Answer:
$14.00 per pound for A and $12.50 per pound for B and B is offering the better one since it has a lower cost per pound
Step-by-step explanation:
Answer:
Brand A is $14
Brand B is $12.5
Brand B is offering the better value. I know this because when you get the unit rate for Brand A it is $14. When you get the unit rate for Brand B you get $12.5. So You pay less money for Brand B then Brand A.
Step-by-step explanation:
For brand A you need to first divide 70 by 5 which equals to 14
Then you divide 105 by 12 which equals 12.5

The equation of the line in slope Intercept form is
Answers
Answer:
y = 60x + 40
Step-by-step explanation:
It is in the form of
y = mx + b
m is the slope
b is the y intercept.
The y intercept is 40, so it will be y = mx + 40.
The slope is 60, so y = 60x + 40!

For example let’s look at the first column where x is given to equal -1
If we know that x=-1 then we can substitute that for x in the given equation y= 3x+2 so now it looks like
y=3(-1)+2
The 3 and the -1 are spectated only by parenthesis meaning they are multiplied. So now it look like this:
y=-3+2
Now just add these terms together
y=-1
Now you know what goes in the y box under -1.
You can repeat this for each x value.
Let’s do one more, the box that has 0 In it. Remember this means x=0 so 0 can be put anywhere in the equation you see x.
Y=3(0)+2
Anything times 0 is zero
So you just have: y=0+2
So y=2
This would go in the box under the 0.

Write an equation of the line passing through the point (4, -2) that is parallel to the line - 3x – 4y = 5.
Answers
Answer:
Step-by-step explanation:
Let's solve for x.
−3x−4y=5
Step 1: Add 4y to both sides.
−3x−4y+4y=5+4y
−3x=4y+5
Step 2: Divide both sides by -3.

So, the line is parallel to - 3x - 4y = 5 and the line passes through the point (4, -2).
So, what I did was I pulled up a graphing site on my Chromebook called DESMOS, maybe you could use this in the future to help you out a little bit.
I then graphed the line of - 3x - 4y = 5 or you could simplify it to y = -3/4x + 5/4 .
The slope of the line is 3/4 . You can find this by taking the points (-15, 10) and (5, -5) and doing this...
m = y2 - y1 divided by x2 - x1 which would look like -5 - 10 divided by 5 - -15 which would simplify to -15 over 20 which would get you a slope of -3/4.
Then you take the formula y - y1 = m( x - x1) and substitute in your variables.
It should look something like this y + 2 = - 3/4 ( x - 4) .
This answer is parallel to -3x - 4y = 5.
I’m sorry, I’m not very good at explaining, but I hope this helps you out.

Everything needs to add up to 180. So you have 90 and 20 you will add them and you’ll get 110. Since you want to find the missing measurement you will subtract 180-110 and you’ll get 70. The missing angle is 70. To check: 90+20+70=180
The ratio of Braydon's number of laps he ran to the time he ran is 6:2. The ratio of Monique's number of laps she ran to the time she ran is 104. Explain why these ratios are not in a proportional relationship.
Answers
Answer:
They are not in a proportional relationship because Monique's number and time isnt a proportion. Instead it is a whole number. Like Braydon's his is 6:2 that is the correct way to write it.
Step-by-step explanation:
The ratio is not proportion.
What is ratio and proportion?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other.
Given:
The ratio of Braydon's number of laps he ran to the time he ran is 6:2.
The ratio of Monique's number of laps she ran to the time she ran is 10:4.
The simplest for Braydon is = 6/2 = 3/1
and, the simplest form for Monique = 10/4 = 5/2
As, 3/1 ≠ 5/2
So, the ratio is not proportion.

Answers
Answer:
The answer is $1,875
Step-by-step explanation:
1. I just divided $60,000 by 2 and $1,500 by 2 and got $30,000:$750
2. I realized I needed to do more so I divided again and got $15,000:$375. Next I added it to the question $60,000 + $15,000 = $75,000
3. So then $1,500 + $375 = $1,875

determine the vertex of y=4(x-25)2+ 91
Answers
Answer:
(25, 91)Step-by-step explanation:
y = a(x - h)² + k ← vertex form of the equation of the parabola with vertex (h, k)
So y = 4(x - 25)² + 91 means:
a = 4
x - 25 = x - h ⇒ - 25 = - h ⇒ h = 25
+ 91 = + k ⇒ k = 91
Therefore vertex is:

4. John is packing books into boxes. Each box can hold either 15 small books or 8
large books. He needs to pack at least 35 boxes and at least 350 books, Write a
system of linear inequalities to represent the situation
Answers
Answer:
Your system of inequalities is:
x + y ≥ 35
15x + 8y ≥ 350
Step-by-step explanation:
Let x = number of boxes of small books and let y = number of boxes of large books.
Since John needs to pack at least 35 boxes:
(number of boxes of small books) + (number of boxes of large books) (is at least) 35
x + y ≥ 35
Since John needs to pack at least 350 books:
(number of small books packed) + (number of large books packed) (is at least) 350
(number of small books per box)(number of boxes of small books) + (number of large books per box)(number of boxes of small books) ≥ 350
15x + 8y ≥ 350

y=x2+24x-15
Answers
Answer:
The vertex form of y = x² + 24x - 15 is y = (x + 12)² - 159
Step-by-step explanation:
The vertex form of the quadratic equation y = ax² + bx + c is
y = a(x - h)² + k, where
a is the coefficient of x²(h, k) are the coordinates of the vertex pointh = [tex]\frac{-b}{2a}[/tex] , where b is the coefficient of xk = y at x = hLet us use the facts above to solve the question
∵ y = x² + 24x - 15
∵ a is the coefficient of x² and b is the coefficient of x
∴ a = 1 and b = 24
∵ h is the x-coordinate of the vertex point
∵ h = [tex]\frac{-b}{2a}[/tex]
→ Substitute the values of a and b to find h
∴ h = [tex]\frac{-24}{2(1)}=\frac{-24}{2}[/tex]
∴ h = -12
→ To find k substitute y by k and x by h
∵ y = k and x = h
∴ k = (-12)² + 24(-12) - 15 = 144 - 288 - 15
∴ k = -159
∴ The coordinates of the vertex point are (-12, -159)
→ Substitute the values of a, h, and k in the vertex form above
∵ y = 1(x - -12)² + (-159)
→ Remember (-)(-) = (+) and (+)(-) = (-)
∴ y = (x + 12)² - 159
∴ The vertex form of y = x² + 24x - 15 is y = (x + 12)² - 159
