Step-by-step explanation:

if 6 exhibits are 25% of the entire zoo. You would need four times that amount to get the total number of exhibits because 25% × 4 = 100%. So, if you multiply 6 × 4 the total number of exhibits would be 24.

Answer:

Yes , Avery is correct

Step-by-step explanation:

To check if Avery is correct, we need to know the exact value obtained in each of their goals

For Avery’s team;

3/5 * 450 = $270

For Nolan’s team

5/9 * 450 = $250

Since $270 is greater than $250, we can see that Avery’s team collected more money

Answer:

45/4 I think

Step-by-step explanation:

you would do keep flip switch

so 5 would be 5/1, flip 4/9 to become 9/4 then multiply 5/1 by 9/4

hopefully this helps you

Answer:

1) slope m=-4

2) slope m=-5/4

3) slope m=1

4) slope m=-2

5) slope m=3/5

6) slope m=5/8

Step-by-step explanation:

Slope equation: m=y2-y1/x2-x1

With our slope equation can get just use the graph and choose two points that the line crosses over.

Question 1 example) I chose points (0,-3) as my x1, y1, and point (1,-1) as my x2, y2. I plugged the numbers into the equation and got -1-3/1-0=-4. Which is why our slope is -4

The rest of the questions follow the same concept of Finding two points, decide which one is your x1, y1 and which one is you x2, y2 (does not matter which one you associate with each point), plug the numbers in, and calculate the slope.

(I may be wrong because the graph is a little blurry)

Answer:

Negative

Step-by-step explanation:

Because Depending on which number is the biggest it's negative and the rules say the same signs add different subtract and keep the sign of the bigger number so

positive minus a negative= positive (6-3=3)

negative-positive= negative (-10+5= -5)

Example: What is 6 − (−3)? Yes indeed! Subtracting a negative is the same as adding!

Answer:

{-14, -2, 10}

Step-by-step explanation:

To find the range, you can use all the domain values and find the output.

f(-4) = 3(-4) - 2

f(-4) = -12 - 2

f(-4) = -14

f(0) = 3(0) - 2

f(0) = 0 - 2

f(0) = -2

f(4) = 3(4) - 2

f(4) = 12 - 2

f(4) = 10

Best of Luck!

Step-by-step explanation:

Answer: d, (3+5i)-(2+i)

Step-by-step explanation:

i’m smart

The subtraction expression that has the difference 1 + 4i is (3 + 5i) - (2 + i).

Option D is the correct answer.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

We can find the difference 1 + 4i by subtracting the complex numbers in each expression and checking which one gives us the result of 1 + 4i.

Let's start with option (a):

(-2 + 6i) - (1 - 2i) = -2 + 6i - 1 + 2i = -3 + 8i

This is not equal to 1 + 4i, so option (a) is not the correct answer.

Let's move on to option (b):

(-2 + 6i) - (1 - 2i) = -2 + 6i - 1 + 2i = -3 + 8i

We have already seen this expression and it is not equal to 1 + 4i. Therefore, option (b) is also not the correct answer.

Let's move on to option (c):

(3 + 5i) - (2 - i) = 3 + 5i - 2 + i = 1 + 6i

This is not equal to 1 + 4i, so option (c) is not the correct answer.

Finally, we have the option (d):

(3 + 5i) - (2 + i) = 3 + 5i - 2 - i = 1 + 4i

This is equal to 1 + 4i.

Thus,

The subtraction expression that has the difference 1 + 4i is (3 + 5i) - (2 + i).

Answer:

5:1

Step-by-step explanation:

The ratio 10: 2 will be equivalent to ratios 20:4, 30:6, 40:8, and 50:10. Then all the options are correct.

A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.

The equivalent is the expression that is in different forms but is equal to the same value.

The ratio is given below.

Ratio = 10 / 2

Multiply and divide the ratio by 2. Then we have

Ratio = 10 x 2 / 2 x 2

Ratio = 20 / 4

Multiply and divide the ratio by 3. Then we have

Ratio = 10 x 3 / 2 x 3

Ratio = 30 / 6

Multiply and divide the ratio by 4. Then we have

Ratio = 10 x 4 / 2 x 4

Ratio = 40 / 8

Multiply and divide the ratio by 5. Then we have

Ratio = 10 x 5 / 2 x 5

Ratio = 50 / 10

The ratio 10: 2 will be equivalent to ratios 20:4, 30:6, 40:8, and 50:10. Then all the options are correct.
