Is 2.5 : 8 and 7.5 : 24 equivalent?

Answer:

y = -4x-15

Step-by-step explanation:

y = ax+b

-19=a+b

-7=-2a+b

==> a = -4

b = -15

Answer:

There is only 1 solution

[tex](x,y) = (1,4)[/tex]

Step-by-step explanation:

Given

Lines A and B

Required

The number of solution for a pair of A and B

From the graph, lines A and B have only one point of intersection.

This point of intersection represents the solution

Since, there is only 1 point, there is only one solution.

And the solution is:

[tex](x,y) = (1,4)[/tex]

Answer:

18a^3b^2/2ab

To simplify the given expression, we apply property of exponents

18/2 = 9

x^m / x^n= x^ (m-n) In division we subtract the exponents

So given expression becomes

9a^2b

The answer has only positive exponents

i think this is what you want?

The simplified exponential notation of the given expression is [tex]9a^2b[/tex].

The given expression is: [tex]\frac{18a^3b^2}{2ab}[/tex]

An expression in the form of [tex]a^pb^qc^r[/tex].. is called exponential expression.

We can write the above expression as:

[tex](\frac{18}{2} )(\frac{a^{3} }{a} )(\frac{b^{2} }{b} )[/tex]

We know that [tex]\frac{a^m}{a^n} =a^{m-n}[/tex]

[tex]\frac{a^{3} }{a} =a^{3-1} =a^{2} \\\frac{b^{2} }{b}=b^{2-1} =b[/tex]

So, [tex](\frac{18}{2} )(\frac{a^{3} }{a} )(\frac{b^{2} }{b} )[/tex] =[tex]9a^2b[/tex]

Hence, the simplified exponential notation of the given expression is [tex]9a^2b[/tex].

Answer:

  D  There is an infinite number of solutions to the system of equations

Step-by-step explanation:

When you put the first equation in standard form by dividing it by 2, you get ...

  x -2y = 4

When you put the second equation in standard form by dividing it by 8, you get ...

  x -2y = 4

These are the same equation, so describe the same line. There are an infinite number of (x, y) pairs that will satisfy this equation.

There is an infinite number of solutions.

Answer:

x = 16

Step-by-step explanation:

x/4 - 1 = 3

x/4 = 3+1

x/4 = 4

x = 4*4

x = 16

Answer:

x=16

Step-by-step explanation:

always multiply denominator by whatever it is to the number behind the equl sign after subtracting that one it would be whatever that number is *4

Answer:

156.6 meters squared

Step-by-step explanation:

There are 3 triangles for the sides. The area for a triangle is one half base times height. So we are doing one half of 9 times 9. This is 40.5. Since there are 3 of them we can just multiply 40.5 times 3 to get 121.5. And now to solve for the base triangle, it is one half of 9 times 7.8. We get 35.1. Now add together 121.5 and 35.1. We get 156.6. Now since this is surface area it is meters squared.
