Answer:
8.
Denote the equation : y = ax + b
Use the first 2 values of x and y in table:
3a + b = 21
5a + b = 35
Subtract the 2 equations:
=> 2a = 14 => a = 7 => b = 21 - 3 x 7 = 0
=> The solution is y = 7x
9.
Denote the equation : y = ax + b
Use the first 2 values of x and y in table:
5a + b = 17
10a + b = 22
Subtract the 2 equations:
=> 5a = 5 => a = 1 => b = 17 - 5 x 1 = 17 - 5 = 12
=> The solution is y = x + 12
Hope this helps!

Answer:
$400 and $1,000
Step-by-step explanation:
Let us assume the x be the amount invested in 7% account
And, 600 + x be the amount invested in 9% account
Now the equation is
7x% + 9%(600 + x) = $118
0.07x + 54 + 0.09x = $118
0.16x = $118 -$54
0.16x = $64
x = $400
And, the other one is = $400 + $600 = $1,000
Answer:
Hi there!
The correct answer is: Based on parent function, the graph vertically stretched by a factor of 2, shifting to the left by 1 unit and moving vertically down by 5.
Answer:
-5/7
Step-by-step explanation:
Look at the graph. As we move from left to right from (-3, 2) to (4, -3), x increases by 7 and y decreases by 5. Thus, the slope is
m = rise/run = -5/7.
