Answer:
D) < 3, 7)>
Step-by-step explanation:
<u><em>Explanation</em></u>:-
Given that the vector < 3 , -7 >
Given the vector reflection across the x-axis
(x,y) → (x , -y)
The vector < 3,-7> →< 3, -(-7)>
< 3,-7> →< 3, 7)>
Answer:
-7/3 =x
Step-by-step explanation:
5x-15 = 8x-8
Subtract 5x from each side
5x-5x-15 = 8x-5x-8
-15 = 3x-8
Add 8 to each side
-15+8 = 3x-8+8
-7 = 3x
Divide each side 3
-7/3 = 3x/3
-7/3 =x

Answer:
$466
Step-by-step explanation:
Represent her salary by s. Then the amount spent on rent is s/2.
After spending 168 on her electric and water bills, she had s/2 - 168 dollars left. She spent half of this on her phone bill, leaving her with
s/2 - 168
-------------- dollars.
2
After buying $57 worth of gas, she had
s/2 - 168
-------------- - 57 dollars left, and this came to $92.
2
We must now solve for s.
First, multiply all three terms by 2. We get
s/2 - 168 - 2(57) = 2(92), or
s/2 - 168 - 114 = 184
Simplifying this, we get s/2 = 168 + 114 + 184, or s/2 = 466.
She spent half her salary (that is, half of s) on rent. As seen above, this is $466.
Hi! Here's how you do this problem:
1. You want to turn the 7 into 6 12/12
2. Subtract the two
6 12/12 - 3 5/12 = 3 7/12
So your answer is 3 7/12. Hope I helped!
