Answer: 4.5 3.2 6.7
Step-by-step explanation:
Answer:
The other point of intersection is (1.5,4.5)
Step-by-step explanation:
<u><em>The correct quadratic equation is</em></u>
step 1
Find he y-intercept of the parabola
The y-intercept is the value of y when the value of x is equal to zero
so
For x=0
therefore
The y-intercept is the point (0,3)
step 2
Find the equation of the line
The equation in slope intercept form is
we have
substitute
step 3
Find the other point of intersection
we have
Equate both equations
solve for x
we know that one solution is x=0
simplify x
Find the value of y
substitute the value of x in any equation (line or parabola)
therefore
The other point of intersection is (1.5,4.5)
On substituting x= 9 in the above equation,
y= 9-5= 4
and, the y coordinate is also same i.e. 4
Yes.
It satisfies the equation.
I hope this helps you...
Well... you need to find your slope first for starters. In order to find you slope it would be y2-y1/x2-x1... rise/run. So that would make your slope 6/3 and you can simplify that to 2/1 because divide it by 3. In order to find your y-intercept, you need to have (x) at 0 and wherever (y) is on that line, it would be your y-intercept.
Answer:
4.5 hours
Step-by-step explanation:
If 2 miles takes 1.5 hours, then 6 miles will be 4.5 hours.
2 miles = 1.5 hours
6 times 1.5 = 4.5
Therefore, 6 miles will take 4.5 hours.
