6 0

Answer:

0, 1, 2

Step-by-step explanation:

The solution to a system of equations given graphically is at the intersection of the individual graphs.

Graph (1)

There is no intersection between the 2 graphs so no solution

Graph (2)

There is one point of intersection between the 2 graphs so 1 solution

Graph (3)

There are two points of intersection between the 2 graphs so 2 solutions

Question 18
kobusy [5.1K]

Answer:

Undefined

Step-by-step explanation:

y=-7 has a slope of 0, since it is a horizontal line. The only types of lines that are perpendicular to horizontal lines are vertical lines, which are usually in the form x=a (where a is any real number). Vertical lines have an undefined slope, so the answer is undefined. Hope this helps!

One number is 6 times another number. it is also 12 more than twice the other number. Find the numbers.
stepan [7]

The numbers are 3 and 18

Step-by-step explanation:

  • Step 1: Let one number be x. Then the other number = 6x.

Also, 6x = 12 + 2x

⇒ 4x = 12

⇒ x = 3

⇒ 6x = 18

-8 + 5x - 2 = 20 solve
vaieri [72.5K]

Combining like terms on the left-hand side gives us 5x-10=20. Adding 10 to both sides gives 5x=30, and dividing both sides by 5 gives our answer of \boxed{x=6}.

If g(x) = 2(x − 4), find the value of x if g(x) = 20
Natalka [10]
Substitute for x.
g(20)= 2(20-4)
g(20)=32.
x=32.
