Answer:
Following are the answer to this question:
Step-by-step explanation:
For calculating, matching, or arranging certain fractions, the benchmark fraction can be described as common fractions, that can be calculated or judged. It is most useful when measuring fractions to comparisons in a number line.
Given value:
We are given the points
<span>(0,-4),(1,0),(2,2)
The standard form a quadratic function (in terms of x) is
y = Ax2 + Bx + C
Subsitute the points
-4 = 0 + 0 + C
C = -4
0 = A + B - 4
2 = 4A + 2B - 4
Solve for A and B
A = -1
B = 5
The function is
y = -x2 + 5x - 4</span>

Step-by-step explanation:
Answer:
Option C) 1.06[7t + 0.75(15)]
Step-by-step explanation:
Lets analyse the given information and 'build-up' our equation step-by-step.
Each plant costs $7 dollars, and Stephani will be buying a few plants. So we can name the number of plants as , therefore we have our first term of our general expression ( ) as:
Stephanie will buy one shovel that costs $15 dollars, thus our expression now becomes:
Now she will be using a coupon of 25% off the cost of the shovel. Therefore the actual cost Stephanie will be paying is % %. Thus our expression will be
Finally we know there is a Sales Tax of % which is equivalent to . Now considering you have a general amount , the Sales Tax is applied as follow: . Similarly then in our case and with the sales tax applied we have:
Thus the correct option is Option C. 1.06[7t + 0.75(15)]
