The slope m =(5-1)/(4--1) = 4/5
The point slope equation is:
y - y1 = m(x-x1)
y-1 = (4/5)(x+1)
y = .8x + 1.8
Distance is SQRT(4^2 + 5^2) = SQRT (41)

Solve the equation x^2+17x+12=-3x^2 to the nearest tenth.
mote1985 [20]

Answer:

x=-\frac{17}{8}+\frac{\sqrt{97} }{8} or x=-\frac{17}{8}-\frac{\sqrt{97} }{8}

Step-by-step explanation:

x^2+17x+12=-3x^2

Add 3x^2 on both sides.

x^2+17x+12+3x^2=-3x^2+3x^2

x^2+17x+12+3x^2=0

Combine like terms;

4x^2+17x+12=0

Use the quadratic formula;

a=4

b=17

c=12

x=\frac{-b\frac{+}{}\sqrt{b^2-4ac}  }{2a}

x=\frac{-(17)\frac{+}{}\sqrt{(17)^2-4(4)(12)}  }{2(4)}

x=\frac{-17\frac{+}{}\sqrt{289-192}  }{8}

x=\frac{-17\frac{+}{}\sqrt{97}  }{8}

x=-\frac{17}{8}+\frac{\sqrt{97} }{8} or x=-\frac{17}{8}-\frac{\sqrt{97} }{8}
