Mathematics
1 answer:
Misha Larkins [42]3 years ago
4 0

Answer:

1, 2, 3

Step-by-step explanation:

X <= 20 means that x has to be less than OR equal to 20.

The first option is -100. That's less than 20, so this statement is true.

The second option is 10. That's also less than 20, so this statement is also true.

The third option is 20. This is equal to 20, so this is also true.

The fourth option is 21, which is greater than 20, so it's not true.

The fifth option is 45, which is greater than 20, so it's not true.

Sorry I answered so late, hope this helps even though you probably don't need it anymore.

Question 8(Multiple Choice Worth 1 points) (08.02 MC) Which graph best represents the solution to the following pair of equation
elena-s [515]
<span>y = −2x + 13
y = 2x − 3

</span>−2x + 13  = 2x − 3
subtract 2x on both sides
−2x + 13  −2x = 2x − 3 - 2x
simplify
-4x + 13 = -3
subtract 13 on both sides
-4x + 13 -13  = -3 - 13
simplify
-4x = -16
divide both sides by (-4)
   x = 4

substitute x = 4 into y = 2x − 3 to find y

y = 2x − 3
y = 2(4)− 3
y = 8 - 3
y = 3

answer
solution x = 4 and y = 3

hope it helps

Which of these statements is correct?
mariarad [96]

Answer:

The answer to your question is the third choice.

Step-by-step explanation:

a)          6x - 5y = 8

           12x - 10y = 16

We observe that these lines are the same so they have infinite solutions.

b)

            7x + 2y = 6

           14x + 4y = 16

These lines are parallel because they have the same slope, so they do not cross, there is no solution.

c)

             8x - 3y = 10

            16x - 6y = 22

These lines are parallel because they have the same slope, so they do not cross, there is no solution.

d)

            9x + 6y = 14

           18x + 12y = 26

These lines are parallel because they have the same slope, so they do not cross, they do not have an infinite number of solutions.
