Answer:
f(2) = -2
Step-by-step explanation:
f(2) = 2x - 6
f(2) = 2(2) - 6
f(2) = 4 - 6
f(2) = -2
Write the Linear Equation in Point-Slope Form for a line that has a slope of
-10 and passes through the point (8,2). *
Answer:
y = -10x + 82
Step-by-step explanation:
Plug in the slope and point into y = mx + b to solve for b:
y = mx + b
2 = -10(8) + b
2 = -80 + b
82 = b
Then, plug b and the slope into y = mx + b
y = -10x + 82 is the equation in point slope form.
Need help with this problem
Answer:
Step-by-step explanation:
2x + 1 + x + 23 = 180
3x + 24 = 180
3x = 156
x = 52
2(52) + 1 = 104 + 1 = 105
52 + 23 = 75
11. Point A(-2,9) is rotated 180 degrees what is the value of A'? *
A (-9,-2)
A'(-2,-9)
A (9,2)
A(-9,2)
O A' (2,-9)
HELPPP QUICK
It should be (2, -9). When rotating 180° you always make the x and y the opposite, so you take the opposite of -2 and the opposite of 9 to get (-2, 9). Hope this helps!

Step-by-step explanation:
Find the slope of the line passing through the points (-18, -5) and (-19, -13)
Answer:
Let (-18, -5) be (x1,y1)
(-19, -13) be (x2,y2)
slope = (y2-y1)/(x2-x1)= (-13+5)/(-19 +18) = 8
Answer: The slope is 8.
Step-by-step explanation: To get the slope you have to do y2 - y1 over x2 - x1. so you take the -5 and subtract -13 from it, which equals 8. Then subtract -19 from -18 which is 1. So you have 8/1 which is 8.
10% of £26 is equal to x% of £52. Calculate the value of x.

My favorite group, The Lumineers, is coming to Prescott and YC for a concert. Tickets are sold in three levels, $45, $65, and $95 depending on seats. The auditorium seats 1100 people total on the different levels; for them to come to YC we need to sell $66,500 worth of tickets and the auditorium has as many cheap ($45) tickets as the sum of the other two levels ($65 and $95).
Answer:
550 $45 tickets, so $24750 worth of $45 tickets
Step-by-step explanation:
If $45 tickets=x, $65=y, and $95=z, then the question is saying x=y+z. And if x+y+z=1,100, then x=1100/2, so 550 $45 tickets. 550*45 is $24750

What is the answer to -2r-4r=0
Answer:
r = 0
Step-by-step explanation:
First, combine like terms:
(-2r - 4r) = 0
(-6r) = 0
Isolate the variable, r. Divide - 6 from both sides:
(-6r)/-6 = (0)/-6
r = 0/-6 = 0
r = 0 is your answer.

Explain why Figure B is not the image of Figure A after a rotation using center P
Answer:
because the are not the same measurement nor the right placement
Step-by-step explanation:
The sides of figure B appear narrower than the sides of figure A.
We need to explain why Figure B is not the image of Figure A after a rotation using centre P.
What is a rotation?A rotation is a type of transformation that takes each point in a figure and rotates it a certain number of degrees around a given point.
Now,
The reason why figure B is not the image of figure A after a rotation using centre P includes
1) The angle of rotation is measured as 180 - 45 = 135°, while the angle of rotation of the base is (90 - 26) + (90 - 71) = 83°
2) Rotation of a figure is a rigid transformation, such that the dimensions of the sides of the pre-image and the sides of the image should be equal after the rotation, however, the sides of figure B appear narrower than the sides of figure A.
Therefore, the sides of figure B appear narrower than the sides of figure A.

The scale is 1:500 the students cell model has a length of 15 Cm.
How many cm is the real cells length
A. 33cm
B. 0.002
C. 0.03
D. 7500 cm
Answer:
Option C - 0.03 cm
Step-by-step explanation:
The model has a length of 15 cm.
Now, we are told that the scale is 1:500. This means that 1 unit is represents 500 cm on the model.
Since the length on the model is 15 cm which is 15 units, then the true length would be;
15 × 1/500 = 0.03 cm
Therefore, the true length is 0.03 cm.
Option C is correct
Answer:
0.03 cm
Step-by-step explanation:
The length of a rectangle is eight more than twice its width. The perimeter is 88 feet. Find the dimensions of the rectangle.
A w = 10 ft, l = 18 ft
B w = 16 ft, l = 28 ft
C w = 18ft, l = 24 ft
D w = 12 ft, l = 32 ft
Answer:
D w = 12ft, l = 32ft
Explanation:
Make an equation for your length based on the given information.
l = 2w + 8
Make an equation using what you know about the perimeter
p =2l + 2w, p = 88
88 = 2l +2w
Substitute in your previous equation for l.
88 = 2(2w + 8) + 2w
Distribute and simplify.
88 = 4w + 16 + 2w
88 = 6w + 16
72 = 6w
w = 12
Now you can solve for l using the first equation.
l = 2(12) + 8
l = 32
Your answer is w = 12fr, l = 32ft. You can check your work by plugging the values back into the perimeter equation.
simplify and solve
a x= -16
b x = -10
c x=10
d=16
