Laura got a discount of 100 dollars on her purchase of a 5775 bed.What is the percent of decrease?
matrenka [14]
Remember that percent means parts out of 100
x/100

discount is the decrease
so we divide the decrease by the original total and get
100/5775=0.0173
convert to fraction
0.0173/1
make bottom number 100
multiply by 100/100

-2(x+3)&lt;20 <br> Show work and write solution set
Digiron [165]

Answer:

x > - 13

Step-by-step explanation:

Given

- 2(x + 3) < 20 ← distribute parenthesis on left side

- 2x - 6 < 20 ( add 6 to both sides )

- 2x < 26

Divide both sides by - 2, reversing the symbol as a result of dividing by a negative quantity.

x > - 13

solution set is { x | x > - 13 }

Point B(6, -3) is translated using the rule (x -5 y + 9) what is the y coordinate of B'
Andrej [43]

This rule shows how we transition the x-coordinate and y-coordinate when finding B'.


In this rule, it shows us what to add/subtract from the x-value and y-value in the coordinate. We can see that it wants us to subtract 5 from the x-value (based on the "x - 5") and that it wants us to add 9 to the y-value (based on the "y + 9"). Based on this information, we can find B':

\textrm{B}'(6 - 5, -3 + 9)

\boxed{\textrm{B}\,'(1, 6)}


The "y-coordinate" of B' is 6.

Evaluate 3x - 4y + 11 for x = -2 and y = -1
katrin [286]

Answer:

9

Step-by-step explanation:

Plug in -2 for x, and -1 for y, and solve:

3x - 4y + 11

3(-2) - 4(-1) + 11

Remember to follow PEMDAS. First, multiply. Remember, that when you multiply:

2 positive signs will result in a positive answer.

1 positive & 1 negative will result in a negative answer.

2 negative will result in a positive answer.

3 * -2 = -6

-4 * -1 = 4

-6 + 4 + 11 = 9

9 is your answer.
