(4y-y)x(9+4x+3y)
Subtract the terms 3yx(9+4x+3y).
Add the terms 3yx(4x+3y+9).
Apply the distributive property
3yx4x+3yx3y+3yx9.
Multiply the terms 12xy+3yx3y+3yx9.
Multiply the terms 12xy+9ysq+3yx9.
Solution = 12xy+9ysq+27y..............
(Note I put sq because my phone don’t allow 2 on a y)

Step-by-step explanation:

(4y-y)(9+4x+3y)

36y+16xy+12y^2-9y-4xy-3y^2

collect like terms

36y-9y+16xy-4xy+12y^2-3y^2

=27y +12xy+9y^2

What is 25+120-10x=10x-35=
Alexandra [31]
145-10x=10x-35

Add 35 to both sides.

175-10x=10x

Add 10x to both sides.

175=20x

Divide both sides by 20

8.75=x

If 2a+4b=5 and a is equal to three times b, what is 3a?
IrinaK [193]

Answer:

3a=4.5

Step-by-step explanation:

it says that "a is equal to 3 times b", which translates to a=3b

We can substitute a as 3b in 2a+4b=5

2(3b)+4b=5

multiply

6b+4b=5

add

10b=5

divide by 10

b=1/2

since it's given that a=3b, we can multiply 1/2 by 3

a=3/2

3a is 3 times a, so we can mutiply 3(3/2)=9/2=4.5

Hope this helps!

For each graph below, state wether it represents a function.
Paul [167]

Answers:

Row 1: No, No, No

Row 2: Yes, Yes, Yes

===============================

Explanation:

Use the vertical line test. If it is at all possible to draw a single vertical line through more than one point on the relation curve, then the relation is not a function. This is because a function is only possible when any x input leads to exactly one y output.

So that's why graphs 1,2,3 are not functions, while graphs 4,5,6 are functions.
