Answer:x = 12,5

using thales's theorem, we have:

\frac{15}{15+36}=\frac{20}{6x-7}\\\\ 6x-7=\frac{20.(15+36)}{15}=68\\\\x = \frac{68+7}{6}=12.5

Brad says that if a second number is 125% of the first number than the second number must be 75% of the second number is he corr
elena-s [515]

Answer:

Incorrect.

Step-by-step explanation:

Let, the first number is x, and the second number is y. Given, the second number is 125% of the first number. So, the equation will be

y = 1.25 x

Or, y= 5/4x

Now, multiplying it with 4/5, we get, x= 4/5y

Or, x= 0.80 y

But, Brad is saying the first number must be 75% of the second number. But here we see that the first number is 80% of the second number. That's why Brad is incorrect.

Pleaseee helppp I don't understand thissd
Bess [88]

Very simple.

Let's say you have an equation.

f(x) = x^2

You are asked to find the value for y when x equals 1.

The new equation is: f(1) = (1)^2

f(1) = 1

When x = 1, y = 1.

The same concept is applied here.

In the graph, where does x equal 0?

It equals zero at the origin.

Is there any y-value associated with 0?

Yes, there is.

Y equals five when x equals 0.

So

h(0) = 5
