Answer:
x = -7 or x = 1
Step-by-step explanation:
2x^2 + 4x - 7 = x^2 - 2x
x^2 + 6x - 7 = 0
(x + 7)(x - 1) = 0
x + 7 = 0 or x - 1 = 0
x = -7 or x = 1
Answer:
k = 4
Step-by-step explanation:
First, find the equations of each function.
f(x) = x/3 - 3
g(x) = x/3 + 1
Then plug these values for g(x) = f(x) + k.
x/3 + 1 = x/3 - 3 + k subtract x/3 on both sides
1 = -3 + k add -3 on both sides
k = 4 we're done!
and this makes sense because g(x) is just a translation of f(x) 4 units up.
Answer:
The line of symmetry is x=7
Step-by-step explanation:
I like to plug my given equations into a graphing calculator. If you don't own a graphing calculator I use this site called desmos that's free.
Hope this helps..
The total weight of the brick divided by pounds per cubic inch to get how many cubic inch(volume) is the brick.
5.76/0.08=72 cubic inches
Simplify 1,000^8=10^w.
What you can do it multiply 8 by 3 (Since there is 3 zeros). You will get w=24
