All you have to do is 899 times .24 and then get that answer and subtract
Answer:
x = 1
Step-by-step explanation:
-5x-(-7-4x)-2(3x-4)
-5x + 7 - 4x - 6x + 8 First step is to factor all the numbers out so you have no parenthesis. In this case -(-7 just turns into + 7 because two negatives equal a positive. As well as -2*3x and -2*-4 which gives you -6x + 8.
-15x + 15 In this step you combine like terms.
-15x = -15 Next you move the whole number to the other side of the equation by subtracting it from both sides.
x = 1 Finally you divide -15 by -15 to get x by its self.
4x - y = 2
y = 4x
and 4x + y = 6
As all three of their gradients have been inverted (-1/m), meaning they are perpendicular.
Answer:
zeros: -11 , 7
Line of symmetry: x = -2
Step-by-step explanation:
y = 2x² + 8x - 154 = 2*(x² + 4x - 77) = 2*(x+11)(x-7)
y = 0
x = - 11 or x = 7
line of symmetry: x = 1/2 (-11 + 7) = -2
2x² + 8x - 154 = 2*(x² + 4x +4) - 162 = 2 * (x+2)² - 162
vertex (h , k): h = -2 , k = -162
Line of symmetry: x = -2
Answer:
110x -200y
Step-by-step explanation:
10(x - 20y) + 100x
Distribute
10x-200y +100x
Combine like terms
110x -200y
