The sum of a number and twice another number is 17. The sum of twice the first number and the second number is 4. What are the t
zhannawk [14.2K]

Step-by-step explanation:

Given that,

a + 2b = 17

Also,

2a + b = 4

By adding the above expressions we get,

a + 2b + 2a + b = 17 + 4

3a + 3b = 21.

3 (a + b) = 21

a + b = 21/3

a + b = 7 Let us take 'b' = 10

a + 10 = 7

a = 7 - 10

a = -3

Now let's check by verifying by putting a = -3 and b = 10 in the previous expressions

a + 2b = 17

-3 + (2 × 10) = 17

-3 + 20 = 17

17 = 17

2a + b = 4

(2 × -3) + 10 = 4

-6 + 10 = 4

4 = 4

Therefore, a = -3 and b = 10 [(-3,10)] is the solution.

The value of the expression
r-ruslan [8.4K]

Answer:

f(5) = 75

Step-by-step explanation:

The function is f(x) = 2x^2 + x(100 - 15x).

Evaluate this function at x = 5:  replace each instance of x with 5:

f(5) = 2(5)^2 + 5(100 - 15·5)

Order of operations rules require evaluating the expression enclosed in parentheses first.  We get:

f(5) = 2(5)^2 + 5(100 - 15·5)

      = 50       + (100 - 75), so that:

f(5) = 50 + 25 = 75

f(5) = 75
