Answer:

1. -5

2. 0

Step-by-step explanation:

<em>1.</em> Distribute the Negative Sign:

=a−2a+−1(3a−(4a−5))

=a+−2a+−1(3a)+−1(−4a)+(−1)(5)

=a+−2a+−3a+4a+−5

Combine Like Terms:

=a+−2a+−3a+4a+−5

=(a+−2a+−3a+4a)+(−5)

Answer:

=−5

<em>2. </em>Distribute:

=(13)(5)+(13)(−t)+−5+t+(−12)(5)+(−12)(−t)

=65+−13t+−5+t+−60+12t

Combine Like Terms:

=65+−13t+−5+t+−60+12t

=(−13t+t+12t)+(65+−5+−60)

Write in standard form: a line through the origin with slope 2/3
nordsb [41]

Answer:

y = 2/3x

Step-by-step explanation:

Slope-intercept formula: y = mx + b

m = 2/3 because the slope is 2/3.

b = 0 because the y value of the origin is 0, as the point is at (0, 0).

That makes y = 2/3x + 0, but adding zero does nothing so you take it out to get y = 2/3x.

Which will equation show correctly we write an expression that represents the cost for a pair of shoes that is marked down 20% o
alukav5142 [94]

Answer:

A

Step-by-step explanation:

You can write an expression to represent the total cost of a pair of shoes. The price of the shoes is the variable r. The shoes are marked down 20% or 0.2r. So the new price of the shoes will be r - 0.2r. You will also have to pay a tax of 5% or 0.05 of the new price. This is written as 1.05(r - 0.2r). You can simplify it by doing whats in the parenthesis.

1.05(r - 0.2r) = 1.05r(0.8r) = 0.84r
