Answer:
C
Step-by-step explanation:
This is your current equation: y= 3x + b. Next, plug in one of your coordinates to the equation. It doesn't matter which one. I'm going to use the second ordered pair, so it should look like this: 5 = 3(0) + b. Multiply 3 and 0 to get 5 = b. So, your equation is y = 3x + 5. The correct answer is C. Hope this helped!
To convert these numbers to a percent, divide the subset by the total, then multiply by 100.
$241.50 (subset) divided by $1,050 (total)
Is 0.23. Next, multiply the quotient (0.23) by 100 to get your answer.
0.23*100 = 23.
The interest rate would be 23%.
4 * 500 = $2,000
<span>Then, you must calculate how much he earned by the commission: </span>
<span>$42,000 * 3% </span>
<span>(3% = 3/100) </span>
<span>42,000 * 3/100 = 420 * 3 = $1260 </span>
<span>Finally, you add what he earned form the commission plus the 4 weeks salary: </span>
<span>$2,000 + $1260 = $3,260</span>
Answer:
y = -7x + 12
Step-by-step explanation:
<em>y = mx + b</em>
The <em>m </em>(slope) is -7 and the <em>y </em>is 12, substitute the numbers into the equation
Answer:
See below, sorry for taking so long
Step-by-step explanation:
1.
A. Slope is rise over run or y2 - y1 divided by x2 - x1
We have (-5, 1) and (-3, 7)
7 - 1 / -3 - (-5)
6 / -3 + 5
6 / 2 = 3
Slope = 3
B. So point slope form is y - y1 = m(x - x1)
We know the slope so:
y - 1 = 3(x - (-5))
C. Using the point slope we can move things around to get slope-intercept:
y - 1 = 3(x + 5)
y - 1 = 3x + 15
y - 1 + 1 = 3x + 15 + 1
y = 3x + 16
D. Standard form is Ax + By = C:
y = 3x + 16
y - y = 3x + 16 - y
0 = 3x + 16 - y
0 - 16 = 3x + 16 - y - 16
-16 = 3x - y
3x - y = -16
