<em>All real numbers</em>

<h2>Explanation:</h2>

Here we have the following constant function:

f(x)=5

A constant function is that given by the form:

f(x)=c \\ \\ c:A \ real \ number

So this means we will have a line that passes through the y-values c and is parallel to the x-axis. For this type of functions the domain is:

<em>All real numbers</em>

Solve this system of equations using the substitution method<br>y=x+7<br>-2x-11=y​
ryzh [129]

Answer:

x=-6, y=1

Step-by-step explanation:

Let's solve your system by substitution.

y=x+7;−2x−11=y

Step: Solve y=x+7 for y:

y=x+7

Step: Substitute x+7 for y in −2x−11=y:

−2x−11=y

−2x−11=x+7

−2x−11+−x=x+7+−x(Add -x to both sides)

−3x−11=7

−3x−11+11=7+11(Add 11 to both sides)

−3x=18

−3x/ −3 = 18/ −3  (Divide both sides by -3)

x=−6

Step: Substitute−6 for x in y=x+7:

y=x+7

y=−6+7

y=1  (Simplify both sides of the equation)

Answer:

x=−6 and y=1

What is -4x+y=6 and -5x-y=21 in subsitution
kifflom [539]
Solve for y in the first equation.
y = 4x + 6
Substitute <span>4x + 6 into the second equation.
-5x - (</span><span>4x + 6) = 21
Distribute
-5x - 4x - 6 = 21
Combine like terms 
-9x = 27
Divide both sides by -9
x = -3
Substitute back into first equation
-4(-3) + y = 6
Solve for y
y = -6</span>
