4x^2+4y^2=64<br> what are the domain and range
marissa [1.9K]
Use a graphing tool and you'll see a circle form. This circle has a center of (0,0) and radius of 4. Side note: this equation is equivalent to x^2+y^2 = 16 after you divide everything by 4

Looking at the graph, the smallest x can be is -4. The largest x can be is 4. So the domain in interval notation is [-4,4]

Similarly the range in interval notation is also <span>[-4,4] because the lowest you can go is y = -4. The highest you can go is y = 4</span>

3p + 4q = 22<br> 10p + 12 q = 68<br> What is p and what is q<br> (Similtaneous equations)
Rashid [163]

Answer:

q=4

p=2

Step-by-step explanation:

3p+2q=14

10p+6q=44

10(3p+2q=14)

3(10p+6q=44)

30p+20q=140-

30p+18q=132

2q=8

2q/2=8/2

q=4

3p+2*4=14

3p+8=14

3p=14-8

3p/3=6/3

p=2

hope this helps
