Answer:
B. 40 percent
Step-by-step explanation:
First take the new price minus the original price
175-125
50
Divide by the original price
50/125
.4
Multiply by 100%
.4 *100% = 40%
2. What is the equation of the line that passes
through the point (4. – 5) and has slope
Answer:
D. y = 1/2x - 7
Step-by-step explanation:
y = 1/2x + b
-5 = 1/2(4) + b
-5 = 2 + b
-7 = b

(Help fast plz!)Which statement is true regarding the graphed functions
Given:
The graphs of two functions f(x) and g(x).
To find:
The correct statement about the functions.
Solution:
In the given graph blue line represents the graph of f(x) and the red line represents the graph of g(x).
From the given graphs it is clear that the graphs of the functions interest each other at point (-2,4). It means,
[tex]f(-2)=4[/tex]
[tex]g(-2)=4[/tex]
So, we conclude that
[tex]f(-2)=g(-2)[/tex]
Thus the option D is correct.
We can check other options.
[tex]f(4)=-14[/tex]
[tex]g(4)=10[/tex]
[tex]f(4)\neq g(4)[/tex]
So, option A is incorrect.
[tex]g(-2)=4[/tex]
[tex]f(4)\neq g(-2)[/tex]
So, option B is incorrect.
[tex]f(2)=-8[/tex]
[tex]f(2)\neq g(-2)[/tex]
So, option C is incorrect.
Therefore, the correct option is D.

Kelli buys a new backpack for $35. There is a 20% discount and a 7% tax. What will be the final cost of the backpack?
Answer:
29.96
Step-by-step explanation:
First find the discount
35 * 20 %
35*.2
7
Subtract the discount from the price
35-7
28
Now find the tax on the new price
28* 7%
28 *.07
1.96
Add the tax to the new price
28+1.96
29.96

What of the angle is the vertex?
Answer:
Vertex: The common end point at which the two rays meet to form an angle is called the vertex. Here, the point O is the vertex of ∠AOB. We can find angles in various things around us, such as in a pair of scissors, a hockey stick, a chair.
A triangle has side lengths of (5.5x + 6.2y) cm, (4.3x + 8.3z) cm, and (1.6z - 5.1y) cm. Which expression represents the perimeter, in centimeters, of the triangle?
Answer:
9.8x+1.1y+9.9z
Step-by-step explanation:
Hi there!
Perimeter = Sum of all sides
[tex]P=(5.5x + 6.2y)+(4.3x + 8.3z)+(1.6z - 5.1y)[/tex]
Open up the parentheses
[tex]P=5.5x+6.2y+4.3x+8.3z+1.6z-5.1y[/tex]
Combine like terms
[tex]P=5.5x+4.3x+6.2y-5.1y+8.3z+1.6z\\P=9.8x+1.1y+9.9z[/tex]
Therefore, the expression 9.8x+1.1y+9.9z (cm) best represents the perimeter of the triangle.

If -10x – 9y = -7 is a true equation, what would be the value of
-30x – 27y?
Answer:
-30x-27y = -21
Step-by-step explanation:
We know that;
-30x-27y = 3(-10x-9y)
Recall, -10x-9y = -7
Thus; -30x-27y = 3(-7) = -21

Answer:
Use the formula SA=2×length×width+2 length× height+2×height×width. With this I believe your answer should be 13.5. Sorry if it's wrong since the answer choices don't line up but thats the only way it makes sense for me.
Eugene has to buy cupcakes for a picnic. He needs to make sure that there are more than 8 cupcakes so each of his friends gets at least one cupcake. If Eugene buys y boxes that each contain 4 cupcakes, which inequality represents this situation?
A.
y < 8
B.
y > 8
C.
4y > 8
D.
4y < 8
Answer:
C
Step-by-step explanation:
4xy=4y
since each friend must get at least a cupcake, 4y must be larger than 8
The Chang family is on their way home from a cross-country road trip. During the trip, the function D(t)=3260−55t can be used to model their distance, in miles, from home after t hours of driving. find D(12) and interpret the meaning in the context of the problem.
Answer:
D(12) = 2,600 miles
It means a distance of 2,600 miles is already traveled from home after 12 hours
Step-by-step explanation:
To find D(12); all we have to do is to substitute the value of 12 for D
We have this as;
D(12) = 3260-55(12)
D(12) = 2,600
In the context of this problem, what this mean is that the distance away from home is 2,600 miles after traveling 12 hours
Jackie is making flower arrangements. She has 2 roses and 4 daisies. If Jackie wants to make all the arrangements identical and have no flowers left over, what is the greatest number of flower arrangements she can make?
help<3
Let's explore possible case scenarios.
---------------------
Case A) Each person gets a rose and a daisy (2 flowers per person)
In this case, Jackie can make 2 such arrangements because she has 2 roses. We have 2 left over daisies.
---------------------
Case B) Each person gets a rose only (1 flower per person)
Only two arrangements are possible for the same reason as case A. In this situation, we have 4 left over daisies.
----------------------
Case C) Each person gets a daisy only (1 flower per person)
We have 4 arrangements possible because we have 4 daisies. The left over flowers are the 2 roses.
-----------------------
Case D) Each person gets 2 roses
Only one such arrangement is possible, so this only applies to one person really. You can say that 2/2 = 1. We have 4 left over daisies in this case.
-----------------------
Case E) Each person gets 2 daisies
Since 4/2 = 2, this means we can make 2 arrangements. There are 2 left over roses.
------------------------
Case F) Each person gets 2 daisies and 1 rose
We can see that 4/2 = 2 and 2/2 = 1, meaning that we can make at most 2 arrangements here. There are no leftovers. In contrast, the other cases do have leftovers of some kind.
------------------------
In short, you can do trial and error to see which case works to fit the conditions your teacher set. Case F is what we go for to have each flower bouquet consist of 2 daisies and 1 rose. We'll get 2 bouquets possible. Notice how cases A through E have at least one left over flower (either of one kind or both types), while case F has no leftovers.

Answer:
d = 6
Step-by-step explanation:
Since the line is horizontal then the distance from B to C is the distance between the x- coordinates.
d = | - 3 - 3 | = | - 6 | = | 6 | = 6
Answer:
option C
Step-by-step explanation:
[tex]distance, d = \sqrt{(x_B- x_C)^2 + (y_B - y_C)^2}[/tex]
[tex]=\sqrt{(-3 -3)^2 + (6 - 6)^2 }\\\\=\sqrt{(-6)^2 + 0 }\\\\=\sqrt{36}\\\\= 6[/tex]
A rectangular prism with a volume of 222 cubic units is filled with cubes with side lengths of \dfrac14
4
1
start fraction, 1, divided by, 4, end fraction unit.
How many \dfrac14
4
1
start fraction, 1, divided by, 4, end fraction unit cubes does it take to fill the prism?
Answer: 128 cubes
Step-by-step explanation:The dimension of the rectangular prism is not given, assumed not important.
Find the volume of 1 cube:
Volume = 1/4 x 1/4 x 1/4
Volume = 1/64 units³
Find the number of cubes that can go into the prism:
Number of cubes = 2 ÷ 1/64
Number of cubes = 128
Use a graph to tell whether the ordered pairs represent a linear function, an exponential
function, or a quadratic function.
(-2, 2), (-1, 5), (0, 3), (1, 1) (2, 3)
Answer: exponential function
Step-by-step explanation:
Graph it.
You will see that the ordered pairs make the shape of a sideways "S."
Linear functions are straight lines and quadratic functions are "U" or upside-down "U" shaped curves. Exponential functions can have multiple curves like including a sideways "S" shape, so it is exponential.

If a+b=13, and ab-40, then find a3+b3
Answer:
[tex]637[/tex]
Step-by-step explanation:
Step 1: Set Up System of Equations
[tex]a + b = 13[/tex]
[tex]ab = 40[/tex]
Solve for a in the first equation
[tex]a = 13 - b[/tex]
Subsitur that in for the 2nd equation
[tex](1 3 - b)(b) = 40[/tex]
[tex] - b {}^{2} + 13b = 40[/tex]
[tex] - {b}^{2} + 13b - 40[/tex]
[tex] - (b - 5)(b - 8)[/tex]
Set each monomial to zero
Think of a number that adds to 13 and multiply to 40.
Th
[tex]b = 5[/tex]
[tex]b = 8[/tex]
So the answer is 5 and 8. Remember factos are interchangeable so a and b can be either 8 or 5.
Cubed both 5 and 8.
[tex]5 {}^{3} + {8}^{3} [/tex]
[tex]125 + 512 = 637[/tex]

Answer:
4
Step-by-step explanation:
put into calculator
The required rounding of the number 8.31 ÷ 1.87 is 4.4.
Given that,
To find the simplified value for 8.31÷1.87.
A recurring Decimal is defined as also named repeating decimal, is a decimal number that only consists of repeating digits after a certain interval after the decimal. For example, 94.642642642..., 213.569569... etc.
Here,
8.31÷1.87 = 4.444
Where 4 is a repeating decimal so the round to 1 decimal point is 4.4
Thus, the required rounding of the number 8.31 ÷ 1.87 is 4.4.
