Answer:
x = -5
Step-by-step explanation:
the first step is calculate the sum.
-9x - 31 = 14
Then move the constant to the right side and change the sign.
-9x = 14 + 31
Then add the numbers
-9x = 45
Then divide both sides of the equation by -9
x = -5
The answer is 28
Explanation:
18⅔ ÷ ⅔
= 56/3 ÷ 2/3
= 56/3 x 3/2
= 56/2
=28
Answer:
300
Step-by-step explanation:
Let x = cost of desktop computer; then x - 250 = cost of laptop computer
converting % to decimals, 9% = 0.09 and 6% = 0.06
Then, 0.09x + (x - 250)0.06 = $300
0.09x + 0.06x - 15 = $300
0.15x = $315
x = $2100
then x - 250 = $1850
Proof: $2100•0.09 + 1850•0.06 = $189 + $111 = $300
The equation of the line that is parallel and passes through the point (2,3) is; x +2y =8.
<h3>What is the equation of the line that passes through (2,3)?</h3>
If follows from the task content that the slope of the first line is; (-4-0)/(4-(-4)) = -1/2.
Hence, since the lines are parallel, they have the same slope and the equation of the second line is;
-1/2 = (y-3)/(x-2)
-x+2 = 2y -6
x +2y =8.
