Answer:
where m is the slope of the line and b is the y-intercept of the line, or the y-coordinate of the point at which the line crosses the y-axis. To write an equation in slope-intercept form, given a graph of that equation, pick two points on the line and use them to find the slope.
Step-by-step explanation:
99 + 99x = 0
Subtract 99 from both sides:
99x = -99
Divide both sides by 99
X = -1
Answer:
7th week
Step-by-step explanation:
Let us represent the number of weeks as x
Jill begins the summer with $500 in her savings account. Each week, she withdraws $20.
$500 - $20× x
500 - 20x
Her brother, Sam,starts the summer with $150 in his account. He adds $30 to his account each week.
$150 + $30 × x
150 + 30x
At what week will both Jill and Sam have the same amount in their account?
We solve this be Equating both Equations together
Jill = Sam
500 - 20x = 150 + 30x
Collect like terms
500 - 150 = 30x + 20x
350 = 50x
Divide both sides by 50
50x/50 = 350/50
x = 7 weeks
Therefore, at the 7 week, Jill and sam would have the same amount in their accounts
For this case we have the following statement:
<em>"You have 2 meters of fabric and you cut 85% to make curtains, 50% of the rest to make the strips that hold it. How many centimeters of fabric were left?"</em>
So, we have:
2 meters ---------> 100%
x ----------------------> 85%
Where "x" represents the amount of fabric meters equivalent to 85%.
![x = \frac {85 * 2} {100}\\x = 1.7](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%20%7B85%20%2A%202%7D%20%7B100%7D%5C%5Cx%20%3D%201.7)
Thus, 1.7 meters of fabric were used to make curtains.
There are 0.3 meters of fabric left, of which half (50%) is used to make the strips that hold the curtain. That is to say:
![\frac {0.3} {2} = 0.15m](https://tex.z-dn.net/?f=%5Cfrac%20%7B0.3%7D%20%7B2%7D%20%3D%200.15m)
Thus, 0.15 meters of fabric remain.
![0.15 m * \frac {100 cm} {1 m} = 15\ centimeters.](https://tex.z-dn.net/?f=0.15%20m%20%2A%20%5Cfrac%20%7B100%20cm%7D%20%7B1%20m%7D%20%3D%2015%5C%20centimeters.)
Thus, 15 cm of fabric remain
Answer;
15 cm
