Please answer. Thanksss

No, No, Yes, Yes

Step-by-step explanation:

We can simply substitute the pairs as x and y in the equation:

(5, 0)

7*5 + 5*0 = 35 + 0 = 35

(-4, -3)

7*(-4) + 5*(-3) = -28 - 15 = -43

(2, -1)

7*2 + 5*(-1) = 14 - 5 = 9

(-3, 6)

7*(-3) + 5*6 = -21 + 30 = 9

step-by-step explanation:

fabric (square meters)                   cloaks

7                                                           21

4/3                                                         4

step-by-step explanation:

we are told that harry needs 2 square meters of fabric for every 6 wizard cloaks he makes.

1. first of all we will find how many cloaks can be made from 1 square meter of fabric by dividing 6 by 2.

we can see that 3 cloaks can be made from 1 square meter of fabric. now we will multiply 3 by 7 to find number of cloaks made from 7 square meters of fabric.

therefore, harry will make 21 cloaks from 7 square meters of fabric.

2. let us find how many square meters of fabric will be needed to make 4 cloaks.

first of all we will find fabric needed for 1 cloak by dividing 2 by 6.

we can see that fabric needed for 1 cloak is   square meter. now we will multiply   by 4 to find fabric needed for 4 cloaks.
