Answer:
The y - intercept is (0, 4)
Step-by-step explanation:
The equation x + 4y = 8 is in 'standard form.' Any line parallel to this line has an equation that looks exactly the same EXCEPT for the constant.
So, let's write out x + 4y = 8 and replace the 8 with C.
x + 4y = C
Now take the coordinates of the given point (4, 3) and substitute them into the above equation: 4 + 4(3) = C = 16
Thus, the equation of the line passing through (4, 3) is x + 4y = 16.
To find the y-intercept, set x = 0 and calculate y:
0 + 4y = 16, or y = 4
The y - intercept is (0, 4)
Let
L-------> the length of the rectangle
W------> the width of the rectangle
we know that
the perimeter of the rectangle is equal to
-----> because Tamara's using the whole ribbon
so
-------> equation A
-------> equation B
Substitute equation B in equation A
find the value of L
therefore
the answer is
The system of equations is
So you are first going to move the 7 to the other by adding it to 8. and 7 plus 8 equals 15. and then you are going to get Y by itself. and then you are going to divide 15 by 3 which equals 5. and thats your answer!!
Answer:
2
Step-by-step explanation:
6.9-2.1=4.8
4.8-2.8=2
We have two equations and two unknowns/variables
y = 2x + 4
y = x + 2
We can solve by substitution or by elimination.
Let's try substitution.
Since both equations are set equal to y, set the two equations equal to one another and solve for x.
x + 2 = 2x + 4
Use algebra to solve
x = -2
Now use this value of x in one of the original equations to solve for y.
y = x + 2
y = -2 + 2
y = 0
So the solution is (-2,0).
