I already answered this question, if you look back in your questions you should find this answered along with another one. I'll do it again just in case you don't find it.
Answer:
{y,x} = {-4,-2}
Expanation:
Solve by Substitution :
// Solve equation [1] for the variable y
[1] y = 2x
// Plug this in for variable y in equation [2]
[2] -2•(2x) - 8x = 24
[2] - 12x = 24
// Solve equation [2] for the variable x
[2] 12x = - 24
[2] x = - 2
// By now we know this much :
y = 2x
x = -2
// Use the x value to solve for y
y = 2(-2) = -4
Answer:
2(x-4)=3(x+10)
Step-by-step explanation:
Area is a square unit of measurement, which tells you how many square units a specific shape or object takes up. Length is a linear measurement, and refers to the number of unit segments one can place along a shape, line, or curve.
If a rectangle has a length of 8 inches and width of 6 inches, it occupies 48 square feet of space, but only has 28 inches of linear measurement.
Answer:
the first one is a function! there are no repeated x values in a function
A=1
B= -1
C= 1/4
B^2-4ac
(-1)^2 -4(1)(1/4)
1 -1
0 = 1 solution
