<u>Given Function is</u>
- f ( x ) = 7x - 7 ------- eqn ( 1 )
<u>Now , put the value of x = 8 in eqn ( 1 )</u>
- f ( 8 ) = 7 ( 8 ) - 7
- f ( 8 ) = 56 - 7
- f ( 8 ) = 49 ------- eqn ( 2 )
<u>Now , put the value of x = 4 in eqn ( 1 )</u>
- f ( 4 ) = 7 ( 4 ) - 7
- f ( 4 ) = 28 - 7
- f ( 4 ) = 21 ------- eqn ( 3 )
<h3 />
<u>From eqn ( 2 ) nd eqn ( 3 ) we get,</u>
- f ( 8 ) + f ( 4 )
- 49 + 21
- 70
Hope Helps! :)
Answer:
x = 3
Step-by-step explanation:
6x - 4 = 2x + 8
6x - 2x = 8 + 4
4x = 12
x = 12/4
x = 3
Answer:
A: 1/2 divided by 1 1/2 is 3. 1/2 divided by 1 is 2. 1/2 divided by 2 1/2 5. Multiply those numbers and you get 15 which is how many can fit. B: Idk how to answer part B but you can have part A.
Step-by-step explanation:
Length: 1 1/2. Width: 1. Height: 2 1/2. Volume: how much of ? can fit in a ?. To get the volume you multiply 1 1/2 x 2 1/2 x 1. Make the mixed numbers into improper fractions: 3/2, 5/2, 2/2. Now multiply the numerators: 5 x 3 = 15x 2 = 30. Now in order to finish it you put 2 as the denominator. : 30/2 which as a whole number is 15. 15 cubes can fit.
