Answer:

18-26i

Step-by-step explanation:

hope this helps :)

We have to find b

[tex]\\ \sf\longmapsto y=mx+b[/tex]

[tex]\\ \sf\longmapsto -1=\dfrac{-2}{3}(-3)+b[/tex]

[tex]\\ \sf\longmapsto -1=-2(-1)+b[/tex]

[tex]\\ \sf\longmapsto -1=2+b[/tex]

[tex]\\ \sf\longmapsto b=-3[/tex]

Now put in equation

[tex]\\ \sf\longmapsto y=\dfrac{-2}{3}x-3[/tex]

Answer:

5+4(-20)

Step-by-step explanation:

So you do the one's in parentheses first, which is -20, and then you do 5+4  which is 9

Answer:

I really don't know but good luck

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

1.25/12 = ~.10

Answer:

Step-by-step explanation:

To solve for x you have to move the -5y to the other side of the equals sign.  Since the opposite of subtracting is adding, we will add 5y to both sides to get

x = 5y + 6

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.

Hey there! :)

[tex]\frac{23}{24} *\frac{34}{56}[/tex]

Let's reduce our fraction:

We can divide 24 and 34 by 2:

[tex]\frac{23}{12} *\frac{17}{56}[/tex]

Now it's a little easier. All we have to do is multiply 23 times 17 and 12 times 56.

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
