Answer:
- 7
Step-by-step explanation:
d = a₂ - a₁ = a₃ - a₂ = - 2 - 5 = - 9 - (- 2) = - 7
Answer:
y = 4
Step-by-step explanation:
-1y = -4
Divide both sides by -1 to get y by itself.
-1/-1 = -4/-1
y = 4
It's positive because there are two negatives, which mean they cancel out.
When u have a polynomial with more then one variable....and this one has more then 1 variable, the degree is the sum of the exponents in each term....and the degree is the largest sum
-14abc...this term has a degree of 3
2b^2....this term has a degree of 2
so this polynomial has a degree of 3 <==
Answer:Simplifying
3(2w + -7) = 3
Reorder the terms:
3(-7 + 2w) = 3
(-7 * 3 + 2w * 3) = 3
(-21 + 6w) = 3
Solving
-21 + 6w = 3
Solving for variable 'w'.
Move all terms containing w to the left, all other terms to the right.
Add '21' to each side of the equation.
-21 + 21 + 6w = 3 + 21
Combine like terms: -21 + 21 = 0
0 + 6w = 3 + 21
6w = 3 + 21
Combine like terms: 3 + 21 = 24
6w = 24
Divide each side by '6'.
w = 4
Simplifying
w = 4
Step-by-step explanation:
Keep your grades up like no less than an A or B average and if they cant afford to pay it all try different sports and get a scholarship, but it will still require a lot of work and stay out of trouble to that's important into getting into any good college.
