Answer:
A dryer costs $450.
A washer costs $509.
Step-by-step explanation:
Let:
"washer" = x
"dryer" = y
Set the equations:
x + y = 959
x = y + 59
First, plug in y + 59 for x in the first equation for x:
x + y = 959
(y + 59) + y = 959
Simplify, combine like terms:
y + y + 59 = 959
2y + 59 = 959
Next, isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. PEMDAS is the order of operations, and stands for:
Parenthesis, Exponents (& Roots), Multiplications, Divisions, Additions, Subtractions.
First, subtract 59 from both sides of the equation:
2y + 59 (-59) = 959 (-59)
2y = 959 - 59
2y = 900
Next, divide 2 from both sides of the equation:
(2y)/2 = (900)/2
y = 900/2
y = 450
Next, plug in 450 for y in one of the equations:
x = y + 59
x = (450) + 59
x = 509
Check:
x + y = 959
450 + 509 = 959
959 = 959 (True).

Answer:
$450
Step-by-step explanation:
1. First, let's make a system of equations:
[tex]y+59=x,x+y=959[/tex] (y = dryer, x = washer)2. (Solving)
Solve y + 59 = x for y:
[tex]y + 59 = x[/tex] [tex]y + 59-59=x-59[/tex] (Subtract 59 from both sides)[tex]y = x-59[/tex]Substitute x - 59 for y in x + y = 959
[tex]x + y = 959[/tex] [tex]x+x-59=959[/tex] [tex]2x - 59 = 959[/tex] [tex]2x - 59 + 59 = 959 + 59[/tex] (Add 59 to both sides)[tex]2x = 1018[/tex] [tex]\frac{2x}{2} = \frac{1018}{2}[/tex] (divide both sides by 2)[tex]x = 509[/tex]Substitute 509 for x in y = x - 59
[tex]y = x - 59[/tex] [tex]y = 509-59[/tex] [tex]y = 450[/tex]Therefore, the dryer costs $450. (The washer costs $509).

When graphing data from a study the scale of the data:
A, may make the data misleading
B, should always be presented using a factor of 2.
C, is not important.
D, will not change how the data appears.
Answer:
B
Step-by-step explanation:
B no steps needed to do this
The scale factor enlarges or reduces the graph of the data set thus it will not change the shape thus option (D) is correct.
What is a graph?A graph is a diametrical representation of any function between the dependent and independent variables.
The graph is easy to understand the behavior of the graph.
The scale factor is used to enlarge any data set by the same multiplier.
For example, a coordinate (x,y) will be enlarged by (9x,9y) so 9 will be the scale factor.
The scale factor is useful to work with data which not lie in the range of the given axis in coordinate geometry.
When we apply the scale factor it will either enlarge or reduce the plot size but the shape will remain the same so the data representation will be the same.
Hence "The scale factor enlarges or reduces the graph of the data set thus it will not change the shape".

Find the distance between R (3, 4) and T (7, 2).
Answer:
[tex]\sqrt{20}[/tex] or 4.47
Step-by-step explanation:
To find the distance between two points on a plane, you can use the distance formula: [tex]d=\sqrt{(y^{2}-y^{1})^2 + (x^{2}-x^{1})^2 }[/tex]
Plug your values in to get the distance between the two points.
[tex]d=\sqrt{(y^{2}-y^{1})^2 + (x^{2}-x^{1})^2 }[/tex]

What is the slope of the line in the xy plane that passes through the points {-5/2 ,1} and {-1/2, 4}?
Answer:
m=3/2
Step-by-step explanation:
the line: y=mx+b
This line passes through the points
-> These points (x,y) are on the line
(-5/2,1) : x=-5/2 y=1
1=-5/2m+b
(-1/2,4) : x=-1/2 y=4
4=-1/2m+b
We have a system of equation:
1=-5/2m+b
4=-1/2m+b
After solving this, we have m=3/2 b=19/4
