Answer:
The subtraction property of equality
Option A is correct
Explanation:
The given equation is:
12 - x = 7x + 32
Subtract 12 from both sides
12 - 12 - x = 7x + 32 - 12
-x = 7x + 20 (Step 1)
From step 1 above, subtract 7x from both sides
-x - 7x = 7x - 7x + 20
-8x = 20 (Step 2)
Since we subtracted 7x from both sides to get step 2, the justification for step 2 is the subtraction property of equality
Answer:
-1/2
Step-by-step explanation:
Slope from equation,
y-3= -1/2(x-2)
y-3=-x/2+1
2y-6=-x+2
x+2y=8
m=-coefficient of x/coefficient of y =-1/2=-1/2
Slope from graph,
(2,3), (4,2) as (x1,y1) , (x2,y2)
m=(y2-y1)/(x2-x1)=(2-3)/(4-2)=-1/2
Answer:
The interval 5-10
Step-by-step explanation:
Because there are 50 kids in total, so you'd go to the 25th number. I know that doesn't make complete sense but trust me.
Hello,
First of all, relax and take a deep breath right before you start.
Alright, so algebraic word problems are tricky sometimes. I am glad I don’t have to do them much. Once you understand more or less what to do, you should be fine!
I would need an example problem if you have one.
If not, then remember that you have to work with what you know, which is what you can start with and what you need to end with.
For instance, a phone company sells phones at $900 each. For a family discount, after 2 phones are bought, each additional phone is $100 off.
Find an expression representing the phone company’s prices.
2*900 + (900x - 100x)
x represents how many additional phones were bought.
If a family bought 6 phones:
2*900 + (900x - 100x)
2 in front and 4 as x gives 6
That expression becomes
2*900 + [900(4) - 100(4)]
= $5000
I hope that helped!
