Answer:

(-5, 3)

Step-by-step explanation:

Elimination seems like the best method to use here.

x+y=-2

x-y=-8

---------

2x=-10

Divide everything by two

x=-5

Now plug it back into one of the original equations,

-5+y=-2

Add 5 to everything

y=3

Answer:

The solution is (-5, 3).

Step-by-step explanation:

If you have been told to solve this system of linear equations, start out by adding them together.  The y terms then drop out, and we obtain:

2x = -10, implying that x = -5.

Selecting the first equation as our starting point in finding y:

-5 + y = -2.

We need to isolate y.  To do this, add 5 to both sides:

y = -2 + 5, or y = 3.

Then the solution is (-5, 3).

The closer the slope value is to zero, the steeper the line. yes or no
Harrizon [31]
No, that is not true. Use the website desmos.com to try it out yourself. Graph equations like y=1x, y=1/2x, and y=1/4x to try. Then, you will see that as the number gets bigger, the line gets steeper (it gets higher..like a hill..rising..)

The function h ( x ) = 1 x − 1 h ( x ) = 1 x - 1 can be expressed in the form f ( g ( x ) ) f ( g ( x ) ) , where g ( x ) = ( x
Radda [10]

Answer: f(x) = 1^(x + 1)

Step-by-step explanation:

we have that h(x) = 1^x

and h(x) = f(g(x))

This mean that we are evaluating the function f(y) in the point y = g(x)

where g(x) = x - 1

then:

f(g(x) = f(x - 1) = h(x) = 1^x

then we should have that:

f(x) = 1^(x + 1)

then:

f(x - 1) = 1^(x - 1 + 1) = 1^x
