Step-by-step explanation:
sub to tapl :L
Answer:
L=(8x^2+3)/x
Step-by-step explanation:
The area of a rectangle is length time width.
A=LW
In this case,
A=32x^2+12
W=4x
Solve for L
L=A/W
Substitute
L=(32x^2+12)/4x
L=(8x^2+3)/x
So a Quadratic function,A quadratic function is one of the form f(x) = ax2 + bx + c, where a, b, and c are numbers with a not equal to zero
<h3>Answer: Choice (1)</h3>
Wayne can buy 2 walking tacos and 4 boxes of popcorn.
====================================================
Explanation:
x = number of tacos
y = number of boxes of popcorn
3x = amount spent on all the tacos only ($3 per taco)
1y = amount spent on all the popcorn only ($1 per box of popcorn)
3x+1y = total amount spent for both food types combined
3x+1y = 10 since Wayne has $10 to spend
The equation solves to y = 10-3x
------------------
If we plugged in x = 2, then,
y = 10-3x
y = 10-3*2
y = 10-6
y = 4
Telling us that x = 2 and y = 4 pair up together. The point (2,4) is on the line y = 10-3x
Since x is the number of tacos and y is the amount of popcorn, this means (x,y) = (2,4) indicates that:
Wayne can buy 2 tacos and 4 boxes of popcorn
This is why the answer is choice (1).
Choice (2) is incorrect because it has the numbers swapped in the wrong spots.
