Answer:
Step-by-step explanation:
A linear equation is not always in the form y = 4.5 − 0.5x,
It can also be like y = 0.2(7 − x)
Or like y + 0.2x = 4.5
Or like y + 0.2x − 4.5 = 0 and more.

Answer:
72
Step-by-step explanation:
(9+9+7^2)-4+9
(9+9+49)-4+9
67-4+9=72
I believe this is correct.
Answer:
(9+9+7^2)-4+9= 72
Step-by-step explanation:
Using PEMDAS, we can solve this problem easily. First, look for parentheses. Inside of the parentheses is an exponent, 7^2. This equals 49. Continuing to solve inside the parentheses, we get 9+9+49= 67. Now, we add and subtract from left to right. Our new equation looks like 67-4+9=?. 67 minus 4 is 63, and 63 plus 9 is 72. Thus, the answer to this equation is 72.

Find the length of side x simplest radical form with a rational denominator
Answer:
The length of x in the simplest radical form with a rational denominator will be:
[tex]x=\frac{5\sqrt{3}}{2}[/tex]Step-by-step explanation:
Given
hypotenuse = 5
angle Ф = 60°
To determine
x = ?
Using the trigonometric ratio
cos Ф = adjacent / hypotenuse
here
Ф = 60°
adjacent of 60° = x
hypotenuse = 5
so substituting Ф = 60°, adjacent = x and hypotenuse = 5 in the equation
cos Ф = adjacent / hypotenuse
so
[tex]cos\:60^{\circ }\:=\:\frac{x}{5}[/tex]
[tex]\frac{\sqrt{3}}{2}=\frac{x}{5}[/tex]
switch sides
[tex]\frac{x}{5}=\frac{\sqrt{3}}{2}[/tex]
Multiply both sides by 5
[tex]\frac{5x}{5}=\frac{5\sqrt{3}}{2}[/tex]
Simplify
[tex]x=\frac{5\sqrt{3}}{2}[/tex]
Therefore, the length of x in the simplest radical form with a rational denominator will be:
[tex]x=\frac{5\sqrt{3}}{2}[/tex]A problem contains the points (0,0),(1,-2) and (-1,-4). What is the equation of this parabola in standard form?
Answer:
The general equation of the parabola y = -3 x² + x
Step-by-step explanation:
Step(i):-
Given points are (0,0) , (1, -2) and ( -1 , -4 )
Given the standard parabola
y = ax²+ b x + c ...(i)
Passing through the point (0,0)
c = 0
Passing through the point (1,-2)
-2 = a(1) +b(1)
a + b = -2 ...(ii)
Passing through the point (-1, -4)
- 4 = a - b
a - b = -4 ...(iii)
Step(ii):-
Adding (ii) and (iii) equations , we get
2 a = -6
a = - 3
substitute a = - 3 in equation (ii)
-3 + b =-2
b = -2 + 3 = 1
Final answer:-
The general equation of the parabola
y = ax²+ b x + c
y = -3 x² + x + 0
y = -3 x² + x

If y − 3 = 3x, which of the following sets represents possible inputs and outputs of the function, represented as ordered pairs?
A. {(0, 3), (1, 6), (2, 9)}
B. {(3, 0), (6, 1), (9, 2)}
C. {(1, 3), (2, 6), (3, 9)}
D. {(3, 1), (6, 2), (9, 3)}
Answer:
A. {(0, 3), (1, 6), (2, 9)}
Step-by-step explanation:
All you have to do is substitute them
A.
y − 3 = 3x
3 - 3 = 3 (0)
0 = 0
y − 3 = 3x
6 - 3 = 3 (1)
3 = 3
y - 3 = 3x
9 - 3 = 3 (2)
6 = 6
__________________________________________________________
B.
y - 3 = 3x
0 - 3 = 3(3)
-3 = 6
You can tell that this one can't be one of the answer which means that B wont be the answer, so you don't have to do anymore work for this one.
__________________________________________________________
C.
y - 3 = 3x
3 - 3 = 3(1)
0 = 3
This one can't be an answer either
__________________________________________________________
D.
y - 3 = 3x
1 - 3 = 3(1)
-2 = 3
And this one can't be an answer either
__________________________________________________________
This concludes, that A will be the answer here since all of the ordered pair can be x and y when you use the inputs and outputs that were given.
Hope this helped!

A scale on a map of a national park reads 1 inch equals 0.25 miles. The national park is roughly in the shape of a rectangle. If the map of the park is 12 inches tall and 8 inches wide, estimate the total area of the park
Answer:
24 miles
Step-by-step explanation:
12 x 8 = 96
1 in = 0.25
96 in = 24
Answer:
6m^2
Step-by-step explanation:
Set up proportions and find the length and width of the park in miles.
Length:
l = 12(0.25)
l = 3 miles
Width:
w = 8(0.25)
w = 2 miles
The area of the park is A = lw = (3)(2) = 6 mi.2

Calculate the mean, median and mode for each set of data.
2, 4, 7, 4, 8, 9, 12, 4, 7, 3
Answer:
mean= 6
median= 5.5
mode= 4
Step-by-step explanation:
mean is all the numbers added up then divided the total amount of numers up then divide. 2+3+4+4+4+7+7+8+9+12=60/10=6
median is the numbers lowest to highest then the middle number
2,3,4,4,4,7,7,8,9,12 the median is 5.5 because that is the middle between 4 and 7
mode is the most frequent value and that is 4 because 4 shows us 3 time and 7 showsup 2

hope it helps :D
am I too late to answer this!?
The given numbers can be rounded off by using the rules of rounding off to the nearest hundredths and rounding off to the nearest thousandths.
Rules for rounding off to the nearest hundredths are:
Rule 1 - In rounding off to the nearest hundred, the digit at tens place is in between 0 to 4 then replace that digit by 0.
Rule 2 - In rounding off to the nearest hundred, the digit at units place is replaced tens place digit by 0 if the digit is greater than or equal to 5 and hundreds place digit is increased by 1.
Rules for rounding off to nearest thousandths:
Rule 1 - In rounding off to nearest thousandths, if the digit at hundreds place is in between 0 to 4 then it is replaced by 0.
Rule 2 - In rounding off to the nearest thousandths, if the digit at hundreds place is greater than or equal to 5 then increase it by 1.
2). The largest decimal in hundredths rounded to 0.5 is 0.49.
3). One centimeter is equivalent to about 0.3937 inches. So, the given equivalent rounding to the nearest hundredths is 0.39.
4). The number 50766.25 rounded to the nearest hundreds is 50766.20 and the number 1522.9875 rounded to the nearest thousandths is 1522.9878.

Step-by-step explanation:
To solve the equation ...
sin(25°) = x/12
multiply by the denominator of the x term.
12·sin(25°) = 12(x/12)
x = 12·sin(25°)

Pls help and show workings
Answer:
x = 30
Step-by-step explanation:
Since RQ bisects ∠ PRS, then
∠ SRQ = ∠ PRQ , substitute values
3x - 20 = x + 40 ( subtract x from both sides )
2x - 20 = 40 ( add 20 to both sides )
2x = 60 ( divide both sides by 2 )
x = 30
Given f(x)=3x−2, find f(−5).

Someone help plz I need some help good at finding slope people? Anyone
Answer:
So the slope is -5/2.
Step-by-step explanation:
You want to look at the line to find the slope of it. For slope you want to find rise/run. This is the same as: change in y/change in x. awe have 2 points (the blue dots) to find slope. With this, let's find the change in y and the change in x. For those 2 dots, the change in y is down 5, which means -5 (if it was up 5 it would be 5)For change in x, it is to the right 2, which means 2 (if it was 2 to the left then it would be -2). Therefore, the slope would be change in y/change in x which is -5/2 (the 3rd option)i need to find the slope from two points!show the work please
