In the diagram below, BD AE, BF bisects ZABD, mC = 88° and

kotykmax [81]

Answer:

40

Step-by-step explanation:

$180 - 116 = 64$

$180 - 64 \times 2 = 52$

$180 - 52 - 88 = 40$

Which of these lines is perpendicular to the line y = 3x + 2?

Morgarella [4.7K]

Answer:

(c) $y=\frac{-1}{3}x+4$ will be perpendicular to the line y = 3x+2

Step-by-step explanation:

We have given the the equation of line as y = 3x+2

We know the equation of line as y = mx+c , here m is slope and c is intercept

On comparing with standard equation of line m = 3

We know that slope of perpendicular line is $=\frac{-1}{m}$

So the slope of the line which is perpendicular to y = 3x+2 will be $=\frac{-1}{3}$

Now (a) Line is given as $y=\frac{1}{3}x+3$ its slope is $\frac{1}{3}$ so it will be not perpendicular

(b) Line is given as $y=\frac{1}{3}x+2$ its slope is $\frac{1}{3}$ so it will be not perpendicular

(c) Line is given as $y=\frac{-1}{3}x+4$ its slope is $\frac{-1}{3}$ so it will be perpendicular to the line y = 3x+2

(d) Line is given as $y=3x+\frac{1}{2}$ its slope is 3 so it will not perpendicular to the line y = 3x+2

Lee is thinking of 2 numbers, the product is 18.the quotient is 2. what are yhe two numbers?

jeka94

$xy=18\\
\dfrac{x}{y}=2\\\\
xy=18\\
x=2y\\\\
2y\cdot y=18\\
2y^2=18\\
y^2=9\\
y=-3 \vee y=3\\\\
x=2\cdot (-3) \vee x=2\cdot 3\\
x=-6 \vee x=6\\\\
\boxed{(x,y)=\{(-6,-3),(6,3)\}}$

Which is an equation in point-slope form of the line that passes through the points (4,5) and (-3,-1)?

Annette [7]

(4,5),(-3,-1)
slope = (-1 - 5) / (-3 - 4) = -6/-7 = 6/7

y - y1 = m(x - x1)
slope(m) = 6/7
using points (-3,-1)...x1 = -3 and y1 = -1
now we sub...pay attention to ur signs
y - (-1) = 6/7(x - (-3) =
y + 1 = 6/7(x + 3) <===
