Answer:

y = 7/5x + 4

Step-by-step explanation:

use the slope from the equation -5/7 and take the negative reciprocal to get the perpendicular slope = 7/5. Then use the equation y=mx+b. Plug in x and y from the point given and the new slope and solve for b.

(-3) = (7/5)(-5) + b, (-3) = -7 + b, add 7 to both sides. b = 4. Rewrite the equation now to be y = 7/5x + 4

Name an object that could be about the same length as each measurement. A. 4 inches b. 6 feet c. 1 meter d. 5 yards a. 6 centime

Nastasia [14]

Answer and Step-by-step explanation:

A. 4 inches: An object that's 4 inches is about 2.54 centimeters or 25.4 millimeters. An business envelope is typically about 4 inches by 9 inches for example.

B. 6 feet: A 6 feet object is quite big when compared to just 4 inches. A feet is 12 inches hence 6 feet is 72 inches. A very tall human being is typically 6 feet.

C. 1 meter: A meter is about 39.37 inches hence it is quite big when compared to a feet. A baseball bat is one meter long.

D. 5 yards: A yard is 36 inches hence a bit smaller than a meter. A trampoline could be 5 yards for example

E. 6 centimeters: one centimeter is 0.394 inches hence smaller than an inch. A 6 centimeters object for example is pencil for writing.

F. 2 millimeters: a millimeter is 0.0394 inches hence smaller than a centimeter and an inch. An orange seed could be 2 millimeters long

G. 3 kilometers: one kilometer is 39370.079 inches hence a kilometer is bigger than inches, meter, feet, yards, centimeters, millimeters. A very big tree could be 3 kilometers long

Bob is buying coffee for his coffee machine.Option 1 is $5.99 for 12 coffeesOption 2 is 23.99 for 70 coffee Which is the better

velikii [3]

Step 1: Let's review the information provided to us to answer the problem correctly:

• Option 1: $5.99 for 12 coffees

• Option 2: $ 23.99 for 70 coffee

Step 2: Let's calculate the cost of a coffee in each option, as follows:

• Cost of a coffee in Option 1 = 5.99/12 = 0.50 (rounding to the next cent): This means that every cup of coffee costs $ 0.50

• Cost of a coffe in Option 2 = 23.99/70 = 0.34 This means that every cup of coffee costs $ 0.34

Step 3: Now we can decide which is the better deal and why.

The better deal is option ........ because it is cheaper than option..........

You can complete step 3, Kay.

Look for a pattern in the first three diamonds below. For the fourth diamond, explain how to find the missing numbers (?) if you

murzikaleks [220]

The general pattern that these diamonds follow is that the top number is the result of multiplying the numbers in the middle; while the bottom number results from adding these numbers. This pattern can be used to find the numbers in the fourth diamond. Moreover, the numbers that complete the diamonds are A (15,8), B (2,-3), C (4,2), D(4,8.5), E (-3.-4)

<h3>What is the general pattern in the diamonds?</h3>

Based on observation, you can determine in these diamonds the top number is obtained by multiplying the numbers in the middle, while the bottom number is obtained by adding these numbers.

<h3>What numbers complete the diamonds?</h3>

Diamond A

Top number: 15 (3x5)

Bottom number: 8 (3+5)

Diamond B

Top number: 2 (-2x-1)

Bottom number: -3(-2+-1)

Diamond C

4, 2 because 4x2 = 8 and 4+2 = 6

Diamond D

Top number: 4( 8x0.5)

Bottom number: 8.5(8+0.5)

Diamond E

-3,-4 because -3x-4= 12, and -3+-4= -7
