Answer:

The slope-intercept form is y=\frac{1}{2}x+\frac{11}{2}

Step-by-step explanation:

To find the slope, use

m=\frac{y^2-y^1}{x^2-x^1}

Replace the x and y values with the points.

m=\frac{7-5}{3-(-1)}

Solve.

m=\frac{2}{4}

m=\frac{1}{2}

After that, find the y-intercept form.

Put the equation in point-slope form.

y-5=\frac{1}{2}(x+1)

Replace x with 0.

y-5=\frac{1}{2}(0+1)

y-5=\frac{1}{2}

Add 5 to both sides.

y=5\frac{1}{2}

Convert to improper fraction form.

The y-intercept is \frac{11}{2}

Now finally, write in slope-intercept form. (y=mx+b)

m is slope, b is the y-intercept.

Ralph Chase plans to sell a piece of property for ​$150000. He wants the money to be paid off in two ways a - ​short-term note a
Artyom0805 [142]

Answer:

Amount on 11% note = $106,666.67

Amount on 8% note = $43,333.33

Step-by-step explanation:

Let the amount for the ​short-term note at ​11% interest be x.

Thus, the amount for the ​short-term note at ​8% interest will be (150000 - x)

Now we are told that the total interest paid is $15,200.

Thus;

0.11x + 0.08(150000 - x) = 15200

0.11x + 12000 - 0.08x = 15200

Rearranging gives;

0.03x = 15200 - 12000

0.03x = 3200

x = 3200/0.03

x = $106666.67

Thus, amount for 8% note = $150000 - $106666.67 = $43,333.33

-3(4r-8)=-36. <br> HELP!!! Don’t know the answer. Btw, 8th grade homework!! ;)
Dominik [7]
*Sorry I messed up my math please read the new answer.
Use distrubitive property to get rid of parentheses. Multiply -3 by 4r and -8 to get -12r+24=36. Then zero out 24 by subtarcting 24 from both sides. You. should then have -12r=12. Divide by -12 on both sides to get r by itself. Your answer should be r=1*. Hope this helps :)
