Step-by-step explanation:
2y+9= 4
2y=-5
y=-5/2
y= -2and 1/2
Answer:
6, just divide
Step-by-step explanation:
Hope this helps!!!! :))
We have the equation:

So then we need to distribute -7p to the parentheses:

Then we need to set the equation equal to 0, so we must subtract 21 on both sides:

Then we need to factor this. So we end up with:

This is as much as this can be factored, so <u>we cannot go any further</u>.
Answer:
Simplest form = 4<em>z </em>+ 21
Case 1: True, Case II: false and Case III: true
Step-by-step explanation:
18<em>z </em>- 7( -3 + 2z)
= 18<em>z</em> + 21 - 14z
= 18<em>z</em> -14z + 21
= 4<em>z </em>+ 21
So, in the above expression we have two terms. First term is 4z and second term is 21.
So the first case is true. As the expression has two terms.
The coefficient of <em>z </em>is a number which is multiplied by <em>z</em>. Therefore, Second case is false as the coefficient of <em>z</em> is 4.
The constant is a number which is not multiplied by any variable. Therefore, third case is true as the constant number in above expression is 21.
Hey! the answer is 90000.
