(x-2)(x-5) because -5x-2=10 and -5+-2=-7

In order to solve this, we can multiply out the answer choices and check if they are correct by using FOIL. A would be x^2 + 7x + 12. B would be x^2 - 7x + 12. C would be x^2 - 7x + 10. D would be x^2 + 7x + 10. The answer choice that matches the question is C. (x - 2)(x - 5).

Hope this helps!

In two or more complete sentences, explain how to use ordered pairs of points in x) = 2x + 5 and g(x)=

Naddika [18.5K]

Answer:

see the explanation

Step-by-step explanation:

we have

$A(x)=2x+5$

Find the inverse of A(x)

Let

y=A(x)

$y=2x+5$

Exchange the variables x for y and y for x

$x=2y+5$

Isolate the variable y

$2y=x-5$

$y=\frac{x-5}{2}$

Let

$g(x)=y$

$g(x)=\frac{x-5}{2}$ ------> function inverse of A(x)

<em>Explanation</em>

For x=1

Find the value of A(x)

$A(1)=2(1)+5=7$

The point (1,7) is a solution for A(x)

That means-----> The point (7,1) is a solution for the function inverse g(x)

Verify

For x=7

$g(7)=\frac{7-5}{2}=1$

The point (7,1) is a solution for g(x)

therefore

A(x) and g(x) are inverses of each other if the point (x,y) is a solution of A(x) and the point (y,x) is a solution of g(x)

The price of a cup of coffee was $2.75 yesterday. Today, the price fell to $2.40. Find the percentage decrease. Round your answe

Fed [463]

Answer: (2.75-2.40)/(2.75) * 100 [Before rounding to the nearest tenth]

Step-by-step explanation:

Formula for percentage decrease = (old-new)/(old) * 100

so substituting in, you get (2.75-2.40)/(2.75) * 100

From here, you can just plug this into a calculator (don't have on me rn)

son4ous [18]

Answer:

48.75

Step-by-step explanation:

The salesmen makes a commission of 3.25%. So to get the percent into a usable form for this take 3.25 and divided by 100. You get 0.0325.

Now you take the 0.0325 and mutliply it by the 1500. This gives you 48.75
