Answer:
<u>The three true options are B, C and E.</u>
Step-by-step explanation:
Let's simplify the expression that represent the score of Javier in a game of mini-golf:
3x + x + 5 – 2x
2x + 5
Which statements are true about the parts of the simplified expression? Select three options.
A. The constant is 2.
It's false. The constant is 5.
B. The coefficient is 2.
It's true. The coefficient of x is 2.
C. The constant is 5.
It's true.
D. The coefficient is 5.
It's false. 5 is the constant and the coefficient of x is 2.
E. There are two terms.
It's true. The two terms are 2x and 5.
<u>The three true options are B, C and E.</u>
Step-by-step explanation:
x+3y=24
3y/3=24/3
x+y=8
divide x to both side not to y
y=-x +8
If we translate the word problems to mathematical equation,
2x + 3y = 60
The second equation is,
P = xy³
From the first equation, we get the value of y in terms of x.
y = (60 - 2x) / 3
Then, substitute the expression of y to the second equation,
P = x (60-2x) / 3
P = (60x - 2x²) / 3 = 20x - 2x²/3
We derive the equation and equate the derivative to zero.
dP/dx = 0 = 20 - 4x/3
The value of x from the equation is 15.
Hence, the value of x for the value of the second expression to be maximum is equal to 15.
