Answer:
Parallel lines 1
perpendicular lines -1
Step-by-step explanation:
2x-2y = -6
Solve for y to get it in slope intercept form
-2y = -2x-6
Divide by -2
y = x+3
This is slope intercept form y = mx+b where m is the slope
Parallel lines have the same slope
A parallel line would have a slope of 1
Perpendicular lines would have a slope that is a negative reciprocal
-1/1
Perpendicular lines would have a slope of -1
Let us first put it into slope-intercept form ⇒ [tex]y = mx + b[/tex]
m: slopeb: y-intercept of the functionTo put it into that format, we need to simply put y on one side of the equation and the rest on the other side
[tex]2x - 2y =-6\\-2y = -2x -6\\y = x +3[/tex]
What do we want to find first ⇒ a line parallel to the original line
a line that is parallel to the original line only has one requirement, it must have the same slope, such as the one below[tex]y = x +5[/tex]
What do we also want to find ⇒ a line perpendicular to the original line
a line that is perpendicular to the original line only has one requirement, the slope has to be the negative reciprocal of the original slope⇒ original slope is 1 ⇒ negative reciprocal is - 1/1 = -1
⇒ so an example is
[tex]y = -x + 3[/tex]
Answer:
Line that is parallel: slope is 1Line that is perpendicular: slope is -1Hope that helps!

What is the slope and y-Intercept of the equation on the graph?
Answer:
Slope: 3/2
Y-Intercept: 3
Step-by-step explanation:
The y-intercept is very easy to discover as it is just the Y coordinate when X is zero or "intercepts" the x axis. So if you look directly above the origin you see that the line has the point (0, 3).
The Y Intercept is 3
The slope is found using the slope formula of y2-y1/x2-x1
Lets take two points from the line. We have the (0, 3) point that I mentioned earlier and we can get the x-intercept of (-2, 0)
Lets Solve!
3- 0 = 3
0-(-2) = 2
3/2 is the slope
So the formula is Y = 3/2 + 3
Virgil opened an account with a deposit of $815.
. The bank pays 5% interest compounded annually on this account.
• Virgil makes no additional deposits or withdrawals.
How much interest will the account have earned after 6.5 years?
Answer:
$304.15
Step-by-step explanation:
The amount of interest earned can be found from the formula ...
I = P((1 +r)^t -1)
I = $815((1 +0.05)^6.5 -1) ≈ $815(0.373189) ≈ $304.15
Virgil's account will have earned about $304.15 in interest in 6.5 years.

Find the volume of the cone.
Use 3.14 for π. Round your answer to the nearest tenth if needed. Do not enter units.
Answer:
94.2 cm³
Step-by-step explanation:
Volume of cone= ⅓πr²h
Let's identify the radius of the base and the height of the cone!
r= 3 cm
h= 10 cm
Next, substitute r= 3 and h= 10 into the volume of cone formula.
Volume of cone
= ⅓(3.14)(3²)(10)
= 94.2 cm³

Answer:
There are most likely a few outliers, with the rest of the data close to the mean. The standard deviation is an indication of how "wide" the peak of the graph is. Since we have a very large range, that means that the values cover a very large range. But since the standard deviation is small, that means that most of the values are extremely close to the average (or mean) of the values. With that in mind, let's look at the options and see what fits. The distribution is very flat with a gradual increase in frequency as the numbers approach the mean. * This would have a rather large standard deviation since most of the values would be a fair distance from the mean. So this is a bad choice. There are most likely a few outliers, with the rest of the data close to the mean. * This is a very accurate description of the situation. So it's the correct choice. You can't really know anything about the distribution's shape without actually seeing it, or having more data. * This is a cop out and quite wrong. Therefore this is a bad choice. The distribution is essentially normal or bell shaped. * This is what is usually expected, but since we have a small standard deviation, the curve is more definitely NOT bell shaped. So this is a wrong choice...

Two angles of a quadrilateral measure 125° and 35°. The other two angles are in a ratio of 3:5. What are the measures of those two angles?
Answer:
120° and 80°
Step-by-step explanation:
quadrilateral = 360°
125° + 35° = 160°
360° - 160° = 200°
3/5 of 200° = 120°
200° - 120° = 80°
Answer:
Step-by-step explanation:
Finding the missing angles of quadrilateral:
Ratio of other two angles = 3 : 5
Other two angles are 3x , 5x
Sum of all angles of quadrilateral = 360
125 + 35 + 3x + 5x = 360
Combine like terms
160 + 8x = 360
Subtract 160 from both sides
8x = 360 - 160
8x = 200
Divide both sides by 8 to isolate x
x = 200/8
x = 25
5x = 5*25 = 125
3x = 3*25 = 75
The other two angles are 125° , 75°
A mute for a brass instrument is formed by taking a solid cone with a radius of 10 centimeters and an altitude of 20 centimeters and cutting off the top. The cut is made along a plane that is perpendicular to the altitude of the cone and intersects the altitude 6 centimeters from the vertex. Round your answers to the nearest hundredth.
What is the surface area of the original cone?
What is the surface area of the cone that is removed?
What is the surface area of the mute?
By using the formula for the area of a cone, we will get:
i) 942 cm^2ii) 84.78cm^2iii) 885.48cm^2How to get the surface areas?
First, let's find the area of the original cone. Remember that for a cone of radius R and height H, the surface area is:
A = pi*R^2 + pi*R*H
Then for the original cone where:
R = 10cm
H = 20cm
The area is:
A = 3.14*(10cm)^2 + 3.14*10cm*20cm = 942 cm^2
Now, we remove a smaller cone at 6 cm from the vertex, so we are removing a cone with height of 6 cm, and the radius of this cone is given by:
R' = R*(H'/H) = 10cm*(6cm/20cm) = 3cm
So the area of the removed cone is:
A' = 3.14*( (3cm)^2 + 3cm*6cm) = 84.78cm^2
The final area of the mute will be equal to the difference between the area of the original cone and the area of the removed cone, plus the area of the top cross-section (a circle of radius of 3cm)
A'' = 942 cm^2 - 84.78cm^2 + 3.14*(3cm)^2 = 885.48cm^2
