Answer:
A) 1/2
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(8-3)/(4-(-6))
m=5/(4+6)
m=5/10
m=1/2

A jet ski depreciates at 11% of its original value each year. If the jet ski was $8,000 at its time of purchase, what is the value of the jet ski after 5 years?
Answer: $4467.25
Step-by-step explanation:
Exponential decay problem. 8000(0.89)^5.
100-11 = 89
89/100= 0.89, that is how we got the decimal.
Then, solve.
0.89 * 0.89 * 0.89 * 0.89 * 0.89 = 0.5584059449
0.5584059449 * 8000 = 4467.2475592
Round the decimal part to the nearest hundredth, which is $4467.25.
25 The library has an empty bookcase with 4 shelves. Each shelf can hold 23 chapter þooks. If the library has 117 new chapter books, how many will not fit on the bookcase?.
Answer:
25 chapter books
Step-by-step explanation:
117 - (23×4)
[23×4=92]
.°. 117 - 92 = 25
Step-by-step explanation:
Total Shelf Capacity = Capacity per shelf x Number of Shelves
= 23 x 4
= 92
Number of new books to be fit in = 117
Amount of books Overflow = Number of books to be fit in - Total Shelf Capacity
= 117 - 92

Answer:
If [tex]p(x)[/tex] is divisible by [tex]x-2[/tex], then [tex]m = \frac{1}{2}[/tex].
Step-by-step explanation:
Let [tex]p(x) = 2\cdot x^{2}-(m+3)\cdot x - 1[/tex], if [tex]p(x)[/tex] is divisible by [tex]x-2[/tex], then [tex]p(2) = 0[/tex]. That is:
[tex]2\cdot 2^{2}-(m+3)\cdot (2)-1 = 0[/tex]
[tex]8 - 2\cdot m -6 -1 = 0[/tex]
[tex]1 -2\cdot m = 0[/tex]
[tex]2\cdot m = 1[/tex]
[tex]m = \frac{1}{2}[/tex]
If [tex]p(x)[/tex] is divisible by [tex]x-2[/tex], then [tex]m = \frac{1}{2}[/tex].

What is the solution to the equation 2(x + 3)2 = 98?
Answer: if you're solving by x it would be x=43/2
Step-by-step explanation:
What is the solution of the system of equations below?
y + 2x = 2
y + 4x = 0
F. (1, -4) G. (-1,-4) H. (-1, 4) I. (1, 4)
G
Solution:
Here,
y+2x=2
y=2-2x
Now,
Putting the value of y
y+4x=0
2-2x+4x=0
2+2x=0
2(1+x)=0
1+x=0
x=-1
Then,
Putting the value of x
y=2x-2
=2×-1-2
=-2-2
=-4
Hence,the solution is (-1,-4)

Which of the following statements is true about the ordered pair (-2,3) is TRUE?
1. It is one of many solutions to the system
2. It is not a solution to either equation
3. It is the only solution to the system of equations
4. It is a solution to the first equation but not the second equation
Answer:
(-2, 3) is one of many solutions to the system
Step-by-step explanation:
Let's actually solve the system so that we can compare the result with the given pair (-2, 3):
Multiplying the second equation by -2 results in:
2x + 4y = 8
-2x - 4y = -8
We see that these equations are identical. Thus, there are infinitely many solutions.
1. is true: (-2, 3) is one of many solutions to the system

A wooden building has the shape of a
rectangular pyramid. The building's
base is 100 meters long and 50
meters wide. The height of each
triangular face is 40 meters. How
much wood was used to make the
entire building?
A 33,000 m²
B 13,000 m2
C 11,000 m2
D 6,000 m2
Answer:
B: 13000 m²
Step-by-step explanation:
To find how much wood is used, we will have to find the surface area of the wooden building.
Formula for surface area of a rectangular pyramid is;
SA = lw + l√(h² + w²/4) + w√(h² + l²/4)
We are given;
l = 100 m
w = 50 m
h = 40 m
Thus;
SA = (100 × 50) + 100√(40² + 50²/4) + 50√(40² + 100²/4)
SA = 5000 + 4717 + 3201.56
SA = 12918.56
Approximating to 2 significant figures gives;
SA = 13000 m²

3) m< 5 = 25
4) m<7 = 25
5) 110
6) 30.5
7) 74
Step-by-step explanation:
1)
x + 155 = 180
x = 25
2)
<4 = 155 because of vertical angle thm
3)
<5 = 25 (congruent to <1) b/c of corresponding angles thm

4x = 106
x = 26.5
x+ 4 = 30.5

Answer:
2970
Step-by-step explanation:
I hope it helped :) if it didnt just message me since in confused whats the dot between the 6.3 and 10²
Answer:
2.97*10^3
Step-by-step explanation:
You have to solve it first so you have 2970 as your answer but you want it in scientific notation. To do this put the decimal after the first number this gives you 2.970. Whenever you need to make the number bigger you use a positive power and whenever you want to make a number smaller you use a negative power. The amount of powers the 10 gets is the amount of times you move it over. You have 2.970 and to get to the original number you need to move it 3 places to the right. Going to the right with your decimal makes it bigger which what you want, so you have 2.970*10^3 as your answer.

Which quantity makes the equation true?
x + 3x + _______ = 7x
Answer:
Step-by-step explanation:
C) 3X
Answer: C. 3x
Step-by-step explanation:
Since x and 3x both have x, you can add them together to get 4x (if there is x by itself, it really means that there is one of it, so it would be 1x.)
Then, you subtract 7x by 4x, which gives you the answer, 3x. You could also solving it by asking yourself: What number plus 4x equals 7x, which would give you 3x.
