It should be 13 since 13+8 = 21. 21-7 = 13
Answer:
The soda costs 2.20 and the sandwich costs 7.70
Step-by-step explanation:
To find this, set the soda cost as x. We now know that the sandwich cost is 3.5x. Add these together and set equal to 9.90
x + 3.5x = 9.90
4.5x = 9.90
x = 2.20
This is the cost of the soda. Now we can multiply that by 3.5 to get the sandwich cost.
3.5 * 2.20 = 7.70
The general slope-intercept form equation is:
In this case, m=-2 and with the point (4, 10) we can find the value of b:
We found that b = 18, so:
Answer:
<h2>C. g(x) = x - 6</h2>
Step-by-step explanation:
For a parent function y = f(x) and n > 0:
f(x) + n : move the graph n units up
f(x) - n : move the graph n units down
f(x + n) : move the graph n units to the left
f(x - n) : move the graph n units to the right
===================================================
We have
f(x) = x
Transformation: 6 units down
f(x) - 6 = x - 6
Moving up would add to the Y value. Moving to the left subtracts from the X value.
The answer would be: (X,Y) — (x-3, y + 5)
