1. 3y=27
2. x-4=3
3. p+8=17
4. 1/2q=14
Answer:
y = 2x + 11
Step-by-step explanation:
The point slope formula for a line is
y - y1 = m(x - x1)
We already have the slope, 2, and we can substitute the point (-4, 3) into (x1, y1):
y - 3 = 2(x + 4)
y - 3 = 2x + 8
y = 2x + 11
Pi = 3. Area of a circle = pi×r squared.
R is radius, and the radius of that circle is 11 m. therefore, 3.14×11 squared will give you your answer. Don't forget, exponent before multiplication
11^2 = 121
121×3 = 363 That's the area of the big circle.
Now, 11÷2 gives you the radius of the small circles. you get 4.5
4.5^2 = 20.25
20.25*3 = 60.75
That's the area of ONE small circle. double it and you have the area of 2.
60.75×2= 121.5
Now just subtract the area of the small ones from the area of the big one to find the area of the shaded region.
363-121.5= 241.5
Now, you're done!
I don’t see the question sorry
Multiply both sides by (3*5)
5(2n)=3(n+14)
distribute
10n=3n+42
minus 3n both sides
7n=42
divide both sides by 7
n=6
