Answer:

you find the x and y intersepts and draw the line

Step-by-step explanation:

if we break down the equasion in the end it's y=x+4 and from there we can find the intersepts by canceling out, y=x+4 becomes y=4 and 0=x+4 wich is x=-4

Find a polynomial with a degree of 3, and the zeros 1,7, & -4 with no other zeros.
jarptica [38.1K]

Answer:

f(x)=(x+4)(x-7)(x-1)

Step-by-step explanation:

zeroes are when you plug in that x value and get y=0

therefore if you set x = that number and solve for 0 you get a "function"

multiplying these together will yield the complete 3rd degree polynomial

x = 1

x-1=0

x=7

x-7=0

x=-4

x+4=0

f(x)=(x+4)(x-7)(x-1)

If needed you could expand but I'm too lazy

Make x the subject of the formula<br> х<br> +b=<br> a
blagie [28]

Answer:

x = a(c - b)

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Equality Properties

Step-by-step explanation:

<u>Step 1: Define Equation</u>

x/a + b = c

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Subtract <em>b</em> on both sides:                    x/a = c - b
  2. Multiply <em>a</em> on both sides:                     x = a(c - b)
