Tom has a scale model of his car. The scale factor is 12. If the actual car has 16-inch wheels, what size are the wheels on the scale model?
Answer:The scale is 1:12, and the actual car has 16-in wheels.
Step-by-step explanation:
So the setup would be a proportion:
1 over 12=x over 16
Then cross-multiply
12x=16
Divide by 12
X=16/12
=4/3 or 1 and 1/3 in. wheels on the model car.
Use the picture where it says a, b, c, d those are the steps
Step-by-step explanation:
Direction: Opens down
Focus: ( 0,-0.1)
Axis of Symmerty: X=0
Directix: y=0.1
Type [tex]y=-2.5xx^{2}[/tex] on a algebra calcator and it will show you the graph and the eqaution.

Tyra solved the quadratic equation x2-10x -24 = 0by factoring. Her work is shown below:
Step 1: x2-10x -24 = 0
Step 2: x2-4x - 6x - 24 = 0
Step 3: (x2-4x) + (-6x - 24) = 0
Step 4: x(x-4) - 6(x - 4)=0
Step 5: (x-4)(x-6)=0
Step 6: x-4 = 0, x-6 = 0
Step 7: x=4 or x = 6
Step 8: 4, 6
Tyra did not find the correct solutions. Investigate the steps, decipher her mistakes, and explain how to correct Tyra’s work.
Answer:
Step 5 was not correct
Step-by-step explanation:
Tyra cannot take x and 6 common and then remove those valuse.

Answer:
9. x = 7
10. x = 12
Step-by-step explanation:
Assume the two lines are parallel.
9. The corresponding angles are congruent.
9x - 3 = 7x + 11
2x = 14
x = 7
10. The alternate interior angles are congruent.
5x - 20 = 2x + 16
3x = 36
x = 12

Given the function f(x)=(x+3)2-1, which of the following would describe a shift of the vertex 3 units to the left.
A. f(x + 3)
B. f(x)+3
C. f(x)-3
D. f(x-3)
Answer:
A. f(x+3)
Step-by-step explanation:
The vertex form is y=a(x-h)^2+k. To move left, your 'h' value has to be negative, so in this case, it'd be -3, but wait. Since it already tells you to subtract the 'h' value, subtracting -3, (-(-3), would be the same as adding 3. So inside the form, it has to be (x+3) to make sense. A is the correct answer.
B is incorrect because that just shifts the function 3 units up.
C is incorrect because that shifts the function 3 units down.
D is incorrect because that shifts the function 3 units right.
Hope this helps.

If f(x) = 42 - 5 and g(x) = 3x+ 7, which of the following statements are true?
I f(0) = g(-4)
II f(-2) - 9(2)
III f(0) = g(3)
IV f(6) - g(4)
Α. I only
B. I and IV only
C. II and III only
D. All are true
Answer:
B. I and IV only
Step-by-step explanation:
You replace the x with the numbers in the parenthesis. So for I it would be:
f(0) = 4(0) - 5 -> 0 - (-5) -> -5
g(-4) = 3(-4) +7 -> -12 + 7 -> -5
You solve each one and if your answer matches with each other, your answer is right.
If you did this with II and III, you wouldn't get the same answers.
For IV it would be:
f(6) = 4(6) - 5 -> 24 - 5 -> 19
g(4) = 3(4) + 7 -> 12 + 7 -> 19
