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 .

<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 :

⇒ $x+4y=8$

⇒ $x+4(0)=8$

⇒ $x=8$

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!

Anika [276]

Answer:

amount = 407 per month

Step-by-step explanation:

given data

future value = $5000

interest rate = 6% = $\frac{0.06}{4}$ = 0.015

time = 12 months = 4 compound per year

solution

we use here formula that is

amount = future value × $\frac{r}{(1+r)^t-1}$ .......................1

put here value and we get

amount = 5000 × $\frac{0.015}{(1+0.015)^{4}-1}$

amount = 1222 per quarter

or amount = 407 per month

Rewrite each of the following statements in the form "∀ _____ x, _____." (a) All dinosaurs are extinct. ∀ x, . (b) Every real nu

jasenka [17]

Answer:

See below

Step-by-step explanation:

Essentially, we have to replace "quantifier words" like "All", "Every" by the universal quantifier ∀.

a) ∀ dinosaur x, x is extinct.

b) ∀ real number x, x is positive, negative, or zero.

c) ∀ irrational number x, x is not an integer.

d) ∀ logician x, x is not lazy.

e) ∀ integer x, x²≠ 2,147,581,953.

f) ∀ real number x, x²≠ -1.

In a) and b) we replace the words without major changes. In the other statements, we modify the statement using negation. For example, "No irrational numbers are integers." is equivalent to "Every irrational number is not integer".

MARK AS BRAINLIEST PLZZZ

Answer:

Son + Daughter 60%

Son - 23,625

Daughter - 16,875

Wife % - 40%

Total - 67,500

Step-by-step explanation:

1. We do 35 + 25 to get 60

2. 27000 / 40 to get 1% = 625

Then, 625 x 35 = 23,625

3. 625 x 25 = 16,875

4. 100 - 60 ( kids ) = 40%

5. 40500 ( kids ) + 27000 = 67, 500
