Answer:
y=x-3 (assuming your graph is counting by ones)
Step-by-step explanation:
Slope is 1, I chose two points.
0,-3 and 4,1
Then found the slope with those two points, which was 1.
Then I find the y-intercept, which is where the line and point crosses the y axis, which was -3.
So, I made my equation.
Answer:
x = 4 y = 7
Step-by-step explanation:
x + 3 = -1/2x + 9
x = -1/2x + 6
3/2x = 6
x = 4
y = (4) + 3
y = 7
Tim spends 500 minutes at the school.
Step-by-step explanation:
Given,
Time for lunch = 45 minutes
Time for study hall = 45 minutes
Total = 45+45 = 90 minutes
This represents 18% of the total minutes Tim spend at school.
Let,
x be the total minutes Tim spend at school.
18% of x = 90 minutes
Dividing both sides by 0.18
Tim spends 500 minutes at the school.
