Answer:
6 + (-15)
Step-by-step explanation:
6 - 15 would also be written as 6 + (-15). If you distribute the '+' into the '-15', you would get the negative 15.
1 * -15 = -15
So, 6 + (-15) would be the equivalent addition expression.

Answer:
k=4
Step-by-step explanation:
euqation of the graph
(1) g(x)= x+3
We have
(2) g(x)=f(x)+k
(3) g(x)=x-1+k
(1) =(3)
x+3 =x -1 + k
-x -x
3= -1+k
k= 4

Explain why points and lines may be coplaner even when the plane containing them is not drawn. Give Examples.
Answer:
The reason why points and lines my be co-planer even when the plane containing them is not drawn is because the by their definition two lines or a line and a point or three points which are fixed in space always have have a direction of view from which they appear as a single line, or for the three points, appear to be on a single line.
This can be demonstrated by the shape of a cross which is always planner
Examples include
1) Straight lines drawn across both side of the pages of an open book to meet at the center pf the book can always be made planner by the orientation#
2) This can be also demonstrated by the plane of the two lines in the shape of a cross which is always planner regardless of the orientation of the cross
3) The dimension that can be defined by three points alone is that of a planner (2-dimensional) triangle shape

The perimeter of the square kitchen floor measures 48 feet. What is the area of the kitchen floor?
32 feet
96 square feet
144 square feet
144 cubic feet
Answer:
144 square feet
Step-by-step explanation:
a square has 4 equal sides + perimeter is the addition of n sides in an n sided shape. 48/4 = 12 so there is 12 feet per side. Area is length times height so 12 x 12 or 144. Two terms multiplied create a square feet so answer is c

PLEASE HELP !! Which of the following is the midpoint of a line segment with endpoints (-2,-4) and (6,8)? (4,6) or (4,4) or (2,2) or (2,4)
Answer:
The answer is (2 , 2)Step-by-step explanation:
The midpoint M of a line segment with two endpoints can be found using the formula
[tex]M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )[/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question
The endpoints are (-2,-4) and (6,8)
The midpoint is
[tex]M = ( \frac{ - 2 + 6}{2} , \frac{ - 4 +8 }{2} ) \\ = ( \frac{4}{2} , \frac{ 4 }{2} )[/tex]
We have the final answer as
M = ( 2 , 2)Hope this helps you
i need some help, with my algebra
Answer:
Hey there!
Perimeter: 24
Area: 24
36+64=x^2
x=10
Perimeter: 10+6+8=24
Area: 1/2bh, 1/2(48)=24
Both the area and perimeter are 24.
Hope this helps :)
Answer:
P=24
A=24
Step-by-step explanation:
To get the perimeter and area of this figure, first we would have to get the value of c using the Pythagorean theorem.
a^2+b^2=c^2
(6)^2+(8)^2=c^2
36+64=c^2
100=c^2
10=c
Perimeter= a+b+c
P=6+8+10
P=14+10
P=24
A=1/2*b*h
A=1/2*6*8
A=3*8
A=24
Hope this helps ;) ❤❤❤
Simba Travel Agency arranges trips for climbing Mount Kilimanjaro. For each trip, they charge an initial fee of $100 in addition to a constant fee for each vertical meter climbed. For instance, the price for climbing to the Shira Volcanic Cone, which is 3000 meters above the base of the mountain, is $400. Let F represent the fee (in dollars) of a trip where they climbed d vertical meters. Complete the equation for the relationship between the fee and vertical distance. F=
Answer:
F = 100 + 0.1d
Step-by-step explanation:
Initial charge is $100Price for climbing 3000 m = 400Then equation to find a fee per vertical distance:
100+3000x = 4003000x = 300x = 300/3000x = $0.1 per/mSo the fee for climbing vertical distance is $0.1 per meter.
Vertical distance = d mTotal cost = FThen, required equation is:
F = 100 + 0.1dSolve the following addition problem 8.08 + 2.78
Answer:
its 10.86
Step-by-step explanation:
add the whole numbers, the add the decimals

This has to be converted into an algebraic expression.
Please help!
Need help on this one
Answer:
3
Step-by-step explanation:
To simplify this expression, we will simply work with the numerator, then the denominator, and then the fraction as a whole, following PEMDAS.
Numerator: 12 - 6 + 5 * (-3)^2
= 12 - 6 + 5 * (9)
= 12 - 6 + 45
= 6 + 45
= 51
Denominator: 17
So our simplified fraction is as follows:
51/17
Which can be reduced to the whole number, 3.
Cheers.

______________please help asap! i need to find the missing coordinate
Answer:
8 or 32
Step-by-step explanation:
So we are given two coordinates and the length of the segment formed by those coordinates.
To find the unknown coordinate, we can use the distance formula. Let the unknown value be n:
Let's let (-2,n) be x₁ and y₁ and let (-7,20) be x₂ and y₂.
The distance formula is given by the formula:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Substitute (-2,n) for x₁ and y₁ and (-7,20) for x₂ and y₂. Also, since we already know that the length is 13, substitute it for d. Thus:
[tex](13)=\sqrt{((-7)-(-2))^2+((20)-(n))^2}[/tex]
Do the operations within the parentheses:
[tex]13=\sqrt{(-7+2)^2+(20-n)^2}\\13=\sqrt{(-5)^2+(20-n)^2}[/tex]
Now, square both sides to take out the square root:
[tex](13)^2=(\sqrt{(-5)^2+(20-n)^2})^2[/tex]
Simplify:
[tex]169=(-5)^2+(20-n)^2[/tex]
Square (-5):
[tex]169=25+(20-n)^2[/tex]
Subtract 25 from both sides. The right cancels:
[tex](169)-25=(25+(20-n)^2)-25\\144=(20-n)^2[/tex]
Now, take the square root of both sides.
[tex]\pm\sqrt{144}=\sqrt{(20-n)^2}[/tex]
Simplify:
[tex]\pm12=(20-n)[/tex]
So, we have two solutions:
[tex](12=20-n)\text { or }(-12=20-n)[/tex]
On the left, subtract 20. On the right, also subtract 20:
[tex](-8=-n)\text { or }(-32=-n)[/tex]
Divide both sides by -1:
[tex](n=8)\text{ or } (n=32)[/tex]
So, our two possible answers are 8 or 32.
Solve for x. -6x+1=-41

Move 7 to right hand side and change it's sign
[tex] \dashrightarrow \sf{ - 6x = - 41 - 1}[/tex]
Calculate
[tex] \dashrightarrow{\sf{ - 6x = - 42}}[/tex]
Divide both sides by -6

Li uses 8.4 grams of sugar every day in her tea. Sue uses 12.6 grams of sugar every day in her coffee. If Li’s sugar canister contains 128 grams of sugar and Sue’s canister contains 191 grams, in how many days will Li and Sue have the same amount of sugar in their canisters?
Answer:
15 days
Step-by-step explanation:
a) Li uses = 8.4 grams of sugar every day in her tea.
Li’s sugar canister contains = 128 grams of sugar
Let x be the number of days at which Li uses sugar in her tea
The Equation for Li's sugar usuage =
y = 128 - 8.4x ......... Equation 1
Where y , the quantity of sugar left.
b) Sue uses = 12.6 grams of sugar every day in her coffee.
Sue’s canister contains = 191 grams
Let x be the number of days at which Sue uses sugar in her tea
The Equation for Sue's sugar usuage =
y = 191 - 12.6x .........Equation 2
Where y , the quantity of sugar left.
We are asked in the question, how many days will Li and Sue have the same amount of sugar in their canisters
We would equate both equations to each other.
Equation 1 = Equation 2
y = 128 - 8.4x = y = 191 - 12.6x
128 - 8.4x = 191 - 12.6x
-8.4x + 12.6x = 191 - 128
4.2x = 63
x = 63/4.2
x = 15
15 days
Therefore Li and Sue have the same amount of sugar in their canisters after 15 days.
To confirm
Equation 1 = Equation 2
y = 128 - 8.4x = y = 196 - 12.6 × 15
y = 128 - 8.4 × 15 = y = 196 - 12.6 × 15
y = 128 - 126 = y = 196 - 189
y = 2 = y = 2

I need ans for Q2, 5 and 7. QUICK PLEASE!!!
−2 = −(n − 8) with step by step please
Answer:
n = 10
Step-by-step explanation:
Order of Operations: BPEMDAS
Step 1: Write out equation
-2 = -(n - 8)
Step 2: Parenthesis (distribute)
-2 = -n + 8
Step 3: Subtract 8 on both sides
-10 = -n
Step 4: Divide both sides by -1
10 = n
Step 5: Rewrite
n = 10
Answer:
[tex]n=10[/tex]
Step-by-step explanation:
So we have the equation:
[tex]-2=-(n-8)[/tex]
First, divide both sides by -1. The left will become positive, and the negative in front of the parentheses will be canceled:
[tex](-2)/-1=(-(n-8))/-1\\2=n-8[/tex]
Add 8 to both sides. The right cancels:
[tex]2+8=(n-8)+8\\n=10[/tex]
So, the value of n is 10.
And we're done!
