The solution 2x² - x - 1 is equivalent to expression y + yz.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.
The operator that performs the arithmetic operation is called the arithmetic operator.
Operators which let do a basic mathematical calculation
+ Addition operation: Adds values on either side of the operator.
For example 12 + 2 = 14
- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.
for example 12 -2 = 10
* Multiplication operation: Multiplies values on either side of the operator
For example 12*2 = 24
Given expression as :
⇒ y + yz
y = x + 1/2 and
z = 2x - 3
Substitute the values of y and z in the expression y + yz,
⇒ x + 1/2 + (x + 1/2)(2x - 3)
⇒ x + 1/2 + x(2x - 3) + 1/2(2x - 3)
⇒ x + 1/2 + 2x² - 3x + x - 3/2
Rearrange the like wise term and apply the arithmetic operations,
⇒ 2x² - 3x + x + x + 1/2 - 3/2
⇒ 2x² - x - 1
Hence, the solution 2x² - x - 1 is equivalent to expression y + yz.

A researcher compared the heights and shoe sizes 50 men selected at random. The equation shown describes a line of best fit for the data,
where x is the shoe size and y is the height, in inches.
y = 1.6x +48
Based on the equation, what is the approximate shoe size for a man having a height of 60 inches?
Answer: 7 1/2
Step-by-step explanation: Convert 7 1/2 to a decimal then multiply it by 1.6 to get 12.00 then add 48 to get 60.

Find the missing length indicated!
(100, 64, x )
Answer:
I don't think it's any of them, is it supposed to add up to 180? If so 100 + 64 obviously equals 164, and 164 -180 equals 16 but there's no 16 as an answer choice

4. Given: a + m = n, n= 4a; Prove: m = 3a
Answer:
Proof below
Step-by-step explanation:
Algebraic Manipulation
It refers to the process of modifying algebraic expressions, often into a simpler form or more easily handled and dealt with.
It also helps us to prove some identities.
We are given the relations:
a + m = n
n = 4a
Substituting the last equation in the first, we have:
a + m = 4a
Subtracting a on both sides of the equation:
m = 4a - a
Simplifying:
m = 3a
Hence proved

f(x) = — 3х2 – 6х +5
maximum and minimum value
9514 1404 393
Answer:
maximum: 8; no minimum
Step-by-step explanation:
A graph can be useful. I find a graphing calculator handy. It shows the maximum of the function is f(-1) = 8. Since the parabola goes to -∞ for large values of x, there is no minimum.
maximum: 8
__
You can also find the maximum by putting the function in vertex form.
-3(x^2 +2x) +5 . . . . factor the leading coefficient from the x terms
-3(x^2 +2x +1) +5 -(-3)(1) . . . . add the square of half the x-coefficient, subtract the equivalent amount
-3(x +1)^2 +8 . . . . . . the vertex form of the expression for f(x)
This form is ...
a(x -h)^2 +k . . . . . with a=-3, h=-1, k=8
so the vertex is (h, k) = (-1, 8) -- the same as shown on the graph. The negative value of 'a' tells you the parabola opens downward, so the vertex is the maximum. The maximum is 8 at x = -1.

help me if ya know this please :D
Answer:
C
Step-by-step explanation:
Key skills needed: Understanding inequalities, Understanding variables
1) The inequality is [tex]120\geq 12x + 29[/tex]
2) This means that 12x + 29 is at most 120, not at least. At least means greater than or equal to. At most means less than or equal to.
3) 29 is the initial amount --> So C is the answer. C says that 29 is the initial amount, and 12 coins are being added every year (k is the number of years). C also says "AT MOST".
Therefore C is the answer
Hope you understood and have a nice day!! :D
