Answer:
Step-by-step explanation:
<u>Given sides of a rectangle</u>
- Length: l =4 − 7(3x + 4y)
- Width: w = 3x(−2y)
<u>Perimeter of rectangle</u>
<u>Using the given values</u>
- P = 2( 4- 7(3x + 4y) + 3x(-2y)) =
- 2( 4 - 21x - 28y - 6xy) =
- 8 - 42x - 56y - 12xy
The 4th option.
The values with no x or y attached are the y intercept
6x - 7y = 21
Subtract 6x from both sides
6x - 7y - 6x = 21 - 6x
-7y = 21 - 6x
Divide both sides by - 7
-7y/-7 = 21/-7 - 6x/-7
Y = -3 +6x/7
The why intercept, -3 is the same as the one in the question
<span>The absolute value is 9.8, (example): if it was -3 (negative 3) then the absolute value would be just 3 (or positive 3). The absolute value is always positive.
Hope this helped! :)</span>
Using a system of equations, it is found that she made:
- 168 two-point field goals.
- 53 three-point field goals.
For the system, we have that:
- x is the number of free throws made.
- y is the number of two-point field goals made.
- z is the number of three-point field goals made.
She made 362 shots, hence:

She scored 636 points, hence:

- Observation: I used 636 as there would not be a solution(number of field goals cannot be a fraction) if 634 was used.
She made 27 more 2-point field goals than free throws, hence:

Then:








Equaling both equations for z, finding x:

Then, to find y and z:

She made:
- 168 two-point field goals.
- 53 three-point field goals.
