Answer:

y=2x+2

Step-by-step explanation:

step 1

Find the slope

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

we have

A(-4,-6)\ B(2,6)

Substitute the values

m=\frac{6+6}{2+4}

m=\frac{12}{6}=2

step 2

we know that

The equation of the line into slope intercept form is equal to

y=mx+b

we have

m=2

B(2,6)

substitute and solve for b

y=mx+b ------> 6=(2*2)+b

6=4+b

b=2

The equation of the line is equal to

y=2x+2

I need help with this ASAP and can you explain so i can understand?!

Answer:

Adult tickets sold =  225

Student Tickets sold =  375

Step-by-step explanation:

Let:

Adult tickets sold = x

Student Tickets sold = y

Total tickets sold = 600

So, we can write: x+y = 600

Total money collected = 3037.50

Cost of 1 Adult ticket = $6.00

Cost of one Student ticket = $4.50

So, we can write: 6x+4.5y=3037.50

Now, we get a system of equations, that if solved we can find values of x and y

Let:

x+y = 600--eq(1)\\6x+4.5y=3037.50--eq(2)

We can solve using substitution method.

Finding value of x from eq(1) and putting it in eq(2)

We\:have\\x+y=600\\x=600-y

Put in eq(2)

6x+4.5y=3037.50\\6(600-y)+4.5y=3037.50\\3600-6y+4.5y=3037.50\\-1.5y=3037.50-3600\\-1.5y=-562.5\\y=\frac{-562.5}{-1.5}\\y=375

So, we get value of y = 375

Now put value of y in eq(1) to find value of x

x+y=600\\Put\:y=375\\x+375=600\\x=600-375\\x=225

So, we get value of x = 225

The Tickets sold will be:

Adult tickets sold = x = 225

Student Tickets sold = y = 375

1) Which of the following shows the correct steps to find the value of 27 1/3?
sesenic [268]
First of all, we need to know: 3^3 = 3 x 3 x 3 = 9 x 3 = 27

So:

(27)^{\frac{1}{3}} = (3^3)^{\frac{1}{3}} = (3)^{3\times \frac{1}{3}} = 3^{1} = 3

So, your answer is D.
