Answer:
C
Step-by-step explanation:
It's C because, -8 - (-13) is the same as the equation shown above. You have to multiply the two negatives since there is a parenthesis, so it becomes. -8 + 13.

what is the slope line perpendicular to the equation 4x+3y=9
Answer:
m=3/4
Step-by-step explanation:
first, let's put the line 4x+3y=9 from standard form (ax+by=c) into slope-intercept form (y=mx+b)
we have the equation 4x+3y=9
subtract 4x from both sides
3y=-4x+9
divide by 3
y=-4/3x+3
perpendicular lines have slopes that are negative and reciprocal. If the slopes are multiplied together, the result is -1
so to find the slope of the line perpendicular to the line y=-4/3x+3, we can take the slope of y=-4/3x+3 (-4/3) multiply it by a variable (this is our unknown value), and have that set to -1
(m is the slope value)
-4/3m=-1
multiply by -3/4
m=3/4
therefore the slope of the perpendicular line is 3/4
hope this helps!! :)

Answer:
The last one.
Step-by-step explanation:
You can begin by dividing by - 2
-2*abs(x) =-6
-2*abs(x)/-2 = - 6/-2
abs(x) = 3
So x can be -3 or 3. Both are solutions

1) find the total of candies
3 + 6 + 5 + 2 + 8 = 24
2) divide the number of yellow candies for the total amount of candies
5/24 = 0.21 (correct)
3) use a proportion
6 : 24 = x : 200
x = (200 *6) / 24 = 50 (correct)

In June, Cory begins to save money for a video game and a TV he wants to buy in December. He starts with $24. Each month he plans to save 10% more than
the previous month. How much money will he have at the end of December?
A. $203.74
B. $177.34
C. $227.69
D. $185.22
Answer:
$185.17
Step-by-step explanation:
The monthly dollar amounts saved here form a geometric progression, since each new amount is derived by multiplying the previous amount by 1.10. This 1.10 is r, the common ratio. The first term is $24 and there will be 5 more terms (June through December is 6 months).
The general formula for individual terms of a geometric series is A(n) = A(1) + r^(n - 1).
Here, with A(1) = $24 (the first term), r =1.10 and n = 6, we'd get $38.65 (the 6th and last term). Following the same procedure, we'd find that the 6 terms will have the values $24, $26.40, $29.04, $31.94, $35.14. $38.65.
Finally, we add these up. We get the sum $185.17.
Fortunately, there's a formula that makes the calculations go much faster: "sum of a geometric sequence." This formula is:
1 - r ^n
a(1)*--------------
1 - r
Here, a(1) = $24 and r = 1.10, and so the sum of the first 6 terms of this geometric sequence is
1 - 1.10^6
$24*---------------- = $185.17
1 - 1.10

Step-by-step explanation:
Miguel and Bartholomew each have credit card debt. Miguel owes $2000 and makes a monthly payments, reducing his debt by $250 per month. Bartholomew owes $1500 and makes monthly payments, reducing his debt by $150 per month. Let m represent The number of months and b represent the balance on the credit card account in dollars. Write a system of 2 equations to represent this situation. When will Miguel and Bartholomew owe the same amount of money?
Answer:
Miguel:
b = 2000 - 250m
Bartholomew:
b = 1500 - 150m
When m = 5
Step-by-step explanation:
Let
m = The number of months
b = balance on the credit card account in dollars.
Miguel owes $2000 and makes a monthly payments, reducing his debt by $250 per month.
Miguel:
b = 2000 - 250m
Bartholomew owes $1500 and makes monthly payments, reducing his debt by $150 per month
Bartholomew:
b = 1500 - 150m
When will Miguel and Bartholomew owe the same amount of money?
Miguel balance = Bartholomew balance
2000 - 250m = 1500 - 150m
2000 - 1500 = -150m + 250m
500 = 100m
m = 500/100
m = 5 months
The grade distribution for students in the introductory statistics class at a local community college are displayed in the table. In this table, A = 4, B = 3, etc. Let X represent the grade for a randomly selected student.
A 2-column table with 5 rows. Column 1 is labeled grade with entries 4, 3, 2, 1, 0. Column 2 is labeled probability with entries 0.43, 0.31, 0.17, 0.05, 0.04.
What is the probability that a randomly selected student earned a C or better?
0.17
0.26
0.48
0.91
Considering the given discrete distribution, it is found that the probability that a randomly selected student earned a C or better is of 0.91.
What does the discrete probability distribution gives?It gives the probability of each grade, as follows:
P(X = A) = 0.43.P(X = B) = 0.31.P(X = C) = 0.17.P(X = D) = 0.05.P(X = E) = 0.04.Hence, the probability of a grade of C or better is given by:
[tex]P(X \geq C) = P(X = A) + P(X = B) + P(X = C) = 0.43 + 0.31 + 0.17 = 0.91[/tex]

You hike 190 meters up a steep hill that has a 33∘ angle of elevation as shown in the diagram.
Answer:
b = 159 m
a = 103 m
angle B is 57 degrees
Step-by-step explanation:
Let’s start with getting the measure of angle B
Mathematically, since we have a right triangle , we have to subtract the given angle from 90 to get the other acute angle
So we have the measure of B as;
90-33 = 57 degrees
To get the value of a, we use the appropriate trigonometric ratio
a faces the angle 33, that makes it an opposite to that angle
190 faces the right angle and that makes it the hypotenuse
Mathematically , the relationship between the two is that trigonometrically, they are related by the sine which is the ratio of the opposite to the hypotenuse
so, we have it that;
sine 33 = a/190
a = 190 * sine 33
a = 103 m
to get b, it is adjacent to the given angle
So with the hypotenuse, the ratio between it and the hypotenuse is the cosine
so;
cos 33 = b/190
b = 190 * cos 33
b = 159 m
Answer:
a = 103 m
b = 159 m
angle B is 57

can u guys please stop giving links fr i need help on this
Answer:
isosceles trapezoid
Step-by-step explanation:
1) find the distance of the points
[tex]\sqrt{(x2-x1)^2 + (y2 -y1)^2}[/tex]
AB = [tex]\sqrt{(4-2)^2 + (7-5)^2} = \sqrt{4 + 4} = \sqrt{8} = 2 \sqrt{2}[/tex]
BC = |7-4| = 3
CD = [tex]\sqrt{(9-7)^2 + (5-7)^2}= \sqrt{4+4} = \sqrt{8} = 2 \sqrt{2}[/tex]
AD = |9-2| = 7
2) equation of the line that passes threw BC
y = 7
3) equation of the line that passes threw AD
y = 5
conclusion
the quadrilateral has two parallel sides and two congruent sides, so it is a isosceles trapezoid
