Compare the graphs of y = f(x) and y = f(-x).
Answer:
it's equal since they are opposites
DO NOT FORGET STAY SAFE AT HOME
Answer:
if y=f(x), then the graph y=f(-x) is a horizontial reflection of the orgional function. This means that the graph will be reflected across the vertical axis

Answer:
The answer is A) The y-intercept of function A is greater than the y-intercept of function B.
Step-by-step explanation:
We can see by graphing function A that the y-intercept (where the graph crosses the y-axis) is (0,3). For function B, we can see that the y-intercept is (0,2). Therefore, we know that 3 is greater than 2, so the y-intercept for function A is greater than that of function B. I'll attach a photo of the first function graphed online.
Hope this helps! Feel free to give me Brainliest if you feel this was helpful. Have a good day and good luck on your assignment! :)
Answer:
A. The y-intercept of function A is greater than the y-intercept of function B.
Step-by-step explanation:
A. y = -5x + 10
B. y = 3x + 2
The y-intercept of function A is greater than the y-intercept of function B.
10 > 2
I got 2 as my y-intercept for B because the y-intercept is where the line intercepts at the y-axis, and that is at point 2.
Hope this helped!

"he residents of a city voted on whether to raise property taxes. The ratio of yes votes to no votes was 4 to 5. If there were 3190 no votes, what was the total number of votes
Answer: 5742
================================================
Work Shown:
x = number of yes votes
(number who said yes)/(number who said no) = 4/5
x/3190 = 4/5
5x = 3190*4 .... cross multiply
5x = 12760
x = 12760/5 ... divide both sides by 5
x = 2552
There were 2552 people who voted yes
The total number of votes is 2552+3190 = 5742

10(c+5)=125
Step 1: Simplify both sides of the equation.
10(c+5)=125
(10)(c)+(10)(5)=125(Distribute)
10c+50=125
Step 2: Subtract 50 from both sides.
10c+50−50=125−50
10c=75
Step 3: Divide both sides by 10.
10c /10 = 75 /10
c = 15 /2

You are going to mow your neighbor's lawn for some extra money. Below is a scale drawing of their lawn, where each square represents 5 feet.
1. Prove which type of quadrilateral this lawn is. Insert the image of your work with the final answer in the box below:
It is a rectangle.
2. What is the perimeter of the real lawn (not the scale drawing)?
3. Your neighbor will either pay you $40 as a flat rate, or they will give you $0.03 for each sq. foot (3 cents per square foot). Which would make you the most money? Show all your work on a paper and insert the image with the final answer here

Answer:
rectangle; parallelogram with 90° angle150 feet$40 flat rateStep-by-step explanation:
1. The slope of AB is ...
mAB = (yB-yA)/(xB-xA) = (4-0)/(6-3) = 4/3
The slope of AD is ...
mAD = (yD-yA)/(xD-xA) = (6-0)/(-5-3) = 6/-8 = -3/4
The product of these slopes is (4/3)(-3/4) = -1, so the segments AB and AD are perpendicular.
The midpoints of AC and BD will be the same if the sum of their coordinates is the same:
A+C = (3, 0) +(-2, 10) = (1, 10)
B+D = (6, 4) +(-5, 6) = (1, 10)
The midpoints of the diagonals of ABCD are the same, so the figure is a parallelogram. One corner angle is 90°, so the parallelogram is a rectangle. The quadrilateral ABCD is a rectangle.
__
2. Using the coordinate differences found in part 1, we know the length AB is the hypotenuse of a 3-4-5 triangle, so is 5 grid squares. Similarly, the length of AD is twice that length, so is 10 grid squares. The perimeter in grid squares is ...
P = 2(L+W) = 2(10+5) = 30 . . . . grid squares
Each grid square represents 5 ft, so the perimeter is ...
(30 squares)(5 ft/square) = 150 ft . . . perimeter
__
3. The rectangle is 5 × 10 grid squares, or 25 × 50 ft. Then its area is ...
A = LW = (50 ft)(25 ft) = 1250 ft²
At $0.03/ft², the payment for mowing would be ...
($0.03/ft²)(1250 ft²) = $37.50
The $40 flat rate would make you the most money.

Which description best compares these graphs of 2 functions?
Answer:
the Y starts with 2 and X has 2 as the second one and they both have zero
Step-by-step explanation:
Answer:
Equations are the best way of comparing
Step-by-step explanation:
Let's find the equation of B function:
m=[tex]\frac{1-2}{2-0}[/tex]=-0.5
b=2 - y-intercept
So, B equation is y=-x+2
Now we see that these graphs have the same y-intercept(b coefficient in equations), but function A falls down faster than function B
Jennie and Claire make lemonade. The ratio of lemon to water in Jennie's lemonade is 2:3 The ratio of lemon water in Claire's lemonade is 3:4. Use proportions to explain which lemonade is stronger
Pleasee help ASAP ❤️
Answer:
Claire's lemonade is stronger
Step-by-step explanation:
Jennie's lemonade
2/2=1
3/2=1.5
Claire's lemonade
3/3=1
4/3=1.334
Jennie's lemonade has more water in the lemonade per lemon, so Claire's is stronger.
I don't know if I used proportions though.
Hope I did this correctly!
Explain why the triangles below are not similar.
(I need help ASAP!! Due tonight at 5)
Answer:
They aren't similar
Step-by-step explanation:
I needed the points
Answer:
they are not similar.
Step-by-step explanation:
for two triangles to be similar, the corresponding angles must be equal and each sides of two triangles must be in proportion which is not the case of above figures. so the triangles are not similar.
Solve the inequality if possible 4(3-2x)>2(6-4x)
Answer:
there is no value for x
Step-by-step explanation:
[tex]4(3-2x)>2(6-4x)\\\\12-8x>12-8x[/tex]
and we have to equal things and one is bigger than the other
so that means that
y > y
contradiction
Final Answer: No Solution
Steps/Reasons/Explanation:
Question: [tex]4(3- 2x) > 2(6- 4x)[/tex]
Step 1: Divide both sides by [tex]2[/tex].
[tex]2(3 - 2x) > 6 - 4x[/tex]
Step 2: Expand.
[tex]6 - 4x > 6 - 4x[/tex]
Step 3: Since [tex]6 - 4x > 6 - 4x[/tex] is false, we have no solution.

Give the equation for each of the following statements.
1. Y varies jointly as R and T.
2. B is directly proportional to the square of A and inversely proportional to the cube of C.
Answer:
Step-by-step explanation:
1. Y varies jointly as R and T
Y = k*R*T
Y = kRT
Where,
k = constant of proportionality
2. B is directly proportional to the square of A and inversely proportional to the cube of C.
B = k(A²) / C³
B = kA²/C³
Where,
k = constant of proportionality

1. IF the function f(x) = 2(x – 3)2 – 4 is shifted vertically three units up and horizontally
2 units to the right to create the function g(x) fill in the blanks to represent this
transformed function.
g(x)= _(x-__)^2 ____
Answer:
I believe it is 2(x-5)²−1
Step-by-step explanation:
The parentheses represent the horizontal shift. (X-__) is a shift to the right. (X+__) is a shift to the left. The last number of the function is the vertical shift. A negative number is shifting down and a post number is shifting up.
So, if the graph shifts up three units, then you add 3 + -4 to get -1. And if the graph shifts right 2 units, then you subtract 2 from -3 to get -5.
