4/21 cannot be simplified any more due to the fact that while 4/21 can be divided by other numbers, both numbers have to be divided by both the same number. Since there is no number that can go into both 4 and 21, 4/21 is the simplest it can get

May I please get a step by Step for this

natulia [17]

Answer:

Step-by-step explanation:

h=16t^2+98=?

subtract 98 from both sides to get

h-98=16t^2

(the 98 on the right cancels)

now divide by 16 on both sides

h-98/16=t^2

(the 16 on the right cancels)

lastly take the square root on both sides

square root(h-98/16)= t

if you know what h is fill it in and it will give you your answer

What is the slope of the line through (- 1, - 7) and (3, 9) ?

Fynjy0 [20]

Answer:

C. 4

Step-by-step explanation:

Use the slope formula:

$m=\frac{y2}{x2} -\frac{y1}{x1}$

m = the slope.

Substitute the values into the formula:

$\frac{9}{3} -\frac{-7}{-1} =\frac{?}{?}$

Solve:

$\frac{9}{3} -\frac{-7}{-1} =\frac{16}{4}$

Simplify 16/4:

$\frac{16/4}{4/4} =\frac{4}{1}=4$
