Answer:
195
Step-by-step explanation:
What is the rule? It will be easier to put this equation into a graphing calculator because it shows the table for this equation.
The answer is D. 3x^2 + 4x + 1
( since it is the only one with 3 terms )
1. Consider y=f(x)
2. let a and b be 2 positive numbers
3. then the graph of y=f(x)-a is the graph of y=f(x) shifted a units down
4. the graph of y=f(x+b) is y=f(x) shifted b units left
y=f(x-b) is y=f(x) shifted b units right
5. y=f(x+b)-a is the graph of y=f(x) shifted a units down and b units left
6. So
shifted 4 units down and 5 units left is the graph of
7. To check: consider
at x=3. We have the point (3, 27)
Shift this point 4 units down and 5 units left: (3-5, 27-4)=(-2, 23)
Consider
for x=-2
Answer:
Take the original price and divide it by .75.
Step-by-step explanation:
If he cost today is $25, which is the result of a 75% sale, this represents 1/4 of the original price. 1/4 is equal to .25. Take the original prices, and divide by .25.
One example is if the sneakers are $25 today, what was the original price?
$25/.25 = $100
Proof:
100 - (100 * 75%) = 100 - 75 = $25.00
Hope this helps! Have an Awesome Day!! :-)
