33.46/4.78=7

Answer:

90 minutes

Step-by-step explanation:

Given that:

Duration of advert shown per half hour = 3 minutes

3 minutes per 30 minutes = 3 / 30

Number of minutes from 8am to 11pm = 15 hours = (15 * 60) = 900 minutes

3minutes per 30 minutes = x per 900 minutes

3/30 = x / 900

Croas multiply :

30x = 900 * 3

30x = 2700

x = 2700/30

x = 90

Hence, 90 minutes of advert between 8am to 11pm

Answer:

p = 8000 + 2(6000)

20000

Step-by-step explanation:

Given that:

Profit in 1988 = 6000

Profit in 2003 = 8000 more Than double the profit made in 1998

Hence profit in 2003 (p) can be expressed as :

p = 8000 + 2(6000)

Hence profit in 2003

p = 8000 + 12000

p = 20,000

Step-by-step explanation:

when the y intercept goes u, so does the line

Answer:

no

Step-by-step explanation:

because i siad so

Answer:

The options are not shown, so i will answer in a general way.

First, for a line of the form:

y = a*x + b

All the perpendicular lines will have a slope of -(1/a), then we can write a general perpendicular line as:

y = -(1/a)*x + c.

In this problem we have the perpendicular lines:

y=(s/t)*x+10

y = (q/r)*x - 4

Because those lines are perpendicular, we must have that:

(q/r) = -(1/(s/t)) = -(t/s)

q/r = -t/s

and we knew that s, t, q and r are integers (where t and r can not be equal to zero), and because of this relation, where we can see that in the denominator at the right we have the integer s, we can conclude that s can not be zero (we can not divide by zero).

And we know that t and s are both different than zero, then:

-t/s ≠ 0.

This means that:

q/r ≠ 0

And from this, we can conclude that q is different than zero.

Answer:

5,2

Step-by-step explanation:

Answer:

Combine any like terms on each side of the equation: x-terms with x-terms and constants with constants. Arrange the terms in the same order, usually x-term before constants. If all of the terms in the two expressions are identical, then the two expressions are equivalent.

Answer:

the first one is just asking if x increases, does the line go up to down if you look from the graph? The y, or f(X) values will increase as X increases. X intercept means when does the line touched the X axis? From the graph the line touches it at (-3,0)

Answer:

99

Step-by-step explanation:

Answer:

The answer is below

Step-by-step explanation:

Distance between two points [tex]A(x_1,y_1)\ and\ B(x_2,y_2)\ on \ the\ coordinate\ plane[/tex]

[tex]|AB|=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

The perimeter of rectangle = 2(length + breadth)

If the vertices are at (5, 8), (8, 8),(8,10),and (5,10), then:

[tex]length=\sqrt{(8-5)^2+(8-8)^2} =3\\\\breadth=\sqrt{(8-8)^2+(10-8)^2} =2[/tex]

The perimeter of the county would be = 2(length + breadth) = 2(3 + 2) = 10 unit

If the vertices are at A(−2, 5), B(5, 5),C(5,−9),and D(−2,−9), then:

[tex]breadth=|AB|=\sqrt{(5-(-2))^2+(5-5)^2} =7\\\\lenght=|BC|=\sqrt{(5-5)^2+(-9-5)^2} =14[/tex]

The perimeter of the county would be = 2(length + breadth) = 2(7 + 14) = 42 unit

Hello!

We can write an expression to show this scenario. Write this in the equation format y = mx + b:

m = rate of change, or cost per ride

b = initial cost, or cost to enter the fair

y = 2.50x + 4

Solve for the amount of rides possible with $21.50:

21.50 = 2.50x + 4

Subtract 4 from both sides to isolate x:

17.50 = 2.50x

Divide both sides by 2.50:

17.50/2.50 = 7 rides.

Answer:

y = -5x/3 + 18

Step-by-step explanation:

The points can be written as;

(x,f(x))

where f(x) is same as y

So the points we have are;

(6,8) and (9,3)

We start by finding the slope or the line connecting the points

m = y2-y1/x2-x1 = (3-8)/(9-6) = -5/3

So now we have the general form of a linear equation as

y = mx + b

where m is slope and b is y intercept

We already have slope and we want to calculate y-intercept

Simply substitute one of the points

(9,3) in this case

9 for x and 3 for y

we have ;

y = -5x/3 + c

3 = -15 + c

c = 18

So the line equation is;

y = -5x/3 + 18

Answer:

your answer would be D

Step-by-step explanation:

Substitute the x= 3y-1 in place of the x in the second equation

Subtract Like terms

Add 3 to both sides

Divide by 3(the coeffcient of y)

Answer is 5
