Use the given x and y values to write a direct variation
equation.
x = 2, y = 30
Answer:
y = 15x
Step-by-step explanation:
Given x and y are in direct variation then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition x = 2, y = 30, then
30 = 2k ( divide both sides by 2 )
15 = k
y = 15x ← equation of variation

the question: “which trig. ratio woild you use to find the missing side?”
Answer:
Step-by-step explanation:
It's not the tangent. The tangent relates two sides neither of which is the hypotenuse, which you are given.
The trig ratio you would use is the one that relates the angle to the side opposite the angle and the hypotenuse.
That is the definition for the Sine.
Share £160 in the ratio 1:9
Answer:
let ratio be x and9x
x +9 x=£160
x=£160/10
x=£16
9x=£16×9=£144
Answer:
16 and 144
Step-by-step explanation:
Breaking 160 into 1+9 = 10 parts
1 part would be 16
the rest would be 9 parts = 160 - 16 =144

Table to Linear Equation
Answer:
Y=-5X+1
Step-by-step explanation:
Answer:
y = -5x + 1
Step-by-step explanation:
y = mx + b
m = [tex]\frac{y_{2}- y_{1} }{x_{2}- x_{1}}[/tex] = [tex]\frac{-9-(-4)}{2-1} = -5[/tex]
y = -5x + b: then plug in a point to find b
-19 = -5(4) + b
-19 = -20 + b
b = 1
Plug in all the values to get: y = -5x + 1
Distribute 3x ( -x + 4).

Two parallel lines are cut by a transversal as shown below.
Suppose m<8=109. Find m<2 and m<3.
Answer:
measure 2 has to be 109 due to the alternate interior angles theorem. Measure 3 has to be 71 due to the supplementary angles theorem.
Angles 8 and 2 are alternate interior angles so they will be the same therefore,m∠2 and m∠3 will be 109° and 71° respectively.
What is an angle?An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.
The identical endpoint of the two rays—is known as the vertex.
Given two parallel lines a transversal.
Angles 8 and 2 are alternate interior angles.
m∠8 = m∠2
m∠2 = 108°
Now,m∠2 and m∠3 are supplementary angles.
Therefore,m∠3 = 180° - 108° = 71°
Hence "Angles 8 and 2 are alternate interior angles so they will be the same therefore,m∠2 and m∠3 will be 109° and 71° respectively".
