Answer:
a = 2
Step-by-step explanation:
4 (2a + 3) = 28
4 * 2
= 8
4 * 3
= 12
8a + 12 = 28
28 - 12
= 16
8a = 16
16 / 8
= 2
a = 2
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

Step-by-step explanation:
First of all, we should have a number in the tenths place, and we don't.
Also, in the hundredths place, we should have 9, not 4.
And finally, the answers should be 0.195, not 0.042.
Answer:
This is False
You want to add it up as if there wasnt any decimal than you want to put the decimals back 3 spots
0.025 + 0.17= 0.195

Step-by-step explanation:
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.

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.

Identify the x- and y-intercept and graph the equation on the coordinate plane to the left. What is the y-value when x is 2? Answer these questions in the text box below.
Answer:
x int is (6,0). y int is (0,4) and y value when x is 2 is 8/3
Step-by-step explanation:
to solve these questions, we can simply plug everything in. The x intercept for Example, is where the y is equal to 0. So we can plug in 0 for y to get the x int, and vice versa for the y int. To find out the y value when x is two, plug in x as two
2 times 2 +3y=12
3y=8
y=8/3
Which equation represents the relationship between x and y in the table?
A. y = x2
B. y=x6
c. y = 4x - 3
