Answer:
x=4
Step-by-step explanation:
Let's solve your equation step-by-step.
−x=2−3x+6
Step 1: Simplify both sides of the equation.
−x=2−3x+6
−x=2+−3x+6
−x=(−3x)+(2+6)(Combine Like Terms)
−x=−3x+8
−x=−3x+8
Step 2: Add 3x to both sides.
−x+3x=−3x+8+3x
2x=8
Step 3: Divide both sides by 2.
2x/2 = 8/2
x=4
Answer:
F(n) = 8.5*n yards, where n is the number of windows
Step-by-step explanation:
Suppose the house of Stephen's aunt has n windows.
Since he needs 8.5 yards of fabric for each window, then he needs 8.5 times n yards of fabric for the n windows.
Call F(n) the yards of fabric he needs for the n windows, then
F(n) = 8.5*n
For example, if auntie's house had 4 windows, then
F(4) = 8.5*4 = 34 yards.
If auntie's house had 6 windows
F(6) = 51 yards.
I'm going to assume you want to find the third side of a triangle. We can use the pythagorean theorem to solve; a^2 + b^2 = c^2
a = 5
b = 3
c = ?
Solve.
5^2 + 3^2 = c^2
25 + 9 = c^2
34 = c^2
√34 = √c^2
5.8 ≈ c
Best of Luck!
Are you asking for it being simplified?
Hey there!
f(x) = 2x^2 + 1
y = 2x^2 + 1
y = 2(3)^2 + 1
3^2
= 3 * 3
= 9
y = 2(9) + 1
2(9) = 18
y = 18 + 1
y = 19
Answer: y = 19
Good luck on your assignment and enjoy your day!
