Csc α - sin α =cos α cot α<br> Show how this is an identity?
Savatey [412]
Csc a - sin a = cos a cot a
1/sin a - sin a = cos a (cos a / sin a)
(1 - sin^2 a)/sin a = cos^2 a/sin a
cos^2 a/sin a = cos^2 a/sin a

Therefore, the given equation is an identity.

Gilda drove 650miles at an average speed of 50 miles per hour.how many miles per hour faster would she have had to drive in orde
zzz [600]
T=650mi(hr/50mi)=13 hr

t-1=12 hr

12=650/(50+v)  multiply both sides by 50+v

600+12v=650  subtract 600 from both sides

12v=50  divide both sides by 12

v=25/6 mph

v≈4.17mph

Nataliya [291]
We have that
<span>3x-2y=8 -----> equation 1
2x+3y=Q----> equation 2

the solution is the point </span><span>(4,2)
in the equation 2 substitute the value of
x=4
y=2
so
</span>2x+3y=Q------> 2*4+3*2=Q-------> Q=8+6------> Q=14
<span>
the answer is
Q=14

Solve for 3/4u = 12<br> .<br> Simplify your answer as much as possible.
Wittaler [7]

Answer:

u = 16

Step-by-step explanation:

Given

\frac{3}{4} u = 12

Multiply both sides by 4 to eliminate the fraction

3u = 48 ( divide both sides by 3 )

u = 16

Determine which ordered pair makes the equation true.<br> 2x + y = 11
slavikrds [6]
There is no one ordered pair that makes the equation true, this is a line which has infinitely many ordered pairs that are true...

2x+y=11  subtract 2x from both sides and you have the line in slope intercept form..

y=11-2x

For any real given value of x, you will get one real unique corresponding value for y, resulting in infinitely many unique (x,y) values, points, or ordered pairs, satisfying the given equation.

I assume that you were given "choices" to pick from because of the above reality.  So if any of your choices does not satisfy y=11-2x it is not an ordered pair satisfying the equation.
