Answer:
n =-19
Step-by-step explanation:
3* (n+7) = -36
Distribute
3n+21 = -36
Subtract 21 from each side
3n+21-21 = -36-21
3n = -57
Divide by 3
3n/3 = -57/3
n =-19
Correct answer A) x+4y=8 , represents an equation of a line that has an x-intercept of 8 and a y-intercept of 2 .
<u>Step-by-step explanation:</u>
Here we have to identify Which of the following represents an equation of a line that has an x-intercept of 8 and a y-intercept of 2 .Let's find out:
A) x+4y=8
Let's check if line has an x-intercept of 8 i.e. at y=0 value of x is 8 :
⇒ 
⇒ 
⇒ 
Let's check if line has an y-intercept of 2 i.e. at x=0 value of y is 2 :
⇒ 
⇒ 
⇒ 
Hence , Correct option!
B) x=(-.25y+2)
Let's check if line has an x-intercept of 8 i.e. at y=0 value of x is 8 :
⇒ 
⇒ 
⇒ 
Incorrect option!
C) 4x+y=2
Let's check if line has an x-intercept of 8 i.e. at y=0 value of x is 8 :
⇒ 
⇒ 
⇒ 
Incorrect option!
D) y=-4x+8
Let's check if line has an x-intercept of 8 i.e. at y=0 value of x is 8 :
⇒ 
⇒ 
⇒ 
Incorrect option!
Answer: 10/-3
Step-by-step explanation: in the x it’s increasing by 3 and in The y it’s decreasing by 3 so it becomes -3 and you can not symplif 10/-3 so the answer is just 10/-3
