y = -X² -2x +3
What does y equal to?
Answer:
y= -1(x-1)(x+3)
Step-by-step explanation:
The way you can solve this is by factoring and using quadratics
First, you factor out the -1 in the x term
Then, you rewrite the equation into
y= -1(x^2+2x-3)
After that you factor as normal into y= -1(x-1)(x+3)

6v + 38 = -4 or 2(v + 3) = -2
How do I solve this?
The value of v will be equal to -7.
An expression is given i.e., 6v + 38 = - 4
We have to find out the value of v by solving the expression.
What is algebra ?
Algebra is the branch that deals with various symbols and the arithmetic operations such as multiplication , division , etc.
As per the question ;
The given expression is ; 6v + 38 = -4
So ; the value of v after solving the expression will be ;
6v + 38 = - 4
6v = -4 - 38
6v = -42
v = -42/6
v = -7
Thus , the value of v will be equal to -7.

If UV = UX = 34, m∠UWV= 9z–24°, and m∠UWX=z, what is the value of z?
Answer:
z = 3
Step-by-step explanation:
Δ UWV and Δ UWX are similar triangles , thus corresponding angles are congruent , that is
∠ UWV = ∠ UWX , substitute values
9z - 24 = z ( subtract z from both sides )
8z - 24 = 0 ( add 24 to both sides )
8z = 24 ( divide both sides by 8 )
z = 3
Answer:
z=3 is the answer. Hope this helps!

(y-p)^y. (y-p)^y-1. (y-p)^y-2
Answer:
(2p(p - y - 1) + y^2)) / (y - p)^y.
Step-by-step explanation:
p^2 / (y - p)^y - 2p / (y - p)^y + 1 / (y - p)^y-2
The LCD is (y - p)^y
NOTE : (y - p)^y / (y - p)^y-2 = (y - p)^(y - (y - 2)) = (y - p)^2
So we have
(p^2 - 2p + 1( (y - p)^2) / (y - p)^y
= ( p^2 - 2p +y^2 - 2py + p^2) / (y - p)^2
= (2p^2 - 2py - 2p + y^2) / (y - p)^y
= (2p(p - y - 1) + y^2)) / (y - p)^y.

there are 614,952 pepole living in a city round this number ot the nearest thousand
Answer:
615,000
Step-by-step explanation:
When you "round to the nearest _____" regardless of what goes in the blank the steps are nearly always the same:
Identify which place value you are rounding to. The smaller the place value, the more accurate the final result will be.
Look to the next smallest place value, the digit to the right of the place value you're rounding to. For example, if you want to round to the nearest ten you'd look at the ones place.
If the digit in the next smallest place value is less than five (0, 1, 2, 3, or 4), you leave the digit you want to round to as-is. Any digits after that number (including the next smallest place value you just looked at) become zeros, or drop-off if they're located after the decimal point. This is called rounding down.
If the next smallest place value is greater than or equal to five (5, 6, 7, 8, or 9), you increase the value of the digit you're rounding to by one (+1). Just like before, any remaining digits before the decimal point become zeros, and any that are after the decimal point are dropped. This is called rounding up.
Answer:
615,000
Step-by-step explanation:
614,952
Locate the thousands place:
614,952
Check next door:
614,952
If the number is greater than or equal to 5, then we round up. If it is less than or equal to 4, we round down.
9 is greater than 5. We would round up.
614,952 ≈ 615,000

Logs are stored in apile of 20 rows,with each row having one fewer log than the one below it. If there is 48 logs on the bottom row how many logs are in the pile?
Answer:
754 logs
Step-by-step explanation:
If you are starting at 48 logs on the bottom row subtracting one log for each row you go up, then you should have 28 logs in the top row.
This is because 48-20=28
now you need to find the factorial of 48 starting at 28.
Factorial is like 1+2+3+4+5=15. So it is basically just adding every single whole number that are in between 2 whole numbers.
So for this equation you would need to do: 28+29+30+31+32+33+34+35+36+37+38+39+40+41+42+43+44+45+46+47+48= 754.

Answer:
41/100
Step-by-step explanation:
All you need to do to turn a decimal into a fraction is move the decimal over however many times to get through the number and put it over "1 (+ a zero for every point you move over)"
For example if that didn't make sense:
0.645 -> 645/1000
0.4 -> 4/10
0.66 -> 66/100
