Answer:
-7
Step-by-step explanation: an easy way to find the y-intercept (the point at which the line crosses the y axis) is by identifying what part of the equation does not have an x value. in this problem, it would be -7. if it were to not have a number that is followed by an x the y-intercept is 0.
hope that helps!
Answer:
x^2 + y^2 = 49
Step-by-step explanation:
The equation of a circle is given by
( x-h) ^2 + (y-k) ^2 = r^2
(h,k) is the center of the circle and r is the radius
The circle is centered and (0,0) and the radius is 7
( x-0) ^2 + (y-0) ^2 = 7^2
x^2 + y^2 = 49
A-62 i believe hope it's right
So you use 40 gallons of water *PER* day.
Average water use in Dec?
(hint: in math * means multiplication)
Dec. has 31 days
so
40 * 31
1240
Average water use is 1240 gallons
Hope this helps :)
