Add 2x to both sides,
3x+9=18
Subtract 9 from both sides. 3x=9
Divide both sides by 3.
x=3
Answer:
y = -7/4x - 11
Step-by-step explanation:
formula is y = mx + b
m is the slope
b is the y intercept
y = -7/4x -11
which is the first one
Answer:
The answer is 27
Step-by-step explanation:
I worked it out using a calculator
-4k²(k+6)(k-1). The expression 
can be factored by factor completely to the expression -4k²(k+6)(k-1).
To factor the polynomial by factor completely, we must to use the pattern as follows:
1. Greatest Common Factor
factored into 
2. Factor the trinomial
Answer:
1/2x - 8
Step-by-step explanation:
Let
x = number of pledges she collected last year
The number of pledges that Melissa collected for this year's charity walk is 8 less than half the number of pledges she collected last year.
Number of pledges she collected this year = 1/2x - 8
The expression which represents the number of pledges she collected this year = 1/2x - 8
