Answer:
f(6) =
Step-by-step explanation:
To evaluate f(6) substitute x = 6 into f(x), that is
f(6) = = =
Answer:
E. All values of x are solutions
Step-by-step explanation:
- -15x + 4 ≤ 109
- -6x + 70 > -2
Solve for x in the first equation. Subtract 4 from both sides.
-15x ≤ 105
Divide both sides by -15. Since this is a negative number the sign will flip.
x ≥ -7
Solve for x in the second equation. Subtract 70 from both sides.
-6x > -72
Divide both sides by -6; the sign flips.
x < 12
Since this is an OR problem we won't be combining the two solutions for x. Therefore you would graph x ≥ -7 and x < 12 separately.
The graph would look like this: (image attached)
Since the two lines cross pathways to cover the entire number line, this means that there are infinite values of x.
The answer should be E.
Answer:
Step-by-step explanation:
First, divide by 4 from both sides.
Solve.
Therefore, the solutions of 4x>8 is 2.
In conclusion, the correct answer is x=2.

Answer:
y = 26.45 + 32.45x - 9.25x
Step-by-step explanation:
Given the data:
X : _____ 0 _____ 1 ______2 _______ 3
Y : _____29 ____42 _____62 ______ 38
The quadratic regression model has the general equation :
y=A+Bx+Cx2
Fitting the data using a quadratic regression calculator, the equation of best fit obtained is ;
y = 26.45 + 32.45x - 9.25x

x - 13 < -11
<u>Step 2: Solve for </u><u><em>x</em></u>
- [Addition Property of Equality] Add 13 to both sides: x < 2
Here we see that any value <em>x</em> smaller than 2 would work as a solution.
