Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = -2x + 3
g(x) = 2x + 3
f(3) is x = 3 for function f(x)
g(7) is x = 7 for function g(x)
<u>Step 2: Solve</u>
- Substitute in <em>x</em> [Functions]: f(3) = -2(3) + 3, g(7) = 2(7) + 3
- Substitute in functions: f(3) + g(7) = -2(3) + 3 + 2(7) + 3
- Multiply: f(3) + g(7) = -6 + 3 + 14 + 3
- Add: f(3) + g(7) = -3 + 14 + 3
- Add: f(3) + g(7) = 14
Answer:
The correct answer is option C.
Sin 45 degrees = square root of 2 divided by 2, cos 45 degrees = square root of 2 divided by 2, tan 45 degrees = 1
Step-by-step explanation:
The sin cos tan table used to calculate values of the ratios for different angles can be used for the values.
The table is easily available on the internet.
WE can use a a right-angles isosceles triangle to find the exact values for the angle 45.
The equal sides have length 1. So the thirs side using the pythagoras theorem will be √2.
So
Sin 45 = √2/2
Cos 45 = √2/2
and
Tan 45 = 1
So the correct option is C.

Answer: 2(7x + 3y + 4) [unsimplified] or 14x + 6y + 8 [simplified]
Step-by-step explanation: The perimeter of a parallelogram is 2 * (the two sides.)
Adding 5x + 4 and 2x + 3y, we get 7x + 3y + 4 by combining like terms in the x terms.
Now, we multiply by 2. This is 2(7x + 3y + 4) or 14x + 6y + 8
