4.)In the expression "-5x- 4x^2 +9", what is the coefficient of "X"?
A.)-4
B.)-5
C.)5
D.)9
Remember that a coefficient is a numerical or constant quantity placed before and multiplying the variable in an algebraic expression in Math. The coefficient of "x" would be -5.
Another coefficient is 4, but there is only -4, which isn't in the equation.
the answer is -5 dubass
uuummm., Ion get it ?,
-5, also the kid above me is 6ay fs.

(5x^2 + x - 3) - (-2x^3 + 4)
(5x^2 + x - 3) - (-2x^3 + 4)
= 5x^2 + x - 3 + 2x^3 - 4 (distributing the negative sign)
= 2x^3 + 5x^2 + x - 7

supposed you earned 6t + 2 dollars on monday and 9t - 6 dollars on tuesday. what were you total earnings? simplyfy your answer
If you earned 6t + 2 dollars on Monday and 9t - 6 dollars on Tuesday, then your total earnings would be (6t + 2) + (9t - 6) dollars.
Combining like terms, we get 15t - 4 dollars.
Therefore, your total earnings were 15t - 4 dollars.

f^2 x f^4
When multiplying variables with exponents, we add the exponents.
So, f^2 x f^4 can be simplified as:
f^2 x f^4 = f^(2+4) = f^6
Therefore, f^2 x f^4 is equal to f^6.

64^10/64^5
When dividing exponential expressions with the same base, we subtract the exponents.
So,
64^10 / 64^5 = 64^(10-5) = 64^5
Therefore, 64^10 / 64^5 is equal to 1,073,741,824 (64 raised to the 5th power).
2^2 x 2^22
When multiplying exponential expressions with the same base, we add the exponents.
So,
2^2 x 2^22 = 2^(2+22) = 2^24
Therefore, 2^2 x 2^22 is equal to 16,777,216 (2 raised to the 24th power).
3^4/3^4
Any non-zero number raised to the power of zero is equal to 1. Therefore,
3^4/3^4 = 1
3^3/3^6
When dividing exponential expressions with the same base, we subtract the exponents.
So,
3^3/3^6 = 3^(3-6) = 3^(-3)
Recall that a negative exponent indicates the reciprocal, so
3^(-3) = 1/3^3 = 1/27
Therefore, 3^3/3^6 is equal to 1/27.
(9 x 10^6) x (7 x 10^5)
When multiplying numbers in scientific notation, we multiply the coefficients and add the exponents.
So,
(9 x 10^6) x (7 x 10^5) = (9 x 7) x 10^(6+5) = 63 x 10^11
Therefore, (9 x 10^6) x (7 x 10^5) is equal to 63 x 10^11.
(1.1 x 10^-5) x (3 x 10^-2)
When multiplying numbers in scientific notation, we multiply the coefficients and add the exponents.
So,
(1.1 x 10^-5) x (3 x 10^-2) = (1.1 x 3) x 10^(-5-2) = 3.3 x 10^-7
Therefore, (1.1 x 10^-5) x (3 x 10^-2) is equal to 3.3 x 10^-7.
(9 x 10^6) x (7 x 10^5)
a) 1.6 x 10^31
b) 1.6 x 10^12
c) 6.3 x 10^31
d) 6.3 x 10^12
The product of (9 x 10^6) and (7 x 10^5) is:
(9 x 10^6) x (7 x 10^5) = (9 x 7) x 10^(6 + 5) = 63 x 10^11
This value can also be expressed in scientific notation as 6.3 x 10^12. Therefore, the answer is option:
d) 6.3 x 10^12
7t^4 x 7t^4
When multiplying exponential expressions with the same base, we add the exponents.
So,
7t^4 x 7t^4 = (7 x 7) x t^(4+4) = 49t^8
Therefore, 7t^4 x 7t^4 is equal to 49t^8.
-6(4x + 9)
When multiplying a number by a set of parentheses, we use the distributive property to simplify.
So,
-6(4x + 9) = (-6 x 4x) + (-6 x 9) = -24x - 54
Therefore, -6(4x + 9) simplifies to -24x - 54.
5k^2(-6k^2 - 2k + 6)
When multiplying a set of parentheses by another factor, we use the distributive property to simplify.
So,
5k^2(-6k^2 - 2k + 6) = -30k^4 - 10k^3 + 30k^2
Therefore, 5k^2(-6k^2 - 2k + 6) is equal to -30k^4 - 10k^3 + 30k^2.
(-4x) x 9x^2
answer these 2 questions bot:
question 1: (-4x) x 9x^2
question 2: (6y^2 - 4y) + (7y^2 - 7y)
Answer 1:
When multiplying variables with exponents and coefficients, we multiply their coefficients and add their exponents.
So,
(-4x) x 9x^2 = (-36x^3)
Therefore, (-4x) x 9x^2 is equal to -36x^3.
Answer 2:
When adding or subtracting algebraic expressions, we combine like terms.
So,
(6y^2 - 4y) + (7y^2 - 7y) = 6y^2 + 7y^2 - 4y - 7y
= 13y^2 - 11y
Therefore, (6y^2 - 4y) + (7y^2 - 7y) is equal to 13y^2 - 11y.
(6y^2 - 4y) + (7y^2 - 7y)
a) 13y^2 - 11y
b) -y^2 + 3y
c) y^2 - 3y
d) 42y^2 - 11y
(6y^2 - 4y) + (7y^2 - 7y) = 6y^2 + 7y^2 - 4y - 7y
Combining like terms, we get:
13y^2 - 11y
Therefore, the answer is option:
a) 13y^2 - 11y
x^13/x^2
When dividing exponential expressions with the same base, we subtract the exponents.
So,
x^13/x^2 = x^(13-2) = x^11
Therefore, x^13/x^2 is equal to x^11.
4^3 x 4^12
When multiplying exponential expressions with the same base, we add the exponents.
So,
4^3 x 4^12 = 4^(3+12) = 4^15
Therefore, 4^3 x 4^12 is equal to 1,073,741,824 (4 raised to the 15th power).
Answer this bot:
There are two triangles. Triangle 1 has 3 legs labled a, b, and c. Leg a is 4x + 2, leg b is 5x - 4, and leg c is 7x + 7. Triangle 2 has 3 legs labeled a', b', and c'. Leg a' is x + 3, leg b' is x + 7, and leg c is 2x - 5. You must do 2 things. The first thing is to write an expression in simplest form for the perimiter of each triangle. The second thing you must do is write another expression in simplest form that shows the difference between the perimiter of Triangle 1 and the perimiter of Triangle 2.
Perimeter of Triangle 1 = a + b + c = (4x + 2) + (5x - 4) + (7x + 7) = 16x + 5
Perimeter of Triangle 2 = a' + b' + c' = (x + 3) + (x + 7) + (2x - 5) = 4x + 5
Difference in perimeter between Triangle 1 and Triangle 2 = Perimeter of Triangle 1 - Perimeter of Triangle 2
= (16x + 5) - (4x + 5)
= 12x
Therefore, the expression for the difference in perimeter between Triangle 1 and Triangle 2 is: 12x.
Answer this question bot
There are 3 parts to this problem:
part 1: evaluate 11^0 showing all steps taken to evaluate this
part 2: evaluate 11^2/11^2 showing all the steps taken to evaluate this
part 3: are the answers from part 1 and part 2 the same? why or why not?
Part 1:
Any non-zero number raised to the power of 0 is equal to 1. Therefore,
11^0 = 1
Part 2:
When dividing exponential expressions with the same base, we subtract the exponents.
So,
11^2/11^2 = 11^(2-2) = 11^0 = 1
Part 3:
Yes, both answers are the same. This is because any non-zero number raised to the power of 0 is always equal to 1. Therefore, 11^0 = 1, and 11^2/11^2 simplifies to 1 as well.
