Answer:

Equation of line is \mathbf{y=-3x+3}

Option A is correct.

Step-by-step explanation:

We need to write an equation that represents the line that passes through the point (-1, 6) and has a slope of -3.

The equation will be of slope-intercept form: y=mx+b

where m is slope and b is y-intercept

We are given slope m =-3, we need to find y-intercept b

Finding y-intercept

using slope m=-3 and point (-1, 6)

y=mx+b\\6=-3(-1)+b\\6=3+b\\b=6-3\\b=3

So, y-intercept b is 3

Now the equation of line having slope m= -3 and y-intercept b = 3 is

y=mx+b\\y=-3x+3

Equation of line is \mathbf{y=-3x+3}

Option A is correct.

He roots of x2 − (<br> ) + 34 are 5 ± 3i.
GrogVix [38]
Use the quadratic formula, x=\frac{-b+ \sqrt{ b^{2}-4ac} }{2a}
(don't know how to type the "-"sign in the formula, so there is only the "+" in the formula)
in this case, a=1, c=34, b is unknown
from the roots, we can tell that -b+\sqrt{b^{2}-4ac } =2(5+3i)=10+6i

Note: the original equation already give b as -b, so -(-b)=10, b=10
using b^2-4ac=(6I)^2,
b^2-4*34=-36
b^2=100
you will also get b=10

Find mZLKM.<br> м.<br> M<br> K/(3x – 70)<br> 60°<br> L<br> mZLKM=<br> l
Bingel [31]

Answer:

125

Step-by-step explanation:

( 3x - 70 ) is exterior angle.

60 and x are interior angles.

Formula : -

Exterior angle of a triangle

= Sum of two interior angles in a triangle

3x - 70 = x + 60

3x - x = 60 + 70

2x = 130

x = 130 / 2

x = 65

m∠LKM = 3x - 70

= 3 ( 65 ) - 70

= 195 - 70

m∠LKM = 125
