What is the value of the variable? 3(x- 2)=15

STatiana [176]

Answer:

x=7

Step-by-step explanation:

To solve for x, you have to multiply the terms in parenthesis by 3. Then you add 6 to each side of the equal sign. Then you divide each side of the equal sign by 3 to get x=7

$3x-6=15\\3x=15+6\\3x=21\\x=21/3\\x=7$

Given the functions h(x) = 1/2x + 3 and j(x) = |x|, which value of x makes h(x) = j(x)?

Andrews [41]

Answer:

(1) or A or whatever lol

Step-by-step explanation:

basically just plug the number in, set them equal to each other, and see if the equation is true...

1/2(-2)+3=|-2|

-1+3=2

2=2

1/2(2)+3=|2|

1+3=2

4=2

1/2(3)+3=|3|

1.5+3=3

4.5=3

1/2(-6)+3=|-6|

-3+3=6

0=6

the only one that is a true statement is x=-2

Answer:

No.

Step-by-step explanation:

$x$ and $y$ could be irrational and $x+y$ be rational.

Let $x=\sqrt{2}$ and $y=-\sqrt{2}$ .

And $x+y=\sqrt{2}+-\sqrt{2}=0$ and 0 is rational.
