Answer: 5705 Footballs
Step-by-step explanation: Just subtract 11,795 by 4,150 to get the missing variable.
Answer: $250
Step-by-step explanation: To calculate the past year`s tax, divide this year tax to 1.15.
$ = 287.50 / 1.15 = 250
First, add 1 on both sides of the equation to begin to isolate x
x/5 = 8
Now, to isolate x, multiply both sides of the equation by 5/1

·

=

= x
x= 7 · 5/1 = 7 · 5 = 35
x = 35
Answer:
-147
Step-by-step explanation:
(21) • (-7)
Since it’s a positive times a negative, the answer will be negative
-147

<h3>
Step-by-step explanation:</h3>
This is easily solved using a graphing calculator. (See attached.)
_____
Algebraically, the solution is found by equating the expressions for y:
... -2x +7 = y = 2x² +3x -5
... 2x² +5x -12 = 0 . . . . rearranged to standard form
... (2x -3)(x +4) = 0 . . . . factor
The x-values of the points of intersection are those that make these factors be zero:
... 2x-3 = 0 ⇒ x = 3/2
... x+4 = 0 ⇒ x = -4
The linear equation is the easiest to use to find the corresponding y-values.
... for x = 3/2, y = -2(3/2) +7 = 4
... for x = -4, y = -2(-4) +7 = 15
The points of intersection are (-4, 15) and (3/2, 4).
