Answer: D

Explanation: The function is an absolute value function with vertex at (-9,0). The slope of the part with x value greater than -9 is positive, and the slope of the part with x value less than -9 is negative.

If f(x)= negative -3x +4 and g(x)=2 solve for the value of X for the which f(x) =g(x) is true

Sever21 [200]

Answer:

x = -2/3

Step-by-step explanation:

Step 1: Convert signs

f(x) = -(-3x) + 4

f(x) = 3x + 4

Step 2: Set f(x) and g(x) equal to each other and solve for <em>x</em>

3x + 4 = 2

3x = -2

x = -2/3

And we have our final answer!

A chef got 7 bags of onions. The red onions came in bags of 8 and the yellow onions came in bags of 3. If the chef got a total o

frutty [35]

Answer:

$\#\text{ of 8-onion bags: }4,\\\#\text{ of 3-onion bags: }3$

Step-by-step explanation:

Let $a$ be the number of bags with 8 onions and let $b$ be the number of bags with 3 onions. We have the following system of equations:

$\begin{cases}a+b=7,\\8a+3b=41\end{cases}$

Subtracting $b$ from both sides of the first equation, we get $a=7-b$ . Substitute this into the second equation:

$8(7-b)+3b=41,\\56-8b+3b=41,\\56-5b=41,\\-5b=-15,\\b=\boxed{3}$

Therefore, the number of 8-onion bags is:

$a=7-b,\\a=7-3,\\a=\boxed{4}$

Thus, the chef got 4 8-onion bags and 3 3-onion bags.

A manufacturer of chocolate chips would like to know whether its bag filling machine works correctly at the 418 gram setting. It

VMariaS [17]

Answer: There is sufficient evidence to support the claim that the bags are under-filled.

Step-by-step explanation:

Since we have given that

$H_0:\mu=418\\\\H_a:\mu$

Sample mean = 411

Standard deviation = 20

n = 9

So, the test statistic value is given by

$z=\dfrac{\bar{x}-\mu}{\dfrac{\sigma}{\sqrt{n}}}\\\\\\z=\dfrac{411-418}{\dfrac{20}{\sqrt{9}}}\\\\\\z=\dfrac{-7}{\dfrac{20}{3}}\\\\\\z=-1.05$

At 0.025 level of significance,

critical value z = -2.306

since -2.306<-1.05

so, we will reject the null hypothesis.

Yes, there is sufficient evidence to support the claim that the bags are underfilled.
