PLEASE HELP! MUCH APPRECIATED. MATH IS SO HARD :(
yulyashka [42]

Answer:

see below

Step-by-step explanation:

x+ 7.05 = 45.3

Subtract 7.05 from each side

x+ 7.05-7.05 = 45.3-7.05

x =38.25

Let x be the number

x+3.5 = -4.3

Subtract 3.5 from each side

x+3.5 - 3.5 = -4.3-3.5

x = -7.8

x is the cost of the drawing tablet

x+ 3.95 = 6.94  correct

The second equation add the total cost plus the cost of the drawing tablet  and sets it equal to the cost of the pencils.  This is not correct

6.94+x = 3.95   incorrect

The general point-slope equation for a str. line is y-k = m(x-h),

where m is the slope and (h,k) is a point on the line.

Given that the line passes thru (-4,6) and (1,2), we find the slope as follows:
           6-2
m = ----------- = -4/5
          -4-1

Subst. -4/5 for m, 6 for k and -4 for h     in    y-k = m(x-h):

y-6 = (-4/5)(x+4)

Compare this result to the equations given.
