Step-by-step explanation:
The domain of a graph is all of the possible x values, and the range is all possible y values.
7. The graph goes on for both the x and y values, so the domain is (-inf, inf) and the range is (-inf, inf).
8. In this case, the domain is also (-inf, inf), but the range is [-2, inf) as there are no y values less than -2.
9. The domain is [-2, 2], as the x values only range from -2 to 2. The range is [-3, 3] as the y values range from -3 to 3.
10. The domain is (-inf, inf) because all x values are possible. The range is [-1, 1], as there are no y values greater than 1 or less than -1.
6x-12
Combine 2x and 4x = 6x
Combine -17 and 5 = -12
Answer:
The length of a pencil is 4.5 inches. The length of a crayon is 2.1 inches.
Step-by-step explanation:
Let pencils be p
Let crayons be c
6 pencils and 5 crayons are 37.5 inches. This will be:
6p + 5c = 37.5 ........ equation 1
7 pencils and 6 crayons are 44.1 inches. This will be:
7p + 6c = 44.1 ........ equation 2
Multiply equation 1 by 7
Multiply equation 2 by 6
42p + 35c = 262.5 (3)
42p + 36c = 264.6 (4)
Subtract 4 from 3
c = 2.1
Plug the value of c into equation 1
From equation 1
6p + 5c = 37.5
6p + 5(2.1) = 37.5
6p + 10.5 = 37.5
6p = 37.5- 10.5
6p = 27
p = 27/6
p = 4.5
hope this helps
