Just replace x by its new value (a+2)
f(x) = (3+x) / (x-3) ==> [3+(a+2) / (a+2) -3] ==> (5+a) / (a-1) . Answer B

X-y=3 in slope intercept form and find x and y intercepts​
Dominik [7]

Answer:

x intercept is x=3

y intercept is y=-3

Step-by-step explanation:

We can write this equation in a simpler way to find the values needed. Lets do it. Take:

x-y=3

And sum y in both sides, as we know the equality will maintain:

x-y+y=3+y

x = 3+ y

Now subtract 3 in both sides:

x-3 = y+3-3

x-3=y

So, we can rewrite our equation as y=x-3

The x intercept is a value of x such that the equation in equal to zero; in other words, is the value of x when y is zero. It is also called a zero root. Graphically, its the x value when the function passes trough the x-axis. Lets find if, we nned that:

x-3 = 0

If we sum 3 in both sides:

x-3+3=3

x=3

So, x=3 is x intercept

For finding the y intercept we need the value of y when x is zero. Graphically, is the value of y obtained when the function passes trough the y-axis. So, replace x with 0:

0-3=y

y=-3

Another way to get it is knowing that the y intercept in a polynomial is always the independent term, the one that has no x or y, which in this case is -3.

Answer 1. And 2.for Brainliest
Alekssandra [29.7K]

Answer:

Step-by-step explanation:

10% discount means you pay 90% of the original cost x.

90% of x = $40.50

0.90x = $40.50

x = $40.50/0.90 = $45

:::::

total cost = 1.065·$40.50 ≅ $43.13

When two of the three numbers are added at a time, the possible sums are 32, 39, 23. What is the sum of all three numbers?
arsen [322]

Answer:

47

Step-by-step explanation:

Let a, b, and c be those three numbers.

When two of the three numbers are added at a time, the possible sums are 32, 39, 23. Let

a+b=32\\ \\a+c=39\\ \\b+c=23

Add these three equations:

a+b+a+c+b+c=32+39+23\\ \\2a+2b+2c=94

Divide this equation by 2:

a+b+c=47

The sum of all three numbers is 47.

Solve for v.<br><br> 14 − 10v + 11 = 20v + 5(–7v − 11)<br><br> v =
AlexFokin [52]

Answer:

v = -16

Step-by-step explanation:

<u>→Distribute the 5 to (-7v - 11):</u>

14 - 10v + 11 = 20v - 35v - 55

<u>→Add like terms:</u>

25 - 10v = -15v - 55

<u>→Add 15v to both sides:</u>

25 + 5v = -55

<u>→Subtract 25 from both sides:</u>

5v = -80

<u>→Divide both sides by 5:</u>

v = -16
