Answer: y = -1/4 * x - 4

Explanation:
Slope intercept form : y = mx + b
m = slope & b = y intercept
y = mx + b
y = -1/4(x) + b
y = -1/4(x) - 4

-1/4 is slope
-4 is y intercept

Find the slope of the line that passes through the pair of points (6,-2) and (5,-4).
Show all work necessary and write your final answer in the box.

Answers

Answer:

slope = -10/7

Step-by-step explanation:

co-ordinates = (6,-2) (5,-4)

slope = (y² - y¹) / (x² - x¹)

slope = (-4 - 6) / (5 - (-2))

slope = (-10) / (5+2)

slope = (-10) / 7

slope = -10 / 7

3(1 - 2a) = -3a - 18

Answers

Answer:

a = 7

Step-by-step explanation:

3(1 - 2a) = -3a - 18

3 - 6a = - 3a - 18

Add 18 to each side:

3 + 18 - 6a = - 3a - 18 + 18

21 - 6a = - 3a

Add 6a to each side:

21 - 6a + 6a = - 3a + 6a

21 = 3a

3a = 21

Divide each side by 3:

3a ÷ 3 = 21 ÷ 3

a = 7

If the sales tax rate is 8.2% in California, then how much would you pay in Los Angeles
for a pair of shoes that cost $39.00?

Answers

Answer:

$42.22

Step-by-step explanation:

The sales tax rate = 8.25 = 0.0825  [Divide by 100 to convert in decimal]

The cost of a pair of shoes = $39.00

Tax amount to pay = Tax rate × Cost of a pair of shoes

Now, the total amount you pay for a pair of shoes = Cost of a pair +Tax amount

= $39.00+$ 3.22

Total Price:$ 42.22

You are kayaking along a 24-mile stretch of river. You travel 6 miles per hour when paddling and 2 miles per hour when drifting. Give three possible combinations of paddling and drifting times. Write your answers as ordered pairs.

Answers

Answer:

(1,6), (2,6), (3,3)

Step-by-step explanation:

Since you  travel 6 miles per hour when paddling and 2 miles per hour when drifting, and the total distance covered is 24 miles, we find the times t and t' of paddling and drifting respectively in which the product 6t + 2t' = 24.

So, for the first values of t and t' , we have t = 1 and t' = 9

So, 6t + 2t' = 6 × 1 + 2 × 9 = 6 + 18 = 24

As an ordered pair (1, 9)

For the second set of values of t and t' , we have t = 2 and t' = 6

So, 6t + 2t' = 6 × 2 + 2 × 6 = 12 + 12 = 24

As an ordered pair (2, 6)

For the third set of values of t and t' , we have t = 3 and t' = 3

So, 6t + 2t' = 6 × 3 + 2 × 3 = 18 + 6 = 24

As an ordered pair (3, 3)

So, the three different combinations of paddling and drifting times are (1,6), (2,6), and (3,3)

On one island there lived two friends, Ana and Banana. One of them always tells the truth, while the other always lies. When asked which one is the liar among them, they said: Ana: "Banana ate ten apples yesterday, and he is telling the truth." Banana: "No, I ate five apples yesterday, and Ana is lying." How many apples did Banana eat yesterday?

Answers

Answer:

Number of apples ate = 5

Step-by-step explanation:

Fact:

One of them always tells the truth, while the other always lies.

To find how many apples banana ate, we have to figure out who is lying between Ana and Banana.

Ana: "Banana ate ten apples yesterday, and he is telling the truth."

If Ana is telling the truth, that means Banana is also telling the truth because of the statement (... and he is telling the truth).

This is not possible as one of them must be lying. The only option left is that Ana is lying.

Since Ana is lying, it means banana is telling the truth.

Banana: "No, I ate five apples yesterday, and Ana is lying."

Number of apples ate = 5
