the third set represent a function

For the points to represent a function then for each value of x there can only be one corresponding value of y

sets 1, 2 and 4 do not obey this and have more than one value of y for a given x

set 1

1 → 1, 2, 3, 4, 5

set 2

3 → 3, - 3 and 5 → 5, - 5

set 4

- 1 → - 1, 1 and - 2 → 4, - 4

vfiekz [6]

Answer:

three and one fourth + 2x ≥ 6

Step-by-step explanation:

Let

x -----> the minimum number of hours he needs to practice on each of the two days

we know that

needs to spend at least seven hours each week practicing the drums

$3\frac{1}{4}+2x\geq 6\ hours$

Convert mixed number to an improper fraction

$3\frac{1}{4}\ hours=\frac{3*4+1}{4}=\frac{13}{4}\ hours$

substitute

$\frac{13}{4}+2x\geq 6\ hours$

Subtract 13/4 both sides

$2x\geq 6-\frac{13}{4}$

$2x\geq \frac{11}{4}$

Divide by 2 both sides

$x\geq \frac{11}{8}$

therefore

The minimum number of hours he needs to practice on each of the two days is $\frac{11}{8}\ hours$

W=2j, m=5w, (m+4)=6(j+4)

using w from first in second you get:

m=5(2j)=10j, m+4=6j+24

m=10j, m=6j+20, since m=m we can say

10j=6j+20

4j=20

j=5, and since m=10j

m=50

So the man is 50 years old

Circumference = 12.6yds find the radius.

Studentka2010 [4]

Circumference= 2 times pi times radius
c=2pir
divide both sides by 2pi
c/(2pi)=r
c=12.6
12.6/(2 times pi)=12.6/2 times 1/pi=6.3 times 1/pi=6.3/pi

radius=6.3/pi=aprox (pi aprox 3.14) 2
