Answer:
35
Step-by-step explanation:
x=3x-70
because corresponding angles are congruent
Solve the equation to find x.
Dear Amyrandy2002, the answer to your question is 8 deli sandwiches. Since each pound of turkey makes 4 sandwiches, and two pounds of turkey are used, multiply 2 by 4 to get 8 deli sandwiches.
Answer:
Approximately what will be saved will be 8.00
Step-by-step explanation:
Here, we want to know the amount that the customer will save
Firstly, we need to know the amount that all will cost
Mathematically, that will be;
24 + 16.12 + 10.5 = 50.62
The amount to be discounted is 15% of this
That will be 15% of 50.62
= 15/100 * 50.62
= 7.593
Answer: 11.2x -9.6
Step-by-step explanation:
7.2(x + 3) + 4(x - 3) - 12 - 7.2* (x + 3) + + 4*(x - 3) then
7.2x + 21.6 + 4x - 12 - Combining like terms 7.2x+ 4x and numbers + 21.6- 12
7.2x + 4x +21.6 -12 Then we have
11.2x -9.6
Answer:
f(-3) = -20
Step-by-step explanation:
We observe that the given x-values are 3 units apart, and that the x-value we're concerned with is also 3 units from the first of those given. So, a simple way to work this is to consider the sequence for x = 6, 3, 0, -3. The corresponding sequence of f(x) values is ...
34, 10, -8, ?
The first differences of these numbers are ...
10 -34 = -24
-8 -10 = -18
And the second difference is ...
-18 -(-24) = 6
For a quadratic function, second differences are constant. This means the next first-difference will be ...
? -(-8) = -18 +6
? = -12 -8 = -20
The value of the function at x=-3 is -20.

The attachment shows using a graphing calculator to do a quadratic regression on the given points. The graph can then be used to find the point of interest. There are algebraic ways to do this, too, but they are somewhat more complicated than the 5 addition/subtraction operations we needed to find the solution. (Had the required x-value been different, we might have chosen a different approach.)
