Use the 2 dots on the line located at (0,1) and (-3,0).

The slope is the change in Y over the change in X:

Change in Y = 0-1 = -1

Change in X = -3 - 0 = -3

Slope = -1 / -3 = 1/3

They intercept in this case is Y1 which = 1.

The equation is y = 1/3x + 1

A scuba diving resort hotel offers divers two plans. Plan A gives 3 nights’ lodging and 4 dives. Plan B gives 5 nights’ lodging

Marizza181 [45]

Answer:

x = 35 and y = 100

Step-by-step explanation:

Let x = dollar cost per dive and y = dollar cost per night.

ATQ,

4x+3y = 440 .....(1)

and

8x + 5y = 780 .....(2)

Multiply equation (1) by 2.

8x+6y = 880......(3)

Subtract equation (3) from (2).

8x + 5y -(8x+6y)= 780-880

-y = -100

y = 100

Put the value of y in equation (1).

4x+3(100) = 440

4x = 440-300

4x = 140

x = 35

Hence, the value of x is 35 and that of y is 100.

Two consecutive integers whose product is 56

Iteru [2.4K]

≡ We know that:
⇔ Consider the first integer is $a$
⇔ So, the next integer is $(a+1)$

≡ Solution:
⇒ $(a).(a+1)=56$
⇒ $a^{2}+a=56$
⇒ $a^{2}+a-56=0$
⇒ $(a+8)(a-7)=0$
⇒ $a_{1}=-8$ ║ $a_{2}=7$

⇔ For $a=-8$
⇒ the next integer is $(a+1)=-8+1=-7$

⇔ For $a=7$
⇒ the next integer is $(a+1)=(7+1)=8$

∴ So, there are 2 options [ $\boxed{-8}$ and $\boxed{-7}$ ] or [ $\boxed{7}$ and $\boxed{8}$ ]
