
5.33 F is the average change in temperature per hour.
What is Mean?The sum of all values divided by the total number of values determines the mean (also known as the arithmetic mean, which differs from the geometric mean) of a dataset. The term "average" is frequently used to describe this measure of central tendency.
Given, At 8:00 A.M., the temperature is 53 °F. At 11:00 A.M., it is 69 °F.
Since there is a Sum change in temperature in 3 hours
From the formula of average:
Average change = total change/ time taken
in our case
Total change = 69 - 53
Total change = 16 F
Total time taken = 11 - 8
Total time taken = 3
Thus Average = 16/3
Average = 5.3333
Therefore, the average change in temperature per hour is 5.33 F.

Answers
Answer:
w1= -8, w2 = -4
Step-by-step explanation:
Answer: [tex]w^{2} + 13w + 36 = (w + 4)(w + 9)[/tex]
Step-by-step explanation:
[tex]w^{2} + 13w + 36 = (w + 4)(w + ?)[/tex]
w (w + ?) +4 (w + ?)
w² + ?w + 4w + ?
4w + ?w = 13w
Subtract both sides by 4w
?w = 9w
? = 9
4 (?) = 36
Divide both sides by 4
? = 9
[tex]w^{2} + 13w + 36 = (w + 4)(w + 9)[/tex]
