Answer:
Step-by-step explanation:
They both (36 and 45) go into 9. Divide them both by 9.
well if the area of rectangle is 5x² ... and x² has a value here ... so the coefficient 5 means that the answer is 5 × x²....
in other words ... we just have to multiply the value of x² with 5
Answer:
<em>Answer: False</em>
Step-by-step explanation:
<em>Relations vs Functions</em>
For a given relation between two variables x and y to be a function, it must meet the following condition: every value of x must be related to one and only one value of y.
When the graph of a relation is given, we can easily tell the difference by using the vertical line test as follows:
Imagine a vertical line moving through the x-axis. If any line touches the graph of the relation at more than one point, then the relation is not a function.
If we place vertical lines through the x-axis, they would touch the function twice at some values of x.
Thus, the graph is not a function
Answer: False
Answer:
It rained 1.29 inches in 3 hours
Step-by-step explanation:
<u>Step 1: Make an equation for the word problem</u>
It rained 0.43 inch each hour. What was the total amount of rainfall in 3 hours
0.43n
<u>Step 2: Plug in 3 for n</u>
0.43n
0.43(3)
1.29
Answer: It rained 1.29 inches in 3 hours
Answer:
n = sqrt(7) - 5 or n = -5 - sqrt(7)
Step-by-step explanation:
Solve for n:
(n^2 + 10 n + 18)/(n + 5) = 0
Multiply both sides by n + 5:
n^2 + 10 n + 18 = 0
Subtract 18 from both sides:
n^2 + 10 n = -18
Add 25 to both sides:
n^2 + 10 n + 25 = 7
Write the left hand side as a square:
(n + 5)^2 = 7
Take the square root of both sides:
n + 5 = sqrt(7) or n + 5 = -sqrt(7)
Subtract 5 from both sides:
n = sqrt(7) - 5 or n + 5 = -sqrt(7)
Subtract 5 from both sides:
Answer: n = sqrt(7) - 5 or n = -5 - sqrt(7)
