Answer:
1. Center of rotation is (0,0), the origin. And you can label the green triangle's points PQR. it doesn't matter where you start just put P, Q, & R on each points of the green triangle
2. Reflection line is y = 0. And you can label the red triangle's points XYZ. it doesn't matter where you start just put X, Y, & Z on each points of the red triangle

Find the solution to the system of equations
Answer:
x=1
y=-4
Step-by-step explanation:
Since -x-3=y subsitue that in at the top equation
[tex] - x - 3 = - 7x + 3[/tex]
[tex] - x = - 7x + 6[/tex]
[tex]6x = 6[/tex]
[tex]x = 1[/tex]
Plug x=1 back into the equation to solve for y.
[tex]y = - 7(1) + 3[/tex]
[tex]y = - 4[/tex]

When eating out, it is customary to tip your server at least 15% of the cost of your meal. The graph shows a 15% tip, t, for a meal that costs m dollars.
Each of the following sets of numbers represents dollars. Assuming the graph is correct, which set of numbers is most appropriate to label the seven tick marks along the vertical axis (15% tip)?
Question 5 options:
15, 30, 45, 60, 75, 90, 105
1.50, 3, 4.50, 6, 7.50, 9, 10.50
5, 10, 15, 20, 25, 30, 35
10, 20, 30, 40, 50, 60, 70
Answer:
1.50, 3, 4.50, 6, 7.50, 9, 10.50
Step-by-step explanation:
The x axis represents the amount of money the meal (without tip) costs.
The question is asking what numbers should label the tick marks on the y-axis given that we are assuming a 15% tip.
So the question is really easy to solve. We see our first point is at (1,1) on the coordinate plane which has the meal costing $10. All you have to do to find the tip is to multiply $10 x (0.15%) = 1.50...
So 1.50 should label the first tick mark on the y-axis. You can do the same for all of the numbers. But only one answer choice gives 1.50 as an option, so answer choice 'C' is correct!
Hope this helps, let me know if you need further or better explanations!
The set of numbers is most appropriate to label the seven tick marks along the vertical axis 1.50, 3, 4.50, 6, 7.50, 9, 10.50. The correct option is B.
What is graphical representation?The term "graphical representation" refers to the use of charts and graphs to visually display, understand, and explain numerical data, functions, and relationships.
The x-axis represents the amount of money the meal (without tip) costs. The question is asking what numbers should label the tick marks on the y-axis given that we are assuming a 15% tip.

Then 1.50 should label the first tick mark on the y-axis. You can do the same for all of the numbers. But only one answer choice gives 1.50 as an option, so answer choice 'C' is correct.
Therefore, the set of numbers is most appropriate to label the seven tick marks along the vertical axis 1.50, 3, 4.50, 6, 7.50, 9, 10.50. The correct option is B.

this is the correct answer
Answer:
x=5
Step-by-step explanation:
First you subtract the 5 from both sides, so it'd be 4x=20. Then you divide 4 from both sides making it x=5

Please solve this for me
Answer:
A) 75 levels
B) Level 35
Step-by-step explanation:
A) 37 - (10 - 3) = 37 - 7 = 30
[tex]\frac{2}{5}[/tex] = [tex]\frac{30}{x}[/tex]
2x = 150
x = 75
B) Gym = 37 + 3 = 40
12[tex]\frac{1}{2}[/tex]% = 12.5% = 0.125
40 x 0.125 = 5
40 - 5 = 35
Your friend drew the diagram to prove to you that two planes can intersect in exactly one point. Describe your friend's error. How do you describe a plane? What does it mean for two planes to intersect each other and what are possible intersections of two planes? Can you define an endpoint of a plane?
Step-by-step explanation:
If two planes intersect, they intersect in a line. The line and the plane intersect in a single point. The line and the plane do not interesect. In this case they are called parallel.
What is the equation for the line in slope-intercept form? Enter your answer in the box.
Answer: y=8x
Step-by-step explanation:
Slope-intercept form is y=mx+b, where m is slope and b is y-intercept. To find slope, we take any two points and plug them into [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]. Let's use (1,8) and (2,16).
[tex]m=\frac{16-8}{2-1}=\frac{8}{1} =8[/tex]
Now, we know that m=8. Looking at the graph, we can see that the y-intercept is b=0 because the line passes through the y-axis at (0,0). To be sure, let's plug in a point into our equation to see if the y-intercept is correct.
y=8x+b [plug in (1,8)]
8=8(1)+b [multiply]
8=8+b [subtract both sides by 8]
b=0
Therefore, our equation is y=8x.

Answer:
A = -8
B = 27
X = 6
y = 3
z = 9
Step-by-step explanation:
hope that helps
Answer:
Below in bold.
Step-by-step explanation:
A = (-2)^3 = -8.
B = (3)^3 = 27.
j^(3*3) = j^9 and j^(1*3) = j^3
j^9 / j^3 = j^6
So x = 6.
y = 3.
m^(3 * 3) = m^9.
z = 3*3 = 9.

7. In the diagram below, AB = CD. Find the length of AD.
2x+8
X-3
4x-6
A
B
C
D
Answer:
AD=6
Step-by-step explanation:
If AB=CD then 2x+8=4x+6, this can be rearranged to get 8-6=4x-2x or 2=2x or x=1.
AD=AB+BC+CD or AD=(2x+8)+(x-3)+(4x-6) this can be rearranged as AD=(2x+x+4x)+(8-3-6) or AD=7x-1 and we know x=1 so AD=6.
