Answer:
see attached
Step-by-step explanation:
For values of x less than zero, the graph of the function is a graph of the line
y = -x
Because the function is defined by this expression at x=0, there will be a solid dot at the end of the line there, at (0, 0).
__
For values of x greater than 0, the graph of the function is a graph of the line
y = -x -2
This line has the same -1 slope as before, but has a y-intercept of -2. The function is not actually defined as (0, -2), so there is an open circle at the end of the line there.

Marc wants to buy a bestselling book and a DVD of the movie based on the book. He has $30 to spend. Find the estimated total cost of the two items by rounding their prices to the nearest dollar. Will Marc be able to purchase both items with the money he has?
Prices, including taxes: Book: $10.58 and DVD: $19.50
The estimated total to the nearest dollar is $29, so he can afford both items.
The estimated total to the nearest dollar is $31, so he can afford both items.
The estimated total to the nearest dollar is $29, so he cannot afford both items.
The estimated total to the nearest dollar is $31, so he cannot afford both items.
Answers
Answer:
The estimated total to the nearest dollar is $31, so he cannot afford both items.
Step-by-step explanation:
10.58 rounded is 11
19.50 rounded is 20
11+20=31
Answer:
I think it would be last one. Based on the idea that 10.58 would round up to 11.00, and the DVD would add up to 20.oo
that would equal 31.00, and he only has 30.00 to spend.
So I would say D.

[tex]Area =\frac{10x + 15}{2}[/tex] in both cases
Step-by-step explanation:
See attachment for complete question.
From the attachment, we have the following given parameters
Green Section: Dimension: x by 2
Orange Section: Dimension: 2 by [tex]1\frac{1}{2}[/tex]
Purple Section: Dimension: 3 by (x + [tex]1\frac{1}{2}[/tex])
Solving (a): Area of the flag as a sum of each section
We simply calculate the area of each section.
[tex]Area = Length * Width[/tex]
For the green section;
[tex]Area = x * 2[/tex]
[tex]Area = 2x[/tex]
For the orange section
[tex]Area = 2 * 1\frac{1}{2}[/tex]
[tex]Area = 3[/tex]
For the purple section
[tex]Area = 3 * (x + 1\frac{1}{2})[/tex]
[tex]Area = 3 * (x + \frac{3}{2})[/tex]
[tex]Area = 3x + \frac{9}{2}[/tex]
Total Area = Sum of the above areas
[tex]Area = 2x + 3 + 3x + \frac{9}{2}[/tex]
Collect Like Terms
[tex]Area = 2x + 3x+ 3 + \frac{9}{2}\\[/tex]
[tex]Area = 5x+ \frac{6+9}{2}[/tex]
[tex]Area = 5x+ \frac{15}{2}[/tex]
[tex]Area =\frac{10x + 15}{2}[/tex]
Solving (b): Area of the flag as a product
From the attachment,
[tex]Length = 2 + 3[/tex]
[tex]Length = 5[/tex]
[tex]Width = x + 1\frac{1}{2}[/tex]
[tex]Area = Length * Width[/tex]
[tex]Area = 5(x + 1\frac{1}{2})[/tex]
[tex]Area = 5(x + \frac{3}{2})[/tex]
[tex]Area = 5x + \frac{15}{2}[/tex]
Take LCM
[tex]Area = \frac{10x + 15}{2}[/tex]

please help fast. - a pair of equations are shown below:
y = 7x - 8
y = 5x - 2
Answers
Answer:
see explanation
Step-by-step explanation:
Given the 2 equations
y = 7x - 8 → (1)
y = 5x - 2 → (2)
A
Solving by substitution
Substitute y = 7x - 8 into (1)
7x - 8 = 5x - 2 ( subtract 5x from both sides )
2x - 8 = - 2 ( add 8 to both sides )
2x = 6 ( divide both sides by 2 )
x = 3
Substitute x = 3 into either of the 2 equations and evaluate for y
Substituting into (1)
y = 7(3) - 8 = 21 - 8 = 13
Solution is (3, 13 )
B
The point of intersection of the graph of the 2 equations is the solution to the above equations.
That is point of intersection = (3, 13 )
Write a linear function f with f(0)=3 and f(−6)=3.
f(x)=
Answers
Answer:
y = 3
Step-by-step explanation:
The equation of a line is;
y = mx + c
Now, when f(0) = 3, it means at x = 0, y = 3.
Thus;
3 = 0 + c
3 = c
Also, f(−6) = 3
Thus;
3 = -6m + 3
6m = 3 - 3
6m = 0
m = 0/6
m = 0
Thus,equation is;
y = c
y = 3

In kite ABCD, mZBAE = 28° and mZBCE = 58°. Find mLABE.
Answers
Answer:
[tex]m\angle ABE=52^\circ[/tex]
Step-by-step explanation:
Angles and Lines
The figure shows a kite ABCD where the following data is given:
[tex]m\BAE=28^\circ[/tex]
[tex]m\BCE=58^\circ[/tex]
We also know
[tex]BC\cong CD[/tex]
[tex]AB\cong AD[/tex]
Since triangle BCD is isosceles, it follows that:
[tex]m\angle CBE=m\angle CDE[/tex]
And triangles BCD and DCE are congruent.
Thus:
[tex]m\angle BCE=m\angle DCE=58^\circ[/tex]
And also:
[tex]m\angle BCE=58^\circ+58^\circ=116^\circ[/tex]
Since the sum of internal angles of BCD is 180°
[tex]m\angle CDE=m\angle CBE= ( 180 - 116 ) / 2=32^\circ[/tex]
The sum of angles of triangle CDE is 180°, thus
[tex]m\angle CED=180^\circ - 32^\circ - 58^\circ = 90^\circ[/tex]
Angles CED and BEA are vertical (opposite), thus:
[tex]m\angle BCE=m\angle CED= 90^\circ[/tex]
Finally, since the sum of the angles of triangle ABE is 180°
[tex]m\angle ABE= 180 - 90 - m\angle BAE[/tex]
[tex]m\angle ABE= 180^\circ - 90^\circ - 28^\circ = 52^\circ[/tex]
[tex]\mathbf{m\angle ABE=52^\circ}[/tex]

He claims that at the 90% confidence level, his confidence interval contains µ. Is his claim true or false? B) Sam computed a 95% confidence interval for µ from a specific random sample. His confidence interval was 10.1 < µ < 12.2. He claims that the probability that µ is in this interval is 0.95. Is his claim true or false? C) If we fail to reject (i.E., "accept") the null hypothesis, this means that we have proved it to be true beyond all doubt. Is this true or false?

Answer:
A) True , B) True , C) False
Step-by-step explanation:
A) True : Confidence Interval is the interval range around sample statistic, which is certain by extent of confidence level, to consist the actual population parameter.
B) True : Confidence Interval is the interval range around sample statistic, which is certain by extent of confidence level, to consist the actual population parameter.
C) False : Null Hypothesis can be accepted, despite of being actually false. This is called Type 2 Error.
