Answer:

Check the picture below.

$20x+5y=110\implies 20x=110-5y\implies x=\cfrac{110-5y}{20} \n\n\n x=\cfrac{110}{20}-\cfrac{5y}{20}\implies x=\cfrac{11}{2}-\cfrac{y}{4} \n\n[-0.35em] ~\dotfill\n\n (20x + 5y) + 40 + (2x + 5y) = 180\implies \stackrel{(20x + 5y)}{110} + 40 + (2x + 5y) = 180 \n\n\n 150+2x+5y=180\implies 150+2\stackrel{ x }{\left( \cfrac{11}{2}-\cfrac{y}{4} \right)}+5y=180 \n\n\n 150+11-\cfrac{y}{2}+5y=180\implies \stackrel{\textit{multiplying both sides by }\stackrel{LCD}{2}}{2\left( 150+11-\cfrac{y}{2}+5y \right)=2(180)}$

$300+22-y+10y=360\implies 322+9y=360\implies 9y=38 \implies \boxed{y=\cfrac{38}{9}} \n\n\n \stackrel{\textit{since we know that}}{x=\cfrac{11}{2}-\cfrac{y}{4}}\implies x=\cfrac{11}{2}-\cfrac{1}{4}y\implies x=\cfrac{11}{2}-\cfrac{1}{4}\cdot \cfrac{38}{9}\implies x=\cfrac{11}{2}-\cfrac{19}{18} \n\n\n x=\cfrac{99-19}{18}\implies x=\cfrac{80}{18}\implies \boxed{x=\cfrac{40}{9}}$

Which polygon is a hexagon? A 5-sided figure. A 6-sided figure. An 8-sided figure. A 7-sided figure.

Answers

A 6 - sided figure is called a Hexagon.

What is Line segment?

A line segment is a part of line having two endpoints and it is bounded by two distinct end points and contain every point on the line that is between its endpoint.

Given that;

The polygon is a Hexagon.

Now,

Since, A hexagon is made up with 6 - sided.

And, A polygon is called a Hexagon when it has 6 sides, 6 angles and 6 vertices.

Thus, A 6 - sided figure is called a Hexagon.

Find an equivalent function to f(x) = 5(3)3x.

Answers

f(x) = 5(3)^(3x) = 5(3^(3x)) = 5(27)^x = 5(27)x

The correct result would be f(x) = 5(27)x.

f(x) = 5(3)3x

= 5*3*3*x

= 45x

So an equivalent function is f(x) = 45x

f(x) = 45x

The Mathalot Company makes and sells textbooks. They have one linear function that represents the cost of producing textbooks and another linear function that models how much income they get from those textbooks. Describe the key features that would determine if these linear functions ever intercepted.

Answers

The question is asking to explain or described the key features that would determine if the linear functions is ever intercepted base on the said equation and the function, I would say that the answer would be If two linear equations have different slopes, and are in the same plane, they WILL intersect at ONE point (they will have a unique solution).
