How many solutions do the TWO equations have?

Mathematics

1 answer:

Nadya [2.5K]3 years ago

7 0

Answer:

Below.

Step-by-step explanation:

15y + 12x = 18

5y + 4x = 6

The second equations is the first times 3 so they are basically the same.

Infinite Solutions.

2x+ 3y= 12

-6y= 4x-24 Rearranging the second equation:

-4x - 6y = -24 Multiplying the first equation by 2:

4x + 6y = 24

- we see that the last equation is -1 * previous equation.

So there are infinite solutions.

A maps key shows that every 5 inches on the map represents 200 miles of actual distance. Suppose the distance between two cities

ryzh [129]

Hello there, and thank you for posting your question here on brainly.

Short answer: 280 miles.

Why?

You can find this out by finding out how much 1 in is by dividing 200 by 5. (200 / 5 ==> 40) So 1 in = 40 miles. Now, we multiply that by 7, so we can find out how much 7 in would be. (7 * 4 ==> 280) 7 inches on the map represents 280 miles.

Hope this helped you! ♥

Number 2 says Write the given equation in exponential form. Log8 1/512=-3

MA_775_DIABLO [31]

In exponential form it is given as, 8⁻³ = $$\frac{1}{512}$

Step-by-step explanation:

We have to write the given equation in the exponential form, that is in the form of base to the power value.

Given:

log₈ ( $$\frac{1}{512}$ ) = -3

Here the base is 8.

In the exponential form, it is written as,

base to the power 3 = 512

Here the reciprocal of 512 is given, so,

base to the power -3 = $$\frac{1}{512}$

So the exponential form is given as, 8⁻³ = $$\frac{1}{512}$
