Sin = opposite/hypotenuse, so one side is 7 and the other is 8.
sqrt(64-49)=sqrt(15) which is the third side, and tangeant = opposite/adjacent, which is 7/sqrt(15). Cotangeant is 1/tangeant, so it would be sqrt(15)/7
The answer is C because 2, 5, 23, and 29 are prime numbers (you can also look up a chart and highlighted numbers are prime). prime numbers is a whole number greater than 1 and cannot be formed when multiplying two smaller numbers that are whole. it must involve itself in a multiplication equation.
Answer:
x = 4, y = -3
Step-by-step explanation:
{2x - y = 11
{x + 3y = -5
You can use the substitution method by solving for x in the second equation:
x + 3y = -5
Subtract 3y from both sides:
x = -3y - 5
Now, substitute this value for x into the first equation:
2x - y = 11
2(-3y - 5) - y = 11
Distribute:
-6y - 10 - y = 11
Add 10 to both sides:
-6y - y = 21
Combine like terms:
-7y = 21
Divide both sides by -7:
<u>y = -3</u>
Next, substitute this value for x into the second equation:
x + 3y = -5
x + 3(-3) = -5
Multiply:
x - 9 = -5
Add 9 to both sides:
<u>x = 4</u>
Answer:
Step-by-step explanation:
y + 6 = 12(x - 7)
y + 6 = 12x - 84
y = 12x - 90
Answer:
(x+3)^2+(y-5)^2=16
