What is the slope of the line that passes through the points (-6, -8)(−6,−8) and (-14, 4) ?(−14,4)? Write your answer in simples

creativ13 [48]

Answer:

$\huge\boxed{slope=-\dfrac{3}{2}}$

Step-by-step explanation:

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have two points (-6, -8) and (-14, 4).

Substitute

$x_1=-6,\ y_1=-8,\ x_2=-14,\ y_2=4$

$m=\dfrac{4-(-8)}{-14-(-6)}=\dfrac{4+8}{-14+6}=\dfrac{12}{-8}=-\dfrac{12:4}{8:2}=-\dfrac{3}{2}$

Estimate 4704 - 1193 by first rounding each number to the nearest hundred.

sveticcg [70]

Answer:

$3500$

Step-by-step explanation:

Given the following question:

$4704-1193$

To estimate we to the nearest hundred we have to look at the number next to the hundreds place value to determine if it's greater than five.

$4704$

$0 < 5 = 4700$

$1193$

$9 > 5 = 1200$

$4700 - 1200$

$4700 -1200=3500$

$=3500$

Hope this helps.

On a $500 loan, Carla paid $60 interest at a rate of 8%. How long did she have the loan?

Anni [7]

Answer: 1 year, 5 months or 17 months

Step-by-step explanation:

Interest (I) = $60

Principal (P) = $500

Rate (R) = 8%

Time (T) =?

Since, Simple Interest (I) = (P x T x R) / 100

making T the subject of formula;

T = 100I / P x R

Inputting the values

T = 100 x 60 / 500 x 8

T = 6000 / 4000

T = 1 year, 5 months

Anna71 [15]

Answer:

The rate of change is 27.5 miles per hour

Step-by-step explanation:

Given:

Distance driven by mike = 110 miles

Time taken by mike to drive 110 miles = 4 hours

To Find:

Rate of change=?

Solution:

The rate of change is also known as speed . Here we have to find the speed at which the mike drives

So we know that

$Speed =\frac{Distance }{Time}$

Substituting the values

Speed = $\frac{110}{4}$

Speed =27.5
