Answer:
4381.7
Step-by-step explanation:
26290 divided by 6 is 4381.71333333
since 3 is less than 5 and 1 is less than 3 all the nubers get eliminated.
Answer:
B
Step-by-step explanation:
Since the y coordinate of the vertex is -4, it has to be the rest of the equation subtracted by 4, which eliminates A and C.
Adding 5 puts it on the left side, so you have to subtract 5.
Then you add all the default info and the info we found out.
y = 2(x-5)^2-4
So technically by process of elimination, B must be the answer.
He earns 750 a week
52 weeks in one year
in one year he earns: 52* (750)=39000
X=6
Explanation:
solate the variable by dividing each side by factors that don't contain the variable.
Answer:
Part A) x = -3
Part B) x = 1, x = -7
Part C) x < -7
Part D) 2
Step-by-step explanation:
<h3>Part A)</h3>
2(x - 3) = 3x - 3
<em>open the parenthesis</em>
2 * x - 2 * 3 = 3x - 3
2x - 6 = 3x - 3
<em>subtract 2x from both sides</em>
2x - 2x - 6 = 3x - 2x - 3
-6 = x - 3
<em>add 3 to both sides</em>
-6 + 3 = x
-3 = x
<h3>
Part B)</h3>
|2x + 6| = 8
<em>split this into two equations:</em>
<em>2x + 6 = 8</em>
<em>&</em>
<em>2x + 6 = -8</em>
2x + 6 = 8
2x = 8-6
2x = 2
x = 1
2x + 6 = -8
2x = -8 - 6
2x = -14
x = -7
<h3>Part C)</h3>
-5(x + 1) > 30
<em>open the parenthesis</em>
-5x - 5 > 30
<em>add 5 to both sides</em>
-5x > 35
<em>divide both sides by -5</em>
x > -7
<em>since you divided by a negative, flip the sign.</em>
x < -7
<h3>
Part D)</h3>
f(x) = 4x - 3
<em>substitute x for 5</em>
5 = 4x - 3
5 + 3 = 4x
8 = 4x
2 = x
