One of the angles in an intersecting line mesures 30

1 answer:

7 0

Think of the point, P, where the lines intersect as the center of a circle. The four angles with vertex P add up to 360 degrees. The given angle and its paired vertical angle are both 30 degrees. So, the other two angles are also vertical angles with sum 300 degrees (so each of them is a 150 degree angle).

Answer:

y = -2x + 5 [ 1st option ]

Step-by-step explanation:

Consider any two points , say

(1,3)
(2,1)

Firstly let's find the slope of the line as ,

=> m = y₁ - y₂ / x₁ - x₂

=> m = 3-1 / 1-2

=> m = 2/-1

=> m = -2

Third point is, (3 , -1) . Using slope point form .

=> y - y₁ = m ( x - x₁ )

=> y - (-1) = -2( x - 3)

=> y + 1 = -2x +6

=> y +2x +1-6=0

=> y +2x -5 = 0

=> y = -2x + 5

On looking at options first one is correct

<h3>Hence the equation of line is y = -2x + 5.</h3>

Solve the inequality -4y+6<-4

svet-max [94.6K]

Answer:

y = 5/2

Step-by-step explanation:

-4y+6<-4 subtract 6 from both sides

-4y + 6 - 6 < -4 - 6 = -4y < -10 since both sides are negative we multiply it by -1 and get ➡ 4y < 10

Now divide both sides by 4

4y ÷ 4 < 10 ÷ 4 ➡ y < 5/2
