Given f(x) = 3x-4 and g(x)= -2x+7 evaluate. .

-21

Step-by-step explanation:

The given functions are

We need to find the value of .

The substitute x=6 in f(x), to find the value f(6).

The substitute x=14 in g(x), to find the value g(14).

According to the composition of functions,

Substitute x=6 in the above formula.

Therefore the value of is -21.

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
