Answer:
y = 6x + 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 6 and given point (0, 4 ) ⇒ c = 4
y = 6x + 4 ← equation of line
The answer is letter c because it doesnt have a closed circle so it doesnt need a line under the >

Step-by-step explanation:
<u><em>The complete question is</em></u>
Jaden and Joel both worked at the coffee shop today. Jaden's total cups of coffee made is represented by f(x), and Joel's total cups of coffee made is represented by g(x). Use the functions below to write a function that represents the total cups of coffee they made today.
f(x) = 4x − 1
g(x) = 2x + 3
Options
6x + 2
2x + 1
2x − 4
4x + 4
we know that
To find out the total cups of coffee they made today, sum Jaden's total cups of coffee plus Joe's total cups of coffee
so
f(x)+g(x)
substitute the values
![(4x-1)+( 2x + 3)](https://tex.z-dn.net/?f=%284x-1%29%2B%28%202x%20%2B%203%29)

Step-by-step explanation:
It seems here that they are asking us to solve for x
to do this we first need to factor
Since we can't factor this using the normal method we can instead do this
x^2 -4x-17=0
add 4 to both sides as it is a perfect square
x^2 - 4x + 4 = 17 +4
(x-2)^2 = sqrt 21
x-2 = ± 4.58
x -2 = 4.58 x-2 = -4.58
x= 6.58 x=-2.58
Or just say x=2+√21 or x=2−√21
