So y=mx+b
m=slope

y=-3x+b
subsitutue 1 for x and 4 for  y
4=-3(1)+b
4=-3+b
add 3 to both sides
7=b

the equaiton is y=-3x+7

Paraphin [41]

Answer:

Sin A = 15 / 17

Step-by-step explanation:

Given a right angled triangle, we are to obtain the Sin of the angle A ;

Using trigonometry, the sin of the angle A, Sin A is the ratio of the angle opposite A to the hypotenus of the right angle triangle.

Hence. Sin A = opposite / hypotenus

Opposite = 15 ; hypotenus = 17

Sin A = 15 / 17

.John has $40. He will use some of the money to buy books, and he wants to have at least $10 left to put in his savings account.
Crank

Answer:

The required inequality is 40-6b\leq 10.

Jhon can buy at most 5 books.

Step-by-step explanation:

Consider the provided information.

Part(A)

Let b represent the number of books John buys.

He wants at least $10 in his savings account which means if we subtract the cost of books from $40 we have at least $10 left.

40-6b\leq 10

The required inequality is 40-6b\leq 10.

Part(B)

40-6b\leq 10

-6b\leq 10-40

b \leq\frac{30}{6}

b\leq 5

Part(C):  Jhon can buy at most 5 books.
