Write the equation in slope-intercept form of the line given that the slope of the line is 5 and the line passes
oee [108]

Answer:

let's go...

Step-by-step explanation:

We should use this function to find the standard form the line :

y - y(given \: point) = (gradient) \times ( \: x - x(g \: p) \: ) \\ y - 4 = 5 \times (x - 3) \\ y - 4 = 5x - 15

subtract the sides of the equation plus 4

y = 5x - 15 + 4 \\ y = 5x - 11

And we're done buddy.

good luck ♥️♥️♥️♥️♥️.

Find the equation of the line through (2, 3, 0) perpendicular to the vectors a = (1, 2, 3) and b = (3, 4, 5).
densk [106]
The cross product a×b is a vector perpendicular to both. That cross product is
  (1, 2, 3)×(3, 4, 5) = (-2, 4, -2)

This can have common factors removed and be sign-adjusted to (1, -2, 1), so the equation of the line can be written in parametric form as ...
  (x, y, z) = (2, 3, 0) + t·(1, -2, 1)

_____
When working with vectors and matrices, a suitable calculator can be very helpful. There are several phone and tablet apps and web sites that can do these calculations for you.

Sharon kicks a ball from the ground into the air with an upward velocity of 64 feet per second. The function h = -16t2 + 64t mod
iren2701 [21]
When the ball reaches the ground is equal to one of the zeros, or x-intercepts. In order to find the zeros of a function, you need to factor the equation.
y=16x^2+64x
y=-16x(x-4)
The zeros are x=0 and x=4
Therefore the answer is D, after 4 seconds.
Hope this helps!
