y = 4x-9

Answer : Slope = 4 because y = mx+b

Y- intercept = 9

Any line can be graphed using two points values, and plug them into the equation to find the corresponding values.

If for a particular one-to-one function f(2) = 13, what are the corresponding input and output

maks197457 [2]

Answer:

$f^{-1}(13) = 2$ .

Step-by-step explanation:

For function $f$ , the notation $f(2) = 13$ means that when the input to the function is $2$ , the output would be $13$ .

The inverse function of a one-to-one function $f$ is commonly denoted as $\!f^{-1}$ .

The inverse function undoes the action of the original function. In this question, $f$ maps $2$ to $13$ . Thus, $f^{-1}$ would need to map $13\!$ back to $2\!$ . Therefore, $f^{-1}(13) = 2$ should be the corresponding input and output values.

Please help me figure this out

Gnom [1K]

Answer:

True

(1) You can prove two triangles are similar using AA similarity.

(2)If side length of similar figure have ration $\frac{m}{n}$ then the ratio of surface areas will be: $\frac{m^2}{n^2}$

(3)If side length of similar figure have ratio of $\frac{2}{3}$ then perimeter will have ratio: $\frac{2}{3}$ .

False:

(1)If side length of similar figure have ration $\frac{m}{n}$ then the ratio of Volumes will be: $\frac{m^3}{n^3}$

(2)If side length of similar figure have ration $\frac{m}{n}$ then the ratio of surface area will be: $2\frac{m}{n}$

Complete the square for the expression, then factor the trinomial.

Nuetrik [128]

Answer:

Completing the square we get: $(x-2)^2-(2)^2$

and factoring the term we get: $x(x-4)$

Step-by-step explanation:

We need to complete the square for the expression $x^2-4x$

For completing the square the expression would be of form $a^2+2ab+b^2=(a+b)^2$

For given expression we have to add (2)^2 and subtract to make it complete the square.

$x^2-2(x)(2)+(2)^2-(2)^2\\(x-2)^2-(2)^2$

Now, we have to factor the polynomial using formula $(a)^2-(b)^2=(a-b)(a+b)$

So, $(x-2)^2-(2)^2\\=(x-2-2)(x-2+2)\\=(x-4)(x-0)\\=x(x-4)$

Completing the square we get: $(x-2)^2-(2)^2$

and factoring the term we get: $x(x-4)$
