How do I graph x-4y=4 and 3x+y=-1​

Mathematics
1 answer:
ololo11 [35]2 years ago
8 0

Answer:

Draw all these points and draw a straight line through all of them.

Step-by-step explanation:

y = mx + b

x - 4y = 4

-x          -x

-4y = -x + 4

/-4      /-4

y = \frac{1}{4}x -1

(0,-1),(4,0),(-8,-3),(-4,-2),(8,1) - The first graph attached

3x+y=-1​

y = -3x - 1

(0,-1),(-1,2),(-3,8),(2,-7),(3,-10) - The second/last graph attached.

Hope this helps!

Determine if the following series converges or diverges. Show steps!
MAXImum [283]
Converges by p series test
top section is almost constant, can never be larger than 3
so, compare degrees of their exponents, in this case it’s at a maximum of 3/1000n^2. the same as saying (3/1000)*summation of p series.
converges absolutely.

Aline with a slope of contains the point (3.4). The point ( - 2 ) is also on the
Maru [420]

Answer:

Not Sure Without Slope

Step-by-step explanation:

you could use the formula y-y1=m(x-x1)(point slope form) where m is the slope, y1 is the first y point and x1 is the first x point.

For example if a line has slope 3 and passes through the points (5, 6), then the formula you would solve is y-6=3(x-5) to find the equation of the line in slope-intercept form and you should know what to do with everything else.

Find the slope of the line that passes through the coordinates (3,-6) and (-9,2)
JulsSmile [24]

9514 1404 393

Answer:

  -2/3

Step-by-step explanation:

The slope formula is useful for this.

  m = (y2 -y1)/(x2 -x1)

  m = (2 -(-6))/(-9 -3) = 8/-12

  m = -2/3

The slope of the line is -2/3.

__

The graph shows the two points and a line with a slope of -2/3.

Determine whether the quantitative variable is discrete or continuous. Number of students in a class Is the variable discrete or
olga nikolaevna [1]

Answer:

D) The variable is discrete because it is countable.      

Step-by-step explanation:

Both discrete and continuous falls under the numeric category.

Discrete variables are the variable that are countable and cannot be expressed in decimal form.

Example: Tosses of a coin, Number of rooms in an house.

Continuous variables on the other hand cannot be counted, they are countable and can be expressed in the form of decimals. Its value can be expressed in the form of interval.

Example: Time, Length.

Now, number of students in a class is a discrete variable since students are countable and they cannot be expressed in decimal form.

So the correct option is D) The variable is discrete because it is countable.
