Answer:

17b - 2

Step-by-step explanation:

5b - 5 - 12b - 7

Say bye to the 12b, and add 12 to it and the 5.

5b + 12 = 17b

17b - 5 - 7

Add 5 to the 5 and the -7.

-7 + 5 = -2.

Now you have 17b - 2. You can’t go farther, so there’s your answer.

what are the intercepts of the equation 2.5x+8y=200 and/or how can i write it in slope intercept form

Inessa05 [86]

Answer:

The slope is -.3125 and the y intercept is 25

The x intercept is 80

Step-by-step explanation:

2.5x+8y=200

We want to get this in slope intercept form so we will solve for y

Subtract 2.5x from each side

2.5x-2.5x+8y=-2.5x +200

8y = -2.5x +200

Now divide by 8 on both sides

8y/8 = -2.5x/8 + 200/8

y = -.3125x +25

This is in the form y = mx+b where m is the slope and b is the y intercept

The slope is -.3125 and the y intercept is 25

To find the x intercept, set y = 0 and solve for x

2.5x+8y=200

2.5x = 200

Divide by 2.5 on each side

2.5x/2.5 = 200/2.5

x =80

Use the FOIL method to find the product. (x - 8)(x + 3)

Sliva [168]

Greetings and Happy Holidays!

FOIL stands for: First Outside Inside Last

FOIL is the order in which you would multiply (distributive property) the different terms:
$(x - 8)(x + 3)$

Multiply the First terms $(x)(x)$ :
$=x^2$

Multiply the Outside terms $(x)(3)$ :
$=x^2+3x$

Multiply the Inside terms $(-8)(x)$ :
$=x^2+3x-8x$

Multiply the Last terms $(-8)(3)$ :
$=x^2+3x-8x-24$

Simplify the expression:
$=x^2-5x-24$

The Answer Is:
$\boxed{=x^2-5x-24}$

I hope this helped!
