Step-by-step explanation:

3x+9+4x-3+8x-6=180

15x=180

x=12

angle 1= 3x+9=36+9=45°

angle 2=4x-3=48-3=45°

angle 3=8x-6=96-6=90°

1) it's right triangle

2) it's isosceles triangle

Which equation represents a linear function?
Anna007 [38]

Answer:

y-2=-5(x - 2)

Step-by-step explanation:

Given:

The equations given are:

y-2=-5(x - 2)\\X+ 7 = -4(X + 8)\\y - 3 = y(x + 4)\\y + 9 = x(x - 1)

Now, a linear function is of the form:

y=mx+b

Where, 'm' and 'b' are real numbers and m\ne0

Equation 1: y-2=-5(x - 2)

Simplifying using distributive property, we get:

y-2=-5x+10\\y=-5x+10+2\\y=-5x+12

The above equation is of the form y=mx+b. So, it represents a linear function.

Equation 2: X+ 7 = -4(X + 8)

Here, both sides of the equation has same variable 'X'. So, it will form an equation of 1 variable. So, it's not a linear function.

Equation 3: y - 3 = y(x + 4)

Simplifying the above equation. This gives,

y-3=yx+4y\\y-4y-yx=3\\y(1-4-x)=3\\y(-3-x)=3\\y=\frac{3}{(-3-x)}

This is not of the form of the linear function. So, it is also not a linear function.

Equation 4: y + 9 = x(x - 1)

Simplifying the above equation. This gives,

y+9=x^2-x\\y=x^2-x-9

This is not of the form of the linear function. So, it is also not a linear function.
