6 0

Answer:

-1

Step-by-step explanation:

We can find the slope given two points

m = (y2-y1)/(x2-x1)

  =( -4 -8)/(10--2)

   = (-12)/(10+2)

     -12/12

    -1

I need help asap plot it or locate it!
natulia [17]

You can plot this by turning the fraction into a decimal. -1&1/3rds is -1.333... and 1/6ths is about .16, so then you can find these points on the number line. Also, the number line has 6 points equal one, so the points by those.

How long will it take Greg to earn $500.00 round to the nearest hour
Mrrafil [7]

Answer:

56 hours

Step-by-step explanation:

we know that  

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=k or y=kx

Let

x -----> the number of hours

y ----> the amount earned in dollars

This problem represent a proportional relationship between the variable x and the variable y

Find the value of the constant of proportionality k

k=y/x

For (3,27) ----> k=27/3=9\ \$/h

For (9,81) ----> k=81/9=9\ \$/h

For (21,189) ----> k=189/21=9\ \$/h

The constant of proportionality k is 9

The linear equation is

y=9x

For y=$500

substitute in the equation and solve for x

500=9x

Divide by 9 both sides

x=56\ hours

Ede4ka [16]

Answer:

Step-by-step explanation:

Sum of all three angle in a triangle=180

Given angles are 35°,45°

Let the remaining angle =x

So 35 +45+X=180

X=180-80

X=100°

Remaining angle =X=100° is the answer
