The change in the sign of the x coordinate transformed and no change in value of y coordinate shows transformation with y axis.
We need the exact value of
to find a proper solution, but a general one can still be found. Subtracting the first equation from the second gives
Plug this into either equation and you get
(It's guaranteed that
in this case because that already corresponds to
.)
The given question is incomplete
Here are some letters and what they represent. All costs are in dollars.
m represents the cost of a main dish.
n represents the number of side dishes.
s represents the cost of a side dish.
t represents the total cost of a meal.
Discuss with a partner: What does each equation mean in this situation? a. a. m = 7.50
b. m = s + 4.50
c . ns = 6
d. m + ns = t
2. Write a new equation that could be true in this situation.
Answer:
t = 3m -n(s+1)
Step-by-step explanation:
Using the information we can describe the value of each letters
using a and b
7.50 = s + 4.50
s = 3
substitute s in c, we get
using equation d we have
- m + ns = t
- 7.50 + 6 = t
- t = 13.50
so we an equation using the above data
t +ns = 3m - n
t = 3m -n(s+1)
Answer:
Step-by-step explanation:
I'm not sure I know exactly what that [1] means.
But here's how you get the answer
g(x) = 3x + 12
The symbolism means that wherever you see an x on the right side of g(x) you put f(x)
So it looks like this
g(f(x) ) = 3(f(x)) + 12 Now you put f(x) = 2x + 7 in for f(x) on the right.
g(f(x)) = 3(2x + 7) + 12 Remove the brackets
g(f(x)) = 6x + 21 + 12
g(f(x)) = 6x + 33
Now you deal with the x on the left. It becomes - 6
g(f(-6)) = 6(-6) + 33
g(f(-6)) = -36 + 33
g(f(-6)) = - 3
Rule 1
(g · f)(x)
has the meaning of whatever the function on the left is (in this case g) then the function of f is put in the xs place.

Answer with explanation:</h2><h2>
</h2>
Let p be the population proportion of orders are delivered within 10 minutes of the time the order is placed.
Then according to the claim we have ,
Since the alternative hypothesis is two-tailed so the hypothesis test is a two-tailed test.
For sample ,
n = 90
Proportion of orders are delivered within 10 minutes of the time the order is placed=
Test statistics for population proportion :-
The p-value : 
[By using standard normal distribution table]
Since the p-value is greater that the significance level (0.01), so we do not reject the null hypothesis.
Hence, we conclude that we have enough evidence to support the claim that 90% of its orders are delivered within 10 minutes of the time the order is placed.
