Thomas and Silvia are brother and sister. Thomas is 12 years older than Silvia and their combined ages are 44. How old are Thomas and Silvia?


show work please

Answers

Answer 1
44 divided by 2 is 22, then subtract 12 from that, which is 10.

so in conclusion, thomas is 22 and silvia is 10

but that answer is wrong.

44 minus 12 is 32, now divide 32 by 2 and you get 16.

so this would mean that thomas is 32, and silvia is 16, but that doesn’t add up either.

The graph shows the function f(x) = x^2 in blue and another function g(x) in red. which of the following could the equation for g(x)?

Answers

you didn’t post the picture buddy boi

g(x)=1/5x² is the equation for blue graph.

What is Graph?

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

The equation of the red quadratic graph is f(x)=x²

This is the parent quadratic function or the base of the quadratic functions.

This red quadratic graph has been dilated by a certain scale factor  to obtain the blue graph.

Recall that, when the scale factor is a fraction, such that 0<k<1 the graph is stretched horizontally.

The dilated graph then becomes wider than the parent function.

From the given function equations, the possible value of k can only be k=1/5

Therefore the blue graph has equation g(x)=1/5x²

Hence, g(x)=1/5x² is the equation for blue graph.

Answer:

C(90) = 15.35

Step-by-step explanation:

Given the function, C(n) = 0.06n + 9.95:

where C = total cost of texting plan

Mia is solving the equation x2 – 12x = 1. Which value must be added to both sides of the equation to make the left side a perfect-square trinomial?


9


-9


36


8

Answers

The value to be added to both sides of the equation to make the left side a perfect square trinomial is; -36.

To make the equation x2 – 12x = 1 look similar to the completing the square kind of expression where the left hand side of the equation becomes a perfect square, we must do the following;

First, the completing the square method usually takes the form;

+ bx = (x + b/2)² + c

In this scenario, the term (x² - 12x) can be rewritten as; (x - 6)² - 36.

This so because the expansion of (x - 6)² becomes;

x² - 12x + 36.

Therefore, there's a need to subtract 36 from both sides of the equation so that the equation x2 – 12x = 1 is retained.

Therefore, the value to be added to both sides of the equation to make the left side a perfect square trinomial is; -36.
