Answer:

C

Step-by-step explanation:

The slope intercept of a line is y=mx +b where

  • m is the slope which is calculated as the vertical distance divided by the horizontal distance between two points.
  • b is the y-intercept for value on the y-axis for which the line crosses it.

This graph crosses the y-axis (the vertical line) halfway between -1 and -2. This  is -3/2. This means only answers a, c, and d are options.

The graph moves up from -3/2 to its next point at (-4,0). We calculate the slope using:

Slope:m=\frac{y_2-y_1}{x_2-x_1}

We substitute x_1=0\\y_1=-1.5 and x_2=-4\\y_2=2

m=\frac{2-(-1.5)}{-4-0}

m=\frac{2+1.5}{-4}=\frac{3.5}{-4} =-0.875

This decimal is equivalent to -7/8. This means C is the answer.

Melissa ran 6 2/5 miles north 2 3/4 west and 2 1/3 south how far did she run
alexgriva [62]

Answer:11.5

Step-by-step explanation:

distance=6 2/5 + 2 3/4 + 2 1/3

d=(5x6+2)/5 + (4x2+3)/4 + (3x2+1)/3

d=32/5 + 11/4 + 7/3

d=(12x32+15x11+20x7) ➗ 60

d=(384+165+140) ➗ 60

d=689 ➗ 60

d=11.5

If the 50th and 51st terms of an arithmetic sequence are 140 and 142, find the 1st term
morpeh [17]

Answer:

The first term is 42.

Step-by-step explanation:

The common difference is 142  - 140 = 2 so we have

50th term = a1 + 2(50 -1) = 140    where a1 is the first term

a1 + 98 = 140

a1 = 140 - 98 =  42.

Jake says adding 0 to an addendum does not change a sum. Is he correct
siniylev [52]
Nothing changes if you don't add anything. 

Example:

10+10=20
20+0=20
 
nothing changes.

6-2x=3+5x <br> Solve for x
evablogger [386]

Answer:

x=3/7

Step-by-step explanation:

6-2x=3+5x

subtract 5x from both sides

6-2x-5x=3

subtract 6 from both sides

-2x-5x=3-6

add like terms

-7x=-3

divide both sides by -7

x=3/7
