Our equation is y = 6x - 5 when simplified. In order to be parallel, the equation for the answer must also have a slope of 6x. This rules out options C and D.
Now just plug in 4 for the x-value for each one to get your answer. A little mental math and I can already tell you it's option A.
6(4) - 14 = y
24 - 14 = y
10 = y
10 = 10
Whereas for option B:
6(4) + 14 = y
24 + 14 = y
38 = y
38 ≠ 10
Option A is your answer.
Answer:
Step-by-step explanation:
The equation is:
√b+20 - √b = 5
The first step is we will add √b to both sides:
√b+20 -√b +√b = 5 +√b
√b+20 = 5+√b
Now take square at both sides:
(√b+20)^2 = (5+√b)^2
b+20 = 25+10√b+b
Now combine the like terms:
b+20-25-b=10√b
-5 = 10√b
Divide both the terms by 10
-5/10 = 10√b/10
-1/2=√b
Take square at both sides:
(-1/2)^2 = (√b)^2
1/4 = b
So in this type of question we add radical terms to both sides and square both sides twice....
Answer:

A=(a+b) h/2
Answer:
B
Step-by-step explanation:
If the dot it open, it does not include the number. If the dot is shaded, it does include the number. Whichever way the orange line is pointing, corresponds to < or >.
