Look at the graphs of y = 4x2 + 7x − 11 and y = 3x + 4. At which points are the two equations equal?

1 answer:

6 0

This is basically asking for the point where both equations intersect. If you have a graphing calculator, you can graph, then hit 2nd, CALC, Intersect, then hit enter twice when it asks for first and second curve, and then the x value is the answer. This is for a TI-84 Plus, so if you want me to explain how to do this by hand, then just let me know.

Answer:

Hello!!!

In this specific case the constant of proportionality is s (speed).

Step-by-step explanation:

The constant of proportionality stay "constant" (as the name suggests) in a certain case.

meaning, the speed itself remains constant at any given distance or time.

You can use the constant of proportionality and either distance or time to find the missing varliable since it remains constant.

you can also switch up the formula:

d=st

t=d/s

s=d/t

i really hope this helps!!!!!

Answer:

$196 m^{2}$

Step-by-step explanation:

A square is a shape that which all sides are equal

14 is one side of the square and to find the area of a square/rectangle, you do length*width

14*14=196

Answer:

-3<x<3

Step-by-step explanation:

let y=0

0=x^2-9

0=(x+3)(x-3)

x=-3 and x=+3
