Answer:
Ok so this concept is kind of hard to explain, but basically the two equations are equal because you are adding 9/4 and then subtracting 9/4, so you just end up with 0. The reason you do that is so you can make the (x + 3/2)^2 part, which you wouldn't be able to do without the 9/4/
Answer:
Let's solve your equation step-by-step.
−8−3(w+13)=4(w+11)−7w
Step 1: Simplify both sides of the equation.
−8−3(w+13)=4(w+11)−7w
−8+(−3)(w)+(−3)(13)=(4)(w)+(4)(11)+−7w(Distribute)
−8+−3w+−39=4w+44+−7w
(−3w)+(−8+−39)=(4w+−7w)+(44)(Combine Like Terms)
−3w+−47=−3w+44
−3w−47=−3w+44
Step 2: Add 3w to both sides.
−3w−47+3w=−3w+44+3w
−47=44
Step 3: Add 47 to both sides.
−47+47=44+47
0=91
Plug in values and check for equality.
2(3)+5(1/5)=5
6+5(1/5)=5
6+1=5
7=5
Final answer: No
Answer: y2/10
Step-by-step explanation:
Answer:
f(x) = -3|x| + 2x - 1
f(-5) = -3|-5| + 2*(-5) - 1
= -3*5 + 2*(-5) - 1
= -15 - 10 - 1
= -26
Hope this helps!
