Answer:

-4 is a solution

Step-by-step explanation:

x = -4

Equation:

5 + 3x = -7

Substitute x for -4

New equation:

5 + 3 x -4 = -7

Solve:

3 x -4 = -12

5 + -12 = -7

-7 = -7

What is the value of g(0)<br> -2<br> -1<br> 3<br> 6
Tanzania [10]

Answer:

Step-by-step explanation:

An x value of 0 can only be plugged into the equation that has a domain that includes 0. The first function's domain is between -2 and -4, so 0 is not included in that domain. In the third function, the domain is between 1 and 3, so 0 is not included in that domain, either. The middle function's domain does include 0 (0 falls between -2 and 1) so we can only evaluate this function at an x value of 0.

g(0) = -0 - 1 so

g(0) = -1

if we increased one side of a square by 5 units and decreased the other by 3 units the area of the resulting rectangle would be
zvonat [6]

Answer:

18 units

Step-by-step explanation:

So let's list out the sides.

for the first square let's just call them x

for the second square then they would be x+5 and x-3

So let's write out their areas we will cal the area of the first one z

x*x = z

(x+5)*(x-3) = z+21

since z = x^2 we can set up the second equation as a quadratic.

(x+5)*(x-3) = x^2 + 21

x^2 - 3x + 5x - 15 = x^2 + 21

But look, the x^2s cancel out

2x - 15 = 21

2x = 36

x = 18

Test it out and see if it fits the description, And if you don't understand anything just let me know so I can explain more.
