Answer: (2, -3)
The solution of the equation 4x+y=5 and 3x+y=3 be (2 , -3) .
Step-by-step explanation:
As given the equations are .
4x+y=5
3x+y=3
Subtracted 3x+y=3 from 4x+y=5 .
Thus
4x - 3x + y - y = 5 - 3
x = 2
Put in the equation 4x+y=5 .
4 × 2 + y = 5
8 + y = 5
y = -8 + 5
y = -3
Therefore the solution of the equation 4x+y=5 and 3x+y=3 be (2 , -3) .

Answer:
y=1/2x+2
Step-by-step explanation:
The equation of a line is y=mx+b where m is the slope and b is the y intercept.
First we find the slope. We can start by picking any point. Let's say (0,2). From this to get to the next point we have to rise 1 and go to the right two. This gives us a slope of 1/2 (slope=rise/run). Now that we have the slope, we can find the y-intercept. This is where the line intercepts the y axis. Therefore x would be 0. The point (0,2) is where the line intercepts the y axis, so the y intercept is 2.
Now that we have the slope and the intercept we can right the equation.
y=1/2x+2
Answer:length of the strip =3 1/3 meters
Step-by-step explanation:
Step 1
Given that
Area of the rectangular strip= 2/3 square meter
width = 1/5 meter
length = ?
W e know that the formulae for area of a rectangle = Length x width
using this equation, we will solve for length
Step 2
area of the rectangular strip= Length x width
Length = Area / Width
2/3 square meter / 1/5 meter
Length= 2/3 x 5/1 = 10/3= 3 1/3 meter
