Slope = -2/5, contains the point (10,3)

Daniel [21]

Answer: if this is supposed to be in slope-intercept form

the equation would be: y = -2/5x + 7

Step-by-step explanation:

so the slope is: -2/5 and the point is (10,3) considering that x = 10 and y = 3

so we would plug this information into this equation: y = mx + b (slope-intercept form)

3 = -2/5(10) + b

3 = -4 + b

b = 7

and if we plug this in:

y = -2/5x + 7

mojhsa [17]

Answer: The price of item is $495.

Step-by-step explanation:

Since we have given that

Amount that Sara have = $90

Amount that Rachel have = $405

If they combine their money they will have enough to buy item.

So, Price of item would be

Amount that Sara have + Amount that Rachel have

$=90+405\\\\=\$ 495$

Hence, the price of item is $495.

Which of the following is the product of the rational expressions shown below ? (x + 3)/(x + 2) * (x - 3)/(x - 2)

Molodets [167]

Answer:

Option D : $\frac{x^2-9}{x^2-4}$ is the correct answer.

Step-by-step explanation:

Given rational expression is:

$\frac{x+3}{x+2}*\frac{x-3}{x-2}$

In the first step of solving the rational expression, we will multiply the nominators and denominators.

$\frac{(x+3)(x-3)}{(x+2)(x-2)}$

$\frac{x^2-3x+3x-9}{x^2-2x+2x-4}$

Now we will solve the alike terms.

$\frac{x^2-9}{x^2-4}$

The product of rational expression is $\frac{x^2-9}{x^2-4}$

Hence,

Option D : $\frac{x^2-9}{x^2-4}$ is the correct answer.
