notka56 [123]

Answer:

-5 If it is one of your answers it will be -5

Step-by-step explanation:

If you take 10 and have 3 decrease every minute and did it for 5 minutes it will go 10 7 4 1 -2 -5 That is 5 minutes of the temperature decreasing by 3 I hope it is right.

A 85 inch piece of pipe is cut into three pieces, so that the second

nikdorinn [45]

Answer:

Step-by-step explanation:

x 2x 3x + 1

|---------|-------------------|---------------------------|

|<-------------------- 85 in ------------------------>|

85 = x + 2x + 3x + 1

85 - 1 = 6x

x = 84 / 6

x = 14

1st piece = 14 in

2nd piece = 2(14) = 28 in

3rd piece = 3(14) + 1 = 43 in

----------------------------

total = 85 in

Given the functions f(x)= 1/x−4 +3 and g(x)=1/x+1 +6 .

melomori [17]

ANSWER

The graph shifts 5 units left and 3 units up.

EXPLANATION

The given functions are:

$f(x) = \frac{1}{x - 4} + 3$

and

$g(x) = \frac{1}{x + 1} + 6$

We want to transform f(x) so that, it coincide with the g(x).

The required transformation is

$f(x+5)+3$

Let us see why this works.

$f(x+5)+3 = \frac{1}{x + 5- 4} + 3 + 3$

$f(x+5)+3 = \frac{1}{x + 1} + 6 = g(x)$

The transformation f(x+5)+3 will shift f(x) 5 units left and 3 units up.

The third choice is correct.

Solve the following quadratic equation by the square root method. (Y-9)^2=64

enot [183]

Hello!

To solve this, first perform the opposite operation for the last operation (on the left side) on both sides. The last operation of the left side is squaring. Therefore, square root both sides.

$(y - 9)^{2} = 64$

$y - 9 = ±\sqrt{64}$

$y - 9 = ±8$

Please note that you must include ±. This is because the square root of 64 can be either positive or negative, as a square of either a positive or negative number is positive.

Now, add 9 to both sides.

$y = 9±8$

There are 2 solutions from here. One comes from adding 8, and the other subtracting 8. Therefore, the two solutions are:

y = 9 + 8 = 17

y = 9 - 8 = 1

Therefore, your two solutions are 17 and 1.

Hope this helps!
