Answer:
12x² + 6xy - 30x
Step-by-step explanation:
Given expression,
→ 6x(2x + y - 5)
Simplifying the given expression,
→ 6x(2x + y - 5)
→ (6x × 2x) + (6x × y) - (6x × 5)
→ 12x² + 6xy - 30x
Thus, answer is 12x² + 6xy - 30x.
-2(v + 1) + 5v = 3(v + 1) - 2
Answer: no solution
Step-by-step explanation:
distributing we have
(-2v-2) + 5v = (3v+3)-2
which will be equal to
3v -2 = 3v + 1
subtracting 3v we have
-2 = 1 which is false so no solution

The graph of the function is graph (a) and the table of values of the function f(x) = (3/4)ˣ is
x -2 -1 0 1 2
y 16/9 4/3 1 3/4 9/16
How to make the table of values of the functionFrom the question, we have the following equation that can be used in our computation:
f(x) = (3/4)ˣ
The x values on the table of values are
x = -2, -1, 0, 1 and 2
So, we replace x in the function f(x) = (3/4)ˣ with x = -2, -1, 0, 1 and 2
So, we have
f(-2) = (3/4)⁻² = 16/9
f(-1) = (3/4)⁻¹ = 4/3
f(0) = (3/4)⁰ = 1
f(1) = (3/4)¹ = 3/4
f(2) = (3/4)² = 9/16
This implies that
The table of values is
x -2 -1 0 1 2
y 16/9 4/3 1 3/4 9/16
When this is represented on a graph, it crosses the y-axis at (0, 1)
This is represented by graph (a)
Hence, the graph of the function is graph (a)

The graph △ABC and its image is A′(2, 4), B′(-2, -2), C′(4, −2).
What is the coordinate rule?
Rules for the coordinate plane: (x, y) Where h and k are the horizontal and vertical shifts, respectively, we have (x ± h, y ± k).
Here, we have
The coordinate rule for dilation with k = 2 to find the coordinates of the vertices of the image.
(x, y) → (2x, 2y)
A(2, 1) → A′(2, 4)
B(4, 1) → B′(-2, -2)
C(4, −1) → C′(4, −2)
Each side length of △A′B′C′ is longer than its corresponding side by the scale factor. The corresponding sides are parallel because their slopes are the same.
Hence, after a dilation centered at the given point using the given scale factor the image is A′(2, 4), B′(-2, -2), C′(4, −2).

The amount that is closest to Nathan's total costs after the 15% discount and including 6% sales tax, assuming tax is applied after the discount is applied would be $624. That is option A.
What is discount on sales?The discount on sales is the amount of money that is being deducted from the original price of an item by a seller to their customers.
The original price for labor= $299.88
The original price for parts = $ 307.54
The original price for others = $ 74.71
The total original price = $682.13
The discount of on the total price = 15%.
That is;
= 15/100 × 682.13
= 10,232.95/100
= $102.32
When discount is removed from the original price;
= 682.13 - 102.32
= $579.81
When the tax is acted on the discount total sales;
= 6/100 × 579.81
= $3,478.86/100
= $34.79.
The total cost after discount and tax would be;

20 m longer it is to walk from A to B along the diagonal of the walk than to walk along the edges of the park.
Given:
Assume ABCD is a rectangular park of right triangles ABC of length = 40m, width = 30m, ∠C = 90
In the right-angled triangle ABC,
By Pythagoras' theorem,
AB² = AC² + BC²
AB² = 30² + 40²
AB² = 900 + 1600
AB² = 2500
AB² = [tex]\sqrt{2500}[/tex]
AB = 50m
The distance from A to B along the diagonal of the park = 50m
The distance from A through to C = 30m.
The distance from A through C to B = 30 + 40 = 70m.

The cost of running the ad for three weeks by Enrique will be $207.
To estimate the overall cost for three weeks, we need the amount for one week. Further, we need the cost for six lines advertisement. So, performing calculation for the cost of advertisement of six lines in one week.
Total cost in one week = charge for first two lines + number of additional lines × cost of each additional line
Keep the values in formula. Out of six lines, the additional will be 4 as (6-2=4).
Total cost in one week = 42 + 4×6.75
Performing multiplication
Total cost in one week = 42 + 27
Performing addition
Total cost in one week = $69
Cost for three weeks = 69×3
Performing multiplication
Cost for three weeks = $207
Thus, Enrique will pay $207 for three weeks.

WRITE THE EQUATION IN
SLOPE-INTERCEPT FORM
(1,-5) and (-2,-17)
Answer:
f(x) = 4x -9
Step-by-step explanation:
The slope-intercept form is f(x) = mx + b, where m is the slope and b is the y-intercept.
First, we need to find the slope, m.
= [tex]\frac{-5-(-17)}{1-(-2)}[/tex]
= [tex]\frac{12}{3}[/tex]
= [tex]4[/tex]
m = 4, and now we plug it into the equation, using any given point, (1,-5) in this case.
f(x) = 4x + b
(-5) = 4(1) + b
-5 = 4 + b
b = -9
Now we find the equation: f(x) = 4x -9, and if we plug (-2,-17) in, we should get the same number as if we plug in (1,-5).
3) Which equation correctly matches the graph below?

through: (-4, 3), perp. to y = -2x+5
Answer:
y = [tex]\frac{1}{2}[/tex] x + 5
Step-by-step explanation:
Perp means perpendicular?
Perpendicular slopes are the opposite reciprocals of each other. So the slope would be [tex]\frac{1}{2}[/tex]
Use -4 for x and 3 for y and the slope of [tex]\frac{1}{2}[/tex] to find the y intercept
y=mx +b
3 = [tex]\frac{1}{2}[/tex](-4) + b
3 = -2 + b Add 2 to both sides
5 = b
y = mx +b We know the slope (m) is [tex]\frac{1}{2}[/tex] and the y intercept (b) is 5.
y=mx+ b
y = [tex]\frac{1}{2}[/tex] x + 5

Two cars leave at the same time but travel at different speeds. Car a travels 20 miles per hour faster than car b. In the time it takes car a to travel 350 miles, car b travels 250 miles.
The number of hours needed for Car B to overtake Car A is greater then 5 hours, Car A = 60km/h; Car B= 75km/h.
After h hours, the number of kilometers covered by Car A is 60*h
After h hours, the number of kilometers covered by Car B is 75(h-1)… since Car B started one hour later.
For Car B to overtake Car A,
75(h-1) > 60h

a cone-shaped paper drinking cup is to be made to hold 27cm3 of water. find the height and radius of the cup that will use the smallest amount of paper.
The height and radius of the cone-shaped cup that will use the smallest amount of paper, that is the maximum volume is 3.72 and 2.632 respectively.
Formula used in the solution is
Volume of the cone= (1/3)π(r^2)h
Area of the cone= πr√(l^2 + r^2)
Given, the volume of the cone is 27 cm^3.
(1/3)π(r^2)h =27
Simplifying the equation to get the value of r.
π(r^2)=81/h
r^2=81/hπ
[tex]r=\sqrt{\frac{81}{\pi h} }[/tex]
Substituting the value of r in area, we get
[tex]A=\pi \sqrt{\frac{81}{\pi h} } \sqrt{h^{2} + \frac{81}{\pi h} }[/tex]
[tex]\frac{dA}{dh} =\pi \sqrt{\frac{81}{\pi h} } \sqrt{h^{2} + \frac{81}{\pi h} }[/tex]
dA/dh=√81 × (π - 162/[tex]h^{3}[/tex]) × 1/√(πh + 81/[tex]h^{2}[/tex])
At dA/dh=0, we will get,
√81 × (π - 162/[tex]h^{3}[/tex]) × 1/√(πh + 81/[tex]h^{2}[/tex])=0
√81 × (π - 162/[tex]h^{3}[/tex])=0
[tex]\pi - \frac{162}{h^{3} }=0[/tex]
Thus, [tex]\pi h^{3} -162=0[/tex]
[tex]\pi h^{3} =162[/tex]
[tex]h^{3} =\frac{162}{\pi}[/tex]
h^3= 51.5662015618
h= 3.7221
Now, substitute h in radius,
[tex]r=\sqrt{\frac{81}{\pi \times 3.7221} }[/tex]
r=2.632
