Answer:

-3x^2+2xy-4y^2

Step-by-step explanation:

(x^2+xy-3y^2)-(4x^2-xy+y^2)

x^2-4x^2+xy-(-xy)-3y^2-y^2

-3x^2+xy+xy-4y^2

-3x^2+2xy-4y^2

Is the open sentence 3z=2z+5 true or false when z=5? A. True B. False

inna [77]

Hey there!

If z = 5

we replace "z" with "5"

So, let's test out the problem to see if it is true or false

Problem becomes: $3(5) = 2(5) + 5$

Let's work this out

$3(5) = 15$

Problem becomes: $15 = 2(5) + 5$

$2(5) = 10$

Problem becomes: $15 = 10 + 5$

$10 + 5 = 15$

So, therefore it looks like this statement/ sentence is $True$ !

Write the equation of the line in slope-intercept form using y=mx+b

AnnZ [28]

It looks like it goes through (0,-3) and (1,2), so the gradient is (change in y)/(change in x) ->
(-3-2)/(0-1) = 5
So y=5x+b

Then as we know it passes the y axis at (0,-3) so b= -3

So we have y=5x-3
