Answer:
5 feet 9 in.
Step-by-step explanation:
15 feet = 180 in.
9 feet = 108 in.
108 in. + 3 in. = 111
180 in. - 111 in. = 69 in.
69 in. = 5 feet 9 in.
18 is probably D. for 19 both C and D are right so I'm not really sure which one you should write though...for 20 it's definitely 130 which is B
Solution:
To classify the system of equations as no solutions, the lines must be parallel (Not intersect).
<u>First, let's identify the equation forming the line.</u>
- Slope = Rise/Run = 2/-3 = -0.66
- Y-intercept = 0
- Equation formed: y = -2/3
We also know that the slope of the equation must be -1.5.
<u>A) 2x + 3y = 0</u>
- 3y = 0 - 2x
- => 3y = -2x
- => (y = -2x/3) ∦ (y = -2x/3)
<u>B) 2x + 3y = 6</u>
- => 3y = -2x + 6
- => (y = -2x/3 + 2) ║ (y = -2x/3)
<u>C) 2x - 3y = 9</u>
- => -3y = -2x + 9
- => y = -2x/-3 + 9/-3
- => (y = 2x/3 - 3) ∦ (y = -2x/3)
<u>D) y = 3x + 2</u>
- (y = 3x + 2) ∦ (y = -2x/3)
Option B is correct.
Step-by-step explanation:
L.H.S=(1-cosB)(1+cosB)
=(1-cos^2B). {using (a+b) (a-b)=(a^2-b^2)in second step}
=sin^2B
=1/cosec^2B
Therefore,L.H.S=R.H.S proved
first u do the the thing in the parenthesis and then u multiply it by 67 and then add 9
