Answer:
(x - 7)^2 + (y - 2)^2 = 5^2
Step-by-step explanation:
Center at (7, 2); radius 5
Adapt (x - h)^2 + (y - k)^2 = r^2 to this situation. Replace h by 7, k by 2 and r by 5:
(x - 7)^2 + (y - 2)^2 = 5^2
Linear functions are usually of degree 1. They are a straight line. y=mx+b
Answer:
10.8
Step-by-step explanation:
By sine rule:

Answer:
Total seashells = (6g + 10) seashells.
Step-by-step explanation:
Given that Mario collected 3g seashells.
Given that Jasmine collected 10 more seashells that mario. It means she collected (3g+10) seashells.
It says to write the number of seashells they collected together in terms of g.
Total seashells = Mario's seashells + Jasmine's seashells.
Total seashells = 3g + (3g+10).
Total seashells = 6g + 10.
Hence, Total seashells = (6g + 10) seashells.
Remark
There is no short way to do this problem and no obvious way to get the answer other that to solve each part.
Solve
A
Multiply by 2
x + 1.6 = 2(x + 0.1) Remove the brackets
x + 1.6 = 2x + 0.1*2
x + 1.6 = 2x + 0.2 Subtract x from both sides
1.6 = x + 0.2 Subtract 0.2 from both sides
1.6 - 0.2 = x
1.4 = x
Circle A
B
Subtract 2x from both sides.
3x - 2x = 1.4
Circle B
C
Remove the brackets.
4x + 6 = 2x - 6 Add 6 to both sides
4x + 12 = 2x Subtract 4x from both sides.
12 = -2x Divide by - 2
12/-2 = x
x = - 6 Don't circle C
D
I'm going to be very scant in my solution of this. You can fill in the steps.
3x = 4.2
x = 4.2/3
x = 1.4
Circle D
