Answer:

$285.12

Step-by-step explanation:

first, we'll solve for the 45% sale.

45/100

0.45 x 480

= 216

subtract from the original price

480 - 216

= 264

now we'll solve for the 8%

8/100

0.08 x 264

= 21.12

add the 45% and 8%

264 + 21.12 = 285.12

A positive integer squared plus 3 times it’s consecutive integer is equal to 43
Eduardwww [97]

Answer:

the integer is 5

Step-by-step explanation:

x^2+3(x+1)=43

x^2+3x+3=43

x^2+3x+(9/4)=43-3+(9/4)

(x+(3/2))^2=42 1/4

x+(3/2)=sqrt(42 1/4)

x+(3/2)=6 1/2

x=(6 1/2)-(3/2)

x=5

check:

5^2+3(6)=43

25+18=43

43=43

Given that the equation y=mx + b where m is 12 and the line passes through the point (-2,8), what would be the value of b?
larisa86 [58]

Answer:

d

Step-by-step explanation:

The answer would be D. We can continue the line from the point (-2,8) because we know the slope so we will continue it forward by two on the x axis. Since we go forward by two we are going up by 24 (12*2) on the y axis so the y intercept (b) would be 8 + 24 which is 32. Sorry if it is hard to understand.

Draw the following scenario using a vertical number line.
nekit [7.7K]
You would move your point 24 up from the starting point then move it three down from the 24 so if you start at zero go to 24 then move it down to 21.
