In the third quadrant, the tangent is positive.
tan(θ) = tan(arcsin(0.7660)) ≈ 1.1916
This one isn't too hard, just plug in each value!
x = -1
y = -4(-1) + 3
y = 7
x = 0
y = -4(0) + 3
y = 3
x = 1
y = -4(1) + 3
y = -1
x = 2
y = -4(2) + 3
y = -5
Let this number be x.
"Six less than seven times a number is equal to -20" can be represented by the equation 7x - 6 = -20. We need to solve for x.
First, add 6 from each side so we can have the variables on a side and the numbers on the other:
7x - 6 + 6 = -20 + 6
7x = -14
Then, you divide each side by 7 so we can get the variable x alone on a side, and its value on the other side:
(7x)/7 = -14/7
x = -2
You can re-check your answer (very important):
7x - 6 = 7 (-2) - 6 = -14-6 = -20
The answer has been approved.
Hope this Helps! :)
The product means multiply
the product of a number and 5......lets say ur number is x
5x
is means =
2 less then the number...
x - 2
so we have : 5x = x - 2 <== ur equation
Yo sup??
we can solve this question by applying trigonometric ratios
sin31=TU/TV
TV=TU/sin31
TV=7.76
=7.8
Hope this helps.
