Hey there, tmwoycik0101!

The system above has one solution.
You can find this by making each equation equal to each other and solve for x
So,
3x - 7 = -2x + 4 (We add 7 to both sides)
3x = -2x + 11 (Now add 2x to both sides)
5x = 11 (Now divide by 5)
x = 2.2
So, it has one solution.

Thank you for using Brainly.
See you soon!

Suppose you have 100 ft of string to rope off a rectangular section for a bake sale at a school Fair. The function A=x^2+50x giv

Answer:

Therefore the width is 25 feet for getting maximum area.

The maximum area of the rectangle is 625 square feet.

Therefore the range is 0≤A≤625.

Step-by-step explanation:

Given function is

A = - x²+50x

We know that ,

If y = ax²+bx+c

For the maximum $x=-\frac{b}{2a}$

Here a = -1 , b= 50 and c=0

Therefore the width $x= -\frac{50}{2.(-1)} = 25$

Therefore the width is 25 feet for getting maximum area.

The maximum area =[ -(25)²+50.25] square feet

= 625 square feet

The area can not be negative and maximum area is 625 square feet.

Therefore the range is 0≤A≤625.
