Ok so we know that using 1/3 of the tank, Tanya managed to drive 3 1/2 hours.

That means if she used the entire tank, w
she would have been able to drive 3 times as long, or (3 1/2 x 3) hours, which is 10 1/2 hours.

This means if she used half the tank (1/2), she would have driven half of 10 1/2 hours, which is 5 1/4 hours

Hope this helped

Find all the solutions of sin x + cos x = 1 in the interval [0, 2pie).
Mashcka [7]

Answer:

X = 0,  π/2 in the interval  [0, 2pi).

Step-by-step explanation:

Use the auxiliary angle method:

R sin(x + a)  = Rsin x cos a + Rcos x sin a = 1

                        sin x         +    cos x             = 1

Comparing coefficients:

R cos a = 1 and R sin a =  1, so

tan a = R sin a / R cos a  = 1

So a = π/4 radians.

Also  R^2(sin^2 a + cos^2 a) =  1^2 + 1^2 = 2

Therefore R = √2.

So √2 sin (x +π/4 = 1

sin x + π/4 = 1/√2

x  + π/4 = π/4

x = 0 radians

Also

x = 0 +  π/2 = π/2.

Write a system of equations with the solution (-3,-8) in standard form.
Katyanochek1 [597]

Answer:

y=2x-2

y=3x+1

Step-by-step explanation:

To solve this I will be using the point slope formula

It is as follows

y-y₁=m(x-x₁)

We can choose any m value so I will be choosing m=2

(x₁,y₁) will be (-3,-8) respectively because all we want is for the line to pass through that point

so we have

y-(-8)=2(x-(-3)

We can simplify this to

y+8=2(x+3)

y+8=2x+6

y=2x-2

We then repeat this process but choose a new m (the m value doesn't really matter as long as it's not 0)

I will choose 3

so we have

y-(-8)=3(x-(-3))

Which gives u

y+8=3(x+3)

y+8=3x+9

y=3x+1

The answer would be .67 or .66666... since it’s infinite; or 2/3 in fraction form
