y=3x-7

Step-by-step explanation:

lines are parallel hence gradient from the equation in question is the same as the gradient of the equation to be found.. comparing to y=mx+c, eq in question has grad 3... from the formula y-y1=m(x-x1) where (x1,y1) is equal to the point in question

What is the vertex of the function f(x) = x2 + 3x + ?
guapka [62]

The vertex of the function is at x = -3/2. We cannot find the y value with an incomplete equation.


To find the x value of a vertex, we use the equation -b/2a, in which a is equal to the coefficient of x^2 (in this case 1) and b is equal to the coefficient of x (in this case 3).


-b/2a

-3/2(1)

-3/2


This gives us that value. To find the y value, you would plug this into the equation. Since this equation is not complete, you cannot do that yet.

A clock has a diameter of 16 inches. how far does the hour hand travel during 5 hours? use 3.14 for pi.
valentina_108 [34]

Distance hour hand travel in 5 hours is 20.94 inches.

<h3>What is a diameter?</h3>
  • A diameter of a circle is any straight line segment that passes through the center of the circle and has endpoints on the circle in geometry.
  • It is also known as the circle's longest chord.
  • Both definitions apply to the diameter of a sphere.

To find the distance hour hand travel in 5 hours:

  • Let's say the hour hand completed one full round around the clock.
  • If this was the case, it would have been 2\pi×8 inches around.
  • We know that the hour hand only traveled 5 hours around the clock rather than 12, thus our formula is 2\pi×8×( 5/12 ).
  • Distance hour hand travel is 20.94 inches.

Therefore, the distance hour hand travel in 5 hours is 20.94 inches.
