3(a + b) - 2a - 2b

simplify the algebraic expression

Answers

Answer 1

Answer:

a + b

Step-by-step explanation:

3(a + b) - 2a - 2b

open the parenthesis

3 * a + 3 * b - 2a -2b

3a + 3b - 2a - 2b

combine like terms

3a - 2a + 3b - 2b

a + b

Answer 2
You’d distribute the 3 to both a and b, which = 3a + 3b - 2a -2b, which would then = a + b. So a + b is the answer

Write an equation of the line through the point (-10, 0) with slope of -1/2

Answers

Answer:

y = 1/2x + 5

Step-by-step explanation:

We can use point slope form since we are given a point and the slope

y -y1 = m( x-x1)

where ( x1,y1) is a point and m is the slope

y -0 = 1/2 (x- -10)

y = 1/2( x+10)

y = 1/2x + 5

This is clearly a linear relationship. If Alex rented the movie for 0 days, he'd owe nothing. If he paid $6 for a 3-day rental, the slope of this line would be m = rise / run = $6/(3 days) = $2/day, which is positive.

A cell phone provider will allow you to buy a phone over time. They require a $50 initial payment and then charge $25 per month. If this situation were represented by a function, what would be the slope?

Answers

Answer:

25

Step-by-step explanation:

Given that:

Initial payment done for buying the phone = $50

Charges per month for the phone = $25 per month

To find:

The equation to represent the situation and its slope.

Solution:

First of all, let us assume that [tex]m[/tex] represents the number of months for which monthly is to be made.

Charges paid for one month = $25

Charges paid for [tex]m[/tex] months =  $25[tex]m[/tex]

Total cost of the phone = Initial payment + Charges paid for [tex]m[/tex] months

[tex]C = 25m + 50[/tex]

It is a linear equation between two variables [tex]C[/tex] and [tex]m[/tex].

This equation can be compared with slope intercept form of a line.

Slope intercept form of a line is represented by:

[tex]y=Mx+c[/tex]

[tex]M[/tex] is the slope.

On Comparing, we get:

[tex]y = C, M = 25, x = m, c = 50[/tex]

Therefore, the slope is 25.

Options A, B and C are the correct answers.

Given that, the bar chart shows the relative frequencies of students from grades 6 to 12 who participate in the community service activity.

How do you find relative frequency?

Relative frequency can be defined as the number of times an event occurs divided by the total number of events occurring in a given scenario.

Relative Frequency = Subgroup frequency/ Total frequency.

Relative Frequency = f/ n.

From the given bar chart we can see that

The maximum number of participating students was in grade 9.The number of participating students in grade 6 was equal to the number of participating students in grade 7.The relative frequency of all participating students in grades 6 and 7 combined was 0.60.  

Therefore, options A, B and C are the correct answers.

15 points and BRAINLIEST Alyssa invested $500 into an account. The value of the account after t years can be found using the function r(t) = 500(1.068). What is the percent annual rate of change
in the value of the account?

Answers

Answer:

annual rate: r = 0.068

Step-by-step explanation:

The formula is r(t) = P(1+r)^t

Since the time is already in years we just have to solve for the rate

1 + r = 1.068

r = 0.068

The rate of change in the value of account is 0.068

What is rate of change?

'Rate of change is used to mathematically describe the percentage change in value over a defined period of time.'

According to the given problem,

Annual rate:

r = 0.068

The formula is r(t) = [tex]P( 1 + r )^{t}[/tex]

Therefore, solving for the rate

⇒ 1 + r = 1.068

⇒ r = 0.068
