Answer:

164 feet per minute

Step-by-step explanation:

3 kilometers is ~9842.52 feet

Since it moves 9842.52 feet per hour, we can just divide that number by 60 which gives us 164.042 feet. Rounded it's 164 feet

Answer:

3800

Step-by-step explanation:

Variables:

O - Original cost

N - New cost

c - change factor

Step 1:

Recognize that if something decreases by 19%, it is worth 19% less

This means that the new price, fractionally, is 100% - 19% = 81%

So we can use c as 0.81 (81/100)

Step 2:

Write an equation to represent what is happening

N = O * c

Step 3:

Sub in what we know

3078 = O * 0.81

Step 4:

Rearange and solve

O = 3078 / 0.81 = 3800

Answer:

3rd option and 2nd option

Step-by-step explanation:

(10)

A linear pair sum to 180° , then

x - 30 + x + 76 = 180 , that is

2x + 46 = 180 ( subtract 46 from both sides )

2x = 134 ( divide both sides by 2 )

x = 67

Then

∠ 1 = x - 30 = 67 - 30 = 37°

∠ 2 = x + 76 = 67 + 76 = 143°

-------------------------------------------------------

(11)

Since T is the midpoint of SU , then

ST = TU , that is

5x = 3x + 32 ( subtract 3x from both sides )

2x = 32 ( divide both sides by 2 )

x = 16

Then

ST = 5x = 5(16) = 80

TU = 3x + 32 = 3(16) + 32 = 48 + 32 = 80

SU = 5x + 3x + 32 = 8x + 32 = 8(16) + 32 = 128 + 32 = 160

Answer:

26

Step-by-step explanation:

It says find f(f(2)), so we need to find f(2) and then input that into the same function. f(2)=5 so then we input that into the function again and get 26. Boom.

Answer:

26

Step-by-step explanation:

Ok first u find f(2) so for that u have to input 2 into the value of x. So 2^2 +1 =5

When we get 5 we input THAT into f(x)

So:

F(5) = 5^2 +1

=26

Answer: a + 3b = 8

Step-by-step explanation:

a + b = 4 is true, since (2,2) works:  2 + 2 = 4

Try (2,2) in the options to find which one is true for (2,2):

A)  2 + 3*2 = 4?  No.

B)  4 + 4 = 2?  No.

C)  8 + 8 = 8?  No.

D)  2 + 6 = 8?  YES.

Therefore, a + 3b = 8 can be another valid equation.

Answer:

D. a + 3b = 8

Answer:

7x - 3)

Step-by-step explanation:

Given

3x - 7 + 2(2x - 7) ← distribute parenthesis

= 3x - 7 + 4x - 14 ← collect like terms

= 7x - 21 ← factor out 7 from each term

= 7(x - 3)

The expression 3x - 7 + 2(2x - 7) can be written as the product of 7 and the factor (x - 3).

We have write the expression 3x - 7 + 2(2x - 7) as the product of 7 and another factor.

we can simplify the expression first and then factor out the common factor of 7.

Let's simplify the expression step by step:

3x - 7 + 2(2x - 7)

= 3x - 7 + 4x - 14 (distributing the 2 to the terms inside the parentheses)

= (3x + 4x) + (-7 - 14)

= 7x - 21

Now, let's factor out the common factor of 7:

= 7(x - 3)

Step-by-step explanation:

the sum of all angles in a triangle is 180 degrees.

so,

x + (x - 6) + (2x + 34) = 180

x + x - 6 + 2x + 34 = 180

4x + 28 = 180

4x = 152

x = 38 degrees

x - 6 = 32 degrees

The slope of the graph in decimal form is 1.08.

By geometry we know that a line can be constructed after knowing the location of two distinct points. Lines in explicit form are defined by slope and intercept, the former is calculated by the secant line equation and the intercept by solving a linear function.

If we know that [tex](x_{1}, y_{1}) = (4.2, 9.6)[/tex] and [tex](x_{2}, y_{2}) = (6.7, 12.3)[/tex], then the slope of the graph is:

[tex]m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

[tex]m = \frac{12.3-9.6}{6.7-4.2}[/tex]

[tex]m = 1.08[/tex]

The slope of the graph in decimal form is 1.08.
