Answer:
Option D is the correct answer.
Step-by-step explanation:
The equations are:
5x - 3y = -11 Eqn 1
2x - 6y = -14 Eqn 2
We have to find the value of y so we will eliminate x.
Multiplying Eqn 1 by 2
2(5x-3y=-11)
10x-6y=-22 Eqn 3
Multiplying Eqn 2 by 5
5(2x-6y=-14)
10x-30y=-70 Eqn 4
Subtracting Eqn 4 from Eqn 3
(10x-6y)-(10x-30y)= -22-(-70)
10x-6y-10x+30y = -22 + 70
24y = 48
Therefore,
Option D is the correct answer.
Intersecting on the y axis means x=0.
Plug x=0 in the equation to find out the y value of the intercept> 0+4y-24=0, y=6
so the both line passes the point (0,6)
two perpendicular lines have slopes that are negative reciprocals of each other, that is, if one slope is a/b, the other is -b/a
In this case, the line x+4y-24=0, 4y=-x+24, y=-1/4 x + 6, the slope is -1/4, so the slope of the perpendicular line is 4/1.
the equation is y=4x+6
Answer:
23.6°
Step-by-step explanation:
In this question we have to use some trigonometry to work out angle XVW. Since we are working out angles all of the trigonometric functions will have to be to the ⁻¹. The first thing we need to identify is will formula will we use out of the following:
Sin⁻¹ = Opposite ÷ Hypotenuse
Tan⁻¹ = Opposite ÷ Adjacent
Cos⁻¹ = Adjacent ÷ Hypotenuse
-------------------------------------------------------------------------------------------------------
10 = Hypotenuse
4 = Opposite
-------------------------------------------------------------------------------------------------------
We know which formula to use because the length won't be in the triangle for example we will be using the Sin triangle because we don't have an adjacent. If we don't have an adjacent then the other formula's won't work.
Now we substitute in the values to find the value of angle XVW
Sin⁻¹ = Opposite ÷ Hypotenuse
Sin⁻¹ = 4 ÷ 10
The value of angle XVW is 23.57817848
