Here's a graph of a linear function. Write the
equation that describes that function.
Express it in slope-intercept form.
Answer:
the graph has a positive slope with a y-intercept of 5
y = 1/4x + 5
Step-by-step explanation:
i found the slope by using points (0,5) and (4,6)
slope formula says to subtract the y-values and divide by difference of x-values:
(6-5) / (4-0) = 1/4

write the equation y=x-4 in standard form (Ax + By = C)
Answer:
x - y = 4
Step-by-step explanation:
Given
y = x - 4 ( add 4 to both sides )
y + 4 = x ( subtract y from both sides )
4 = x - y , that is
x - y = 4 ← in standard form

How old is Maggie?
Maggie is
years old
Answer:
Let M = Maggie's age
B = Brother's age
Then M + B = 32
B = 2M - 7
Then M + 2M - 7 = 32
3M= 39 = 13
M= 13

Which is the most economic way to lessen electric consumption?
a.Use all appliances which are not so important
b.More appliances will be used for relaxation
c.Use only appliances to the most important task in the house
d.Don’t mind the high bill anyway you have have much money to pay for bill
An electric bill shows a previous reading of 2156kwh and a present reading of 2268kwh How many kilowatt-hour was consumed?
a.102kwh
b.112kwh
c.112kwh
d.122kwh
Compute the electrical consumption of Falogme Family if the present reading in their eletric meter is 5623kwh and the previous reading is 5512kwh
a.110kwh
b.111kwh
c.112kwh
d.121kwh
Answer:
1) c. Use only appliances to do the most important task in the house.
2) b. 112kwh
3) b. 111kwh
Step-by-step explanation:
Energy can be defined as the ability (capacity) to do work and it's measured in Joules. The various forms of energy are solar energy, chemical energy, thermal energy, wind energy, nuclear energy, electrical energy, etc.
Power can be defined as the energy required to do work per unit time.
Mathematically, it is given by the formula;
[tex] Power = \frac {Energy}{time} [/tex]
Energy consumption is the total amount of power used by an electronic device per unit time and it's measured in Watt-hour or Kilowatt-hour.
Mathematically, it is given by the formula;
[tex] Energy = power * time [/tex]
Generally, the most economic way to lessen electric consumption is by ensuring only the important electrical appliances are used at all times.
2. Given the following data;
Previous reading = 2156 KWh
Present reading = 2268 KWh
To find how many kilowatt-hour was consumed;
Energy consumption = present reading - previous reading
Energy consumption = 2268 - 2156
Energy consumption = 112 KWh
3. Given the following data;
Previous reading = 5512 KWh
Present reading = 5623 KWh
To find the electrical consumption of Falogme Family;
Electrical consumption = present reading - previous reading
Electrical consumption = 5623 - 5512
Electrical consumption = 111 KWh

An animal shelter provides shelter for dogs and cats. The animal shelter currently has a total of 117 animals. If the number of cats is 3 more than 5 times the number of dogs, how many dogs and cats are currently at the animal shelter?
Answer:
98 cats and 19 dogs
Step-by-step explanation:
cat = c
dog = d
The animal shelter currently has a total of 117 animals
c + d = 117
c = 117 - d
the number of cats is 3 more than 5 times the number of dogs
c = 3 + 5d
subtitute c
117 - d = 3 + 5d
117 - 3 = 5d + d
114 = 6d
6d = 114
d = 114/6 = 19
so, the cat is 117-19 = 98
find the perimeter of the trapezoid
Answer:
Perimeter you add up all the sides. If it is a horizontal or vertical line, you just write those values for the side lengths. For the slanted one, I would use pythagorean theorem to solve it.
Step-by-step explanation:
If we make a right triangle using vertical and horizontal lines. We will find that a = 6, and b = 12. Find the square root of the sum of a squared plus b squared. That will tell you C. Then add C to the other 3 sides and that will give you the perimeter.
Write an equation of the line in point slope form given the information below slope= 7 point (1,4)
Answer:
y-4=7(x-1)
Step-by-step explanation:
y-y1=m(x-x1)
y-4=7(x-1)
The equation of the line with a slope of 7, passing through the point (1,4), in point-slope form is y = 7x - 3.
To write the equation of a line in point-slope form, we use the formula:
y - y₁ = m(x - x₁)
where m represents the slope of the line and (x₁, y₁) represents the coordinates of a point on the line.
In this case, the given slope is 7 and the point (1,4) lies on the line. Plugging in the values into the formula, we have:
y - 4 = 7(x - 1)
Simplifying the equation, we can distribute the 7:
y - 4 = 7x - 7
To isolate y, we can add 4 to both sides of the equation:
y = 7x - 7 + 4
y = 7x - 3

In the diagram below,
Answer:
<H = 40
Step-by-step explanation:
Complementary angles add to 90 degrees
2x+10 + x+20 = 90
Combine like terms
3x+30 = 90
Subtract 30
3x+30 -30 = 90-30
3x = 60
Divide by 3
3x/3 = 60/3
x = 20
<H = x+20 = 20+20 = 40
What is the image of the point(2,-5) after a rotation of 90 degree counterclockwise about the origin
Answer:
(-2,5)
Step-by-step explanation:
When a point is rotated counterclockwise 90 degrees about the origin then the coordinates of the image will be (x,y) → (-y,x).
Here, (5,2)→(-2,5)
Therefore , if (5,2) is rotated counterclockwise 90 degrees about the origin its image will be point (-2,5).
Hence, if (5,2) is rotated counterclockwise 90 degrees about the origin its image will be point (-2,5).

A map has a scale of 1:200000 How far is it from Belfast to Larne in Km if the distance on the map is 7.8cm
Answer:
15.6km
Step-by-step explanation:
Given the map scale 1:200000
1cm on the map represents 200000 cm on ground or in actual distance
Hence, if distance from Belfast to Larne is 7.8vm on map ;
Actual distance will be :
7.8 * 200000 = 1560000 cm
Converting to km :
Recall :
1000 m = 1km
100 cm = 1 m
Hence,
100000 cm = 1km
Therefore, (1560000 / 100000) km
= 15.6km
Hence, distance between Belfast and Larne is 15.6km

Laura wants to place one flowerpot every meters along the path from the gate to the main entrance of her home. The path is meters long. How many flowerpots will she need?
Answer:
16 flower pots
Step-by-step explanation:
Length of path = 12 m long
Flower pot is placed every 3/4 m along the path ;
Number of flower pots required = (length of path / length of distance placed)
Number of flower pots required = 12 ÷ 3/4
12 * 4/3 = (12 * 4) / 3 = 48 / 3 = 16 flower pots

Vanessa received a $12,000 loan from the bank to buy a motorcycle. She will repay the loan to the bank with an $300 monthly payment.
Answer:
40 months
Step-by-step explanation:
It will take Vanessa 40 months or 3 years and 4 months to repay the bank their loan amount(without interest ofc).
Answer:
Time = 42 months
Step-by-step explanation:
[tex]Monthly \ payment = [rate + \frac{rate}{(1 + rate)^{month}-1}] \times principal[/tex]
Monthly payment = 300
Principal = 12000
[tex]Rate \% = \frac{300}{12000} \times 100 = \frac{30}{12} = \frac{5}{2} = 2.5[/tex]
Substituting and solving Months = 42 months

We find the surface area of the cylinder
= 2πr(r + h)
r = Diameter /2 = 100 feet/2
r = 50 feet
h = 1 feet

HELP ASAP IM BEING TIMEDD
Answer:
53/100
Step-by-step explanation:
First, we convert the fraction to a decimal number by dividing the numerator by the denominator:
8 / 15 = 0.533
There are two parts to the decimal number above:
Integer Part: 0
Fractional Part: 533
Now, we will make the Fractional Part just two digits (nearest hundredth) by using our rounding rules.*
In this case, Rule I applies, so 8/15 (or 0.533) rounded to the nearest hundredth in decimal format is:
0.53
Next, we will make 8/15 rounded to the nearest hundredth in fraction format. Since you can divide our decimal format answer above by 1 and keep the same value, you can make it like this:
0.53 = 0.53/1
Then, we multiply the numerator and denominator by 100 to get rid of the decimal point:
(0.53 x 100) / (1 x 100) = 53/100
That's it. 8/15 rounded to the nearest hundredth is displayed below (simplified if necessary):
53/100
Answer:
53.33% is the correct answer
