Graph h(x)=4|x +4|+3

Answer:

3.5 miles

Step-by-step explanation:

From the question, we have the following information:

The super speedway at Daytona International Speedway is = 2.5 miles

long

The road course there is = 1.4 times as long as the super speedway.

How long is the road course?

The length of the road course is calculated as:

1.4 × length of the super speedway

1.4 × 2.5 miles

=>3.5 miles

Therefore, length of the road course I s 3.5 miles.

Answer:

A fraction between that is 2311/3740

Step-by-step explanation:

This is because the denominator is simplified into one number and the fraction is taken from there.

2311/3740

34 = 2×17

55 = 5×11

LCM = 2×5×11×17 = 1870

⁵⁵⁾21/34 = ²⁾1155/1870 = 2310/3740

³⁴⁾34/55 = ²⁾1156/1870 = 2312/3740

2310/3740 < 2311/3740 < 2312/3740

Answer:

The answer is x>17

Step-by-step explanation:

First subtract 4x from both sides

6x - 8 > 4x + 26

-4x. -4x

2x - 8 > 26

8 is negative so to get rid of it add 8 to -8 and 26

2x - 8 > 26

+8. +8

2x > 34

x needs to be by itself so divide both sides by 2

2x > 34

2. 2

x > 17

Answer:

45 miles per hour

Step-by-step explanation:

Mary drove 4 hours to reach her camping spot. Driving home, she increased her speed by 15 miles per hour, reducing her travel time by 1 hour. How fast did she drive going to the camping spot?

d = rt

Where,

d = distance

r = rate of speed

t = time

Going to the camping spot

d=rt

Where, t = 4 hours

d = r × 4

d = 4r (1)

Driving home

She reduced her travel time by 1 hour

That is t = 4 -1 = 3 hours

Then increased speed by 15 miles per hour

That is r = r + 15

d=rt

d = (r+15) × 3

d = 3r + 45 (2)

Equating the two equations

4r = 3r + 45

Collecting like terms

4r - 3r = 45

r = 45

r = 45 miles per hour

check:

d = 4r

d = 45*4

=180 miles

d = 3r + 45

d = 3*45 + 45

= 135 + 45

=180 miles

Answer:

Y=-7

Step-by-step explanation:

The solution to the equation -3y = 21 is y = -7.

To solve the equation -3y = 21 using inverse operations, we want to isolate the variable y by performing the inverse operation.

Now, the inverse operation of multiplication by -3 is division by -3.

By dividing both sides of the equation by -3, we can isolate y.

Let's perform the inverse operation:

(-3y) / -3 = 21 / -3

y = -7

Therefore, the solution to the equation -3y = 21 is y = -7.

Answer:

1/2

Step-by-step explanation:

To make this a equal fraction we have to make the denominator(the bottom) the same

So the fraction would be multiplied by 2 = 10/6

Now we add 10/6 by -7/6

This is the same thing as 10/6 - 7/6 which is 3/6

Now we simplify 3/6. 1/2

5 x 3 =

Step-by-step explanation:

Length times width.

The multiplication equation represented by the model is 5 x 3.

Multiplication is the process of determining the product of two or more numbers in mathematics. A product, or an expression that specifies factors to be multiplied, is what happens when you multiply two numbers in mathematics.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

The model has 5 rows and 3 columns shaded. The multiplication equation will be written below,

Answer:

Step-by-step explanation:

the product of two and a number x is 2•x

so the sum of seven and the product of two and a number x is:

7 + 2x

Step-by-step explanation:

The function is positive when the graph is over the x-axis, and negative when the graph is under the x-axis.

As we can see from the graph, it has x-intercepts at x = -3 and x = 3.

Since the graph curves upwards, the function is positive in intervals (-∞, -3) U (3, ∞) and negative in the interval (-3, 3).

13- A 14-B

Step-by-step explanation:

You take the formula (x1+x2/2, y1+y2/2) and plug in accordingly. For instance, when you plug the values in for 13, you would get:

x1+-9/2, y1+7/2= -8,2

All you have to do from there is a simple guess and check or plug in each number from the multiple answer choices you have. You should then get A (-7,-3) Do the same with 14, in which you should get B (11,-20)

Answer:

x + 11

Step-by-step explanation:

Substitution!

Since you're trying to find f(x+10), you would replace each x in the equation (in this case only one) with x+10.

So instead of

[tex]x+1[/tex]

it would be

[tex](x+10)+1 = x + 10 + 1 = x + 11[/tex]

Answer:

12 hours

Step-by-step explanation:

126 dollars / 7 hours of work = 18 dollars per hour (Pretty neat honestly)

So she made 216 dollars / x = 18 dollars per hour

18x=216 (cross multiply)

216/18 = 12 hours of work

Answer: 12 hours

Step-by-step explanation:

It takes her 7 hours to make $126 dollars and we need to find out how many hours(a) to make $216

So this is the equation

7 hours= 126 dollars

a hours= 216 dollars

Cross multiply

126 x a = 7 x 216

126a = 1512

Divide both sides by 126

a= 12 hours

Answer:

It would be 3/4=9/12

Step-by-step explanation:

The proportion relationship of the given ratios is 3/4= 9/12 thus option (B) is correct.

The ratio is the division of the two numbers.

For example, a/b, where a will be the numerator and b will be the denominator.

Proportion is the relation of a variable with another. It could be direct or inverse.

As per the given,

In the fractions, 3/4

Multiply by 3 on the numerator and denominator.

3/4 x 3/3 = 9/12

3/4 x constant = 9/12

Remove constant.

3/4 ∝ 9/12

Hence "The proportion relationship of the given ratios is 3/4= 9/12".

Answer:

s=9

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    2*(4*s-16)-5*s-(-5)=0

Pull out like factors :

  4s - 16  =   4 • (s - 4)

Pull out like factors :

  3s - 27  =   3 • (s - 9)

3 • (s - 9)  = 0

Solve  :    s-9 = 0

Add  9  to both sides of the equation :

                     s = 9

Idk if this is confusing but I know the answer.
