Answer: B. k=d+3

k-2=4(d-2)

Step-by-step explanation:

Let k be Kevin’s age and let d be Daniel’s age.

Given : Kevin is 3 years older than Daniel.

i.e. k=d+3

Kevin's age two years ago= k-2

Two years ago, Kevin was 4 times as old as Daniel.

i.e. k-2=4(d-2)

Hence, the system of equations represents this situation :

k=d+3

k-2=4(d-2)

7. Find the distance between the points (13, 8) and (-12, 6)

Alik [6]

9514 1404 393

Answer:

√629 ≈ 25.08

Step-by-step explanation:

The distance formula is useful for this.

d = √((x2 -x1)² +(y2 -y1)²)

d = √((-12 -13)² +(6 -8)²) = √(625 +4) = √629 ≈ 25.08

The distance between the points is about 25.08 units.

The difference between the squares of two consecutive numbers is 23. what are the two numbers?

Ksju [112]

(x+1)^2-x^2=23

x^2+2x+1-x^2=23

2x+1=23

2x=22

x=11

11^2 = 121

x+1 =12

12^2=144

144-121 = 23
