Answers
Answer : Graph the line that contains the point (-2,6) and has a slope of -1/3
Answer:
[tex]y = - \frac{1}{3} x - \frac{20}{3} [/tex]
Step-by-step explanation:
Use the following equation [tex]y - y_{1} = m(x - x_{1})[/tex]your x1 and y1 are from the point you're given, so the ( -2 , 6 ) will be x1 = -2 and y1 = 6m is the slope, so m = -1/3Then we just substitute into the equationso [tex]y - (6) = - \frac{1}{3} ( x - ( - 2)) \\ y - 6 = - \frac{1}{ 3} (x + 2) \\ y - 6 = - \frac{1}{3} x - \frac{2}{3} \\ y - 6 + (6) = - \frac{1}{3} x - \frac{2}{3} + 6 \\ y = - \frac{1}{3} x - \frac{20}{3} [/tex]So that's our equationRelated Questions
A new LED light bulb uses 10 watts of power. Since energy = power × time , then the energy used for this light bulb can be found my multiplying the power times the time the bulb is lit. If the bulb is lit for one hour, the energy used will be 10 watt*hours or 10 Wh. If three 10 watt bulbs in one room are kept on for 5 hours, how many watt*hours of energy are used?
Answers
9514 1404 393
Answer:
150 Wh
Step-by-step explanation:
We know the energy per bulb is 10 Wh per hour, so the total energy used by 3 bulbs in 5 hours is ...
(10 Wh/(bulb·hour))×(3 bulbs)×(5 hours) = 10·3·5 Wh = 150 Wh

C. 36 degrees
Step-by-step explanation:
Exterior angles sum = 360 degrees
72+144=216

Supplementary angles(Angles on opposite sides of the transversal) sum = 180
180-144= 36
Therefore, x=36 degrees

A farmer has a rectangular plot of land. There is a bother identical plot of land 100 yards east and 100 yards north. Find the combined area of the two plots of land
Answers
Answer:
Step-by-step explanation:
Area of a rectangular plot = Length × width
With the aid of the diagram attached below.
For plot 1:
The area = ( 60 - 20 ) × ( 80 - 20 )
Area = 40 × 60
Area = 2400 sq yard
For plot 2:
Area = (160 - 120 ) × ( 180 - 120 )
Area = 40 × 60
Area = 2400 sq yard
Therefore, the combined area of the two plots of land = 2400 + 2400
= 4800 square yards

A cone has height h and a base with radius r. You want to change the cone so its
volume is halved. What is the new height if you only change the height? What is the
new radius if you only change the radius? Explain.
Answers
9514 1404 393
Answer:
a) h/2
b) r/√2 = (r√2)/2
Step-by-step explanation:
a) The volume of a cone is proportional to height. If the volume is halved, then the height will be halved.
The new height will be h/2.
__
b) The volume is proportional to the square of the radius. If the volume is halved, the square of the radius is halved. The new radius will be ...
(r')² = r²/2
r' = r/√2 = (r√2)/2 . . . radius of half-volume cone

Answers
Answer: $277.99
Step-by-step explanation:
There are 52 weeks in a year. Assuming the architect would get paid every week, you would divide their salary by 52.

4-cup carton of fruit punch for $0.80
Answers
Answer:
$0.90
Step-by-step explanation:
1 quart = 2 pints
Write a proportion:
$1.80 / 4 pint = x / 2 pint
Cross multiply:
4x = 3.60
Divide:
x = 0.90
The price per quart is $0.90.
Answer:
4-quart carton of fruit punch for $2.08
Step-by-step explanation:
4-quart carton of fruit punch for $2.08
2.08 : 4 = 0.52
check your work: 0.52 x 4 = 2.08
so for the first offer you will be paying $0.52 per quart .
4-cup carton of fruit punch for $0.80
1 cup = 0.25 quarts
4 cups = 1 quart
0.80 : 1 = 0.80
for the second offer you will be paying $0.80 per quart of fruit punch. 4-quart carton of fruit punch for $2.08 is a better buy because you will be paying for each quart than in first offer.

Which inequality has the graph shown below?
Answers above ^
Answers
Answer:
The inequality the graph has shown is y < 2x - 3 ⇒ C
Step-by-step explanation:
The form of the linear equation is y = m x + b, where
m is the slope of the lineb is the y-interceptFrom the given figure
∵ The line drawn is a dashed line
→ That means the sign of inequality without the equal sign
∴ The sign of the inequality is without the equal sign
∵ The shaded area is under the line
→ That means the sign of the inequality is smaller than
∴ The sign of the inequality is <
∵ The line intersects the y-axis at point (0, -3)
→ That means the y-intercept is -3
∴ The y-intercept = -3 ⇒ (value of b in the equation of the line)
∵ There is only one answer has sigh < and y-intercept -3
∴ The inequality the graph has shown is y < 2x - 3

m<EDF = 180 - 148 = 32° (angles on a straight)
m<EFD = 180 - 140 = 40°(Angles in a straight line)
m<DEF = 180 - (m<EDF + m<EFD) (sum of triangle)
m<DEF = 180 - (32 + 40)
m<DEF = 180 - 72
m<DEF = 108°

Use the dot plot to find the MEAN.
Answers
Answer:
Step-by-step explanation: To find the mean of the dot plot, you will need to add all of the dots together.
For example: Above 2, there are 3 dots , so you would need to multiply 2 by three to get 6 dots above the number 2.
Do that for all of the numbers on the dot graph from 1 - 6, and you will have this equation:
1 + 6 + 18 + 20 + 15 + 12
Next, you will need to add all those numbers together and you will get 72.
Lastly, divide by how many numbers there are, and there are 6 numbers.
So, that will be 72/6 which is 12.
Your answer will be 12.

Answer:
[tex]y=-\frac{1}{20} x + 20[/tex]
Step-by-step explanation:
The slope equation is always [tex]\frac{rise}{run}[/tex]. In this case, the gallons went down by 1- so we can call the rise -1. When it went down by 1, the miles went up by 20- so we can call the run 20. This gives us a fraction (the "m" value) to put in the slope equation [tex]y=mx+b[/tex]. To find the y intercept (the "b" value), you find out what y is when x = 0, which is given in the chart: 20.
