the IF has simply to do with not making the fraction undefined, that'd happen if it its denominator ever becomes 0, we can always check that with say y + 2 = 0, y = -2.

so that results holds true only IF "y" is never -2, because if "y" becomes -2, we'd have a denominator of (-2) + 2 = 0 and the fraction will become undefined, which you can write y ≠ -2, or -2 < y < -2.

What are the coordinates (x, y) at which the graphs of 2x + 3y = 12 and 2x - y = 4 intersect?

Jobisdone [24]

The coordinates (x,y) are (3,2), If the graphs of $2x+3y=12$ and $2x-y=4$ are intersect.

Step-by-step explanation:

The given is,

$2x+3y=12$ .................................(1)

$2x-y=4$ ....................................(2)

Step:1

The values of x and y are obtained by elimination method,

Substrate the equation (1) and (2),

$2x+3y=12$

$2x-y=4$

( - )

Equation becomes,

$(2x-2x)+(3y+y)=(12-4)$

$(0)+(4y)=(8)$

$4y=8$

$y=\frac{8}{4}$

$y=2$

From the equation (1),

$2x+3y=12$

$2x+3(2)=12$

$2x+6=12$

$2x=12-6$

$x=\frac{6}{2}$

$x=3$

Step:2

Check for solution,

$2x-y=4$ ....................................(2)

Substitute the values of x = 3 and y = 2 in above equation,

$2(3)-2=4$

$6-2=4$

$4=4$

Both sides are equal, so the x = 3 and y = 2 is correct answer

Result:

The coordinates (x,y) are (3,2), If the graphs of $2x+3y=12$ and $2x-y=4$ are intersect.

2(4.r + 3) = 7x+5<br><br> (SHOW WORK)

KatRina [158]

Answer: r=7x-1/8

Step-by-step explanation:

2(4r+3)=7x/2+5/2

4r+3=7x+5/2

4r+3-3=7x+5/2 -3

4r=7x+5/2 -3

4r/4= 7x-5/2/4 -3/4

r=7x-1/8

The chef at a steakhouse has 350 pounds of sirloin steak on hand for Saturday night. If each portion is 10 ounces, how many sirl

GenaCL600 [577]

Answer:

560 dinners

Step-by-step explanation:

First, find the amount of ounces by multiplying 350 pounds by 16 since every one pound is 16 ounces. 350×16=5600. That means there are 5600 ounces of meat. Therefore, to find the amount of steaks that can be served, divide 5600 divided by 10. 5600÷10=560.
