Answer:

The number is 35

Step-by-step explanation:

Let x be the number

1/5 x + 3x

=

2x + 42                 Break the question into phrases and solve 1 phrase at a time.

1/5 = 0.2

0.2x + 3x = 2x + 42              Combine the left

3.2x = 2x + 42                       Subtract 2x from both sides

3.2x - 2x = 42                        Combine

1.2x = 42                                Divide by 1.2

x = 42/1.2

x = 35

What is the range of the function y=2x+1 for the domain 2<=x<=5?
egoroff_w [7]
So domain is the number you can use
range is the output your get from inputting the domain given
so from 2≤x≤5
since it is linear, we can be sure that we only need to test the endpoints of the domain to find the endpoints of the range

sub 2 for x
y=2(2)+1
y=4+1
y=5

sub 5 for x
y=2(5)+1
y=10+1
y=11

so range is from 5 to 11
in interval notation: [5,11]
in other notation 5≤y≤11
or
R={y|5≤y≤11}
