Explain how multiply or divide two integers with the same sighn and and with diffrent sighns

Mathematics
1 answer:
hoa [83]3 years ago
5 0

Multiplying and dividing integers with the same sign and different signs.

When multiplying and dividing with the same sign, the answer will always be positive.

6/3 = 2

-6*-3=18 (Two negatives make a positive)

-4/-2=2 (This is because there are two -2s in -4, so the answer will always be positive- also two negatives make a positive.)

When multiplying and dividing by different signs, the answer will always be negative.

3*-6= -18

4/-2 = -2

Because the answer will always by negative, you can multiply or divide normally and then just add the negative sign (-) in front of the answer.

Lindy works at a pizza restaurant and gets a 10% employee discount. She knows that if she orders d drinks and a medium pizza wit
timofeeve [1]

Answer:

$17.28.

Step-by-step explanation:

In the expression, d represents the number of drinks she orders and t represents the number of toppings.

In this case, she orders 4 drinks and 3 toppings, so d = 4 and t = 3.

0.90(2.25d + 1.40t + 6)

= 0.9(2.25 * 4 + 1.4 * 3 + 6)

= 0.9(9 + 4.2 + 6)

= 0.9 * 19.2

= 17.28

So, the total cost for Lindy and her friends will be $17.28.

Hope this helps!

Y+5=2(x+1) find x and y intercepts
Andrej [43]

The x and the y intercept are x = 1.5 and y = -3

<h3>How to determine the x and the y intercept?</h3>

The linear equation is given as:

y + 5 = 2(x + 1)

Set x to 0 to determine the y-intercept.

So, we have:

y + 5 = 2(0 + 1)

This gives

y + 5 = 2

Evaluate

y = -3

Set y to 0 to determine the x-intercept.

So, we have:

0 + 5 = 2(x + 1)

This gives

5 = 2(x + 1)

Evaluate

x = 1.5

Hence, the x and the y intercept are x = 1.5 and y = -3

Does the point (–1, 1) satisfy the equation y = 4x + 5?
sveta [45]

Answer: True

Step-by-step explanation:

Substitute -1 for x and 1 for y in the equation y = 4x + 5

(1) = 4(-1) + 5

1 = -4 + 5

1 = 1

Left side = right side

Therefore,  the point (–1, 1) satisfies the equation y = 4x + 5
