Answer:

y-intercept=1000

slope=400

y=400x+1,000

Answer:

Second table

Step-by-step explanation:

y  = 8x + 3                         (x, y)

      8(2) + 3 =   19             (2, 3)

      8(4) + 3  =  35             (4, 35)

      8(6) + 3  =  51              (6, 51)

      8(8) + 3  =   67             (8, 67)

      8(10) + 3 = 83              (10, 83)

Answer: y=5x + 5

Step-by-step explanation:

The standard form of an equation for a straight line is y=mx+b, where m is the slope and b is the y-intercept (the value of y when x = 0).

The slope is given as 5, so we have y = 5x + b.

To find b, enter the given point (1,10) and solve for b:

   y = 5x + b

   10 = 5(1) + b

b = 5

The equation of a line with slope 5 and point (1,10) is y=5x + 5.

Check this with a DESMOS graph (attached).

Answer: x intercept= (-10,0) y intercept = (0,-40)

Just look at where the line hits the x axis for the x intercept, then those coordinates are your x intercept. Then for the y intercept, look at where the line meets the y axis and then that point's coordinates are your y intercept.

Hope this helps!

Answer:

x =38/5

Step-by-step explanation:

(x – 2) = –14(x – 8)

Distribute

x-2 = -14x+112

Add 14x to each side

x-2+14x = -14x+14 +112

15x-2 = 112

Ad 2 to each side

15x-2+2 = 112+2

15x= 114

Divide each side by 15

15x/15 = 114/15

x=114/15

Divide top and bottom by 3

x =38/5

Step-by-step explanation:

so, there are 14 people with 1 ticket each, and I have 2 tickets.

that means there are 16 tickets (14+2) in the raffle.

each ticket has therefore a winning probability of 1/16.

I have 2 tickets, so my winning probabilty is therefore

1/16 + 1/16 = 2/16 = 1/8

5x I think I don't know is it right look in calculator

The value of (3x + 2) when (7 + x = 5) is -4.

A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

We have the following equation as -

x + 7 = 5

We can write -

x + 7 = 5

x = 5 - 7

x = - 2

Now, we have to find -

3x + 2

3(-2) + 2

- 6 + 2

- 4

Therefore, the value of (3x + 2) when (7 + x = 5) is -4.

Answer:

53/36

Step-by-step explanation:

56/36 is already in it's simplest form

Answer:

1 17/36

Step-by-step explanation:

Turn each fraction into their LCD (least common denominator)

5/9 turns into 20/36

11/12 turns into 33/36

add 20 + 33 = 53

Keep denominator  53/36

53/36 simplified as mixed number =  1 17/36

Step-by-step explanation:

Answer:

x = 15

y = 9

Step-by-step explanation:

( 4y + 9 ) and 15y are co - interior angles.

Sum of co - interior angles is 180,

4y + 9 + 15y = 180

4y + 15y = 180 - 9

19y = 171

y = 171 / 19

y = 9

( 6x - 15 ) and ( 4x + 15 ) are alternate exterior angles.

Alternate exterior angles are equal,

6x - 15 = 4x + 15

6x - 4x = 15 + 15

2x = 30

x = 30 / 2

x = 15
