I needddd helpppp asappppp
Answer:
Step-by-step explanation:
Part A: Slope of parallel lines are equal.
4x - 3y - 7 = 0 ⇔ y = [tex]\frac{4}{3}[/tex] x - [tex]\frac{7}{3}[/tex]
m = [tex]\frac{4}{3}[/tex]
y - 3 = [tex]\frac{4}{3}[/tex] ( x + 2 ) ⇔ y = [tex]\frac{4}{3}[/tex] x + [tex]\frac{17}{3}[/tex] ⇔ 4x - 3y + 17 = 0
Part B: Slope of perpendicular lines are opposite reciprocal.
[tex]m_{1}[/tex] × [tex]m_{2}[/tex] = - 1
[tex]m_{1}[/tex] = [tex]\frac{4}{3}[/tex]
[tex]m_{2}[/tex] = - [tex]\frac{3}{4}[/tex]
y - 3 = - [tex]\frac{3}{4}[/tex] ( x + 2 ) ⇔ y = - [tex]\frac{3}{4}[/tex] x + [tex]\frac{3}{2}[/tex] ⇔ 3x + 4y - 6 = 0

Divide 3900 between Kunal and Kirti in the ratio 15:11.
Answer:
ilig
Step-by-step explanation:
Answer:
Kunal: 2250
Kirti: 1650
Step-by-step explanation:
15 + 11 = 26
3900/26 = 150
150 times 15 = 2250
150 times 11 = 1650
Using the compound interest formula, the "n" is what value when compounded annually?
Answer:
n=1
Step-by-step explanation:
N is the number of times per year
Annually would be one time per year so n =1
Answer:
If interest is compounded yearly, then n = 1; if semi-annually, then n = 2; quarterly, then n = 4; monthly, then n = 12; weekly, then n = 52; daily, then n = 365; and so forth, regardless of the number of years involved. Also, "t" must be expressed in years, because interest rates are expressed that way.

Choose the correct simplification of (9xy^5)^2.
A) 18x^2y^10
B) 18x^2y^7
C) 81x^2y^7
D) 81x^2y^10
Answer:
D) 81x²y¹⁰
Step-by-step explanation:
(9xy⁵)²
Because all of 9xy⁵ are in the parentheses, each component is raised to the 2nd degree.
(9)² = 81
(x)² = x²
(y⁵)² = y¹⁰ -- When you raise an exponent to another exponent, you multiply the exponents.
Now combine the components.
D) 81x²y¹⁰

Solve the inequality for x and identify the graph of its solution.
[1x + 1]< 2
Choose the answer that gives both the correct solution and the correct graph.
Answer:
x<1
Step-by-step explanation:
[1x + 1]< 2
Simplify both sides of the inequality.
x+1<2
Subtract 1 from both sides.
x+1−1<2−1
x<1
Answer:
x<1

3. Explain why the polynomial 34 + 5x3 - 7x2 + 3x has a degree 3 and not 4.
Answer:
See explanation below
Step-by-step explanation:
The degree of a polynomial is the LARGEST power at which the variable/s appear in their expression.
Notice that in the given polynomial, the highest power for the variable x is 3, from the term 5 x^3.
There is no other term with higher power for x.
The variable appear in the expression [tex]3^{4} + 5x^{3} + 7x^{2} + 3x[/tex] x which has highest power 3 not 4 .
We have to explain, why the polynomial [tex]3^{4} + 5x^{3} + 7x^{2} + 3x[/tex] has a degree 3 and not 4.
According to the question,
A polynomial's degree is the highest or the greatest power of a variable in a polynomial equation.
The degree of a polynomial is the largest power at which the variable appear in their expression.
[tex]Polynomial = 3^{4} + 5x^{3} + 7x^{2} + 3x[/tex]
The given polynomial, the highest power for the variable x is 3, from 5 .
Hence, The variable appear in the expression [tex]3^{4} + 5x^{3} + 7x^{2} + 3x[/tex] x which has highest power 3 not 4 .

(25m + 22) + (9m) = ?
Answer:
Step-by-step explanation:
Simplifying
25m + 22 = 9m
Reorder the terms:
22 + 25m = 9m
Solving
22 + 25m = 9m
Solving for variable 'm'.
Move all terms containing m to the left, all other terms to the right.
Add '-9m' to each side of the equation.
22 + 25m + -9m = 9m + -9m
Combine like terms: 25m + -9m = 16m
22 + 16m = 9m + -9m
Combine like terms: 9m + -9m = 0
22 + 16m = 0
Add '-22' to each side of the equation.
22 + -22 + 16m = 0 + -22
Combine like terms: 22 + -22 = 0
0 + 16m = 0 + -22
16m = 0 + -22
Combine like terms: 0 + -22 = -22
16m = -22
Divide each side by '16'.
m = -1.375
Simplifying
m = -1.375
