Answer:
Domain: [-4, 4]
Range: [-3, 5]
Function? No
Step-by-step explanation:
Domain is all x-values that can be inputted in the graph that returns an output.
Range is all y-values that are outputted when x is inputted.
A function has to pass the Vertical Line Test.
The measure of angle U will be equal to the measure of angle W.
Because W is pronounced "double u", W = 2 * U.
Therefore U = W and U = 2 * W, so both U and W = 0.
Just kidding.
The correct answer is the smallest prime number greater than 40.
Step-by-step explanation:
distance / rate = time
x = original speed mph
60/x = t
Then at 5 mph faster
60/(5+x) = t - 6 re-arranged for t = 60/(5+x) + 6
equate the two definitions of 't' then solve for 'x'
60/x = 60/(5+x) + 6
60 = 60x/(5+x) + 6x
60(5+x) = 60x +6x(5+x)
300 + 60x = 60x + 30x + 6x^2
6x^2 +30x -300 = 0 Use Quadratic Formula to find x = 5 m/hr

For every
y miles Annabelle drove, Daniel drove miles.
Submit Answer
Answer:
I think it's 1.67 miles
Step-by-step explanation:
24:40
1 /24 = x/40
24x/24 = 40/24
1 = 1.67 miles
I hope this helps?
For every 1 mile Annabelle drove, Daniel drove 1.67 miles.
I may be wrong.
Probably am...

Answer:
(7x - 2)(3x^2 - 4)
See below.
Step-by-step explanation:
21x^3 - 9x^2 - 28x + 12
3x^2(7x - 3) - 4(7x - 3)
The common factor in this is 7x - 3. Use the distributive property to bring it out.
(7x - 3) [(3x^2 ) - 4]
(7x - 3)(3x^2 - 4)
You could factor 3x^2 - 4 but most times, since you can't reduce this to an integer result, you just leave it as it is.
If you have to use surds then the answer could be
(7x - 3)(√3 - 2)(√3 + 2)
Answer:
(7x-3) (3x^2-4)
