Answer:
r - 24
Step-by-step explanation:
[X · Y - Z] = (r + 2)(2r - 9)] - (r^2 + 17r + 30)
= (2r^2 + 4r - 9r - 18 ) - r^2 - 17r - 30
= 2r^2 - 5r - 18 - r^2 - 17r - 30
= r^2 - 22r - 48
= (r +2)(r - 24)
so
[X · Y - Z] / X
= [(r +2)(r - 24)] / (r + 2)
= r - 24
How many times does 5 go into 29? It can go into it 5 times which equals 25. Now what's 29 - 25? 4 is the answer then you see how many times can 5 go into 4, well it can't so then you bring the number 0 to make it 40. Now how many times can 5 go into 40? It can go into 40 eight times since 8x5=40 so the answer is 58
Answer:
(-1,-2)
Step-by-step explanation:
There is a solution where the two expressions intersect. We can plug in what we know in the first equation in the second.
x= -1
y=3x+1
y= 3(-1)+1
y= -3+1
y= -2
Plugging y value in the equation to find x:
-2=3x+1
-3=3x
x= -1
Therefore, the point is (-1,-2)

X>7/6
Combine like terms
Subtract 2.75x from both sides
Combine like terms
Divide -1.5 from both sides
