First:Add 2 to the -9 to get -7
Next: Then multiply the -7 by 9 to get -63 but remember that you have to flip the sign when you divide or multiply
Lastly: The answer is -63 is greater than K

Multiplication
Division
Addition
Subtraction

Left to Right

Step-by-step explanation:

<u>Step 1: Define</u>

2x³y³ + 3xy - 3x³y³ + x²y - xy + 2x²y

x = -1

y = 2

<u>Step 2: Evaluate</u>

Substitute: 2(-1)³(2)³ + 3(-1)(2) - 3(-1)³(2)³ + (-1)²(2) - (-1)(2) + 2(-1)²(2)
Exponents: 2(-1)(8) + 3(-1)(2) - 3(-1)(8) + 1(2) - (-1)(2) + 2(1)(2)
Multiply: -16 - 6 + 24 + 2 - (-2) + 4
Simplify: -16 - 6 + 24 + 2 + 2 + 4
Subtract: -22 + 24 + 2 + 2 + 4
Add: 2 + 2 + 2 + 4
Add: 4 + 2 + 4
Add: 6 + 4
Add: 10

Explain how you can find 4 × 754 using two different methods

Nataly_w [17]

Method 1:

4(754)

=4(700+50+4)

=2800 + 200 + 16

=3000+16

=3016

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

Method 2:

4(754)

=4(250+250+250+4)

=1000+1000+1000+16

=3016

Zander was given two functions: the one represented by the graph and the function f(x) = (x + 4)2. What can he conclude about th

Julli [10]

The conclusion about the functions is they have the same y-intercept.

<h3>How to make conclusion about the functions?</h3>

The complete question is added as an attachment

The function is given as:

f(x) = (x + 4)^2

From the attached graph, the graph has a y-intercept at:

y = 16

This can be represented as:

(0, 16)

Next, we set x = 0 in f(x) = (x + 4)^2

f(0) = (0 + 4)^2

Evaluate

f(0) = 16

This means that the y-intercept of f(x) = (x + 4)^2 is (0, 16)

So, the functions have the same y-intercept

Hence, the conclusion about the functions is they have the same y-intercept.
