Answer:
y = m x + b equation of a straight line
m m' = -1 condition for perpendicular lines
If y = 4 x - 7 then m = 4 so m' = -.25
Y = -.25 X + A we need to find A
A = Y + .25 * 8 = 2 + 2 = 4
Y = -.25 X + 4
Check:
2 = -.25 * 8 + 4 = -2 + 4 = 2
Answer: 3^5 / 3^(-2) = 3^(3)
You should look for outliers. If there is an outlier then you should use median because if you use mean the data would be skewed.
Answer:
<em>The total change in his account is represented by the integer -5</em>
Step-by-step explanation:
<u>Operations With Integers</u>
We need to perform addition and subtraction to complete the answer to this problem.
Derrick first withdrew $17 from his account. Since the money is coming out from the account, it's considered as negative. Thus this operation is recorded as -$17.
The next day he deposited $12, which is considered as positive. This operation is considered as $12 or +$12.
The net operation or total change in the account is: -$17 + $12.
Subtracting and simplifying: -$17 + $12 = -$5
The total change in his account is represented by the integer -5
Answer:
c. both
Step-by-step explanation:
Given equation is 
Now we need to check if the graph of is symmetric with respect to which axis?
a. x-axis c. both b. y-axis d. neither
We know that if f(-x) reflect the graph about y-axis
so let's change x by -x into given function to see if that equation remains unchanged or not
That is same as previous equation.
<u>Hence given graph is symmetric about y-axis.</u>
We know that if -f(x) reflect the graph about x-axis
so let's change y by -y into given function to see if that equation remains unchanged or not
That is same as previous equation.
<u>Hence given graph is symmetric about x-axis.</u>
So the correct choice is c. both
