Answer:
y = 3x - 8
Step-by-step explanation:
passes through (5, 7) and (4, 4)
Find slope:
(7 - 4) / (5 - 4)
= 3/1
= 3
This is your slope.
Now plug in a set of coordinates.
y = 3x + b
7 = 3(5) + b
7 = 15 + b
b = -8
Your equation is: y = 3x - 8
Check your work by plugging in the second coordinate pair.
y = 3x - 8
4 = 3(4) - 8
4 = 12 - 8
4 = 4
Your solution is correct.

Find the product of ( 2x^2 − 4x + 3 ) ( 3x + 6 ) using the box method shown below. What will the monomial be in the box marked with a B?
Select one:
a. - 12x 2
b. - x 2
c. - x
d. - 12x
Answer:
[tex]-12x^2[/tex]
Step-by-step explanation:
Think of the box method as completing a chart or a multiplication table.
We can see that box B is in the second column of the first row. The second column is labeled by -4x. The first row is labeled by 3x. So, in order to fill out box B, you have to multiply -4x and 3x together.
To do so, multiply the terms' coefficients (the numbers in front of the variable). -4 times 3 makes -12. Then, multiply the variables - just keep the variable and add their exponents. x and x both have exponents of one, which makes [tex]x^1^+^1[/tex], resulting in [tex]x^2[/tex]. Put them together and the answer would be [tex]-12x^2[/tex].
Determine whether the function is linear or nonlinear. Explain
helppppppppp
Answer:
A linear function follows a constant rate of change Here we see x moves by 4 units and that y decreases by 4 units then suddenly changes to 6 units hence 13 Is Not A functionFor 12, it is a function because it follows a consistent rate of change which is x or one unit of change.Answer:
12) The function is linear.
13) This function is not linear.
Step-by-step explanation:
13) A linear functions equation must be in y = mx + b form
When you graph the table there is no y = mx + b equation that makes a line that passes through all the points.
Two glasses of milk and 3 snack bars have a total of 63 carbohydrates (carbs), and 4 glasses of milk and 2 snack bars have a total of 82 carbs. Determine how many carbs are in one glass of milk and in one snack bar.
Answer:
Glass of milk=15 carbs
One snack bar=11 carbs
Step-by-step explanation:
×2 2m+3s=63.......................1
×1 4m+2s=82..............2
4m+6s=126
4m+2s=82
Cancel out the 4ms
6s=126
2s=82
minus top and bottom equations and remain with
4s= 44
s=44/4
s=11 ∴ one snack bar is 11 carbs
subs s=11 into equation 1
2m+3s=63
2m+3(11)=63
2m+33=63
2m=63-33
2m=30
m=30/2
m=15 ∴one glass of milk is 15 carbs
This year, students in the 9th grade are collecting dimes and quarters for a school fundraiser. They are trying to collect more money than the students who were in the 9th grade last year. The students in 9th grade last year collected $143.88. Using LaTeX: dd to represent the number of dimes collected and LaTeX: qq to represent the number of quarters, which statement best represents this situation? Group of answer choices LaTeX: 0.25d + 0.1q \geq 143.880.25 d + 0.1 q ≥ 143.88 LaTeX: 0.25q + 0.1d \geq 143.880.25 q + 0.1 d ≥ 143.88 LaTeX: 0.25d + 0.1q > 143.880.25 d + 0.1 q > 143.88 LaTeX: 0.25q + 0.1d > 143.88
Answer:
[tex]0.10d + 0.25q > 143.88[/tex]
Step-by-step explanation:
Let the total dimes collected be d.
[tex]1\ dime = \$0.10[/tex]
[tex]d\ dimes = \$0.10d[/tex]
Let the total quarters collected be q.
[tex]1\ quarter = \$0.25[/tex]
[tex]q\ quarters = \$0.25q[/tex]
[tex]Last\ Year = \$143.88[/tex]
Required
Represent as an inequality
The total collection, this year, can be represented as:
[tex]Total = 0.10d + 0.25q[/tex]
From the question, we understand that:
This year's collections is expected to be greater than last year's
This can be represented as:
[tex]Total > Last\ Year[/tex]
Substitute in the right values:
[tex]0.10d + 0.25q > 143.88[/tex]

Answer:
The answer is D, E, F or it is also D to F
Step-by-step explanation:
9514 1404 393
Answer:
A and B
Step-by-step explanation:
Speed is the change in distance divided by the change in time. That is, it is the slope of the distance vs. time curve. A steeper slope corresponds to a greater speed.
Between A and B, the slope is (30-0)/(1-0) meters/time-unit = 30 m/u.
Between B and C, the slope is (30-10)/(4-1) = 20/3 = 6 2/3 m/u.
Between C and D, the slope is 0.
Between D and F, the slope is (50-10)/(10-6) = 40/4 = 10 m/u.
The greatest slope is between A and B.
The object has the greatest speed between points A and B.
Analyze the drawing.The beam in the mobile is balanced.The cups on the right and left are equal,which means the the items can be removed and mobile still balances.This leaves 4 circles on the left,a cup and 1 circle on the right.Now the circle on the right cancels out the circle on the left,leaving three circles on the right.The logical conclusion is that the cup is equal to 3 circles

Salvador sold hats during the weekend sporting event. On Saturday, Salvador sold ( * of the total number of hats. On Sunday, he sold & ( of the total number of hats. What fraction of the total number of hats was left over?
Answer:
5/28
Step-by-step explanation:
Salvador sold hats during a weekend sporting event. On Saturday, Salvador sold 4/7 of the total number of hats. On Sunday, he sold 1/4 of the total number of hats. What fraction of the total number of hats was left over
Total number of hats = x
Hats sold on Saturday = 4/7x
Hats sold on Sunday = 1/4x
Hats left over = x - (4/7x + 1/4x)
= x - ( 16x+7x/28)
= x - 23/28x
= 28x - 23x/28
= 5/28x

In 2–4, write Yes or No to indicate whether the expressions are equivalent. 2. 10x - 3 + 2x - 5 and 4(3x - 2) 3. 3y + 3 and 9(y + 1/3) 4. 6(3x + 1) and 9x + 6 + 9x
Step-by-step explanation:
2. 10x - 3 + 2x - 5 and 4(3x - 2)
10x - 3 + 2x - 5
Upon simplifying;
10x + 2x - 3 - 5
12x - 8
4(3x - 2)
12x - 8
Both expressions are equivalent - Yes!
3. 3y + 3 and 9(y + 1/3)
9(y + 1/3)
upon simplifying;
9y + 9 (1/3)
9y + 3
3y + 3
Both expressions are not equivalent - No!
4. 6(3x + 1) and 9x + 6 + 9x
6(3x + 1)
upon simplifying;
6(3x) + 6 (1)
18x + 6
9x + 6 + 9x
Upon simplifying;
9x + 9x + 6
18x + 6
Both expressions are equivalent - Yes!
Solve the system by substitution.
y = 5x
y = 9x + 8
Answer:
(-2,-10)
Step-by-step explanation:
So if y=5x and if y=9x+8 then those should be able to equal each other (substitution):
5x=9x+8
Subtract 5x from both sides:
0=4x+8
Subtract 8 from both sides:
-8=4x
Divide both sides by 4:
x=-2
If x=-2, then we can just plug it back into the first equation:
y=5(-2)
Simplify:
y=-10
Answer:
x = -2
y = -10
Step-by-step explanation:
So if y = 5x
Then you can put that in place of the y
5x = 9x + 8
Get the x's all on one side by subtracting
-4x = 8
Divide both sides by -4
x = -2
Then insert x into the first equation, so
y = 5(-2)
y = -10

Answer:
Answer choice D
Step-by-step explanation:
So we need to get r to the right side. First we can multiply by 3 to get rid of the fraction:
3V=4[tex]\pi[/tex][tex]r^{3}[/tex]
Then we can divide both sides by 4[tex]\pi[/tex] to get r by itself:
[tex]\frac{3V}{4\pi } = r^{3}[/tex]
Then cube both sides:
[tex]\sqrt[3]{\frac{3V}{4\pi } } =r\\[/tex]

Before leaving for his book club meeting, Larry reads the last chapter in his book. The chapter is 15 pages long and contains 1,500 words. He reads the 15 pages in 10 minutes. How many words per minute does he read?
Answer: 150 wpm
Step-by-step explanation:
if he reads 1,500 words in 10 minutes, then we simply divide 1500 by 10, in order to get how many words that he can read in one minute.
1500/10 = 150
