Answer:
756000
Step-by-step explanation:
You will multiply 30x60(There are 60 seconds in a min)=1800
Then Multiple 420x1800=756000
Answer:
it would A)y =-3x
Step-by-step explanation:
Now, if we solve for "h", and thus put the equation in slope-intercept form,
notice what the slope is, and recall that the slope of an equation is just the "average rate of change".
Rewrite it in the form a^2 - b^2, where a = 5x and b = 8
(5x)^2 - 8^2
Use the Difference of Squares; a^2 - b^2 = (a + b)(a - b)
<u>= C. (5x - 8)(5x + 8)</u>
The answer is x=2
Remember, first add/substract the like terms, in this case 6x-10x to get -4x. Then, add 8x to negative 8x to cancel it out and do the same thing to -4x. Do this with all your terms and you should get 4x=8. Then divide both sides by 4 to get x=2.
