State whether every point on the graph is a solution of the equation. Explain why or why not. x – 4y = –4 A. Every point shown o
PtichkaEL [24]
B!

The equation x-4y= -4 is the graph, right? So that means when x is, lets say, 2, then:

2-4y= -4

Simplify
-4y=-6
y=3/2

Now if you think about it, if you plug in any number for x and get some value of y, that is the point on the graph at that x value.

Hope this helps!

Natali [406]

Answer:

probability that their average salary is more than $77,500 is 0.1587

Step-by-step explanation:

standard error

= 10,000/sqrt(16)

=10,000/4

= 2500 

(77,500 - 75000)/2500

2,500/2500

= 1 

p (z > 1) = .1587

So, the probability that their average salary is more than $77,500 is 0.1587

Use a form of the distributive property to rewrite the given algebraic expression without parentheses. 2(3x-3)
guajiro [1.7K]

Answer:

6x-6

Step-by-step explanation:

The Distributive property says that a(b+c) = ab+ac

In my example you distribute the value on the outside to the things on the inside

In your problem you have a two on the outside that needs to be distributed to a 3x and a -3

1) 2 multiplied by 3x equals 6x giving you the first part of your answer!

2) 2 multiplied by -3 equals -6 giving you the second part of your answer!

Don't forget that there is a - sign between the 3x and 3, don't drop it!

Put the two values together to get 6x-6

Let me know if you have any further questions :)
