Answer:
Step-by-step explanation:
y=mx+b
8=-7m+b
2=0m+b
subtract
6=-7m
-6/7=m
2=0m+b
2=b
y=-6/7x+2
change to standard from
y+6/7x=2
Step-by-step explanation:
The root of an equation is when x=0.
We need to rewrite this as 3x²-4x+10=0.
The quadratic formula is
(-b+or-sqrt(b²-4ac))/2a
so 4+or-sqrt(16-120)/2a
since the sqrt can no be negative this answer will have imaginary numbers.
(4+2i sqrt(26))6 and (4-2i sqrt(26))6
simplified is
x=(2+i sqrt(26))/3 and x=(2-i sqrt(26))/3
Answer:
Race completed in 48 minutes.
Step-by-step explanation:
Let the speed of Max on hoverboard is = x
Then as per question speed of Victoria on hoverboard = 3x
Now it has been given in the question that speed of Victoria on foot is 1/3 of the speed of Max on hoverboard that will be = x/3
Now we will form the equation.
As we know the formula speed = distance/time
Let the time taken by both to complete the race be t minutes.
Distance covered by Victoria in 12 minutes + Distance covered by Victoria on foot = distance covered by Max on hoverboard
Then the equation will be
12(3x)+(1/3)x(t-12)=xt






So 48 minutes it took to complete the race.
Y= 5x-45
On your graph go by 5's
On the y go down 9 which going by 5 makes it -45
Then go up 5 and one to the right and plot points keep going. 25/5=5
Your answer should be 31
Tell me if it was correct?
Thanks!
