Draw the graphs of the lines below on the same grid to find the coordinates of the point of intersection. y + 5 = 2 x y = 7 − 2
1 answer:
Answer:
The point of intersection is (3,1)
Step-by-step explanation:
Manipulate these equations to achieve the form of y = mx + c
1) y + 5 = 2x
Y = 2x - 5
2) y = 7 - 2x
Y = -2x + 7
Point of intersection is (3,1) on the graph attached
To check algebraically:
2x - 5 = -2x + 7
4x = 12
X = 3
Substitute to get y
Y = 2x - 5
Y = 2 x 3 - 5
Y = 1
Therefore (3,1)

The investment will be $2653.30 after 20 years.
Step-by-step explanation:
Given,
Principal(P) = $ 1000
Time (T) = 20 years
Rate of interest(R) = 5%
To find the amount after 20 years
Formula
Amount(A) = P
Now putting the values of P, T and R we get,
A = $1000
=$ 1000
=$ 2653.297
= $ 2653.30
Hence, the investment will be $2653.30 after 20 years.
