Percent decrease: (original number - new number) / original number....x 100
percent decrease : (6.50 - 4.25) / 6.50....x 100
2.25 / 6.50 = 0.346....x 100 = 34.6% <==

- Solving for y on question - 5x - 4y = -81 |
- Answer : y = x +
<h2>
Step-by-step explanation:</h2>
<em>(Solving for x on question - 2x + 3y = 32)</em>
2x + 3y = 32
Step 1: Add -3y to both sides.
2x + 3y + −3y = 32 + −3y
2x = −3y + 32
Step 2: Divide both sides by 2.
=
<u>x = </u><u>⁻y + 16</u><u> </u>
<em>(Solving for y on question - 2x + 3y = 32)</em>
2x + 3y = 32
Step 1: Add -2x to both sides.
2x + 3y + −2x = 32+ −2x
3y = −2x + 32
Step 2: Divide both sides by 3.
=
<u>y = </u><u>x + </u><u> </u>
<em>(Solving for x on question - 5x - 4y = -81)</em>
5x − 4y = −81
Step 1: Add 4y to both sides.
5x − 4y + 4y = −81 + 4y
5x = 4y − 81
Step 2: Divide both sides by 5.
=
<u>x = </u><u>y + </u><u> </u>
<em>(Solving for y on question - 5x - 4y = -81 )</em>
5x − 4y = −81
Step 1: Add -5x to both sides.
5x − 4y + −5x = −81 + −5x
−4y = −5x − 81
Step 2: Divide both sides by -4.
=
y = x +
Answer:
d. -4/5
Step-by-step explanation:
When using the equation m = y2 - y1 / x2 - x1, we get m = 5-1 / -3-2.
Simplified: m = 4/-5.
The negative can be placed on the numerator or denominator, it doesn't make a difference.
Answer:
A, D
Step-by-step explanation:
b. mx+b can't describe the relationship of a vertical line since it's slope is undefined
c. x = -8 shows no relation to anything so it isn't a function
hopefully that works
