Answer:
The required solution is (0.128,13.82)
Step-by-step explanation:
Consider the provided system of equation.
......(1)
......(2)
We need to solve the system of equation by substitution method.
Consider the equation 1.
......(3)
Substitute the value of y in equation 2.






Now substitute the value of x in equation 3.
Hence, the required solution is (0.128, 13.82)
Answer:
stretched by a factor of 2, reflected over the y-axis, and translated 9 units left
Step-by-step explanation:
The given function is 
We can rewrite this function by factoring -4 in the radicand to get:

We further simplify the square root of 4 to get:

The parent function is 
When we compare to the parent function, there is a stretch by a factor of 2, reflection over the y-axis, and translation 9 units left
The last option is correct
Answer:
x + 7
Step-by-step explanation:
N/A
Answer:
1
Step-by-step explanation:
So for this type of problem we use the formula
with each variable (besides m which is slope) representing a different coordinate. (e.g. -3 could be
in this case.) First, let's define which is which:
(3,2): 
(-2,-3): 
Now we need to replace the variables with their known values: 
Next, let's do the subtraction to simplify: 
And we can complete the division (all fractions are division!) to simplify even further: 
Therefore, the slope of the line passing through the points (3,2) and (-2,-3) is 1.
Answer:
94 pizzas will be sold
Step-by-step explanation:
We have to use the equation and replace 15 with x.
x=15
y=3.4x + 43
y=3.4(15) + 43
y=51 + 43
y=94
(15,94)
There will be 94 pizzas sold nightly if 15 coupons were issued.
