Answer:
y + 4 = -3(x - 2)
Step-by-step explanation:
Perpendicular lines have opposite reciprocal slopes. Since the slope of the given line is 1/3, a perpendicular line would have a slope of -3. We know that the line goes through the point (2 , -4), so we can use point-slope form to write an equation.
Point slope: [tex]y-y_{1} =m(x-x_{1})[/tex]
y + 4 = -3(x - 2)
If necessary, this can be written in slope-intercept form as well. In this case, you'd solve for y.
Round 94584 to the nearest hundreds
Answer:
94600
Step-by-step explanation:
A hundred has 2 zeroes. To round a number to the nearest hundreds, just look at the last 2 digits (84). If it is 5 or bigger, add 1 digit (as I did in this exercise) and so it becomes 94600.

How many solutions does 4x + 5 = 6(x + 3) - 20 - 2x have? Show your work.
Answer:
X∈∅
Step-by-step explanation:
4x + 5 = 6(x + 3) - 20 - 2x
distribute the 6
4x+5=6x+18-20-2x
collect like terms
4x+5=4x+18-20
4x+5=4x-2
cancel equal terms
5=-2
statment is false for any value of x

Which regular polygon would have each of its interior angles measure 120°?
nonagon
hexagon
octagon
heptagon
Answer:
Hexagon
Step-by-step explanation:
If in a regular polygon, each interior angle = 120 deg, then each exterior angle = 180–120 = 60 deg. So the polygon has 360 deg/60 deg = 6 sides. The figure is a regular hexagon.

22 + 15 = d - 17
Answer:
d=54
Step-by-step explanation:
22 + 15 = d - 17
37=d-17
54=d
d=54
Answer:
d=44
Step-by-step explanation:
22+15=37 so ?-17=37 well its 44 because 44-17=37
what is the height from the base of the statue to the tortch in inches
Answer: OK so I think Her Size (In a case like this it's ok to ask her size without getting in any trouble.): Her total overall height from the base of the pedestal foundation to the tip of the torch is 305 feet, 6 inches. Height of the Statue from her heel to the top of her head is 111 feet, 6 inches.
Step-by-step explanation:
This should be a simple problem, I think, simple calculate changing the feet to inches or yards, as the problem demands. I believe the height would be 1,813 inches (12 inches per foot), and the thickness of the arm would be 4 yards (3 feet per yard).
Find the value of x so that the ratios are equivalent. 9:x and 54:8

How to obtain real measurements from the ratio of two measurements?Suppose the real measurements were "a" and "b"
Then their ratio will be formed as
[tex]\dfrac{a}{b} = \dfrac{p \times x}{q \times x} = \dfrac{p}{q}[/tex]
where is a common factor (not 1)
Which shows that to get the real measurements from the given ratio, we need to assume to have some factor possibly cancelled from both the numerator and the denominator.
Thus, a = px, b = qx
Therefore, the value of x so that the ratios are equivalent.
9:x and 54:8
x= 48
or 9:48
Hence, the value of x so that the ratios are equivalent is 48.

y = 4x - 6
y = 4x + 10
What is the solution to the system?
Answer:
No Solution
Step-by-step explanation:
y = 4x - 6
y = 4x + 10
You can set them equal to each other because they both are y.
4x-6=4x+10
-6=10

9. What is the sales tax on an item that costs $67.00 if the state sales tax is 6.5%?
A. $435
B. $4.35
C. $3.35
D. $.45
Answer:
B
Step-by-step explanation:
Answer:
B. $4.35
Step-by-step explanation:
to find your sales tax you just have to do [cost of the item] x [ percentage as a decimal]= sales tax
so in your case it would be [$67.00] x [0.065] = $4.35
im new can anyone help
Answer:
We have the equation:
[tex]W = W_0*(\frac{1}{2})^{0.36*t}[/tex]
Where:
W₀ is the initial area of the wound, and t is the time in days.
Now, if we initially have a wound of 25 mm^2, then:
W₀ = 25mm^2
And we can replace it in the equation, then we get:
[tex]W = (25mm^2)*(\frac{1}{2})^{0.36*t}[/tex]
We want to know the size of this wound after:
a) 1 day.
We know that t represents time in days, so here we just need to replace t by one, then:
[tex]W = (25mm^2)*(\frac{1}{2})^{0.36*1} = 19.5 mm^2[/tex]
b) 1 week
Again, t represents the time in days, so we need to write this in days.
We know that:
1 week = 7 days.
then t = 7
The size of the wound after 7 days is:
[tex]W = (25mm^2)*(\frac{1}{2})^{0.36*7} = 4.36 mm^2[/tex]

April and Bill went to the grocery store to buy chocolate bars. April bought 4 small chocolate bars and 6 large chocolate bars , while Bill bought 4 small chocolate bars and 3 large chocolate bars. If April paid $16.50 and Bill paid $11.25, what is the price of a single large chocolate bar?
Step-by-step explanation:
To do this equation, we could put it in terms of algebra, lets say the large chocolate bars are represented by L and the small bars by S
April
4S + 6L = $16.50
Bill
4S + 3L = $11.25
Looking at this, we can see that the difference between the two purchases is that Bill bought three less large chocolate bars, this means the difference in total cost equals three large chocolate bars. Using this knowledge.
$16.50 minus $11.25 = $5.25
$5.25 = Three Large Bars
Divide this by three to get the cost of one large bar.
$1.75 is the cost of one single large bar.
Answer:
April: 4x+6y=16.5
Bill: 4x+3y=11.25
solving the two equations simultaneously will give you y=1.75
Compare and contrast the formulas for the volume of a pyramid and the volume of a cone.
Because a pyramid has a non-circular base, the volume is always described in square units, but the volume of a cone is stated in cubic units.
Because a pyramid has a non-circular base, the volume is always described in cubic units, but the volume of a cone is stated in square units.
Both formulas are 13Bh, but the base of a pyramid is always a square.
Both formulas are 13Bh, but the base of a cone is always a circle.
FIRST CORRECT ANSWER GETS BRAINLIEST! CALCULATE THE SLOPE FOR INTERVAL A.
Answer:
60
Step-by-step explanation:
The slope is going to be rise over run which is feet/seconds
from (0,0) to (600,10) which is a the line rises up 600 feet and runs 10 seconds
so it is just 600/10 which is 60

Which of the following could be the graph of the line y = 3x - 2?
You didn't give a graph but I will visualize what it looks like for you.
The line is going through (0,-2) because that is the y-intercept.
The line has a slope of 3.
So, the line goes through:
(1,1)
(2,4)
(3,7)
(4,10)
(5,13)
Since there is no picture provided, I can't give you the answer, but I can help you solve it.
To solve this you have to first look at the b part of the formula y=mx+b, so -2.
Then, you can find -2 on the y-axis (the vertical axis)
and then you could move upwards 3 spaces, then right 1 space.
You would do this as the slope is 3/1 (the mx part of the equation).
Finally, you continue to move up 3, and right 1 until there are enough points on the graph to make a line, and that will help you see what graph is correct.
