Answer:
y = 1/2x - 11
Step-by-step explanation:
Step one convert to y = mx+b form
6x + 3y =15
Isolate Y
3y = -6x + 15
Divde the 3 among the other numbers
y = -2x + 5
That is the equation
perpindiculr to that is y = 1/2x + 5 but solve for the points and plug in
the points are (12,-5)
So -5 = 1/2 (12) +b
-5 = 6 + b
Solve for B
-5 - 6 = b
b = -11
FINAL EQUATION
y = 1/2x - 11
3.5(2.25+x)=14
Step 1: Simplify both sides of the equation.
3.5(2.25+x)=14
(3.5)(2.25)+(3.5)(x)=14(Distribute)
7.875+3.5x=14
3.5x+7.875=14
Step 2: Subtract 7.875 from both sides.
3.5x+7.875−7.875=14−7.875
3.5x=6.125
Step 3: Divide both sides by 3.5.
3.5x/3.5=6.125/3.5
x=1.75
You could use something like I have 17 people in my class. I want to give them each 6 pencils. How many pencils do I need. I think this is what your were asking for
D none of the above is the answer
