<h2>Answer:-</h2>

$\pink{\bigstar}$ The larger number is $\large\leadsto\boxed{\tt\purple{78}}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

<h3>• Given:-</h3>

Sum of two numbers is 100.

Difference between the numbers is 56.

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

The larger number = ?

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

<h3>• Solution:-</h3>

Let the two numbers be 'x' and 'y' respectively.

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

According to the question:-

✯ Sum of two numbers is 100.

➪ $\sf x + y = 100 \dashrightarrow\bold\red{[equation \: 1]}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Also,

✯ Difference between the numbers is 56.

➪ $\sf x - y = 100 \dashrightarrow\bold\red{[equation \: 2]}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

• Adding equation [1] and equation [2]:-

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

➪ $\sf (x + y) + (x - y) = 100 + 56$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

➪ $\sf x + y + x - y = 156$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

➪ $\sf 2x = 156$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

➪ $\sf x = \dfrac{156}{2}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

★ $\large{\bold\red{x = 78}}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

• Substituting the value of x in equation [1]:-

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

➪ $\sf x + y = 100$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

➪ $\sf 78 + y = 100$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

➪ $\sf y = 100 - 78$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

★ $\large{\bold\red{y = 22}}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Therefore, the numbers are 78 and 22.

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

The larger number is 78.

Find y for x=0,1,2, and 3. y=4-x

LenKa [72]

4 - (0) = y
4 - 0 = 4 y = 4

4 - (1) = y
4 - 1 = 3 y = 3

4 - (2) = y
4 - 2 = 2 y = 2

4 - (3) = y
4 - 3 = 1 y = 1

PLEASE HELP IM SO STUCK

Gennadij [26K]

Answer:

-4

Step-by-step explanation:

Slope = y/x

1. y=12 x=-3

12/-3=-4

2. y=8, x=-2

8/-2 = -4

3. y=4, x=-1

4/-1 = -4

4. 0/0 = 0

5. y=-4, x=1

-4/1 = -4

Hope it helps I had this question last year on Acellus.
