What is algebraic expression?Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient. An algebraic expression in mathematics is an expression which is made up of variables and constants, along with algebraic operations (addition, subtraction, etc.).These expressions are represented with the help of unknown variables, constants and coefficients. The combination of these three (as terms) is said to be an expression.

What is the value of the expression below when y=3 y=3?
3 y^2 - 4 y + 8 3 y 2 − 4 y + 8
Answer:
When y = 3, we can substitute 3 for y in the expression 3 y^2 - 4 y + 8
3(3^2) - 4(3) + 8
= 3(9) - 12 + 8
= 27 - 12 + 8
= 15
Therefore, the value of the expression 3 y^2 - 4 y + 8 when y = 3 is 15.
Answer:
Basically since y = 3 we just have to remove the 'y' from the equation and replace it with the number 3. (Also pretty sure you wrote the equation twice)
Original Equation:
3 y^2 - 4 y + 8
Modified Equation:
→ 3 (3²) - 4(3) + 8
→ 3 (9) - 12 + 8
→ 27 - 12 + 8
→ 15 (answer)
Equation with 'y' included:
→ y (y²) - 4 (y) + 8
→ y (9) - 12 + 8
→ 27 - 12 + 8
→ 15 (answer)

What is a mortgage?
It is an agreement between you and a lender that allows you to borrow money to purchase or refinance a home and gives the lender the right to take your property if you fail to repay the money you've borrowed. A mortgage is a type of loan that's used to finance the property. A mortgage is a type of loan, but not all loans are mortgages. Mortgages are “secured” loans.
To calculate the monthly payment, we can use the formula:
M = P [i(1 + i)^n] / [(1 + i)^n – 1]
Where M is the monthly payment, P is the loan amount, i is the interest rate, and n is the number of payments (in this case, the number of months in 30 years)
Plugging in the values,
M = 150000 * (0.0929 / 12) / [ (1 + (0.0929 / 12))^(12 * 30) - 1]
This gives a monthly payment of $1238.
To find out how many points he needs to improve his credit score, we can compare this monthly payment to the maximum monthly payment he can afford, which is $14,000.
If $1238 is more than $14,000, he would need to improve his credit score to a point where the monthly payment would be less than $14,000. By looking at the table, we can see that the interest rate for credit score of 620-674 is 7.40%.
Hence, (D) option is the correct answer.

The probability that the track star wins at least one race is 0.8, the probability that she wins the first race but not the second is 0.2, and the probability that she wins the second race but not the first is 0.1
Let A be the event that the track star wins the first race, B be the event that the track star wins the second race.
The probability that the track star wins at least one race is: P(A U B) = P(A) + P(B) - P(A ∩ B)
The probability that the track star wins the first race but not the second race: P(A ∩ B') = P(A) - P(A ∩ B)
The probability that the track star wins the second race but not the first race: P(A' ∩ B) = P(B) - P(A ∩ B)
Given:
P(A) = 0.7
P(B) = 0.6
P(A ∩ B) = 0.5
P(A U B) = 0.7 + 0.6 - 0.5 = 0.8
P(A ∩ B') = 0.7 - 0.5 = 0.2
P(A' ∩ B) = 0.6 - 0.5 = 0.1
So the probability that the track star wins at least one race is 0.8, the probability that she wins the first race but not the second is 0.2, and the probability that she wins the second race but not the first is 0.1.

Two circle of radii 8cm with centre p and q are given the chord AB of circle with centre P and the chord CD of the circle with centre Q are equal if angle PAB=40 then find angle CQD
The angle PAB is given as 40 degrees so we can use the sine rule to calculate the lengths of the chords is CQD = 17.7 degrees.
The sine rule states that the ratio of the length of a side of a triangle to the sine of its opposite angle is equal to the ratio of any other side to the sine of its opposite angle.
Let us denote the length of chord AB by x and the length of chord CD by y.
Therefore x/sin 40 = y/sin (180-40)
=> x/0.766 = y/0.939
=> x = 0.766*0.939 = 0.723
y = 0.939*0.766 = 0.723
Since AB=CD, x=y=0.723.
We can now use the cosine rule to calculate the angle CQD.
The cosine rule states that the square of the length of a side of a triangle is equal to the sum of the squares of the other two sides minus twice the product of the other two sides times the cosine of the included angle.
Therefore CQ^2 = 8^2 + 8^2 - 2(8^2)cosCQD
=> CQ^2 = 64 - 64cosCQD
=> 64 - 64cosCQD = 0.723^2
=> 64 - 64cosCQD = 0.521
=> 64cosCQD = 63.479
=> cosCQD = 63.479/64
=> cosCQD = 0.988
Therefore CQD = cos^-1(0.988)
=> CQD = 17.7 degrees.

Answer:
C
Step-by-step explanation:
This looks like a case of multiplying the number of X's by the respective number below it.
For example: the 1/2 has 3 X's, so we multiple (1/2)(3), making it (3/2) or 1.5
Next is the 1 having 2 X's, so (2)(1) is 2
Continuing that trend we get the following
1.5, 4, 2.5, and 3.
So all of our totals are 1.5, 2, 1.5, 4, 2.5, and 3.
Our last step will be adding all these answers together.
1.5 + 2 = 3.5
+ 1.5 = 6
+ 4 = 10
+ 2.5 = 12.5
and finally +3 = a grand total of 15.5 or 15 1/2
Consider the two equations below. Explain completely the similarities and differences in how you would solve each equation. Be clear and complete.
The first equation, 3^x = 12, is an exponential equation. To solve for x, we would take the logarithm of both sides with base 3:
x = log3(12)
The second equation, x^3 = 12, is a polynomial equation of degree 3. To solve for x, we would take the cube root of both sides:
x = ∛12
How does the equation compare?The similarity between these two equations is that both are equations with one variable and are looking for the value of that variable.
The main difference between these two equations is the type of function they represent. The first equation is an exponential function, represented by 3^x, while the second equation is a polynomial function, represented by x^3.
As a result, the methods used to solve these equations are also different. The first equation is solved by taking the logarithm of both sides and the second equation is solved by taking the cube root of both sides.

Answer: No they are not.
Step-by-step explanation:
1/2x and -5/8x are like terms, if subtracted you get 1 1/8x. But then you are left with an unlike term, 3/4 so your first equation would equal out to 1 1/8x + 3/4
Now for equation 2, you use your distributive property and get 1/8(x)=1/8x
Then you must distribute 1/8(1)=1/8
1/8x + 1/8
So, 1 1/8x + 3/4 ≠ 1/8x + 1/8
