Mathematics
1 answer:
Advocard [28]3 years ago
3 0

Answer:

4.5 OR 4 1/2

Step-by-step explanation:

Equation: (2nd y - 1st y) / (2nd x - 1st x)

Plug it in (assuming (0,-5) is point 1) :

(4--5)/(2-0)

(4+5)/(2)

9/2

4 1/2

4.5

Will give BRAINLEST :)
DiKsa [7]

Answer:

A

Step-by-step explanation:

This explanation mostly depends on what you're learning right now. The first way would be to convert this matrix to a system of equations like this.

g + t + k = 90

g + 2t - k = 55

-g - t + 3k = 30

Then you solve using normal methods of substitution or elimination. It seems to me that elimination is the quickest method.

g + t + k = 90

-g - t + 3k = 30

____________

0 + 0 + 4k = 120

4k = 120

k = 30

No you can plug this into the first two equations

g + t + (30) = 90

g + t = 60

and

g + 2t - (30) = 55

g + 2t = 85

now use elimination again by multiplying the first equation by -1

g + 2t = 85

-g - t = -60

_________

0 + t = 25

t = 25

Now plug those both back into one of the equations. I'll just do the first one.

g + (25) + (30) = 90

g = 35

Therefore, we know that Ted spent the least amount of time on the computer.

The second method is using matrix reduction and getting the matrix in the row echelon form, therefore solving using the gauss jordan method. If you would like me to go through this instead, please leave a comment.

Find the value of x.<br><br> Brainlest for anyone who answers and explains it!
sergejj [24]

Answer:

x=-2

Step-by-step explanation:

Since it is an equilateral triangle (note the little lines across the legs of corner 2) the other angle must be 69° as well.

That leaves 180-69-69 = 42 for ∠2.

So x + 44 = 42 => x = 42-44 = -2.

3) show that the two lines with the given slopes are parallel, perpendicular neither. My₁ = 3/4 M₂ = 12/16 . solve it by showing
Jet001 [13]

Parallel lines have equal slope so

  • M1-M2=0

Lets check

  • M1=3/4
  • M2=12/16=3/4

Now

  • M1-M2
  • 3/4-3/4
  • 0

Lines are parallel
