Answer:

42 ft, 60 ft, 84 ft

Step-by-step explanation:

let x be the shortest side , then the other 2 sides are 2x and x + 18, so

x + 2x + x + 18 = 186 , that is

4x + 18 = 186 ( subtract 18 from both sides )

4x = 168 ( divide both sides by 4 )

x = 42

Then lengths of sides are

x = 42 ft

2x = 2 × 42 = 84 ft

x + 18 = 42 + 18 = 60 ft

Answer:

Domain: (-∞,0) ∪ [0,∞)

Range: [-3,∞)

f(0) = -3

The domain of the function will be (-∞, 0) U [0, ∞).

The domain means all the possible values of x and the range means all the possible values of y.

A statement, principle, or policy that creates the link between two variables is known as a function. Functions are found all across mathematics and are required for the creation of complex relationships.

The function is a piecewise function.

Use the graph of the function to find the domain of f.

From the graph, the domain of the function will be (-∞, 0) U [0, ∞).

More about the domain and range link is given below.

Answer:

z = 5

Step-by-step explanation:

[tex]15z = - 2( - 11z + 10) - 15[/tex]

[tex]15z = 22z - 20 - 15[/tex]

[tex]15z = 22z - 35[/tex]

Step-by-step explanation:

It's simple I cannot really show my work but trust me

The rate of change represented by the graph is that the car drives down the mountain at a rate of 250 feets per hour.

The rate of change also called the gradient or slope is obtained using the relation :

Rate of change = change in y / change in x

Change in y = (y2 - y1)

Change in x = (x2 - x1)

From the graph :

y2 = 1500 ; y1 = 0

y2 = 1500 ; y1 = 0x2 = 6 ; x1 = 0

Hence,

Rate of change = (1500 - 0) / (6 - 0) = 1500 / 6 = 250

Answer:

D

Step-by-step explanation:

The length of the sidewalk is 25 + 4 + 4 = 33 ft

The width of the sidewalk is 4 ft

area of top/ bottom = 2(4 × 33) = 2 ×132 = 264 ft²

→ Note this area includes the 4 corners ←

area of 2 sides = 2(4 × 9) = 2 × 36 = 72 ft²

area of sidewalk = 264 + 72 = 336 ft² → D

Answer:

$30

Step-by-step explanation:

6 • 1/3 = 18

18 • 1/2 = 36

36 - 6 = 30

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

The operator that performs the arithmetic operation is called the arithmetic operator.

Operators which let do a basic mathematical calculation

+ Addition operation: Adds values on either side of the operator.

For example 4 + 2 = 6

- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.

for example 4 -2 = 2

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

/ Division operation: Divides left-hand operand by right-hand operand

For example 4/2 = 2

Given that after shopping Connie had 6 dollars left.

Connie spent one-third of her money at Cafe

So, 6 (1/3) ⇒ 18

Connie spent one-half of her money at Grocery Store

So, 18 (1/2) ⇒ 36

So, Connie spends total money at Allen's Grocery Store

⇒ 36 - 6

⇒ 30 dollars

Hence, Connie spends 30 dollars at Allen's Grocery Store.

Answer:

This equation is in y=mx + b form. Just plug in the point to get N, which is also B.

Whatever is in f(x) is your x. So x = 9; This means...

4 = 2/3(9) + n

Solving for n gets you -2.

Now we plug in -3 and also substitute N now that we solved for it.

f(-3) = 2/3(-3) - 2

f(-3) = -4
