Answer:
x = 3, and y = 2
Step-by-step explanation:
2x + 3y = 12 -------- (1)
y = x - 1 ---------------(2)
Substitute value of Y in (2) in (1)
2x + 3(x-1) = 12
2x + 3x - 3 = 12
5x - 3 = 12
5x = 12 + 3
5x = 15
x = 15/5
x = 3
Put the value of x in equation 2
y = x-1
y = 3 - 1
y = 2
Therefore, x = 3, and y = 2

Answer:
Number of year to get $10,000 as interest = 7.5 year (Approx)
Step-by-step explanation:
Given:
Initial investment = $20,000
Interest on investment = $10,000
Rate of interest = 5.6% = 0.056
Find:
Number of year to get $10,000 as interest:
Computation:
![Interest\ on\ investment = Initial\ investment[(1+r)^n-1]\\\\10,000 = 20,000[(1+0.056)-1]\\\\0.5=(1.056)^n-1\\\\1.5 =(1.056)^n\\\\n=7.44](https://tex.z-dn.net/?f=Interest%5C%20on%5C%20investment%20%3D%20Initial%5C%20investment%5B%281%2Br%29%5En-1%5D%5C%5C%5C%5C10%2C000%20%3D%2020%2C000%5B%281%2B0.056%29-1%5D%5C%5C%5C%5C0.5%3D%281.056%29%5En-1%5C%5C%5C%5C1.5%20%3D%281.056%29%5En%5C%5C%5C%5Cn%3D7.44)
Number of year to get $10,000 as interest = 7.44
Number of year to get $10,000 as interest = 7.5 year (Approx)
Answer:
Step-by-step explanation:
In the table, they give you an x-value. Use the x-value to solve for y. You will then get a point. Plot the points to find the graph.
y = 1/2x
y = 1/2(0)
y = 0
(0, 0)
y = 1/2x
y = 1/2(2)
y = 1
(2, 1)
y = 1/2x
y = 1/2(-4)
y = -2
(-4, -2)
