Answer:
y = 2x + 2
Step-by-step explanation:
First you want to find the slope of the line that these coordinates make. To do this, use the slope formula: (y₂ - y₁) / (x₂ - x₁). I will use the first and last points.
(0, 2) & (6, 14)
Plug in these values:
(14 - 2) / (6 - 0)
Simplify the parentheses.
= (12) / (6)
Simplify the fraction.
12/6
= 2
This is your slope.
Now plug this into the standard slope-intercept equation: y = mx + b
y = 2x + b
b is the y-intercept, or the value of y when x = 0. If y=we look at the table, we can see that when x = 0, y = 2.
Therefore, our b-value is 2.
Plug this into our equation.
y = 2x + 2

9000 invested at 8% compounded annually. In how many years will
the account have grown to $14500
Answers
It will take approximately 6.2 years for the account to grow to $14500 when $9000 is invested at 8% interest compounded annually.
What is the time needed to acquire the accrued amount?The compound interest formula is expressed as:
\(A = P( 1 + \frac{r}{t})^{nt}\)
\(t = \frac{In(\frac{A}{P} )}{n[In(1 + \frac{r}{n} )]}\)
Where A is accrued amount, P is the principal, r is the interest rate and t is time.
Given that:
Principal P = $9,000, compounded annually n = 1, interest rate r = 8%, Accrued amount A = $14500.
Plug these values into the above formula and solve for time t.
\(t = \frac{In(\frac{A}{P} )}{n[In(1 + \frac{r}{n} )]}\\\\t = \frac{In(\frac{14,500}{9,000} )}{1*[In(1 + \frac{0.08}{1} )]}\\\\t = \frac{In(\frac{14,500}{9,000} )}{[In(1 + 0.8 )]}\\\\t = \frac{In(\frac{14,500}{9,000} )}{[In(1.8 )]}\\\\t = 6.197 \ years\)
Therefore, the time required is 6.197 years.

Step-by-step explanation:
Given
Goes through
\(C = (1.5,4)\)
Parallel to AB
\(A = (2,-1)\)
\(B = (4,5)\)
Required
Determine the line equation
First, calculate the slope of AB
\(m = \frac{y_2 - y_1}{x_2 - x_1}\)
\(m = \frac{5--1}{4-2}\)
\(m = \frac{6}{2}\)
\(m = 3\)
The line is said to be parallel to AB. This implies that their slopes are equal.
The equation of the line is then calculated as:
\(y = m(x - x_1) + y_2\)
Where:
\((x_1,y_1) = (1.5,4)\)
So:
\(y = 3*(x - 1.5) + 4\)

The first two steps in determining the solution set of the system of equations, y = x2 – 6x + 12 and y = 2x – 4, algebraically are shown in the table.
Which represents the solution(s) of this system of equations?
(4, 4)
(–4, –12)
(4, 4) and (–4, 12)
(–4, 4) and (4, 12)
Answers
Answer:
(4,4)
Step-by-step explanation:
The solution set of the system of equations can be found by setting the two equations equal to each other and solving for x.
x^2 - 6x + 12 = 2x - 4
x^2 - 8x + 16 = 0
(x - 4)^2 = 0
x = 4
Since both equations in the system are equal to y, we can substitute x = 4 into either equation to find the corresponding value of y.
y = 2x - 4 = 2(4) - 4 = 4
Therefore, the solution of this system of equations is (4, 4).
Therefore, the correct answer is (4, 4).

Answer:
D. -3 and 3
Step-by-step explanation:
We are given an output of 2. This means this is the value we need an input for. We need to find a number(s) that lie on the x axis and when we move up, you get an output of 2.
Option A:
If we are given an input of -2, we start at (-2, 0) and move up until we reach a point on the line. We end up lying on the point (-2, 3). Thus, the output for having an input of -2 is 3 which proves that this answer is incorrect.
Option B:
As stated above -2 has an output of 3 which is wrong. Since we know this, we can eliminate this as an option.
Option C:
If we are given an input of -3, we start at (-3, 0) and move up until we reach a point on the line. We end up lying on the point (-3, 2). Thus, the output for having an input of -2 is 2 which proves that this answer is correct.
Option D:
We know that -3 is a possible input so we just need to check 3 as an input.
If we are given an input of 3, we start at (3, 0) and move up until we reach a point on the line. We end up lying on the point (3, 2). Thus, the output for having an input of 3 is 2 which proves that this answer is also correct.
Since we know that -3 and 3 are possible inputs for an output of 2 on the graph, we need to include them both in our answer. Thus, the answer is D.

.Find the largest subset S on which the given vector - valued function is continuous?
F = ( t/9+t^4, 7t^2-7t+1, ln (t+3))
.
Answers
The largest subset S on which the vector-valued function F is continuous is the interval (-3, ∞).
To find the largest subset S on which the given vector-valued function is continuous, we need to examine the individual component functions and identify any restrictions or conditions that could cause discontinuities.
Component 1: f1(t) = t/(9 + t^4)
This function is a rational function. It will be continuous for all real values of t except where the denominator equals zero: 9 + t^4 = 0. However, there are no real values of t that satisfy this equation, so f1(t) is continuous for all real values of t.
Component 2: f2(t) = 7t^2 - 7t + 1
This function is a polynomial function, and polynomial functions are continuous for all real values of t. Therefore, f2(t) is continuous for all real values of t.
Component 3: f3(t) = ln(t + 3)
The natural logarithm function is defined for the positive values of its argument. Therefore, t + 3 > 0, which implies t > -3. Hence, the function f3(t) is continuous for t > -3.
Taking all these considerations into account.The function is continuous for all values of t greater than -3.

let b=b1, ... , bn be a basis for a vector space v. explain why the b-coordinate vectors of b1, ... , bn are the columns e1, ... , en of the n×n identity matrix.
Answers
In a vector space V, a basis is a set of linearly independent vectors that span the entire vector space. Let's consider a basis B = {b1, b2, ..., bn} for vector space V.
The b-coordinate vectors of b1, b2, ..., bn represent the coordinates of these basis vectors with respect to the basis B. In other words, they represent how each basis vector can be expressed as a linear combination of the basis vectors in B.
Now, let's consider the standard basis for an n-dimensional vector space, which consists of the n column vectors e1, e2, ..., en of the n×n identity matrix. Each column vector ei has a 1 in the ith position and 0s in all other positions.
To show that the b-coordinate vectors of b1, b2, ..., bn are the columns e1, e2, ..., en of the n×n identity matrix, we need to demonstrate two key properties:
Linear Independence: The basis vectors b1, b2, ..., bn are linearly independent, which means no vector in the set can be written as a linear combination of the other vectors. Similarly, the column vectors e1, e2, ..., en of the identity matrix are linearly independent.
Spanning: The basis vectors b1, b2, ..., bn span the entire vector space V, which means any vector in V can be expressed as a linear combination of the basis vectors. Similarly, the column vectors e1, e2, ..., en of the identity matrix span the n-dimensional space.
Since both sets of vectors satisfy these properties, it follows that the b-coordinate vectors of b1, b2, ..., bn are indeed the columns e1, e2, ..., en of the n×n identity matrix.

Jackson is working two summer jobs, making $10 per hour washing cars and $12 per hour landscaping. Last week jackson worked a total of 14 hours and earned a total of $152. Determine the number of hours jackson worked washing cars last week and the number of hours he worked landscaping last week.
Answers
The number of hours Jackson worked washing cars is 8 hours and the number of hours he worked landscaping is 6 hours
The payment of car washing per hour = $10
The payment for landscaping = $12
Total number of hours worked = 14 hours
Number of hours worked in car washing = x
Number of hours worked in landscaping = y
Then the first equation will be
x + y = 14
x = 14 - y
Total amount he earned = $152
Next equation will be
10x + 12y = 152
Here we have to use substitution method
10(14-y) + 12y = 152
140 - 10y +12y = 152
140 + 2y = 152
2y = 152 - 140
2y = 12
y = 12/2
y = 6 hours
Then
x = 14 - y
x = 14 -6
x = 8 hours
Hence, the number of hours Jackson worked washing cars is 8 hours and the number of hours he worked landscaping is 6 hours
