Well you would 12 12 because you double the number twice ad you would do 12 in 12 and you get 24
Answer:
88.5
Step-by-step explanation:
75 x .18
tip= 13.5
75 + 13.5 = 88.5
Answer:
y =-1/4x -8
Step-by-step explanation:
3x+12y=-96
Slope intercept form is y = mx +b where m is the slope and b is the y intercept
Subtract 3x from each side
3x -3x+12y=-3x-96
12y = -3x-96
Divide each side by 12
12y/12 = -3x/12 -96/12
y =-1/4x -8
Answer:
Your answer is B.
Step-by-step explanation:
So you do 3x+5x-10 (cuz your multiplying) then you add the x which is 3x+5x you get 8x-10
There are several ways in which we could answer this question. My choice is to actually solve the given quadratic equation, x^2 + 4x + 4 = 12.
Note that x^2 + 4x + 4 is a perfect square. Thus,
x^2 + 4x + 4 = 12 is the same as (x+2)^2 = 12, so that
x+2 = plus or minus √3*√4, or plus or minus 2√3.
Thus, the two real, unequal roots are
x = -2 + 2√3 and x = -2 - 2√3. These correspond to answer choices C and E.
