First solve for y with first equation:

3y = 13-6x so y = 13/3-2x

Plug that in with 2nd equation:

-9x-4(13/3-2x)=-17

-9x-52/3-8x=-17

-17x=-34 1/3

x = <u>34 1/3 </u>
17

x = 103/51

There are a total of 84 students in a drama club and a yearbook club. The drama club has 16 more students than the yearbook club

vodomira [7]

Y = yearbook club
d = drama club

y + d = 84
d = y + 16

now we sub y + 16 in for d in the first equation
y + d = 84
y + (y + 16) = 84
2y + 16 = 84
2y = 84 - 16
2y = 68
y = 68/2
y = 34 <=== yearbook club students

d = y + 16
d = 34 + 16
d = 50 <=== drama club students

If f(x)=2x^2+5√(x-2), complete the following statement:<br><br> f(3) = _____

dsp73

Given:
$f(x) = 2x^{2} +5 \sqrt{x-2}$

Asked:
f(3)

Solution:
Subtitute x with 3 in the function
$f(x) = 2x^{2} +5 \sqrt{x-2}$
$f(3) = 2(3)^{2} +5 \sqrt{3-2}$

Then simplify to find the value of f(3)
$f(x) = 2(9) +5 \sqrt{1}$
$f(x) = 18 +5$
$f(x) = 23$

The final answer is 23
