Hey! :)
So when we write something in slope intercept form, all we're doing is solving for y. So let's do that with this equation!
-2x + y = 9
add 2x to both sides
y = 2x + 9
So C is your answer.
Please let me know if you need anything further explained!
Answer:
Distributive property is used to expand expressions by multiplying the factor to every term in the group and combining similar terms if there are any. Hope this helps!
Step-by-step explanation:
An example is...
3(x+4) + 3(y-8)
This is the same thing as...
3x + 12 + 3y -8
Answer:
-3.5
Step-by-step explanation:
2x+21/2=x+7
2x + 10.5 = x + 7
-x -x
x + 10.5 = 7
-10.5 -10.5
x = -3.5
Answer:
113.1in²

If the digits are a, b and c, the number n is 100a+10b+c
Here are the equations:
a number equals fifteen times the sum of its digits:
100a+10b+c = 15(a+b+c)
if its digits are reversed, the resulting number exceeds n by 396:
100a+10b+c+396 = 100c+10b+a
the one’s digit is one larger than the sum of the other two:
a+b+1 = c
Solving it gives you a=1, b=3, c=5, the number is 135.
