Answer:
a = 1
b = -1
Step-by-step explanation:
First, let's make equations out of those given f(x)'s
-4 = -3a + b
2 = 3a + b
We can use elimination method to get rid of the a real quick
-4 = b
2 = b
Add those together
-2 = 2b
Divide both sides by 2
-2/2 = 2b/2
b = -1
Plug in the new b in one of the original equations; I'm gonna use the bottom one
2 = 3a - 1
+ 1 + 1
3 = 3a
3/3 = 3a/3
a = 1
Answer:
This is an example of
C. simultaneous causality.
Step-by-step explanation:
Simultaneous causality eliminates the conclusion that is often taken for granted to the effect that one variable is a response variable while the other is an explanatory variable because the two variables, the price and the number of shares, influence each other at the same time. When more shares are traded than demanded in the stock market in any day, the price tends to go down, and vice versa.
We know that 
.
Solve using cross multiplication of the last two fractions. I will use 
to represent the width of the rectangle. 
Multiply. 
Divide both sides of the equation by 
. 
The average wait time is simply the averages of all the wait times in a product category. For instance, a custom watch manufacturer might have a wait time that ranges from 5 days to 10 days for a model A watch depending on the options. The average wait time for the model A watch is 7.5 days.
Answer: In the chart, put 6 in place of the question mark.
The equation should be something like w = 2/3 p
W is the number of quarts of water. P is the number of quarts of Pineapple juice.
This week they will need 3 times the previous week so 18 quarts of pineapple juice and 12 quarts of sparkling water.
Step-by-step explanation:
If the basic recipe is 2 water to 3 juice, and they used 4 quarts if water, you can see that is <u>double the amount of</u> water so you need <u>double the amount </u> of juice. 2 times 3 is 6.
<em>Unit rate</em> means for ONE quart of juice, how much sparkling water is used. that should be 1 Pineapple Juice for 2/3 Sparkling water
OR
for EACH quart of sparkling water, how much juice do you need.
that would be 1 unit of Sparkling Water for 1 1/2 units of Pineapple Juice
