Solution:
Given the first three terms of an arithmetic sequence as;
[tex]-5,-8,-11[/tex]An arithmetic sequence is a sequence with a common difference d, The common difference is the difference between two consecutive terms. Where;
[tex]\begin{gathered} d=a_2-a_1 \\ \text{Where;} \\ a_2=\text{ second term;} \\ a_1=\text{first term} \end{gathered}[/tex]Thus;
[tex]\begin{gathered} d=-8-(-5) \\ d=-8+5 \\ d=-3 \end{gathered}[/tex]Also, the next term of the sequence can be known by adding the common difference to the previous term.
Hence, the next two terms are;
[tex]\begin{gathered} =-11+(-3) \\ =-11-3 \\ =-14 \\ \text{and } \\ =-14+(-3) \\ =-14-3 \\ =-17 \end{gathered}[/tex]FINAL ANSWER:

The given system of inequalities is
[tex]\begin{gathered} y>\frac{3}{2}x-2 \\ y\leq-3x-4 \end{gathered}[/tex]The area of the solution is the area shaded by the 2 colors
Let us check the points
(-2, -5) it lies on the red dashed line
Since the line is dashed, then the points lie on it do not belong to the solution, then
(-2, -5) does not belong to the solution
(-2, -5) is not a solution
(-2, 2) it lies on the blue line
Since the line is solid, then the points that lie on it belong to the solution, then
(-2, 2) is a solution
(0, -4) it is out of the area of both colors, then
(0, -4) is not a solution
(-3, -1) it lies in the area of the common colors, then
(-3, -1) is a solution
(-1, 4) it is out the area of both colors, then
(-1, 4) is not a solution
(-20, 15) is in the area of the common colors, then
(-20, 15) is a solution
(15, 20) it is out the area of both colors, then
(15, 20) is not a solution
Then the solutions of the system are:
(-2, 2), (-3, -1), (-20, 15)
Zach puts $1000 into a savings account earning 5% compound interest for 5 years. How much
interest has Zach earned at the end of the the 5 years?
$_______
Do not enter the dollar sign as part of your answer
The amount of interest Zach earn in 5 years given the principal and interest rate compounded for 5 years is 276.3
What is the amount of interest Zach earned?A = P(1 + r/n)^nt
Where,
A = principal + interestPrincipal, P = $1000Interest rate, r = 5% = 0.05Time, t = 5 yearsNumber of periods, n = 1A = P(1 + r/n)^nt
= 1000(1 + 0.05/1) ^(1×5)
= 1000(1 + 0.05) ^5
= 1000(1.05)^5
= 1000(1.2762815625)
= 1,276.2815625
Approximately,
1,276.3
Hence,
A = principal + interest
1, 276.3 = 1000 + interest
1276.3 - 1000 = interest
Interest = 276.3
Therefore, the amount of interest earned in 5 years is 276.3

What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
As per option (B),
4x - 2y < 12
We can see that the x-intercept is (0, -6), and the y-intercept is (2.5, 0) in the given graph which is determined by substituting the value of x and y is equal to 0 in the equation 4x - 2y = 12.

What does the constant 1.6 reveal about the rate of change of the quantity?
The form of the exponential growth/decay function is
[tex]f(x)=a(1\pm r)^x[/tex]a is the initial amount
r is the rate of growth/decay per x years
We use + with growth and - with decay
Since the given function is
[tex]f(t)=2700(1.6)^{7t}[/tex]Where t is time per week
Compare the two functions
[tex]\begin{gathered} a=2700 \\ (1+r)=1.6 \\ x=7t \end{gathered}[/tex]Since 1.6 is greater than 1, then
The function is growth
Equate 1.6 by (1 + r) to find r
[tex]\begin{gathered} 1+r=1.6 \\ \\ 1-1+r=1.6-1 \\ \\ r=0.6 \end{gathered}[/tex]Change it to percent by multiplying it by 100%
[tex]\begin{gathered} r=0.6\times100\text{ \%} \\ \\ r=60\text{ \%} \end{gathered}[/tex]Since x = 7t then the time is every 7 weeks
The answer is
The function is growing exponentially at a rate of 60% every 7 weeks
Are the graphs of the equations parallel, perpendicular, or neither? y= 2x +6 and y= 1/2x +3
Given the equations:
[tex]\begin{gathered} y=2x+6 \\ y=\frac{1}{2}x+3 \end{gathered}[/tex]The equation has the form of slope - intercept form which is like:
[tex]y=m\cdot x+b[/tex]Where m is the slope and b is y- intercept
So,
The slope of the first equation = 2
The slope of the second equation = 1/2
The graphs of the equations are parallel when the slopes are equal
The graphs of the equations are perpendicular when the product of the slopes = -1
so,
the slopes are not equal
The product of the slopes = 2 * 1/2 = 1
So, the graphs of the equations are neither parallel nor perpendicular.

Answer:
47quarters and 20 nickel
Explanation:
Let the number of quarters be x
Let the number of nickels be y
If there are 67 coins in the jar, then;
x + y = 67 ....1
1 quarter = 0.25x
1 nickel = 0.05y
If the total value of the coins in the jar is $12.75, then;
0.25x + 0.05y = 12.75 ....2
Multiply through by 100
25x + 5y = 1275 ....2
Solve 1 and 2 simultaneously
x + y = 67 ....1 * 25
25x + 5y = 1275 ....2 * 1
Using Elimination method
________________________
25x + 25y = 1,675
25x + 5y = 1275
Subtract
25y - 5y = 1675 - 1275
20y = 400
y = 400/20
y = 20
Substitute y = 20 into equation 1;
From 1; x + y = 67
x + 20 = 67
x = 67 - 20
x = 47
This means there are 47quarters and 20 nickel.

EXPLANATION
Given the equation y= -1.5x + 3
In order to get a system with just one solution, the viable options are those that allow both lines to intersect in just one point.
Those equations are:
y= -1.5x
y=-2x + 3
The system of equations y=-1.5x+3 and y=-1.5x+6 has no solution because subtracting both expressions give us the result 3=0
The system y=-1.5x+3 and 2y = -3x+6, or in the same way the system y=-1.5x+3 and 2y + 3x = 6 has no solution because they have the same expression.

Given:-
From a window 100ft above the ground in building A, the top and bottom of building B are sighted so that the angles are 70 degrees and 30 degrees respectively.
To find:-
The height of building B.
So now, the image of the given data is,
So now we find the value of PS. so we get,
[tex]\begin{gathered} \tan \text{ 30=}\frac{100}{PS} \\ \frac{1}{\sqrt[]{3}}=\frac{100}{PS} \\ PS=100\sqrt[]{3} \end{gathered}[/tex]So now we find the height of QS,
[tex]\begin{gathered} \tan \text{ 70=}\frac{QS}{PS} \\ 2.7474=\frac{QS}{100\sqrt[]{3}} \\ QS=100\sqrt[]{3}\times2.7474 \\ QS=475.84 \end{gathered}[/tex]So the total height is,
