Write an equation for a line parallel to y = − 2 x + 4 and passing through the point ( 2 , 1 )
Answer:
x=2y
Step-by-step explanation:
y=-2x+4 is perpendicular to the line which passes through (2,1). We know that we can use the formula y=mx+c to find the gradient of the line with the equation y=-2x+4, which will give you -2. The product of the gradient of two perpendicular lines is always -1. So the gradient of the line which passes through (2,1 ) is -½.
Now,to find the equation of the line,we use the formula y-y1=m(x–x1)which will give you the answer 2y=x when solved.
Casey burrows 3200 for a computer system at a rate of 4.25% per year. How much simple interest will he owe if he takes 4 months to repay the loan? Round to the nearest cent.
Answer:
$45.33
Step-by-step explanation:
First we find 4.25% of $3200 to find the interest in 1 year.
For simple interest, use this formula:
I = Prt
where
I = amount of interest
P = principal amount (the amount deposited or borrowed)
r = annual interest rate
t = number of years
We have
I = ?
P = $3200
r = 4.45% = 0.425
t = 1 year
I = ($3200)(0.0425)(1)
I = $136
The interest in 1 year is $136.
Now we convert 4 months to years
1 year = 12 months
4/12 = 1/3
4 months are only 1/3 of a year, so he pays only 1/3 of the interest of an entire year.
1/3 * $136 = $136/3 = $45.3333...
Answer: $45.33

The graphs of functions f(x) and g(x) = f(x)+k
The value of k is ____?
Answer:
2
Step-by-step explanation:
f(x) starts at the orgin, (0, 0), and g(x) starts at (0, 2)
With this information we can decide that k is 2 as it moved the line up 2

1/4X - 8 + 12 = -3/4X + 5 Solve for X
Answer:
x = 1
Step-by-step explanation:
I'm going to convert this to decimal to make it easier to type
Since x = 1, there is no need to include it in the equation
1/4 - 8 = -7.75 + 12 = 4.25
-0.75 + 5 = 4.25
Answer:
By simplifying both sides of the equation, then isolating the variable.
X=1
Step-by-step explanation:
1/4*1-8+12=-3/4*1+5

The triangle is an equilateral triangle and all the angles in an equilateral triangle equal 60°.
Straight lines have 180° angles.
180 - 60 = 120
i don't know how to do math lol
Answer:
Ima guess 60
Step-by-step explanation:
9514 1404 393
Answer:
60°
Step-by-step explanation:
The exterior angle is equal to the sum of the remote interior angles:
100° = 40° +∠B
60° = ∠B . . . . . . . . . . . . . subtract 40° from both sides

Answer:

Explanation:
A square root of a number
n
is a number
x
such that
x
2
=
n
Note that if
x
is a Real number then
x
2
≥
0
.
So any square root of
−
49
is not a Real number.
In order to be able to take square roots of negative numbers, we need Complex numbers.
That's where the mysterious number
i
comes into play. This is called the imaginary unit and has the property:
i
2
=
−
1
So
i
is a square root of
−
1
. Note that
−
i
is also a square root of
−
1
, since:
(
−
i
)
2
=
(
−

⋅
i
)
2
=
(
−

)
2
⋅
i
2
=

⋅
(

)
=

Then we find:
(

)
2
=

2
⋅
i

(

)
=

So
7
i
is a square root of
−
49
. Note that
−
7
i
is also a square root of
−
49
.
What do we mean by the square root of
−
49
For positive values of
n
, the square root is usually taken to mean the principal square root
√
n
, which is the positive one.
For negative values of
n
, the square roots are both multiples of
i
, so neither positive nor negative, but we can define:
√
n
=
i
√
−
n
With this definition, the principal square root of
−
49
is:

The question remains: Where does

It is possible to define Complex numbers formally, as pairs of Real numbers with rules for arithmetic like this:
(
a
,
b
)
+
(
c
,
d
)
=
(
a
+
c
,
b
+
d
)
(
a
,
b
)
⋅
(
c
,
d
)
=
(
a
c
−
b
d
,
a
b
+
c
d
)
These rules for addition and multiplication work as expected with commutativity, distributivity, etc.
Then Real numbers are just Complex numbers of the form
(
a
,
0
)
and we find:
(
0
,
1
)
⋅
(
0
,
1
)
=
(
−
1
,
0
)
That is
(
0
,
1
)
is a square root of
(
−
1
,
0
)
Then we can define
i
=
(
0
,
1
)
and:
(
a
,
b
)
=
a
(
1
,
0
)
+
b
(
0
,
1
)
=
a
+
b

A snake bar sold 12 1/2 gallons of milk at 35 cents a pint. How much did the snack bar receive for the milk
9514 1404 393
Answer:
$35.00
Step-by-step explanation:
The number of pints sold is ...
(12.5 gal)×(8 pt/gal) = 100 pt
Then the total amount received for the milk is ...
(100 pt)($0.35/pt) = $35.00
-5 + 9x4-2+(8-3)x6 divide 2 +3
It's a fraction. At the numerator we have : -5+9×4-2+(8-3)×6 = -5 + 36 -2 + 5×6 = -5 +36-2 +30= 31-2+30 = 29+30= 59
59/2 = 29.5 +3 = 32.5
