well the equation need to be set up as y=mx+b, m being the slope and b being the y-intercept.
so m=1; b=3
your equation is y=1x+3
Answer:
y = ( x-4)(x+7)
Step-by-step explanation:
When we know the zeros of the equation, we can write the equation in the form
y= a(x-z1) (x-z2) where a is a constant and z1 and z2 are the zeros (solutions)
y = a( x-4)(x--7)
y =a( x-4)(x+7)
Since its says write an equation, we can pick a and I will let a=1
y = ( x-4)(x+7)
You can use F.O.I.L. for this, which if you don't know stands for first outer inner last, so multiply the first in each parentheses, then the outer, then the inner, then the last. yours would be 3*5+3*√7+(-√7)*5+(-√7)*√7 => 15+3√7-5√7-7 => 8-2√7
Final answer:
8-2√7

Hi there!
To find x, we'll need to proceed methodically. First, we'll start by finding the length of ST. The 30-60-90 relationship tells us that ST = 2. Then, we can find RT, also using the 30-60-90 relationship. RT = 4. Lastly, we can use the 45-45-90 relationship to determine that x = 4.
Hope this helps!! :)
