Answer:
y = x + 3
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 )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (1, 4) and (x₂, y₂ ) = (4, 7)
m = 
= 
= 1, hence
y = x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation.
Using (1, 4), then
4 = 1 + c ⇒ c = 4 - 1 = 3
y = x + 3 ← equation in slope- intercept form
I don't know what a radicals is and I can't really show my work cuz I just do it all in my head but I'll solve it for you.
A) (2)(x^2-5x-4) this one can't be simplified anymore unless you use the quadratic formula which I'm too lazy to do
B) (2x-1)(2x-5)
X=1/2 or 5/2
4i = b
6(i-6) = b-6
6(i-6) = 4i - 6
6i - 36 = 4i - 6
2i - 36 = -6
2i = 30
i = 15 years old
b = 60 years old
Check:
15 * 4 = 60
9 * 6 = 54 :)
Answer:
55 because if u take the 6 and 3 and multiply then subtract 4 and whatever you get that's your answer same with the others
