A and c would equal 70 degrees
And d would equal 110 degree
-1/2(-3/2x + 6x + 1) - 3
Simplify.
(3/4x - 3x - 1/2) - 3
Get rid of the parenthesis.
3/4x - 3x - 1/2 - 3
Add like terms.
(3/4x - 3x) + (-1/2 - 3)
Simplify.
-2 1/4x + (-3 1/2)
Get rid of the parenthesis.
-2 1/4x - 3 1/2
Hope I helped! :)
F(x) = 3x-1
g(x) = x+2
Find (f-g)(x), this means we need to subtract g from x.
(3x-1) - (x+2)
Subtract the like terms:
3x -x = 2x
-1 -2 = -3
Combine them to get 2x-3
The answer is A.
Answer:
C
Step-by-step explanation:
A system of equations has infinitely many solutions when the two lines representing the equations coincide. i.e. the two equations are the same or a multiple of each other.
2y - 4x = 6
2y = 4x + 6
2y = 2(2x + 3)
y = 2x + 3
-y = -(2x + 3)
-y = -2x - 3
Hence the other equation is -y = -2x - 3
Answer:
Slope: 0
x-intercept: there isnt one
y-intercept: 2
Step-by-step explanation:
the easiest way to look at this is to put it in the form y=mx+b where m is the slope and b is the y intercept. when we just think about what y=2 would look like, we can imagine a straight horizontal line at y=2. No matter what x value you choose, y will always equal 2. We know the slope (m) of any horizontal line is zero because there is no rise and zero divided by anything is going to be zero. we also know if y is always equal to 2 the y intercept will be 2. this would give us y=0x+2. to find the x intercept we just need to set y equal to zero in this equation. this gives us 0=0x+2 or 0=2 which can never be true, therefore there will be no x intercept.
