What is the equation of a line that has a slope of 2 and passes through point (-6, 3)?
Step-by-step explanation:
m= 2
x1 = -6
y1 = 3
Applying the formula,
y-y1 = m(x-x1);
we have,
y - 3 = 2(x -(-6))
y- 3 = 2(x + 6)
y - 3 = 2x + 12
y -2x -3 -12 = 0
y -2x -15 = 0
Therefore the equation of the line is;
2x - y + 15 = 0

Find the variance of: 2 4 5 6 7 9 10
Answer:
s = 7.811 ¯ 6
Step-by-step explanation:
x = 2 + 4 + 5 + 6 + 7 + 9 + 10 /7
¯ x = 43 /7
s = ( 2 − 6.1 ) 2 + ( 4 − 6.1 ) 2 + ( 5 − 6.1 ) 2 + ( 6 − 6.1 ) 2 + (7 − 6.1 ) 2 + ( 9 − 6.1 ) 2 + ( 10 − 6.1 ) 2/ 7 − 1
s = 7.811 ¯ 611. Health. Sherri is considering joining a health club. To be a member of Roman's Gym, she would

It would take 11 months of membership for the total money paid to each club to be the same.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
A variable can either be dependent or independent. A dependent variable depend on other variable while an independent variable does not depend on other variables.
Let x represent the number of months subscribed. Hence,
For Roman's gym:
Total payment = 25x + 49.99
For Athens Fitness:
Total payment = 18x + 126.99
For both clubs to have the same payment:
25x + 49.99 = 18x + 126.99
7x = 77
x = 11
It would take 11 months of membership for the total money paid to each club to be the same.

1. How do you dilate a figure on the coordinate plane and determine its scale factor?
2. How do you determine if polygons are similar?
3. Explain one way can you determine if two triangles are similar, without knowing all the angle
or side measurements.?
Answer:
1. You can look at side measurements. Angle measurements will not change so do not use them as reference. For example, if a rectangle has one side as 7 and the other 3, then the scale factor of a rectangle with a side of 21 and 9 would be 3, because 21÷7 is 3 or 9÷3 is 3.
2. You can determine a polygon is similar by having the same angles and/or similar sides.
3. All you need is one side and one angle if the angle and side are opposit each other, so a and A or b and B or c and C. If this is not represented in a problem then you can use 2 angles and 1 side or 1 angle and 2 sides to figure out if they are similar.

Answer:
The original length of the new candle is 10 inches
Step-by-step explanation:
The form of the linear function is y = m x + b, where
m is the slope of the lineb is the y-intercept value y at x = 0∵ L represents the length of the candle remeaning unburned in inches
∵ t represents the time after the candle was lit in hours
∵ The relationship between L and t is linear
→ Put it in the form of the equation above
∴ L = m t + b, where b is the original length of the new candle
→ Use the table to find m
∵ m = [tex]\frac{L2-L1}{t2-t1}[/tex]
∵ (1, 9) and (6, 4) are two points in the given table
∴ t1 = 1 and L1 = 9
∴ t2 = 6 and L2 = 4
→ Substitute them in the rule of m above
∵ m = [tex]\frac{4-9}{6-1}[/tex] = [tex]\frac{-5}{5}[/tex] = -1
∴ m = -1
→ Substitute it in the equation above
∵ L = -1(t) + b
∴ L = -t + b
→ To find b substitute t by 1 and L by 9
∵ 9 = -(1) + b
∴ 9 = -1 + b
→ Add 1 to both sides
∵ 9 + 1 = -1 + 1 + b
∴ 10 = b
∵ b is the original length of the new candle
∴ The original length of the new candle is 10 inches

The longest leg of a right triangle is 12 feet and another side is 5 feet. Find the length of the remaining side.
Answer:
10.98 (approximately)
if you wan the exact answer, type into the google search bar:
"sqrt 119"
Step-by-step explanation:
in a right triangle, the longest leg is called the hypotenuse. To find the missing side, you need to use the Pythagorean theorem.
"a^2+b^2=c^2"
c = the hypotenuse
a and be are the other legs.
plug in the numbers.
5^2+b^2 = 12^2
25 + b^2 = 144
b^2 = 119
b = 10.98 (approximately)

Solve the system of equation 0.4x – 3y = 7
3x + 14y = 10 using Cramer's Rule.

4.1 When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
2x-15y-35
————————— • 5 = 0 • 5

Now, on the left hand side, the 5 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
2x-15y-35 = 0
Equation of a Straight Line
4.2 Solve 2x-15y-35 = 0
Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line 2x-15y-35 = 0 and calculate its properties
Graph of a Straight Line :
Calculate the Y-Intercept :
Notice that when x = 0 the value of y is 7/-3 so this line "cuts" the y axis at y=-2.33333
y-intercept = 35/-15 = 7/-3 = -2.33333
Calculate the X-Intercept :
When y = 0 the value of x is 35/2 Our line therefore "cuts" the x axis at x=17.50000
x-intercept = 35/2 = 17.50000
Calculate the Slope :
Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is -2.333 and for x=2.000, the value of y is -2.067. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of -2.067 - (-2.333) = 0.267 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = 0.267/2.000 = 0.133
Geometric figure: Straight Line
Slope = 0.267/2.000 = 0.133
x-intercept = 35/2 = 17.50000
y-intercept = 35/-15 = 7/-3 = -2.33333

Which statement about the distances is true?
Joe is installing a light fixture on a wall using a 10 foot ladder. A flower garden is planted along the wall, so Joe must place his ladder 6 feet away from the wall. How high up the wall will his ladder reach?
Answer:
The ladder is 8 feet high up on the wall.
Step-by-step explanation:
Let the height up of the ladder on the wall be represented by h. The ladder leaning on the wall, wall and distance of the foot of ladder from the wall form a right angled triangle.
So, applying the Pythagoras theorem;
[tex]/hyp/^{2}[/tex] = [tex]/adj 1/^{2}[/tex] + [tex]/adj 2/^{2}[/tex]
[tex]/10/^{2}[/tex] = [tex]/6/^{2}[/tex] + [tex]/h/^{2}[/tex]
100 = 36 + [tex]h^{2}[/tex]
so that,
[tex]h^{2}[/tex] = 100 - 36
= 64
⇒ h = [tex]\sqrt{64}[/tex]
= 8 feet
The ladder is 8 feet high up on the wall.

Chang knows one side of a triangle is 13 cm. Which set of two sides is possible for the lengths of the other two
sides of this triangle?
5 cm and 8 cm
6 cm and 7 cm
7 cm and 2 cm
8 cm and 9 cm
Answer:
8cm and 9cm
Step-by-step explanation:
The other sides are not greater than 13.
A: 5 + 8 = 13
B: 6 + 7 = 13
C: 7 + 2 = 9
However, D is greater than 13 and is the correct answer.
D: 8 + 8 = 16.

A map is drawn using a scale of 1 centimeter to 25 kilometers.
What actual distance is represented by a map length of 3.2 centimeters?
Enter the correct answer in the box.
Answer:
3.2 cm on map represents 80 kilometers of actual distance.
Step-by-step explanation:
It is given that the scale is:
1 cm = 25 km
And we have to find the distance that will be represented by 3.2 centimeters of length on the map.
Let x be the number of kilometers represented by 3.2 cm
[tex]\frac{1}{25} = \frac{3.2}{x}\\x = 3.2 * 25\\x = 80[/tex]
Hence,
3.2 cm on map represents 80 kilometers of actual distance.
