Answer:
x < 5
Step-by-step explanation:
<u>Step 1: Solve for x</u>
-8x + 18 > -22
-8x + 18 - 18 > -22 - 18
-8x / -8 > -40 / -8
<em><u>When dividing by negative, it flips the sign</u></em>
x < 5
Answer: x < 5
Answer:
f(x)=4x(x-3)
Vertex=3/2, -9
Step-by-step explanation:
First, factorize it.
That is equal to 4x(x-3)
Therefore, x intercepts are 0 and 3, as at least one of them need to be 0.
To find the vertex, first find the x of the vertex, which you can do by finding the average of the x intercepts, so it will be 3/2
Then, find the y, by making x in the original equation equal 3/2. This will give us -9 as the y.
The vertex will by 3/2, -9
Answer:
If Krystal goes with plan A, She will save 120 dollars.
Step-by-step explanation:
Plan A costs 419.88 dollars per year (34.99*12= 419.88)
Plan B costs 539.88 dollars per year (134.97 * 4 = 539.88)
(Sounds desperate but can I get the Brainliest?)
If the questions are asking where the two equations meet the answer is (1,1)
