Based on the total amount that Karen spent in one week at the Starbucks, the cost of one latte was $6.83
What was the cost of one latte?Karen left a tip of a dollar every day she bought a Latte so this comes to:
= 1 x 5 days
= $5
The cost of a single latte is therefore:
= (Total amount spent - Total tips) / Number of days
= (39.15 - 5) / 5
= 34.15 / 5
= $6.83
In conclusion, a single latte at the Starbucks to Karen for the weekdays was $6.83.

The tables 2, 3 and 4 represent linear equations. (Correct choice: D)
Which tables do represent linear functions?
Algebraically speaking, linear functions are represented by a expression of the form y = m · x + b, where m is the slope of the function and b is the y-intercept of the line. Slope can be interpretated in accordance with the secant line formula:
m = Δy / Δ x
Where:
Δx - Change in independent variable.Δy - Change in dependent variable.In other words, a table represents a linear function if for all difference between two consecutive values in x means the same change for two corresponding values in f(x).
After a quick inspection, we find that tables 2, 3 and 4 represent linear as they show the following features:

how the value of each digit was affected by the division.
What is the equation of the line that passes through the point (-1,6)and has a slope of −1
Answer:
y = -x + 5
Step-by-step explanation:
slop m = -1, x = -1, y = 6
y = mx + b
6 = (-1)(-1) + b
6 = 1 + b
b = 5
so y = -x + 5
Write the equation of the line in slope-intercept form.
4x=y-11
The equation of the line in slope-intercept form is y = 4x + 11 .
The equation of a line in slope-intercept form can be written as follows,
y = mx + c equation 1
m in the above equation represents slope of the line and c represents the intercept.
The given equation is 4x = y - 11 .
To get the equation of the line in slope-intercept form we need to convert the given equation in the format of equation of a straight line i.e., equation1. So, now we will rearrange the given equation as
4x = y - 11
On adding 11 on both sides in above equation, we will get
y = 4x + 11 equation 2
On equating equation 1 and equation 2, we will get
Slope of the line = m = 4
Intercept = c = 11
The equation of the line in slope-intercept form is y = 4x + 11 .

The cross-section of a lean-to shelter is in the shape of a triangle. The base of the
triangle is 6 feet more than twice its height. If the area of the triangle is 88 square feet,determine the length of the base and the height of the triangle in feet
Answer:
Step-by-step explanation:
Givens
Let the height = x
Let the base = 2*x +6
Let the area = 88 square feet.
Formula
A = Base * height / 2
Solution
88 = (2x + 6)*x/2 Multiply both sides by 2
88*2 = (2x+6)*2*x/2 Combine
176 = (2x + 6)*x Remove the brackets
176 = 2x^2 + 6x Subtract 176 from both sides
0 = 2x^2 + 6x - 176 This factors without the quadratic
0 = (2) (x^2 + 3x - 88)
0 = 2 (x +11)(x - 8)
Note: x + 11 has no meaning. Measurements of this type cannot be minus. What is - 11 feet.

We know that,
Exponential Decaying factor is [tex]y = ab^{x}[/tex]
Where, 0<b<1
The decay rate is expressed as a percentage. We convert it to a decimal by simply reducing the percent and dividing it by 100.
Growth factor is the factor by which a quantity multiplies itself over time. Growth rate is the addend by which a quantity increases (or decreases) over time.
Here,
Option(1) : [tex]y = (0.3)(0.5)^{x}[/tex]
Then, 0.5 < 1 (0.5 means 50%)

Hence, [tex]y = (0.3) (0.5)^{x}[/tex] is an exponential decay factor of 50%.
Option(2) : [tex]y = 2000(\frac{4}{5}) ^{x}[/tex]
Then, 4/5 < 1
⇒ 0.8 < 1
So, [tex]y = 2000(\frac{4}{5} )^{x}[/tex] is an exponential decay factor.
Hence, [tex]y = 2000(\frac{4}{5} )^{x}[/tex] is an exponential decay factor of 15%.
Option(3) : [tex]y = 800 (1.15)^{x}[/tex]
Then, 1.15 > 1
So, [tex]y = 800 (1.15)^{x}[/tex] is an not exponential decay factor.
Hence, [tex]y = 800 (1.15)^{x}[/tex] is an not exponential decay factor of 115%, so it is not decay factor, then the related to growth factor 15%.
Option(4) : [tex]y = 1200 (1.05)^{x}[/tex]
Then, 1.05 > 1
So, [tex]y = 1200 (1.05)^{x}[/tex] is an not exponential decay factor.
Hence, [tex]y = 1200 (1.05)^{x}[/tex] is an not exponential decay factor of 105%, so it is not decay factor, then the related to growth factor 5%.
Option(5) : [tex]y = 3(0.85)^{x}[/tex]
Then, 0.85 < 1
So, [tex]y = 3(0.85)^{x}[/tex] is an exponential decay factor.
Hence, [tex]y = 3(0.85)^{x}[/tex] is an exponential decay factor of 85%, then the related to 20%.
Therefore,
[tex]y = (0.3) (0.5)^{x}[/tex] is an exponential decay factor of 50%.
[tex]y = 2000(\frac{4}{5} )^{x}[/tex] is an exponential decay factor of 15%.

b. Do transformations of the form y=|x|+k affect the axis of symmetry? Explain.
A line that bisects or cuts an objects into two equals parts is called the axis of symmetry for that object. The axis of symmetry creates a mirror-like reflection of each side of the object.
The function f(x) = |x| is called an absolute value function. The highest or lowest point on the graph of the absolute value function is called the vertex. The absolute value graph has an axis of symmetry through the vertices.
The axis of symmetry (x=0 or y-axis) is the line that divides the graph into two congruent halves. Translate is a transformation that moves the graph horizontally or vertically, but does not change its overall shape or orientation.
So, it does not affect the axis of symmetrical. Is symmetrical about the Y axis (axis of symmetry).

2. The slope of the perpendicular line is .
3. Substitute the point and the new slope into point-slope form to get y – 5 = (x – (–6)).
4. Simplifying, the line is y – 5 = (x + 6).
Is Simon’s work correct?
No, the slope of the line 3x + 2y = –11 is not .
No, the slope of the line perpendicular to the line 3x + 2y = –11 should be .
No, he did not substitute the point and the slope into point-slope form correctly.
Yes, the work is correct.
The answer would be: B. No, the slope of the line perpendicular to the line 3x + 2y = –11 should be 2/3.
What if the Slope of Perpendicular Lines?The equation in slope-intercept form of a line is, y = mx + b, where we have the slope value as m. If two lines are perpendicular, the value of their slope (m) will be negative reciprocals to each other.
Rewriting the equation, 3x + 2y = -11 in slope-intercept form, we would have:
2y = -3x - 11
y = -3/2x - 11/2
The slope (m) is, -3/2. The negative reciprocal is, 2/3.
Therefore, the slope of the line that is perpendicular to the given line would be: 2/3.
Thus, the answer would be: B. No, the slope of the line perpendicular to the line 3x + 2y = –11 should be 2/3.
