Solve for y then find the slope and y intercept and graph <br> y=4x+3<br><br> y=<br> b=<br> m=
Ugo [173]

Answer:

y = 4x+3

m =4

b =3

Step-by-step explanation:

y=4x+3

This is already solved for y

This is in slope intercept form

y = mx+b where m is the slope and b is the y intercept

y = 4x+3

m =4

b =3

X² - 8x - 33=0<br> complete the square
Andreas93 [3]
<h2>Answer:</h2><h2></h2><h2>\boxed{x_{1}=-3} \\ \\ \boxed{x_{2}=11}</h2>

<h2>Explanation:</h2>

Step 1. Write x^2 - 8x - 33=0 in the form x^2+2ax+a^2=0

2a=-8\quad :\quad a=-4

Step 2. Add and subtract (-4)^2 to the left side of the equation

x^2-8x-33+\left(-4\right)^2-\left(-4\right)^2=0 \\ \\ \\ But: \\ \\  x^2+2ax+a^2=\left(x+a\right)^2 \\ \\ x^2-8x+\left(-4\right)^2=\left(x-4\right)^2

Step 3. Complete square

\left(x-4\right)^2-33-\left(-4\right)^2=0 \\ \\ \left(x-4\right)^2-49=0 \\ \\ (x-4)=\pm \sqrt{49} \\ \\ x-4=\pm 7 \\ \\ \boxed{x_{1}=-3} \\ \\ \boxed{x_{2}=11}
