Plug in the 2 values for x and y into the equation and see if it works out.
6(-9)-(3)/2=14 => -54-3/2=14 => -55 -1/2 = 14
Which false so the first point is not a solution.
Next point:
6(2)-(-4)/2=14 => 12+2=14 => 14=14
This is clearly true, so the second point is a solution.
Final answer:
Answer choice B, the first is not a solution but the second is.
Hope I helped :)
d/dx cot(x) = -csc²(x)
d/dx sin(x) = cos(x)
So, if f(x) = 4 cot(x) + 10 sin(x), then
f '(x) = -4 csc²(x) + 10 cos(x)
yes, if you would to put (-5,2) back into those two equations it would to be true
(-5 being your x)
(2 being your y)
(2)=-2(-5)-8=2, so
2= 10-8=2
2=2=2
You must factor.
The factored form is equal to the assigned form.
Values a, b correspond to the factored 1, -1.
Value of x however remains unknown. But we can change that.
Given factored result,
We can set expression equal to 0 then find such x that when added with number a or b results with 0.
Hence x has 2 solutions.
Hope this helps.
Answer:
B. 22 cm
Step-by-step explanation:
Perimeter of a parallelogram is 2(l+w)
= 2(8+3)
=2(11)
=22cm
