Answer: 3n-1
The difference between each of the numbers is 3. This means that we have 3n.
If we assume that for the first number n=1, then 3*1=3, but the value we have is 2. This means that we must subtract 1 to get from 3 to 2.

Write an equation in slope-intercept form of the line that passes through the points (-2, - 11) and (3,9).
The equation is y=
Answer:
y = 4x - 3
Step-by-step explanation:
(-2, -11) & (3, 9)
First you want to find the slope of the line that passes through these points. To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)
Plug in these values:
(9 - (-11)) / (3 - (-2))
Simplify the parentheses.
= (20) / (5)
Simplify the fraction.
20/5
= 4
This is your slope. Plug this value into the standard slope-intercept equation of y = mx + b.
y = 4x + b
To find b, we want to plug in a value that we know is on this line: in this case, I will use the second point (3, 9). Plug in the x and y values into the x and y of the standard equation.
9 = 4(3) + b
To find b, multiply the slope and the input of x(3)
9 = 12 + b
Now, subtract 12 from both sides to isolate b.
-3 = b
Plug this into your standard equation.
y = 4x - 3
This is your equation.
Check this by plugging in the other point you have not checked yet (-2, -11).
y = 4x - 3
-11 = 4(-2) -3
-11 = -8 - 3
-11 = -11
Your equation is correct.
Hope this helps!
plz help and show how you did the math question
Answer:
[tex]x = - 3[/tex]
[tex]y = - 2[/tex]
Step-by-step explanation:
Since y=x+1 plug it into bottom equation as y.
[tex]x + 1= 5x + 13[/tex]
Subtract 1 from both sides
[tex]x = 5x + 12[/tex]
Subtract 5x from both sides
[tex] - 4x = 12[/tex]
Divide both sides by -4
[tex]x = - 3[/tex]
Now x=-3 into the top equation to find y
[tex] - 3 + 1 = - 2[/tex]

Step-by-step explanation:
A pile of sand has a weight of 60 kg
The sand is put into a small bag, a medium bag and a large bag in the ratio 2:3:7
Work out the weight of the sand in each bag
Small bag = 2x
Medium bag = 3x
Large bag = 7x
2x + 3x + 7x = 60
12x = 60
x = 60/12
x = 5
Small bag = 2(5) = 10 kg
Medium bag = 3(5) = 15 kg
Large bag = 7(5) = 35 kg
Done.

Metal A has a density of 2.4g/cm3 and metal B has a density of 1.8 g/cm3.Their masses are combined in the ratio 2 : 3 to make metal C which has a mass of 60 grams.Find the density of the metal C
Answer: 2 g/cm^3
Step-by-step explanation:
Remember the relation:
density = mass/volume.
Now, we know that:
Density of metal A = 2.4 g/cm^3
Density of metal B = 1.8 g/cm^3
We know that their masses are combined in the ratio 2:3
Then out of the total mass of metal C, 2 parts are from metal A and 3 parts are from metal B.
Mass of metal C = 60g
mass of metal A = (2/5)*60g =24g
mass of metal B = (3/5)*60g = 36g
Now that we know the mass of each metal, we can find their volumes by:
volume = mass/density
Volume of metal A = (24g)/(2.4g/cm^3) = 10cm^3
Volume of metal B = (36g)/(1.8g/cm^3) = 20cm^3
The total volume of metal C will be equal to the sum of the volumes of metal A and B, then:
Volume of metal C = 10cm^3 + 20cm^3 = 30cm^3
Then we know the volume and weight of metal C, then the density of metal C is:
Density of metal C = (60g)/(30cm^3)= 2 g/cm^3

In right triangle ABC, altitude CD with length h is drawn to its hypotenuse. We
also know AD = 12 and DB = 3.
Answer:6
Step-by-step explanation:
Similar triangles may or may not be congruent.
The value of h is 6.
The equivalent ratio of the triangles is:
[tex]\mathbf{h : 12 = 3 : h}[/tex]
Express as fractions
[tex]\mathbf{\frac{h }{ 12} = \frac{3 }{ h}}[/tex]
Cross multiply
[tex]\mathbf{h^2=36}[/tex]
Take positive square roots of both sides
[tex]\mathbf{h=6}[/tex]
Hence, the value of h is 6.

DeShawn and Mike each improved their yards by planting rose bushes and geraniums. They
bought their supplies from the same store. DeShawn spent $13 on 1 rose bush and 4 geraniums.
Mike spent $56 on 10 rose bushes and 3 geraniums. Find the cost of one rose bush and the cost of one geranium.
Answer:
Cost of 1 rose bush = x = $5
Cost of 1 geraniums = y = $2
Step-by-step explanation:
DeShawn and Mike each improved their yards by planting rose bushes and geraniums. They bought their supplies from the same store.
Let us represent:
Cost of 1 rose bush = x
Cost of 1 geraniums = y
DeShawn spent $13 on 1 rose bush and 4 geraniums.
x + 4y = 13..... Equation 1
x = 13 - 4y
Mike spent $56 on 10 rose bushes and 3 geraniums.
10x + 3y = 56....... Equation 2
We substitute 13 - 4y for x in Equation 2
10(13 - 4y) + 3y = 56
130 - 40y + 3y = 56
Collect like terms
- 40y + 3y = 56 - 130
-37y = -74
y = -74/37
y = $2
Solving for x
x = 13 - 4y
x = _13 - 4 × $2
x = $13 - $8
x = $5
Therefore,
Cost of 1 rose bush = x = $5
Cost of 1 geraniums = y = $2

Point F is on line CD. Find the measure of angle CFE.
Answer:
∠ CFE = 28°
Step-by-step explanation:
∠ CFE and ∠ DFE are adjacent angles and are supplementary, sum to 180°
∠ CFE + 152° = 180° ( subtract 152° from both sides )
∠ CFE = 28°
Adjacent angles share the common side as well as a common vertex (corner point), and they do not overlap. If we decompose the term "adjacent angles".
Adjacent angles:It's simple, and we see what it means: two angles that are next to each other.Its common side and vertex will be shared by the adjacent angles. If the total of two angles equals 180°, they are said to be supplementary angles. A linear pair is created when two additional angles are next to one another. 180° is equal to the sum of two adjacent supplementary angles.We have, ∠ EFD = 152°
∠ CFE and ∠ DFE are adjacent angles and are supplementary, summing to 180°
[tex]\therefore[/tex]
∠CFE + ∠EFD = 180° (Linear pair)
∠CFE +152° = 180°
∠CFE= 180°-152°
∠CFE= 28°

What is your hypothesis from the activity in the lesson? Will the shorter cylinder or taller cylinder have the larger volume? Or, will both cylinders have the same volume? Explain your reasoning using complete sentences. [Note: There is no wrong answer as long as you make a hypothesis and explain your reasoning using complete sentences.]
Answer:
Taller because it is bigger and more likely to have greater volume
Step-by-step explanation:
its correct 100%
The correct statement is,
''The taller cylinder have the larger volume than shorter cylinder.''
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Will the shorter cylinder or taller cylinder have the larger volume.
Since, We know that;
The volume of a cylinder is calculated by multiplying the area of the base by the height.
And, since the height of the taller cylinder is greater than the shorter cylinder, it is likely to have a larger volume.
Thus, The taller cylinder have the larger volume than shorter cylinder.
