iren [92.7K]3 years ago
8 0

Answer: y = 3x - 19

Step-by-step explanation:

The equation of line in the slope intercept form is give as :

y = mx + c , where m is the slope and c is the y - intercept.

The points given : ( 4 , -7 )

slope = 3

Using the formula

y - y_{1} = m (x - x_{1} )

substituting the given values , we have

y - (-7) = 3 ( x - 4 )

y +7 = 3x - 12

y = 3x -12 - 7

y = 3x - 19

This gives the equation of the line in slope - intercept form.

xz_007 [3.2K]

Answer:

2 1/2

Step-by-step explanation:

The heaviest bag weighs 4 pounds, and the lightest bag weighs 1 1/2.

4 can be converted to 8/2 and 1 1/2 can be converted to 3/2.

8/2-3/2=5/2.

5/2 converts to 2 and 1/2 or 2.5

Triangle OPQ is similar to triangle RST. Find the measure of side RS. Round your answer to the nearest tenth if necessary. OPQR
Andrews [41]

Answer:

RS  =  75.3

Step-by-step explanation:

You need to set up the proportion of corresponding sides.

\frac{PQ}{ST}  =  \frac{PO}{RS}

\frac{7}{31}  = \frac{17}{RS}

7(RS) = 31(17)

         =  527

RS = 527/7 = 75.2857...

     =  75.3

What is the total finance charge for a $4,250 loan at 13.25% interest compounded monthly for 24 months? ( I hate asking for help
antoniya [11.8K]
<span>There is a formula for a loan : A = P * r * ( r + 1 ) ^n / (( r + 1 ) ^n - 1 ), where P is the loan and A is the monthly payment. So P = $4,250 and r = 0.1325 : 12 = 0.011. ( 13.25 % = 0.1325 and we divide it by 12, because the interest is compounded monthly ). A = 4,250 * 0.011 * 1.011^(24) / ( 1.011^(24) - 1 ) = 4,250 * 0.11 * 1.3 / 0.3 = 4,250 * 0.0477; A = $202.55. Finally we have to multiply this sum by 24 : the total finance charge: $202.55 * 24 = $ 4,861.20. Answer: D ) $4,861.20 </span>
