Select all expressions that are equivalent to −4(x+2)−2x+4
A) −6x−4
B) −4x+2−2x+4
C) −10x
D) −4x-2x−8+4
Answer: A) -6x-4 Hope that helps!
Step-by-step explanation:
1. Expand by distributing terms -4(x+2)-2x+4
-(4x+8)-2x+4
2. Remove parentheses
-4x-8-2x+4
3. Collect like terms
(-4x-2x)+(-8+4) and simplify meaning multiply if you do -4×-2= -6 and if you do -8+4= -4 So, your answer would be -6x-4 never forget the variable that's the letter that I put went the x in it by the way and can you make me Brainliest please thanks and bye!

In order to find the surface area of a 3-dimensional figure, one must find the 2-dimensional area of all of its faces, then add up the values to find the surface area of the entire figure. The given prism is drawn out in the form of a net, thus, it is rather easy to find the area of each face, and add up the area to find the surface area.
The lateral surface area refers to the surface area of a figure, not including the base of the figure. In this case, the base is the largest rectangle: the one with the dimensions of the following length
[tex](12)*(18)[/tex]
Use the following formulas to find the surface area of each face:
Rectangle: [tex](length)(width)[/tex]
[tex](10)(18)=(180)[/tex]
[tex](10)(18)=(180)[/tex]
Triangle:[tex]\frac{(base)(height)}{2}[/tex]
[tex]\frac{(12)(8)}{2}=48[/tex]
[tex]\frac{(12)(8)}{2}=48[/tex]
Add up all of these values to find the total surface area:
[tex](180)+(180)+(48)+(48)=456[/tex]

What is the slope of the line that contains the
points (-6, 1) and (4,4)?
Answer:
3/10
Step-by-step explanation:
y2 - y1 / x2 - x1
4 - 1 / 4 - (-6)
3/ 10
Answer:
Step-by-step explanation:
y1-y2
--------
x1-x2
so
and (x1,y1) and (x2,y2) are those points so plug it in
(1-4)/(-6-4) so that simplifies to -3/-10 so just 3/10 is the slope.

The marginal cost function for manufacturing perfume is given by c(x) = 7x + 28, where x is the product quantity. Find the change in the cost of perfume when the number of units sold changes from 2 to 10.
A.
$56
B.
$57
C.
$62
D.
$67
Answer:
A. $56
Step-by-step explanation:
the change of cost =
[7(10) + 28] - [7(2) + 28] = 98-42=56
Serena, Alyssa and Katie have just finished lunch at the Rainforest Cafe. Their bill came to $38.96. There is an 8% sales tax. The girls have decided to leave a tip of 15% on the total amount of the bill. How much money did the entire bill come to including the tip?
Answer:
About $48.39
Step-by-step explanation:
Sales tax only applies to the bill, not the tip.
Calculate the sales tax:
38.96 × 8%
38.96 × 0.08
3.1168
Round to the nearest cent:
3.12
Add the sales tax to the bill:
38.96 + 3.12
42.08
Calculate the tip based "on the total amount of the bill:"
42.08 × 15%
42.08 × 0.15
6.312
Round to the nearest cent:
6.31
Add the tip to the rest of the bill:
42.08 + 6.31
48.39
To print tickets, a printer charges a $30 setup fee plus $1.05 per ticket. Write an algebraic expression for the cost of t tickets. What is the cost of 300 tickets?
an explanation 2 plz thx
Answer:
Solution given:
we have
setup price =$30
as rate for 1 print tickets =$1.05/tickets
so
for t
t=$30+$1.05*t
is a required expression.
the
cost of 300 tickets:
300 tickets =$30+$1.05*300=$345
$345is the cost of 300 tickets.

Hi,
I cannot see the options but for vertical compression you need to have values of a that are 0<a<1, then the graph will be compressed.
For example, if we have g(x)= 1/2 x^2 will be compressed by factor of 1/2.

4x + 3(2x - 4) = x
Step 2: Solve for x
[Distributive Property] Distribute 3: 4x + 6x - 12 = x[Addition] Combine like terms: 10x - 12 = x[Subtraction Property of Equality] Subtract x on both sides: 9x - 12 = 0[Addition Property of Equality] Add 12 on both sides: 9x = 12[Division Property of Equality] Divide 9 on both sides: x = 4/3Answer:
x = 1.33
Step-by-step explanation:
4x + 3(2x-4) = x
-4x -4x
3(2x-4) = -3x
Distribute 3 to (2x-4)
6x - 12 = -3x
-6x -6x
-12 = -9x
/-9 /-9
1.33 = x
A teacher gives a test in which the average of the test scores is 68 and the standard deviation is 14. Realizing that the test was probably too difficult, the teacher decides to scale the tests by adding 10 points to all scores. What is the mean and standard deviation of the scaled test scores?
Answer:
Mean = 78 ;
Standard deviation = 14
Step-by-step explanation:
Given that:
Mean score = 68
Standard deviation = 14
When a constant value is added to the individual value of a dataset, the new mean value will become the sum of the initial mean value and the constant term added to the values.
Constant Added score = 10
The mean of scaled test score will be:
Mean score + constant added score
68 + 10 = 78
The standard deviation remains unchanged ; Hence, standard deviation = 14

Step-by-step explanation:
Look at image please
When you have two shapes to compare on a coordinate plane, you can determine the scale factor, knowing that the transformation was a dilation. Generate instructions you would give another student to determine the scale factor. If you know the center of dilation is the origin, you can simply divide any non-zero coordinate of the transformed figure by the corresponding coordinate of the original figure to get the scale factor. Sample Response: Locate two corresponding ordered pairs of the two shapes. Calculate how much the pre-image values were multiplied by to obtain the image values. This is your scale factor. You can calculate this by dividing the coordinates of the mage by the corresponding coordinates of the pre-image. Which did you include in your response? Check all that apply. Use corresponding ordered pairs. Divide the coordinates of the image by the pre-image. Determine that the pre-image times the scale factor produces the image.

Answer:
Easiest to pick (0, 0) and (1, 1) probably, then slope is 1.
Step-by-step explanation:
Rise over run for (0, 0) and (1, 1) is rise up 1 and run over 1, so 1/1.
This means slope is 1

Ms.Lawrence buys 8 ounces of smoked salmon at 17.98 per pound how much money did ms.Lawrence spend on smoked salmon
Answer:
$8.99
Step-by-step explanation:
1 pound = 16 ounces
y pound = 8 ounces
[tex]\frac{1}{16} :\frac{y}{8}[/tex]
y · 16 = 1 · 8
16y = 8
16y ÷ 16 = 8 ÷ 16
y = 0.5
0.5 pound = 8 ounces
----------------------------------
1 pound = $17.98
0.5 pound = y
[tex]\frac{1}{17.98} :\frac{0.5}{y}[/tex]
y · 1 = 17.98 · 0.5
y = $8.99

Explain how to calculate the surface area of a composite figure in your own words.
Answer:
tik
Step-by-step explanation:
Answer:
Sample response: First separate the composite into component figures. Then find the surface area of each figure. A two-dimensional net can be used to find the surface area. Add the surface areas of the components. Then, subtract or exclude the areas of the figures that are shared.
Factor and find the zeros of the relation. (18 marks)
(a.) y = 6 x^2 + 5x − 4
(b.) y = 4x^2 – 64
Answer:
(a.)
=(6x^2-3x)+(8x-4)
=3x(2x-1)+4(2x-1)
=(2x-1)(3x+4)
zeros are x=-4/3, x= 1/2
(b.)
=4(x^2-16)
=4(x+4)(x-4)
zeros are x= -4 and x= 4

Ivan draws PQR on the coordinate plane.
What is the perimeter of PQR? Round to the
nearest unit.
Answer:
Perimeter of PQR = 37 units (Approx.)
Step-by-step explanation:
Using graph;
Coordinate of P = (-2 , -4)
Coordinate of Q = (16 , -4)
Coordinate of R = (7 , -7)
Find:
Perimeter of PQR
Computation:
Distance between two point = √(x1 - x2)² + (y1 - y2)²
Distance between PQ = √(-2 - 16)² + (-4 - 4)²
Distance between PQ = 18 unit
Distance between QR = √(16 - 7)² + (-4 + 7)²
Distance between QR = √81 + 9
Distance between QR = 9.48 unit (Approx.)
Distance between RP = √(7 + 2)² + (-7 + 4)²
Distance between RP = √81 + 9
Distance between RP = 9.48 unit (Approx.)
Perimeter of PQR = PQ + QR + RP
Perimeter of PQR = 18 + 9.48 + 9.48
Perimeter of PQR = 36.96
Perimeter of PQR = 37 units (Approx.)
