Answer:
x = -4
Step-by-step explanation:
Equation of the Line
It can be written in the slope-intercept form as:
y = mx + b
Where m is the slope of the line and b is the y-intercept.
For horizontal lines, m=0. For slanted lines, m can have any real value.
Vertical lines have an infinite slope and the above equation cannot be used.
Vertical lines have a fixed value for x, thus the equation is:
x = h
If the vertical line goes through the point (-4,1), then its equation is:
x = -4

Malcolm and Theo's families are both traveling to the same vacation resort.
The equation d=65t models the distance, d, that Malcolm's family travels after t hours.
The graph below shows the relationship between the distance and the amount of time that Theo's family traveled.
Answers
Solution :
Equation for Malcom's family travels after t hours is d = 65 t
From the graph, equation for Theo's family travels after travels after t hours is
[tex]$d=\frac{225}{4.5}t$[/tex]
[tex]$d=50 t$[/tex]
For Malcom's family, speed [tex]$= \frac{d}{t}$[/tex] = 65 miles per hour
For Theo's family, speed [tex]$= \frac{d}{t}$[/tex] = 50 miles per hour
Malcom's family traveled faster than Theo's family by
= (65-50) miles per hour
= 15 miles per hour
A professor at a local university noted that the exam grades of her students were normally distributed with a mean of 73 and a standard deviation of 11. A. The professor has informed us that 7.93 percent ofher students received grades of A. What is the minimum scoreneeded to receive a grade of A?B. Students who made 57.93 or lower on the exam failedthe course. What percent of students failed the course?C. If 69.5% of the students received grades of C or better, what is the minimum score of those who received C's?
Answers
Answer:
88.51
0.085343
67.39
Step-by-step explanation:
Given a normal distribution :
Mean (m) = 73
Standard deviation (s) = 11
Percentage A's = 7.93% = 0.0793
Minimum score needed to receive A :
Using the Z formula
Zscore corresponding to 0.0793 = 1.41
P(x ≥ x) :
Z = (x - m) / s
1.41 = (x - 73) / 11
11* 1.41 = x - 73
15.51 = x - 73
x = 15. 51 + 73
x = 88.51
B. Students who made 57.93 or lower on the exam failedthe course. What percent of students failed the course?
P(x ≤ 57.93)
Z = (x - m) / s
Z = (57.93 - 73) / 11
Z = - 15.07 / 11
Z = - 1.37
P( Z ≤ - 1.37) = 0.085343 ( Z probability calculator)
C.) If 69.5% of the students received grades of C or better, what is the minimum score of those who received C's?
Minimum score of those who received C
Zscore corresponding to 0.695 = -0.51 (Z probability calculator)
Z = (x - m) / s
-0.51 = (x - 73) / 11
11* - 0.51= x - 73
-5.61 = x - 73
x = - 5.61 + 73
x = 67.39

Answers
Let's say you have two line segments, AB and CD which bisect each other at point E. Explain why AC = DB.
Answers
Answer:
[tex]AC=DB[/tex]
(corresponding parts of congruent triangles are equal)
Step-by-step explanation:
Consider triangles ACE and BDE.
As AB and CD bisect each other at point E,
[tex]AE=BE\\CE=DE[/tex]
As AB and CD intersect each other at point E and vertically opposite angles are equal,
∠AEC = ∠BED
So,
ΔAEC ≅ ΔBED (Using SAS congruence criteria)
(According to SAS congruence criteria, if two sides and the included angle of one triangle are equal to the corresponding two sides and the included angle of another triangle then the two triangles are said to be congruent.)
Hence,
[tex]AC=DB[/tex]
(corresponding parts of congruent triangles are equal)
When segments AB and CD bisect each other at point E, the two triangles formed, [tex]\triangle AEC $ and $ \triangle BED[/tex], are congruent to each other SAS Congruence Theorem, therefore, AC = DB.
Recall:
Congruent triangles have equal sides and equal angles that corresponds to each other.Line segments AB bisecting line segment CD at point E will give us the triangles AEC and BED if we join A to C, and B to D.
Thus, the following information can be deduced from the image of both triangles shown in the attachment below:
[tex]EC \cong ED\\\\AE \cong BE[/tex] (congruent segments)
[tex]\angle AEC \cong \angle BED[/tex] (vertical angles)
From the above stated, [tex]\mathbf{\triangle AEC \cong \triangle BED}[/tex] by the SAS Congruence Theorem.
Since both triangles are congruent, all their corresponding sides would be congruent, therefore AC = DB.
In summary, when segments AB and CD bisect each other at point E, the two triangles formed, [tex]\triangle AEC $ and $ \triangle BED[/tex], are congruent to each other SAS Congruence Theorem, therefore, AC = DB.

A principal of $4500 is invested at 4.25% interest, compounded annually. How much will the investment be worth after 12 years?
Use the calculator provided and round your answer to the nearest dollar.
Answers
The money will be worth 7412 at the end of the 12th year.
What is compound interest?Compound interest is the interest that accrues on a loan or deposit on both the initial interests and principal.
Analysis:
To calculate the amount after 12 years we use the compound interest formula, A = P[tex](1 + \frac{r}{100} )^{n}[/tex]
where A = amount after a period of time, P = initial principal = 4500, r = rate = 4.25, n = number of years = 12.
A = 4500[tex](1 + \frac{4.25}{100} )^{12}[/tex] = 7412
In conclusion, 7412 dollar will be realized at the end of the 12th year.
