Answer:
y=x+1
Step-by-step explanation:
First find the slope by subtracting the y values from both points and dividing it by the subtraction of the x values from both points:
-4--2/ -3--1= -2/-2= 1
so the slope is 1
Now find the y-intercept by plugging in the x and y from one of the points into the equation y=x+b
-3=-4+b
1=b
now plug the slope and y intercept in:
y=x+1
hope this helps :D
A city has 17391 registered Democrats and 20553 registered
Republicans. An organization wishes to survey equal proportions of
each group.
The council decides to survey 13 Republicans
How many Democrats should they survey? Democrats
Answer: The council should survey 11 Democrats.
Step-by-step explanation:
A proportional relationship is written as:
y = k*x
Where k is the constant of proportionality. y is the number of surveyed members, and x is the total number of registered members.
If we use the same proportion for each case, then we will use the same value of k.
We know that there are 20553 registered Republicans, and the council decides to survey 13 of them, then we will have the relation:
13 = k*20553
Now we can solve this for k:
13/20553 = k
Then the proportional relationship will be:
y = (13/20553)*x
The number of democrats they should survey can be found if we replace x by the number of registered Democrats, then we use x = 17391
this leads to:
y = (13/20553)*17391 = 11
The company should survey 11 Democrats.

Jay had 6 times as much money as Kay. Then Jay gave Kay $33. Jay now has twice as much money as Kay. How much did they each start with?
Answer:
Jay started with $148.5 and Kay with $24.75.
Step-by-step explanation:
With the information provided you know that Jay had 6 times as much money as Kay wich can be expressed as:
J=6K, where
J is the money Jay had
K is the money Kay had
Also, you know that Jay gave Kay $33 and Jay now has twice as much money as Kay, which would be:
J-33=2(K+33)
Now, you can replace J=6K in this equation and solve for K:
6K-33=2K+66
6K-2K=66+33
4K=66
K=24.75
Then, you can replace the value of K in J=6K:
J=6*24.75
J=148.5
According to this, the answer is that Jay started with $148.5 and Kay with $24.75.
5 grams of chucknorrisidium created, decays at a half-life of 16,000,000 Need 1 gram for experiments. How long before the is 1 gram remaining
Answer:
the time taken for the element to remain 1 gram is 38,400,000 unit.
Step-by-step explanation:
Given;
initial mass, m = 5 g
half life, t = 16,000,000 unit
The time taken for the element to remain 1 gram is calculated as;
mass remaining time
5 g 0
2.5 g 16,000,000
1.25 g 32,000,000
0.625 g 48,000,000
Interpolate to obtain the time at 1 gram;
1.25 g ---------------------------------- 32,000,000
1 g --------------------------------------------- x
0.625 g --------------------------------------- 48,000,000
[tex]\frac{1.25 - 1}{1.25 - 0.625} = \frac{32,000,000 - x}{32,000,000 - 48,000,000} \\\\\frac{0.25}{0.625} = \frac{32,000,000 - x}{-16,000,000} \\\\-4,000,000= 20,000,000 - 0.625x\\\\0.625x = 20,000,000 + 4,000,000\\\\0.625x = 24,000,000\\\\x = \frac{24,000,000}{0.625} \\\\x = 38,400,000[/tex]
Therefore, the time taken for the element to remain 1 gram is 38,400,000 unit.
with one litre of paint you can paint an area of 8m².how much paint will you need for a wall mural that is 10m wide and 3m high?
Answer: 3.75 liters
Step-by-step explanation:
1 liter = 8m^2
area of the wall = l x b (wide x high)
= 10 x 3
= 30m^2
so, quantity of paint needed = 30/8 = 3.75 liters

Answer:
Yes.
Step-by-step explanation:
Given that is the midpoint of AB and E is the midpoint of AC, AD =32cm, AE=19cm, and DE=39cm, determine the perimeter of DBCE
Answer:
since triangle AED similar to ACB

BD=32Cm mid point bisect it
Step-by-step explanation:
BC=2DE=2×39=78Cm

Ocean waves crash on the beach at a
velocity of 4.4 m/s. If the distance
between the crest of each wave is 4m,
find the frequency of the waves.
Answer:
f = 1.1 Hz
Step-by-step explanation:
Given that,
The velocity of an ocean wave, v = 4.4 m/s
The distance between the crest of each wave is 4 m.
We need to find the frequency of the waves.
The distance between the crest of a wave is called the wavelength of a wave.
The relation between the frequency, wavelength and the velocity of a wave is given by :
[tex]v=f\lambda\\\\f=\dfrac{v}{\lambda}\\\\f=\dfrac{4.4}{4}\\\\f=1.1\ Hz[/tex]
So, the frequency of the waves is 1.1 Hz.

Answer:
334
Step-by-step explanation:
[tex]\color{plum}\tt\bold{(a) \: 250}[/tex]
○=> Steps to derive correct answer :Money Jefferson needs to collect = $500
Selling price of each baked good = $2
Cost price of each baked good = 0.50
Number of baked goods Jefferson need to sell to meet his goal :
[tex] =\tt \frac{500}{2} \times 0.50[/tex]
[tex] =\tt 250 \times 0.50[/tex]
[tex]\color{plum} =\tt 125 \: baked \: goods[/tex]
Thus, Jefferson needs to sell 125 baked goods.
▪︎Therefore, the correct option is (a) 125.

What is the volume of the cuboid?The volume of cuboid is given by -
V{C} = Length x Breadth x Height
Given is a box with the dimensions of 10 ft x 5 ft x 6 ft.
We can write the volume of the box as -
V{b} = L x B x H
V{b} = 10 x 5 x 6
V{b} = 50 x 6
V{b} = 300 cubic feet
Therefore, the volume of the box with the dimensions of 10 ft x 5 ft x 6 ft is 300 cubic feet.
