Answer:
thank you for the points :D
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
9*2+6*y-(6)=0
<span>Step by step solution :
</span><span>Step 1 :</span>Pulling out like terms :
<span> 1.1 </span> Pull out like factors :
12 + 6y = 6 • (y + 2)
<span>Equation at the end of step 1 :</span><span>Step 2 :</span>Equations which are never true :
<span> 2.1 </span> Solve : 6 = 0
<span>This equation has no solution.
</span>A a non-zero constant never equals zero.
Solving a Single Variable Equation :
<span> 2.2 </span> Solve : y+2 = 0<span>
</span>Subtract 2 from both sides of the equation :<span>
</span> y = -2
One solution was found : y = -2

It looks like the practice ones are all that matter so I'm only going to answer those. If you need the others answered let me know.
1. 5k-9=-3k+7
Add 9 to both sides: 5k-9+9=-3k+7+9
5k=-3k+16
Add 3k to both sides: 5k+3k=-3k+16+3k
(You are adding 3 and 9 instead of subtracting them because in the equation, they are negative numbers and you have to do the opposite operation to get rid of them.)
8k=16
Divide both sides by 8: 8k/8=16/8
k=2
2. 2(w-3)+5=3w-2
Use the distributive property: 2*w-2*3+5=3w-2
2w-6+5=3w-2
Combine like terms: 2w-1=3w-2
Add 1 to both sides: 2w-1+1=3w-2+1
2w=3w-1
Subtract 3w from both sides: 2w-3w=3w-1-3w
-w=-1
Divide both sides by -1: -w/-1=-1/-1
w=1
3. 8t+9=7t+6
Subtract 9 from both sides: 8t+9-9=7t+6-9
8t=7t-3
Subtract 7t from both sides: 8t-7t=7t-3-7t
t=-3
Answer:
C. Plants will absorb the most energy between May and July
Step-by-step explanation:
the amount of light does not effect the birds only the weather does, the plants use the light to photosynthesis so they will make more energy
