Answer:
x = -3
Step-by-step explanation:
Hi!
Let's go step by step as simple as possible.
2x + 3 + 7x = -24
Now we can add like terms:
9x + 3 = -24
We subtract three:
9x = -27
Divide by nine:
x = -3
Thus, the answer is .
Check:
2 × (-3) = -6 + 3 = -3
7 × (-3) = -21
-21 + -3 = -24
So we are correct.
Answer:
We were given the equation of a rainbow, which follows a parabolic path, which is
By comparing to the vertex form,
We have the vertex at (h,k)=(1,6)
Since a=-0.1<0, the parabola opens down.
At y-intercept, x=0.
Step-by-step explanation:
Let's start by going left to right:
50000/50000 * 600 * 700.
50000/50000 cancels each other out so it's 1.
1 * 600 * 700.
600 * 700 = 420000
1 * 420000 = 420000
Put x = -6 to the expression:
