Answer:

12.25 miles

Step-by-step explanation:

We can write a proportion to solve. Miles over time in minutes

1 hour = 60 minutes

1 hours 10 minutes = 60+10 = 70 minutes

3.5 miles x miles

--------------- = --------------

20 minutes 70 minutes

Using cross products

3.5 *70 = 20x

245 = 20x

Divide each side by 20

245/20 = 20x/20

12.25 =x

Jimmy can go 12.25 miles

Does the point (2,3) lie on the line y=3/4x-2

dezoksy [38]

No.

If you substitute x with 2 and y with 3, it doesn't equal meaning its not a point.

H=3.4s- start with the problem
20=3.4s- substitute the known number(s)
20/3.4=3.4/3.4 s- divide both sides by 3.4
The answer is about 5.88, your answer should be between 5 and 6

Solve the simultaneous equations<br> y = 4x + 1<br> y = 2x^2+ 7x - 1

mixer [17]

Answer:

$Given,\\y = 4x+1......(1)\\y = 2x^2+7x-1.............(2)\\Equating~equation (1)~and~(2),\\4x+1 = 2x^{2} +7x-1\\or, 2x^{2}+7x-4x-1-1=0\\or, 2x^{2} + 3x-2=0\\or, 2x^{2} +4x-x-2=0\\or, 2x(x+2)-1(x+2)=0\\or, (x+2)(2x-1)=0\\i.e. x=-2 ~or~ \frac{1}{2} \\When~x=2,~equation(1)~becomes ~y=4(-2) +1=-7\\When~x=-\frac{1}{2},~equation (1)~becomes~y=4(\frac{1}{2}) +1 = 2+1=3$

So, the required values of x are -2 and 1/2 and that of y are -7 and 3.
