The equation of the line passing through point P(-1,-4) that is parallel to y = -6x + 8 is y = -6x - 10.
What is a straight line?A straight line is made up of an infinite number of points connected at their ends.
Any straight line's slope, "m," is determined by:
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
The slope of the line y = -6x + 8
m = -6
The slope of the line passing point P (-1,-4)
M = -6
y - (-4) = -6(x - (-1))
y + 4 = -6(x + 1)
y = -6x - 10
Thus, the equation of the line passing through point P(-1,-4) that is parallel to y = -6x + 8 is y = -6x - 10.

Substitute n = 10 into the equation of each given answer option:
[tex]\begin{aligned}\textsf{Option A}: \quad P(10)&=10^2+4.3\\ & =100+4.3\\&=104.3\end{aligned}[/tex]

Answer:
its 3 because 4^-n=1/256
We move all terms to the left:
4^-n-(1/256)=0
We add all the numbers together, and all the variables
-n+4^-(+1/256)=0
We add all the numbers together, and all the variables
-1n-(+1/256)=0
We get rid of parentheses
-1n-1/256=0
We multiply all the terms by the denominator
-1n*256-1=0
We multiply elements
-256n-1=0
We move all terms containing n to the left, all other terms to the right
-256n=1
n=1/-256

Kevin has x dollars in an account that pays 2.2% interest, compounds quarterly. Express his balance after one quarter algebraically
Balance of Kevin after 1 quarter will be 1.0055(x)
What is quarterly compounded compound interest?Compound interest is interest that is calculated using both the starting amount and the interest that has accrued over time.
Interest is considered to be compounded quarterly if it is compounded four times each year.
If interest is compounded four times or quarterly each year, the formula for the amount at time t is as follows.
A = P( ( 1 + (r/4))⁴ⁿ
A = Accumulated amount
P= Principal amount
r = interest rate
n = time
Given that Kevin has x dollars in an account that pays 2.2% interest, compounds quarterly
∴ P = x
r = 2.2% = 2.2/100
To find balance after one quarter , i.e. time n = 1/4 year
⇒ Balance = accumulated amount =$ x(1 + 2.2/400)¹ = $ 1.0055(x)
Therefore, Balance of Kevin after 1 quarter will be 1.0055(x)

Mike says the opposite of 5 is –5 and the absolute value of 5 is –5. Is he correct?
Use the drop-down menus to explain your answer.
I don't know what the dropdown menus are, but Mike is half-correct. The opposite of a number is the number with the opposite sign, so the opposite of 5 is -5. But the absolute value of a number is its distance from zero on a number line, and distances can't be negative, so the absolute value of 5 is 5, not -5.

Given: AB = 3y - 1, BC = 7y, AC = 29
Prove: AB = 8
Hence proved that triangle AB = 3(3) - 1 = 9 - 1 = 8.
What is triangle?A polygon with three edges and three vertices is called a triangle. It is one of the fundamental geometric shapes. Triangle ABC is the display style for a triangle with vertices A, B, and C. In Euclidean geometry, any three points that are not collinear produce a singular triangle and a singular plane (i.e. a two-dimensional Euclidean space). In other words, every triangle is contained in a plane, and there is only one plane that contains that triangle. All triangles are enclosed in a single plane if all of geometry is the Euclidean plane, however this is no longer true in higher-dimensional Euclidean spaces. Except when otherwise specified, this article discusses triangles in Euclidean geometry, namely the Euclidean plane.
Given that,
AB + AC = AC
3y - 1 + 7y = 29
10y = 29 + 1 = 30
y = 30/10 = 3
Therefore, AB = 3(3) - 1 = 9 - 1 = 8.

A triangle has three sides: AB, BC, CA. We know that angle A is greater than angle C. Find the range for side AC.
A) AB< CA< BC
B) BC- AB < CA < AB + BC
C) BC< CA< AB
D) AB + BC < CA < BC- AB
Answer:
BC- AB < CA < AB + BC
Step-by-step explanation:
The sides opposite the larger angles are longer than the sides opposite smaller angles.
So, BC (opposite < A) is longer than AB (opposite < C) so,
BC > AB
The other side AC cannot be greater than AB + BC, otherwise the triangle would not exist, so,
AC < AB + BC
Also, CA > BC - AB
The range for AC is
BC- AB < CA < AB + BC

4x + 3 = 23 Subtract 3 from both sides
4x + 3-3 = 23-3 Combine
4x = 20 Divide by 4
4x/4 = 20/4

Find the 10th term of the geometric sequence 8,-16,32,…
Answer: -4096
Step-by-step explanation: Use the geometric sequence formula to find the 10th term (image attached). So, the 10th term = 8(-2)^9
Note: the common ratio can be found by 2ndterm/1stterm
Answer:
a₁₀ = -4096
Step-by-step explanation:
Geometric sequence
General form of a geometric sequence:
[tex]\boxed{a_n=ar^{n-1}}[/tex]
where:
aₙ is the nth term.a is the first term.r is the common ratio.n is the position of the term.Given terms of the geometric sequence:
a₁ = 8a₂ = -16a₃ = 32To find the common ratio (r), divide consecutive terms:
[tex]\implies \dfrac{a_3}{a_2}=\dfrac{32}{-16}=-2[/tex]
Substitute the values of a and r into the formula to create an equation for the nth term of the sequence:
[tex]\implies a_n=8(-2)^{n-1}[/tex]
To find the 10th term of the sequence, substitute n = 10 into the equation:
[tex]\begin{aligned}\implies a_{10}&=8(-2)^{10-1}\\&=8(-2)^{9}\\&=8(-512)\\&=-4096\end{aligned}[/tex]

the sum of simple interest and compound interest of a certain interest on a sum of money for 2 years at the rate of 7% p.a is Rs 85470. by how much percent the compound interest is more than the simple interest?
Answer: 3.3%
Step-by-step explanation:
Principal not given.
SI = PRT/100
CI = P(1+R/100)^T -
SI + CI = 85470
[P×7×2]//100 + P [1+ (7/100)]^2 = 85470
on solving: P = 3,00,000
P = 300000 SI for 2 years = 42000

Show that quadrilateral ABCD is a parallelogram.
Slope of AB = 2; Slope of DC = 2
Slope of AD = -1/2; Slope of BC = -1/2
Both pairs of opposite sides are parallel because they have the same slope, therefore, quadrilateral ABCD is a parallelogram.
What is a Parallelogram?A parallelogram is a quadrilateral that has two pairs of opposite sides that have the same lengths and are parallel to each other.
Since the opposite sides of a parallelogram are parallel, therefore, they have the same slope value.
Slope = change in y / change in x.
Find the slope of AB and DC. then AD and BC:
Slope of AB = (-2 - 2)/(-3 -(-1)) = -4/-2
Slope of AB = 2
Slope of DC = (-3 - 1)/(-1 - 1) = -4/-2
Slope of DC = 2
Slope of AD = (-3 -(-2))/(-1 -(-3)) = -1/2
Slope of AD = -1/2
Slope of BC = (2 - 1)/(-1 - 1) = 1/-2
Slope of BC = -1/2
Therefore, since AB and DC have the same slope, they are parallel, so also is AD and BC parallel because they have the same slope, therefore, quadrilateral ABCD is a parallelogram.
