Answer:
x = -5 + 
Step-by-step explanation:
f(x) = x² + 10x - 1
x² + 10x = 1
x² + 10x + 25 = 1 + 25
(x + 5)² = 26
take the square root of each side to get:
x + 5 = √26
x = √26 - 5 or -5 + √26
Solve for x by simplifying both sides of the equation, then isolating the variable.
x = -4
Hope this helps! :)
Happy New Years!
5/3 = 315/x
5*x = 5x
3*315 = 945
5x = 945
5x/5 = 945/5
x= 945/5
x=189
Final answer: The riders are 189
Answer:
15/10
Step-by-step explanation:
Since it is adding you need to get a common denominator(bottom number).
I know that 2 × 5 = 10 so now we multiply 3/5 × 2
we get 6/10
now the problem is 9/10 + 6/10
9 + 6 = 15 and the denominator is 10
15/10
