Which of the following represents an equation of a line that has an x-intercept of 8 and a y-intercept of 2?

Julli [10]

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 .

Step-by-step explanation:

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 :

⇒ $x+4y=8$

⇒ $x+4(0)=8$

⇒ $x=8$

Let's check if line has an y-intercept of 2 i.e. at x=0 value of y is 2 :

⇒ $x+4y=8$

⇒ $0+4(y)=8$

⇒ $y=2$

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 :

⇒ $x=(-.25y+2)$

⇒ $x=(-.25(0)+2)$

⇒ $x=2$

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 :

⇒ $4x+y=2$

⇒ $4x+0=2$

⇒ $x=\frac{1}{2}$

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 :

⇒ $y=-4x+8$

⇒ $0=-4x+8$

⇒ $x=2$

Incorrect option!

Solve the following proportion for the unknown variable: 15/d = 24/40

Pavel [41]

Answer:
d = 25

Explanation:
To get the value of d, we will need to isolate the d on one side of the equation.

This can be done as follows:
 $\frac{15}{d} = \frac{24}{40}$ 

First, we will do cross multiplication as follows:
40*15 = 24*d
600 = 24d

Then, we will isolate the d as follows:
24d = 600
 $\frac{24d}{24} = \frac{600}{24}$

d = 25

Hope this helps :)
