Answer:
y= x-4
Step-by-step explanation:
Since we have a point, and the slope, we can use the point slope formula
m is the slope, y1 is the y coordinate of the point and x1 is the x coordinate of the point.
We know that m is 1, y1 is 1, and x1 is 5, so we can substitute them in
y-1=1(x-5)
Solve for y by isolating it
Distribute the 1
y-1=1*x+ 1*-5
y-1=x-5
Add 1 to both sides
y=x-4
Answer: 8 1/3 hours or 500 minutes
Step-by-step explanation:
Keep in mind that there are 100 centimeters in a meter.
The snail moves at a pace of 12 cm/h, and needs to go 100 cm. You can just divide 100/12 to get 8 1/3, which is how many hours (groups of 12 cm) it takes for the snail to travel 100 cm (1 meter).
If necessary, you can also multiply 8 1/3 by 60 to get the number of minutes the snail takes. 8 times 60 is 480, and 1/3 of an hour is 20, so add 480+20 to get 500 minutes.
Answer:
40°
Step-by-step explanation:
Measure of Nonagon (9-sided polygon) = 1260°
Each angle measure = 1260 ÷ 9 = 140°
The value of x (the outside angle) = 180° - 140° = 40°
Answer:
(x-3) (x-4)
Step-by-step explanation:
x²- 7x + 12
= x² - 3x -4x +12
=x(x-3) - 4(x-3)
=(x-3) (x-4)

Answer:
Step-by-step explanation:
A) If the playing times are to be the same, then the two expressions for playing time will be equal to each other.
Ron = Sam
3 +1.25c = 8 +0.75c
0.50c +3 = 8 . . . . . . . . . . subtract 0.75c from both sides
0.50c = 5 . . . . . . . . . . . subtract 3 from both sides
c = 5/0.50 = 10 . . . . . divide by the coefficient of c
Each would have to complete 10 chores for their playing times to be the same.
__
B) When c = 4, we have ...
Ron: 3 +1.25·4 = 3 +5 = 8
Sam: 8 +0.75·4 = 8 +3 = 11
Sam spent the most gaming time if both completed 4 chores.
