Answer:

-5

Step-by-step explanation:

Find the y-intercept by plugging in x = 0:

  y = 3x^2 - 12x - 5

  y = 3(0^2) - 12(0) - 5

  y = 0 - 0 - 5

  y = -5

Answer:

rs 28500

Step-by-step explanation:

If she saves rs3420 and spends 88% we need to convert 88% to a decimal first.

88% = 88/100 = .88

Let m equal her monthly income.

m - .88m = 3420

.12m = 3420

.12m/.12  = 3420/.12

m =  3420/.12

m = 28500

He monthly income is rs28500.

Answer:

lifeguarding: 6 hours

tutoring: 10 hours

Step-by-step explanation:

First, to be able to tell apart the two jobs, use the variable x and y for them. use x for lifeguarding and y for tutoring. Since you have the pay per hour, you can create an expression for his pay:

11x + 22y

Then, write a system of equations to be able to find both variables.

If Parker worked a total of 16 hours, then you know that the combined amount of worked hours will be:

x + y = 16

If Parker earned a total of $242, then you know that his combined pay will be:

11x + 22y = $242

Now, you solve the system of equations (IMAGE.A):

First, solve for x:

11x + 22y = 242

11x = 242 – 22y

x = 22 – 2y

Now, plug in the x-value in the other equation:

x + y = 16

22 – 2y + y = 16

22 – y = 16

–y = –6

y = 6

This means that he has worked 6 tutoring hours.

Now, plug in the y-value to find the x-value:

11x + 22y = 242

11x + 22(6) = 242

11x + 132 = 242

11x = 110

x = 10

this means that he has worked 10 lifeguarding hours.

Answer:

10 hours lifeguarding, 6 hours tutoring

Answer:

A regular polygon has these characteristics:

A polygon can not have one or two sides because that would be a line. It must have more than three sides, or else it is not a polygon.

A polygon is always a closed shape - it can not be an open shape or else it would not be a polygon, it would be considered an outline.

Answer:

13 seconds

Step-by-step explanation:

Since distance is directly proportional to time,

distance = time * a constant

Lets make A the constant

So, 54 = 9A

A = 6

Now, since distance = 78,

78 = time * A

From above, we can see that A = 6, so

78 = time *6

time = 13

Answer:

13

Step-by-step explanation:

54/9=6, 6 is the rate at which the car travels. 78/6 is 13 so that is how far the car traveled

Answer:

m = 1

Step-by-step explanation:

Slope is defined by the change in y over the change in x, [tex]\frac{\Delta y}{\Delta x}[/tex]. A trick here is to find where 2 points where the slope intersects a corner of the square grids. For example, here, it can be (0,1) and (1,0). Then, you count how many squares you needed to go up or down by and divide by the number of square you needed to move right or left by. If you move up or right, the value will be positive and vice versa for down and left. Which direction you go will depend on which point you start on. Here, we can see between (0,1) and (1,0), we need to move up 1 and right 1. Meaning 1/1 is the slope or m = 1. If this doesn't make sense, just ignore it but it may come in handy when you move to more complex problems where the slope is a fraction or something.

Answer:

b= -1

m=1

Step-by-step explanation:

the equation for a linear graph is y=mx+b

your y intercept would be -1 because thats where the line crosses on the y axis. The slope which would be 1 is because when you are on the point (0,-1) you go up one and one to the right and get (1,0)

therefore the equation would be

y=1x-1 or y=x-1

Answer:

- 1

Step-by-step explanation:

The product of the slopes of lines perpendicular to each other is - 1

Given y = 4x - 5 with slope 4

y = - [tex]\frac{1}{4}[/tex] x - 5 with slope - [tex]\frac{1}{4}[/tex] then

4 × - [tex]\frac{1}{4}[/tex] = - 1 proving the lines are perpendicular

Answer:

Nancy gastó 8,58 dólares.

Step-by-step explanation:

Para calcular cuánto dinero gastó Nancy, debemos hallar la relación entre Nancy y María, tal como sigue:

[tex] M = 3N [/tex]    (1)

En donde M es por María y N por Nancy

En la relación de la equación (1) tenemos que el dinero que gastó María es 3 veces lo que gastó Nancy, tal como dice el enunciado.

Entonces, podemos hallar ahora cuánto gastó Nancy:

[tex] N = \frac{M}{3} = \frac{25,75}{3} = 8,58 [/tex]

Por lo tanto, Nancy gastó 8,58 dólares.
