Explain why 0.02 x 0.3 = 0.006. Answer in at least 2 complete sentences.
Answer:
.02*.03=.006 because when you multiply decimals after you get your answer you need to move the decimal point over 3 spaces. You do this because when you move the decimal point out three to multiply it you have to move it back in three after you get your solution, or else it is incorrect.
Step-by-step explanation:
At the start of his work day, Mr. Eriksen had 20 boxes of light bulbs tested and ready to be shipped. On average, he can test 40 boxes of light bulbs each hour. Of the 40 boxes tested each hour, he sets aside 5 boxes for retesting. The remaining boxes are marked as ready to be shipped.
A: Mr. Eriksen's situation can be represented by a linear function. Identify the rate of change and initial value of this function. Explain what these values represent in terms of the situation.
B: Write an equation in slope-intercept form to represent the situation. Use x for the independent variable and y for the dependent variable. Identify what both variables represent.
Answer:
See belowStep-by-step explanation:
Initial value is 20 as there are already 20 boxes ready for shipment.
Each hour 40 - 5 = 35 boxes are ready for shipment
The linear function for this case is:
y = 35x + 2035 is the slope or rate of change, 20 is the y-intercept.
y- the number of boxes ready for shipment after x hours.

Given g(x)=-2x-1g(x)=−2x−1, find g(-4)g(−4)
Answer:
7
Step-by-step explanation:
The function f is defined by g(x) = -2x-1. so the function defined as g (-4) will be equal to g (-4) = 7.
What is a function?Function is a type of relation, or rule, that maps one input to specific single output.
The function f is defined by g(x)=−2x−1
We need to find the function defined as g(-4).
Then substitute;
g(x)=−2x−1
g(-4 ) =−2 (-4) − 1
g(-4 ) = 8 -1
g(-4 ) = 7
Therefore, The function f is defined by g(x) = -2x-1. so the function defined as g (-4) will be equal to g (-4) = 7.

| x/3 | = 3 Absolute Value Equations if someone could please explain to me how to do this it would be much appreciated.
Answer:
Absolute value equations are equations where the variable is within an absolute value operator, like |x-5|=9. The challenge is that the absolute value of a number depends on the number's sign: if it's positive, it's equal to the number: |9|=9. ... So when we're dealing with a variable, we need to consider both cases.
