Line A has an x-intercept of -4 and a y-intercept of 8. What is its slope?

Mathematics
1 answer:
Tanzania [10]3 years ago
8 0

Answer:

Step-by-step explanation:

We can use the intercept form of the equation of a line, then solve for y.

<u>Intercept form</u>

  x/(x-intercept) +y/(y-intercept) = 1

  x/-4 +y/8 = 1

__

Solving for y, we have ...

  -2x +y = 8 . . . . multiply by 8

  y = 2x +8 . . . .  add 2x

The coefficient of x is 2, so the slope is 2.

__

The graph shows you the rise is 8 for a run of 4, so ...

  slope = rise/run = 8/4

  slope = 2

2x+2y=-2<br> 3x-2y=12<br><br> What is this please
nydimaria [60]

Answer:

x=2, y=-3

Step-by-step explanation:

This type of problems is called a system of equations, or simultaneous equations.

When solving simultaneous equations, you need to first make sure you have two unknown terms of the same number but different signs - this is so one unknown cancels out because we can only solve when there's one unknown. We already have this ('2y' and '-2y'). Now we just add the 'x's, the 'y's and the numbers:

2x+2y=-2

3x-2y=12

(2x+3x)+(2y-2y)=(-2+12)

5x=10

x=2

Now that we know the value of x, use it to find y:

2x+2y=-2

2(2)+2y=-2

4+2y=-2

2y=-6

y=-3

Dont know how to solve for x can someone help me

  57 + x + x + 130 = 167
  57 + 2x + 130 = 167
    187 + 2x = 167
  - 187          - 187
---------------------------
    2x = -20
  ------  -------
     2       2

x = -10

Can you help Jorge organize the results into a two-way frequency table? Please answer this ASAP
Juliette [100K]

Answer:

The table is attached!

Step-by-step explanation:

  • 6 students play both musical instrument and a sport
  • 3 students play neither a musical instrument nor a sport
  • 14 students in total play a sport

Given: There are 24 students in the class

The number of students that does not play a sport is 24 - 14 = 10

The number of students that does not play a musical instrument but play a sport = 14 - 6 = 8

The frequency table thus is attached below:
