Elena L [17]3 years ago

Answer:

x+y+z-2t

Step-by-step explanation:

There are t students taking all three and the rest take only 1 language.

The number taking only Oriya is x-t .

The number taking only Dakhini is y-t .

The number taking only Dutch is z-t .

So the number of students altogether is  

x-t  +  y-t  +  z-t  +  t   = x+y+z-2t.

Hope this helps! :D

X+y+z=t
simple..
there are no other numbers that we have to follow like (1/2x or 3/4y) so it is just all together=t. the x, y, z will equal t because t is the total number of students taking three languages. And that number should be equivalent to x,y,z combined.

otherwise?? i d k<span />

Write the equation of the line that passes through the points (-9, -3) and (-7,7).
tiny-mole [99]

Answer:

y=5x+42

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(7-(-3))/(-7-(-9))

m=(7+3)/(-7+9)

m=10/2

m=5

y-y1=m(x-x1)

y-(-3)=5(x-(-9))

y+3=5(x+9)

y=5x+45-3

y=5x+42

Someone help me please☹️
Levart [38]

Answer:

my best advice: look at the y-intercepts!

Step-by-step explanation:

when the equations are set out like this, the last number (in this case "+4" and "-2"), represents where they cross the y axis. this gives you a great place to start.

if you plot (0, 4) for the first equation, you can then move right one square and down one square to get the next point in the equation.

the next one starts with (0, -2) and goes right one square and up two
