The answer is 9/23 you simply both sides of the equation, subtract 7x from both sides, divide both sides by -23

The idea is to get th numbers on one side of the equal sign and the x’s on the other side.

In order to bring anything across the equal sign you use the inverse operation.

Start by adding 2 to both sides giving you:

8x = -7 + 7x

Next subtract 7x from both sides:

x = -7

A Walmart truck driver estimates that it will take him 12 hours to drive 1152 km. After 5 hours, he has driven 520 km.
san4es73 [151]

(a) He would drive 96 km in an hour because 1152 divided by 12 is 96

(b) He is technically on schedule because he is driving 104 km per hour, instead of 96, so if he keeps driving at the same rate, he should get there in under 12 hours

Consider an arbitrary ellipse x 2 a 2 + y 2 b 2 = 1. (Assume a, b > 0.) (a) Find a parametrization of the ellipse using the d
uysha [10]

Answer:

α(t) = (-a*Sin(t), b*Cos (t))    where t ∈ [0, 2π]

Step-by-step explanation:

Given an arbitrary ellipse (x²/a²) + (y²/b²) = 1       (a, b > 0)

The parametrization can be as follows

x = -a*Sin(t)

y = b*Cos (t)

then

α(t) = (-a*Sin(t), b*Cos (t))    where t ∈ [0, 2π]

If  t = 0

α(0) = (-a*Sin(0), b*Cos (0)) = (0, b)

If  t = π/2

α(π/2) = (-a*Sin(π/2), b*Cos (π/2)) = (-a, 0)

If  t = π

α(π) = (-a*Sin(π), b*Cos (π)) = (0, -b)

If  t = 3π/2

α(3π/2) = (-a*Sin(3π/2), b*Cos (3π/2)) = (a, 0)

If  t = 2π

α(2π) = (-a*Sin(2π), b*Cos (2π)) = (0, b)

We can see the sketch in the pic.
