Answer: Y=-1/4x

Step-by-step explanation:

A good way to find an equation of a line is to look for the slope. An obvious spot on this line would be when it crosses (0,0), and another one to the right would be when it crosses at (4,-1).

The slope is rise over run, or if we use the two points we found, "rise" would be -1, because it's dropping 1 unit when going from (0,0) to (4,-1), and the "run" would be 4, because it moves to the right 4 from (0,0) to (4,-1).

Putting these two values together we get:

m (slope) = rise / run

m = -1 / 4

Out of all the equations we're given, we can look for the one with a slope of -1/4, which is given to us:

y = (-1/4)x

Answer: x² + 4x - 32

Step-by-step explanation: So to multiply these two binomials together, let's use the F.O.I.L. method.

Remember, F.O.I.L. stands for First, Outter, Inner, Last.

This is because we start with the product of the first terms which is x², then we add the product of the outer terms which is 8x, then we add the middle terms which is -4x, and then we add the product of the last terms which is -32.

So we have x² + 8x + -4x + -32.

Combining the like terms 8x + -4x, our final answer is x² + 4x - 32.

$\large\underline{\rm Solution }:-$

Given function to us is ,

$\implies f(x) = 3x^3 - 5x + 1$

The domain of the expression will be all <u>real </u><u>numbers</u> except where the given expression is not defined . Therefore , the domain is ,

$\underline\text{ In Interval Notation :- }$

$\implies \boxed{ Domain : ( -\infty , +\infty ) }$

$\underline\text{ In Set Builder Notation :- }$

$\implies \boxed{ Domain : \{ x | x \in \mathbb{R} \}}$

Please need help ASAP Many solutions exist for the system of equations graft below

Answer:

Zero

Step-by-step explanation:

The solutions to a system of equations are where the lines intersect. These lines have the same slope meaning they are parallel. Parallel lines never intersect, therefore there are zero solutions.
