Step-by-step explanation:
Answer:
2x + 5y = -4
Step-by-step explanation:
The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it's pretty easy to find both intercepts (x and y). This form is also very useful when solving systems of two linear equations.
Answer:
Domain: {-1,0,1,2}
Step-by-step explanation:
The domain is the input values, or x values
Domain: {-1,0,1,2}
The equation for the leg length, y is y = (P - 2x - 4)/2
The length of the leg "y" is 3 feet
a) Given the perimeter of the trapezoid expressed as:
P=2x + 2y + 4.
We are to make <em>y the subject of the formula </em>as shown:
P = 2(x+y) + 4
P - 2x = 2y + 4
P - 2x - 4 = 2y
Swap
2y = P - 2x - 4
y = (P - 2x - 4)/2
Hence the equation for the leg length, y is y = (P - 2x - 4)/2
b) Give that P = 26 feet and x = 8feet
y = (P - 2x - 4)/2
y = (26 - 2(8) - 4)/2
P = 26-20/2
P = 6/2
y = 3 feet
This shows that the length of the leg "y" is 3 feet
