<h3><u>The correct answer is: B.</u></h3>
We could use a graphing calculator to solve this easily, but let's just solve it by looking at the equation.
We'll need to turn this standard form equation into a slope-intercept form equation to be able to easily solve it.
Isolate y.
2x - 3y = 7
<em><u>Add 3y to both sides.</u></em>
2x = 3y + 7
<em><u>Subtract 7 from both sides.</u></em>
3y = 2x - 7
<em><u>Divide both sides by 3.</u></em>
y = 2/3x -7/3
Now, we can plug each x value in the answer choices into x to find the corresponding y value.
y = 2/3(7) - 7/3 = 2.34
As this y value does not match, A is not the answer.
y = 2/3(-4) - 7/3 = -5
This y value does match, so B is the correct answer.
y = 2/3(-9) - 7/3 = -8.34
This y value doesn't match either, so C is not the answer.
y = 2/3(9) - 7/3 = 3.67
This y value doesn't match either, so D is not the answer.
The amount of money he has before working at his job
Answer:
Use the interactive to graph the line that goes through the points (–4,–2) and (2,0).
The point (a,1) lies on the line you graphed.
What is the value of a? IT IS 5
Step-by-step explanation:
Here's the equation for one year:
0.0129(680) + 680
But because it is 3 years:
3(0.0129(680)) + 680
0.0387(680) + 680
We can make it simpler:
1.0387(680)
Multiply:
706.316
We can round up:
She will have $706.32, and earn $26.32
Fill 12 gallon tank for $48.74.
or buy gas for $3.80 a gallon.
$3.80 x 12= $45.60.
buying gas is cheaper by $3.14.
