Brandon went to the store and spent $2.50 on pencils. He spend half of what he had left on a notebook and paper. When he got home he had $5.00 left. How much money did Brandon have before going to the store?

A) make a table, chart or list
B) work backwards
C) use a formula
D) look for a pattern

Answers

Answer:

B) work backwards.

Step-by-step explanation:

Since they are asking for how much money he had at first and they displayed how much he spent without telling the amount of money at the start of the question, this is definitely a backwards question. For working backwards, you will need to do workings the opposite as what they said in the question.

Expand.If necessary, combine like terms (2x-3)(2x-3)

Answers

The expression (2x-3)(2x-3) can be written as (2x-3)² or 4x² - 12x + 9 after expanding by using the identity (a - b)² = a² -2ab + b²

What is an expression?

It is defined as the combination of constants and variables with mathematical operators.

We have given an expression:

= (2x-3)(2x-3)

After multiplication:

= (2x-3)²

We can also expand the above expression by using the identity:

(a - b)² = a² -2ab + b²

= 4x² - 12x + 9

Thus, the expression (2x-3)(2x-3) can be written as (2x-3)² or 4x² - 12x + 9 after expanding by using the identity (a - b)² = a² -2ab + b²

Carmine pain an electrician x dollars per hour for a 5 hour job plus 70 for parts. The total charge was 320 which equation can be used to determine how much do electrician charge per hour

Answers

Answer:

5x + 70 = 320

Step-by-step explanation:

We know that Carmine paid an electrician a certain amount per hour, we also know that they worked for 5 hours. Therefore we have 5x.

He also got paid 70 for parts, meaning an extra $70

And we know that we have the total charge and that the main point of this question is to determine how much the electrician was paid per hour.

Therefore :

5x + 70 = 320

The diameter of a cylindrical construction pipe is 6 ft. If the pipe is 34 ft long, what is its volume?

Answers

Given:

The diameter of the cylindrical pipe = 6ft.

Height of the pipe = 34 ft

To find:

The volume of the pipe.

Solution:

We have,

Diameter of cylinder = 6 ft

Radius of cylinder [tex]=\dfrac{6}{2}=3[/tex] ft

Height of the pipe = 34 ft

Volume of a cylinder is

[tex]V=\pi r^2h[/tex]

Where, r is the radius and h is the height.

Putting r=3 and h=34, we get

[tex]V=\pi (3)^2(34)[/tex]

[tex]V=\pi (9)(34)[/tex]

[tex]V=306\pi [/tex]

[tex]V=306(3.14)[/tex]

[tex]V=960.84[/tex]

Therefore, the volume of the cylindrical pipe is [tex]306\pi \approx 960.84[/tex] cubic ft.

What is y = mx + b mean for functions

Answers

Answer:

Slope-Intercept Form. A function whose graph is a line or a part of a line is called a linear function. In general, a linear function is a function that can be represented by an equation in the form y = mx + b. The form y = mx + b, or f(x) = mx + b, is called the slope-intercept form of a linear equation

Step-by-step explanation:

hope this help:))

the slope is the number "m" that is multiplied on the x, and "b" is the y-intercept (that is, the point where the line crosses the vertical y-axis). This useful form of the line equation is sensibly named the "slope-intercept form"
