In order to find an average, you have to add all the numbers and divide by the number of things you added.
120.37 + 108.45 + 114.86 = 343.68
343.68/3 = 114.56
She spent an average of $114.56 each month on groceries.
Answer:
8
Step-by-step explanation:
According to Euclidean theorem
m^2 = 4×16
m^2 = 64
m = 8
9^-2 = 1/81 or 0.0123
When there is a negative in front of the exponent it makes a fraction. It is usually just 1/the number it equals if it were positive.
Answer:
Solution: (-4, 2), x= -4 and y =2
Step-by-step explanation:
-8x - y = 30
-2y = x
Substitute for x
-8*(-2y) - y = 30
16y - y = 30
15y = 30
y = 30/15 = 2
Then x = -2y = -2*(2) = -4
Solution: (-4, 2), x= -4 and y =2
<u>Answer:</u>

<u>Step-by-step explanation:</u>
To find the equation of the line, let's first consider the points whose coordinates we have been given:
• (6, 1)
• (2, 0).
The point (2, 0) is what is called the x-intercept, which is the point where the line crosses the x-axis. This means that at this point, the y-coordinate of the line is 0.
Next, let's calculate the slope (gradient) of the line using the formula:

where:
m = gradient,
and
= points on the line.
Using the formula:

⇒ 
Finally, now that we have two points on the line as well as the line's slope, we can use the following formula to find the equation of the line:

You can use any of the points on the line as
and
.
Using (2, 0):

⇒ 
Therefore the equation of the line is
.
