- All angles in a triangle add up to 180°
Step-by-step explanation:
<u>Step 1: Define</u>
3(x + 7)° = 63°
3(x + 7)° + 63° + y° = 180°
<u>Step 2: Solve for </u><em><u>x</u></em>
- Divide 3 on both sides: x + 7 = 21
- Subtract 7 on both sides: x = 14
Answer:
(4,-3)
Step-by-step explanation:
If the line passes through a point, the coordinates of the point will verify the equation of the line.
So, let's see if each of the coordinates verifies the equation 3x - 2y = 6
A. (4,-3) means x=4 and y = -3
so 3x - 2y becomes 3(4) - 2(-3) = 12 - -6 = 12 + 6 = 18
B. (4/3, -1) means x = 4/3 and y = -1
so 3x - 2y becomes 3(4/3) - 2(-1) = 4 - -2 = 4 + 2 = 6
C. (-2,-6) means x= -2 and y = -6
so 3x - 2y becomes 3(-2) - 2(-6) = -6 - -12 = -6 + 12 = 6
Verified that the line passes by the last two points but not the first one.
First, you want to multiply 2 times 7 which is 14 then do 14 to the 4th power which is 38,416, then add that by 14 to the third power which is 2,744, so then you will get 41,160 which is your answer.
