Answer:

x = - 1 and x = 8.1

Step-by-step explanation:

Desmos does a remarkable job of graphing anything that has sensible critical points.

Here on this graph, the intersect points are clearly marked and the answer is that there are two answers.

(-1, -4) and (8.088, - 6.176)

Since you are only interested in the x values, the answer is

x = - 1 and x = 8.1

The answer is C

Answer:

C ≈-1 and x≈8.1

Step-by-step explanation:

-sqrt(x + 2) - 3 = 4 - 2 abs(x - 3)

Using graphing technology, (see the graph) they intersect at x≈-1 and x≈8.1

If you have 120 feet of fencing and want to enclose a rectangular area up against a long, straight wall, what is the largest are

Tems11 [23]

The area of rectangular is A= length x width

120 feet of fancing = ---------------------------------- (the above line)

!-----------------------------------------!
! !
x ! the enclosed area ! x
! !
!---------------------------------------- !
120 -(x+x)
so the area is A = (120-2x) (x)= 120x-2x²

Melons cost $20 pet Crate, and apples cost $8 per create. an order comes in for a total of 48 crates for $420. what was the numb

Alika [10]

Answer:

The number of melon was 3 and the number of apples was 45.

Step-by-step explanation:

1. Melons cost $20 per crate and apples cost $8 per create. If the total was 48 crates for $420, you can make the following system of equations, where $x$ is the number of melons and $y$ is the number of apples:

$\left \{ {{x+y=48} \atop {20x+8y=420}} \right.$

2. By applying the Method of substitution, you can solve for $y$ in the first equation and substitute it into the second one to find $x$ . Then, you can substitute the value of $x$ into the first equation to find $y$ :

$y=48-x$

$20x+8(48-x)=420\\20x+384-8x=420\\12x=36\\x=3$

$3+y=48\\y=45$

Answer:

The graph in the attached figure

The point (-1,4) represent a solution

Step-by-step explanation:

we have

$x> -2$ ----> inequality A

$y\leq 2x+7$ ----> inequality B

using a graphing tool

The solution is the shaded area

see the attached figure

Remember that

If a ordered pair is a solution of the system of inequalities, then the ordered pair must lie on the shaded area of the solution of the system of inequalities

The point (-1,4) represent a solution
