X=-2 so you have to get x alone which you subtract 7 from 5. You take the seven and subtracted it to the left side, which leaves -2 and that’s your answer

Answer X= (-2)

Step-by-step:

5-x = 7
-x = 7-5
-x = 2
So x = -2

Which answer is an equation in point-slope form for the given point and slope?
Point: (5, 9); Slope: 2
y-5= 2 (2 +9)
y-9=2(x+5)
y+9= 2(2-5)
y-9=2(x – 5)

Answers

Answer: y-9=2(x-5)

Step-by-step explanation: The point (5,9) satisfies the equation:

y-9=2(x-5) for (5,9)?

9-9=2(5-5) ?

0 = 0 YES

Slope of 2? Rewrite:

y-9=2(x-5)

y = 2(x-5)+9

The slope is 2 YES

a 24
b 48
c 16
d 42

Answers

Answer:

it is C 16

Step-by-step explanation:

x² - kx + 64

Since we are looking for a perfect square, then we need to take the square root of 64 to find the factors: √64 = 8

So, the factors are: (x - 8)(x - 8)

Foil (or distribute) to get: x² - 16x + 64 The k-value is 16

Write this polynomial in descending order. Enter exponents using the caret
(). For example, enter x2 as x^2.
-7 + 8x2 - 4x

Answers

Answer: 8x^2 -4x -7

Step-by-step explanation: the x^2 term comes first, followed by the x, then the constant which in this case is -7

so it would be 8x^2 -4x -7

The polynomial -7 + 8x² - 4x written in descending order is 8x² - 4x - 7.

To write the polynomial -7 + 8x² - 4x in descending order, we arrange the terms from highest degree to lowest degree.

Here's how to do it step by step:

Step 1: Identify the degree of each term:

The term -7 has a degree of 0 (since it is a constant).

The term 8x² has a degree of 2 (since it has a variable raised to the power of 2).

The term -4x has a degree of 1 (since it has a variable raised to the power of 1).

Step 2: Arrange the terms in descending order based on their degrees:

Start with the term with the highest degree and proceed in decreasing order. In this case, we have only three terms, so we start with the highest degree term:

8x² (degree 2)

Next, we consider the next highest degree term:

-4x (degree 1)

Finally, we have the constant term:

-7 (degree 0)

Step 3: Write the polynomial in descending order:

Putting the terms together in descending order, we have:

8x² - 4x - 7

So, the polynomial -7 + 8x² - 4x written in descending order is 8x² - 4x - 7.
