13=2f+5
What does f =

Answers

Answer 1

Answer:

4

Step-by-step explanation:

Step 1:

13 = 2f + 5         Equation

Step 2:

8 = 2f      Subtract 5 on both sides

Step 3:

f = 8 ÷ 2     Divide

Answer:

f = 4

Hope This Helps :)

Answer 2

Answer:

I did this before! heres what i did: 13=2f+5

We simplify the equation to the form, which is simple to understand  

13=2f+5

We move all terms containing f to the left and all other terms to the right.  

-2f=+5-13

We simplify left and right side of the equation.  

-2f=-8

We divide both sides of the equation by -02 to get f.  

f=4

Step-by-step Answer:

Whenever we have a problem like this, we can have 2 solutions (either one can work) because, in absolute equations, we need to find how far away the number is from 0.

So the answer would simply be that a>2 and a<-2

a can be anything greater than 2 or a can be anything less than 2

Suppose the cost of producing tires, t, is defined by C(t) = -0.45+2 + 12+ 450. Determine
which of the following intervals has the greatest average rate of change for the cost to
produce tires.
A
Between 2 and 4 tires
B
Between 46 and 48 tires
C
Between 12 and 14 tires
D
Between 22 and 24 tires

Answers

Answer:

Option (A)

Step-by-step explanation:

Function to represent the cost of producing 't' tires is,

C(t) = -0.45t² + 12t + 450

Since average rate of change of the function in the interval (a, b) is given by,

Average rate of change = [tex]\frac{f(b)-f(a)}{b-a}[/tex]

Following this rule,

Average rate of change in the interval (2, 4)

= [tex]\frac{C(4)-C(2)}{4-2}[/tex]

= [tex]\frac{490.8-472.2}{4-2}[/tex]

= 9.3

Average rate of change in the interval (46, 48)

= [tex]\frac{-10.8-49.8}{2}[/tex]

= -30.3

Average rate of change in the interval (12, 14)

= [tex]\frac{529.8-529.2}{2}[/tex]

= 0.3

Average rate of change in the interval (22, 24)

= [tex]\frac{478.8-496.2}{24-22}[/tex]

= --8.7

Average rate of change is greatest in the interval (2, 4)

Option (A) will be the answer.

Answer:

Average rate of change is greatest in the interval (46. 48)

Step-by-step explanation:

Average rate of change in the interval (2, 4)

= 9.3

Average rate of change in the interval (46, 48)

= -30.3

Average rate of change in the interval (12, 14)

= 0.3

Average rate of change in the interval (22, 24)

= --8.7

The graph of the parent function f(x) = x3 is translated to form g(x) = (x – 7)3 + 9. The point (0, 0) on the graph of f(x) corresponds to which point on the graph of g(x)?

(7, 9)
(–7, 9)
(9, 7)
(9, –7)

Answers

Answer:

c

Step-by-step explanation:

Using translation concepts, it is found that the point (0, 0) on the graph of f(x) corresponds to point (7, 9) on g(x).

What is a translation?

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

here, we have,

Considering the translations, the equivalent point is found as follows:

x -7 = 0 -> x =7.

y = 0 +9-> y = 9.

Hence the point (0, 0) on the graph of f(x) corresponds to point (7,9) on g(x).

EXPLAIN HOW YOU GOT 3 AND 4 WITH STEPS PLS ITS URGENT

Answers

Answer:

2. x=25°

3. x=15°

4. x=26°

Step-by-step explanation:

For problem 2, we know the sum of the angles of a triangle is 180°. Also, supplementary angles are 180°.

30+20+x=180                  [combine like terms]

50+x=180                         [subtract both sides by 50]

x=130

Now that we have the missing angle, we can use that to solve for x.

2x+130=180                     [subtract both sides by 130]

2x=50                               [divide both sides by 2]

x=25°

Now, we know that x=25°.

For problem 3, we know the sum of the angles of a triangle is 180°. This means, we add all the angles together and get 180°.

8x+25+2x+5=180            [combine like terms]

10x+30=180                     [subtract both sides by 30]

10x=150                            [divide both sides by 10]

x=15°

Now, we know that x=15°.

For problem 4, we know the sum of the angles of a triangle is 180°. This means, we add all the angles together and get 180°.

x+12+52+90=180             [combine like terms]

x+154=180                        [subtract both sides by 154]

x=26°

Now, we know that x=26°.

Answer:

3. x = 5        4. x = 26

Step-by-step explanation:

3.

(2x + 5)  + 8x + 25 = 180

10x +30 = 180

10x = 150

x = 15

4.

52 + 90 + x+12 = 180

52 + 90 + 12 = 142

x + 142 = 180

x = 180 - 154

x = 26

To write an equation in slope-intercept form, given a graph of that equation, pick two points on the line and use them to find the slope. This is the value of m in the equation. Next, find the coordinates of the y-intercept--this should be of the form (0, b). The y- coordinate is the value of b in the equation.
