Answer:
g(3) = -8
Step-by-step explanation:
g(3) = -4x + 4 Substitute 3 for X:
g(3) = -4(3) + 4
-4 * 3 = -12
g(3) = -12+4

Graph the image of the figure after a dilation with a scale factor of 3 centered at (2, −7).
Use the Polygon tool to graph the quadrilateral by connecting all its vertices.
Answer:
Step-by-step explanation:
Each point moves 3 times the distance from the center of dilation that it was.
You can compute the new coordinates by ...
L = P - O . . . . . the length from O to P is P-O for some point P and origin O
Then 3 times that distance is
3L = 3P -3O
We want to find the point P' that is 3L from O, so we add this distance to the coordinates of O. We get ...
P' = 3L +O = 3P -3O +O
P' = 3P -2O
So, for the lower left point A(-2, -7), the dilated image point A' is ...
A' = 3(-2, -7) -2(2, -7) = (-6, -21) +(-4, 14) = (-10, -7)
That is, ...
A' = 3A +(-4, 14)
The coordinates of the remaining points can be found similarly.
___
On a graph, it is usually fairly easy to count the grid squares in each direction between the point of interest and the center of dilation. The image point is 3 times the distance in each direction (horizontally, vertically).

The perimeter formula for a rectangle is 2l + 2w, where l is the length and w is the width. A rectangle. The top of the rectangle is labeled (8 x minus 1) inches. The right side is labeled (2 x + 4) inches. Complete the steps to find an expression that represents the perimeter of the rectangle. Substitute the expressions for length and width into the formula 2l + 2w. Distribute 2 to each term in the parentheses. Combine like terms. inches
Answer:
1.) 2(8x-1)+2(2x+4)
2.) 16x-2+4x+8
3.) (20x+6)
Step-by-step explanation:
The perimeter of the rectangle is (20x + 6)inches
The perimeter of a rectangleThe formula for calculating the perimeter of a rectangle is expressed as:
P = 2l + 2w
Given that;
l = 8x - 1
w = 2x + 4
Susbtitute
P = 2(8x - 1) + 2(2x + 4)
Expand
P = 2(8x) - 2(1) + 2(2x) + 2(4)
P = 16x - 2 + 4x + 8
P = 16x + 4x - 2 + 8
P = 20x + 6
Hence the perimeter of the rectangle is (20x + 6)inches

Aliza needs to run at a rate faster than 8.8 feet per second in order to exceed her fastest time in a race. After running for 15 minutes, her coach determines that she is running at an average rate of 5.8 miles per hour. He converts the average rate to feet per second as shown below: He concludes that she is not running fast enough to exceed her fastest time. What errors did the coach make? Check all that apply. He used an incorrect time ratio converting hours to minutes. His units do not cancel. He used an incorrect distance ratio converting miles to feet. He incorrectly concluded that she is not running fast enough. He cannot determine her average rate in miles per hour after only 15 minutes.
Answer:
a. He used an incorrect time ratio converting hours to minutes.
d. He incorrectly concluded that she is not running fast enough.
Step-by-step explanation:
Looking at the Coach's method of conversion when converting time, he assumed that an hour had 15 minutes instead of 60 minutes. He therefore did not use the correct time ratio to convert hours to minutes.
The coach's calculations yielded an answer of 34 ft/s. This is way faster than 8.8 ft/ s so his deduction that she was not running fast enough to beat her fastest time is incorrect because at that inhumane speed, she did.
Answer: A.)He used an incorrect time ratio converting hours to minutes.
D.)He incorrectly concluded that she is not running fast enough.

Luca has a 15% off discount card to use at the frozen yogurt place. If he buys $4.78 of frozen yogurt how much will he pay after the discount? please explain how you got your answer :>
Answer:
4.06 dollars
Step-by-step explanation:
To find the discount, you multiply 4.78 by 0.15. You get 0.717. You round it to get 0.72. You then subtract. 4.78-0.72=4.06.

Answer:
(B). 50°
Step-by-step explanation:
(5x + 55)° = (2x + 100)°
5x + 55 = 2x + 100
5x - 2x = 100 - 55
3x = 45
x = 15
5(15) + 55 = 130°
m∠2 = 180° - 130° = 50°

Find the area of the triangle with A = 60°, b = 11 feet, and c = 8 feet. Round to the nearest tenth.
Answer:
41.25 ft^2
Step-by-step explanation:
Literally all you need to do is Pythagorean Theroem.
a = ?
b = 11ft
c = 8ft
a^2 + b^2 = c^2
a^2 + 11^2 = 8^2
a^2 + 121 = 64
64 - 121 = a^2
a = 7.5
Then area of a triangle formula is (bh)/2
(11 x 7.5)/2 = 41.25

Answer:
We conclude that:
m∠XWY = 41°Step-by-step explanation:
Given
m∠VWX = 139°
m∠YWZ = 23°
To determine
m∠XWY = ?
We know the measure of the angle of a straight is 180°.
As m∠VWX and m∠XWY lie on a straight line.
Thus, the sum of m∠VWX and m∠XWY must be 180°
so we get the equation
m∠VWX + m∠XWY = 180°
Given that m∠VWX = 139°
so substituting m∠VWX = 139° in the equation m∠VWX + m∠XWY = 180°
139° + m∠XWY = 180°
m∠XWY = 180° - 139°
m∠XWY = 41°
Therefore, we conclude that:
m∠XWY = 41°HELP ASAP ILL MARK YOU BRAINLIST IF YOU ACTUALLY HELP!!!

In triangle QRS the measurement of an angle RSQ is 29.1 and the measure of angle QRS is 70 degrees what is the measurement of sqr
Answer: The measure of ∠SQR= 80.9°
Step-by-step explanation:
Given: In triangle QRS,
∠ RSQ = 29.1° and ∠QRS=70°
To find: ∠SQR
Angles sum property of triangle = Sum of all the angles in a triangle is 180°.
For Δ QRS,
∠SQR + ∠ RSQ +∠QRS = 180°
⇒ ∠SQR + 29.1° + 70° = 180°
⇒ ∠SQR + 99.1° = 180°
⇒ ∠SQR= 180°-99.1
⇒ ∠SQR= 80.9°
Hence, the measure of ∠SQR= 80.9°
