Its a multiplication by -3 on each term, so I think you're gonna answer is by r=-3, maybe?
Answer:
2
Step-by-step explanation:
f(x)=2x^2+9x-5
When we are find how many times it intersects the x axis, we are finding the zero's. Set the equation equal to zero
0=2x^2+9x-5
Factor the equation
0 = (2x+1) (x-5)
2*1
1*-5 = -5
2*-5 +1*1 = -9
This checks for the first last and middle terms so we factored correctly
Then using the zero product property
2x+1 = 0 and x-5 =0
2x = -1 x=5
x = -1/2 and x=5
This function crosses the x axis 2 times
Answer:
he travels 249 miles on saturday
Step-by-step explanation:
<u> 62.25 </u> <u> x</u>
1 = 4
you must multiple the distance travled in one hour by the number of hours of driving. In this case 4. This is if he did not change speeds ;)
4 x 62.25 = 249 miles
Hope this helps :) Please mark brainliest if you see fit :)
Yes, because 1/4 plus 1/4 equals 2/4 (or 1/2) and 3/4-2/4 equals 1/4.
