Answer:
Step-by-step explanation:
The area 
of a triangle is equal to half the product of its length (L) because of its height (h).
The base of the triangles is 
The height of the triangles is 
Then the area of one of the triangles is:
The figure is formed by 12 equal triangles, then the area of the figure 
is:
<span>6-2x=6x-10x+4
6-2x=-4x+4
Add 4x to both sides: 6+2x=4
Subtract 6 from both sides" 2x = -2
divide 2 from both sides: x=-1</span>
Answer:
x=2,y=5
Step-by-step explanation:
y=8x-11 ----(1)
y=-7x+19----(2)
Replace (1) in (2)
8x-11 =-7x+19
8x+7x=19+11
15x =30
x =30÷2
x =2
If x=2,then replace x=2 in (1)
y=8(2)-11
y=16-11
y=5

Solution:</h3>
A linear function is a straight line formed on a coordinate plane.
<u>To classify an equation as a linear function:</u>
- It must not have any exponent in the equation.
- If there is a fraction, the denominator of that fraction must not multiply by x.
If any of these two occurs in an equation, the line can form a curve in a line, which is a non-linear function. A non-linear function is a curved line formed on a coordinate plane.
<u>Option A - y = x³ + 1:</u>
- This equation has an exponent in the variable x. Hence, this is a non-linear function.
<u>Option B - 5x/6 = y - 4:</u>
- This equation has no exponents in the equation. Hence, this is a linear function and also our answer.
<u>Option C - y = 8x²</u>
- This equation has an exponent in the term 8x². Hence, this is a non-linear function.
<u>Option D - y = 1/5x</u>
- The denominator of the fraction on the RHS side is multiplied by x. Hence, this is not a linear function.
Hence, Option B is correct.
