How do you graph y=1/2x -2
Answers
Answer:
Graphing y=1/2x-2 will look like this on the graph
Answer:
Step-by-step explanation:
the 1/2 is a gradient so you go up 1 for every 2 to the right
the -2 is the Y intercept so you start graphing the gradient from -2 on the Y axis

because 5 less than 35 is 30 and 5 less than 10 is 5. it would only make sense for 5 less than 110 is 105
7. D. 54
every other number in the equation is one less (8,7,6,5)
and inbetween those the number is multiplied by 3 (2×3=6, 6×3=18) so then 18×3 =54
the middle left. D. 27
every other one is multiplied by 2 (2×2=4, 4×2=8, 8×2=16) but the first one is multiplied by 3. (1×3=3 3×3=9 9×3=27 27×3=81)
11. A.11
it adds 6 every other (17+6=23, 23+6=29)
for every other first one it adds 4. (7+4=11, 11+4=15, 15+4=19)
12. D. 18
for every other it adds 2.(4+2=6, 6+2=8)
for every other second it adds 6. (6+6=12, 12+6=18, 18+6=24)
15. D. 49
for every other it subtracts 6 (67-6=61, 61-6=55, 55-6=49)
the every other second it divides in half. (32÷2=16, 16÷2=8, 8÷2=4)
18. D. 17
for every other it adds 2.(13+2=15, 15+2=17, 17+2=19)

Find 2 points that are 3 units from Point C and also share the same y-coordinate as Point C.

I'm guessing point C is (-6,-5)? But then, it would have to be the coordinates you listed, (-3,-5) and (-9,-5) because nothing else makes sense.

How do you decide in what way to reorder the terms of expression when simplifying it
Answers
We use the PEMDAS to reorder the terms of expression when simplifying it.
What is an expression?One mathematical expression makes up a term. It might be a single variable (a letter), a single number (positive or negative), or a number of variables multiplied but never added or subtracted. Variables in certain words have a number in front of them. A coefficient is the number used before a phrase.
We use the PEMDAS to reorder the terms of expression when simplifying it.
The abbreviation PEMDAS is used to indicate the sequence of steps to be taken when resolving expressions with multiple operations. P is for "parentheses," E is for "exponents," M is for "multiplication," D is for division, A is for addition, and S is for subtraction.
Therefore, use PEMDAS to simplify any expression.

Answer:
OTHER GUY IS WRONG!!!
Given that,
Each statement describes a transformation of the graph of f(x) = x.
We have to determine,
Which statement correctly describes the graph of g(x) if g(x) = -8f(x)?
According to the question,
Let, The graph f(x) = x,
Where r is the real number which is r >0.
And The graph of g(x) if g(x) = -8f(x),
The value of the r is -8.
The graph which describes the transformation of the given graph in the steps follows all the steps given below.
The function g(x) = 8f(x) reflects stretched the graph of f(x) vertically by a factor of r.The function g(x) = -8f(x) reflects the graph of f(x) about the x-axis and stretched the graph of f(x) vertically by a factor of r.The graph of g(x) = f(8x) shrink the graph of f(x) horizontally by a factor of r.The function g(x) = f(-8x) shrink the graph of f(x) about the y-axis and shrink the graph of f(x) horizontally by a factor of r.Hence, The graph of f(x) reflected about the x-axis and stretched vertically by a factor of 8.

The length of a rectangle is (5x − 1) cm and the width is (11 − 2x) cm. If the perimeter of the rectangle is 44 centimeters, what is the area of the rectangle?
Answers
Answer:
57 cm²
Step-by-step explanation
l = length
w = width
p = perimeter
(5x - 1) = length
(11 - 2x) = width
44 = perimeter
Formula for the perimeter of a rectangle:
l + l + w + w
2l + 2w = p
Substitute the variables for the length and width with the values given to you by the problem, then solve.
2(5x - 1) + 2(11 - 2x) = 44
(10x - 2) + (22 - 4x) = 44 (Distributive property)
6x + 20 = 44
6x = 24
x = 4
Plug x = 4 back into the length and width.
Length = (5x - 1), (5(4) - 1), (19)
Width = (11 - 2x), (11 - 2(4)), (3)
Area for a rectangle: Length × Width = Area.
19 × 3 = 57 cm²
This is all in cm so answer with cm²

Rita just bought a car for 15,000. She paid 20% down and borrowed the remainder at an annual interest rate of 9.0%. The loan will be repaid over four years with monthly payments of $298.62. How much is rita's down payment and how much did she borrow?
Answers
Answer:
Rita's down payment is $3000 and she borrowed $12000.
Step-by-step explanation:
The cost of the car is $15000.
Given that she paid 20% down and borrowed the remainder.
So, Rita's down payment= 20% of $15000
[tex]=\frac{20}{100}\times 15000[/tex]
= $3000
As she borrowed the remainder cost, so,
the borrowed amount = 15000-3000
= $12000
Hence, Rita's down payment is $3000 and she borrowed $12000.

If n divided by m equals 7/8,
what does m divided by n equal?
Answers
Step-by-step explanation:
1,
It is found that m divided by n is equal to 8/7.
How can we interpret the division?When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get.
Thus, if 10 mangoes are there, and 2 people, then 10 ÷ 2 is the number of mangoes each person would get, which is 5.
Division, thus, can be interpreted as equally dividing the number that is being divided in total x parts, where x is the number of parts the given number is divided.
Thus, a/ b = a divided in b equal parts.
If n divided by m equals 7/8, then m divided by n equal.
n / m = 7/8
Then m/n = 8/7
Therefore, m divided by n is equal to 8/7.

Answer:
A rate of 5/2 means that:
If we move 2 units to the right, we move 5 units up.
Let's see all the graphs, the easier way to know this is:
In any point of the line, move to the right 2 units.
Then from that point, move up until you meet again with the line, if you moved 5 units, then the slope is 5/2.
A) The slope is 5/2.
B) The slope is 4/2
C) the slope is 5/2
I can not see very well graphs E and D in the image.
E) may have a slope of 5/2, you should measure it.
D has not a slope of 5/2, you can compare it with A and see that is totally different, so you can discard option D.
Lines A and C are having a slope of (5/2) and line E may have the slope of (5/2).
Step-by-step explanation:
Given information:
Line A,B,C,D and E having different slopes;
Now as we know that equation of the line is:
[tex]y=mx+c[/tex]
where, m is the slope of the line
Now, Also [tex]dy/dx=m[/tex]
Hence, the slope of the line can also be calculated according to that.
Now, as given in the graph:
Line A is having [tex]dy=10\; \text {and} \; dx =4[/tex]
Hence slope of line A
[tex]dy/dx(A)=5/2[/tex]
Similarly:
Line B is having slope of (4/2)
Line C is having slope of (5/2)
Line D is not having slope of (5/2)
And Line E may have the slope of (5/2).

Brayden just lit a new candle and then let it burn all the way down to nothing. The
candle burned at a rate of 0.75 inches per hour and its initial length was 6 inches.
Write an equation for L, in terms of t, representing the length of the candle
remaining unburned, in inches, t hours after the candle was lit.
Answers
Answer:
L = -0.75t + 6
Step-by-step explanation:
L = length (this is what equation you are looking to solve for
-0.75t because the candle burns at 0.75 in per hour so the value decreases, hence the (-)
+6 because the candle has a positive value of 6 inches to begin with
The standard form of what you are writing is called slope intercept form y = mx + b, learn it because it is very important for future math.
The equation of the candle remaining unburned at any given time is L(t) = 6 - 0.75t.
What is a function ?A function is a set of values of the dependent variable for specified independent variable.
According to the given question Brayden just lit a new candle and then let it burn all the way down to nothing.
The candle burned at a rate of 0.75 inches per hour and its initial length was 6 inches we have to write an equation for L in terms of t where t represents time in hours and L(t) represents length of the candle remain unburned.
∴ L(t) = 6 - 0.75t.
At t = 0 the length of the unburned candle L(t) will be 6 inches and at t = 8 L(t) will be 0,So the candle can burn for 8 hours.
