Write the slope-intercept form of the equation of each line.0=-8x-6y
Kay [80]

Nana, this is the solution:

The slope intercept form is:

y = mx + b

Our equation is:

0 = -8x -6y

6y = -8x + 0

Dividing by 6 at both sides:

6y/6 = -8/6x

y = -4/3x

This is the solution.

mihalych1998 [28]

Answer:

At the restaurant you only have $30 to spend on dinner.

=> 8% sales tax is applied in your bill.

=> And need to leave a 20% tip.

Now, let’s find out how much will be the most expensive item you can order

Let us solve for the 8% tax first

=> 30 dollars * 8%

=> 30 dollars *.08 = 2.4 dollars

Then let’s solve the 20% tip

=> 30 dollars * .20 = 6 dollars

Solve

=> 2.4 + 6.00 = 8.4 dollars

=> 30 dollars – 8.4 dollars = 21.6 dollars

Thus, you can only spend around 22 dollars to be able not to exceed at your 30 dollars budget.

D(-3,5)
asambeis [7]

Answer:

4\sqrt{37} units is the perimeter of square ABCD.

Step-by-step explanation:

Coordinates of square ABCD:

A = (3,4), B = (2,-2), C = (-4-1) , D = (-3,5)

Distance formula: (x_1,y_1),(x_2,y_2)

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Distance of AB: A = (3,4), B = (2,-2)

AB=\sqrt{(2-3)^2+(-2-4)^2}

AB=\sqrt{(-1)^2+(-6)^2}=\sqrt{37} units

Given that the ABCD is square, then:

AB = BC = CD = DA

Perimeter of the square ABC = AB +BC + CD + DA

AB+ AB+ AB+ AB= 4AB=4\sqrt{37} units

4\sqrt{37} units is the perimeter of square ABCD.
