The complete table is shown below:
Graph Vertical Change Horizontal Change Slope
A 6 3 2
B 2 8 1/4
C 40 20 2
Step-by-step explanation:
Graph A
From graph A, it is clear that
(x₁, y₁) = (1, 3)
(x₂, y₂) = (4, 9)
Vertical change = y₂ - y₁ = 9 - 3 = 6
Horizontal change = x₂ - x₁ = 4 - 1 = 3
Using the formula
Slope = m = Vertical Change / Horizontal Change
= [y₂ - y₁] / [x₂ - x₁]
= [9 - 3] / [4 - 1 ]
= 6 / 3
= 2
Thus, the slope of the line = m = 2
Graph B
From graph B, it is clear that
(x₁, y₁) = (2, 1.5)
(x₂, y₂) = (10, 3.5)
Vertical change = y₂ - y₁ = 3.5 - 1.5 = 2
Horizontal change = x₂ - x₁ = 10 - 2 = 8
Using the formula
Slope = m = Vertical Change / Horizontal Change
= [y₂ - y₁] / [x₂ - x₁]
= [3.5 - 1.5] / [10 - 2 ]
= 2 / 8
= 1/4
Thus, the slope of the line = m = 1/4
Graph C
From graph C, it is clear that
(x₁, y₁) = (10, 35)
(x₂, y₂) = (30, 75)
Vertical change = y₂ - y₁ = 75 - 35 = 40
Horizontal change = x₂ - x₁ = 30 - 10 = 20
Using the formula
Slope = m = Vertical Change / Horizontal Change
= [y₂ - y₁] / [x₂ - x₁]
= [75 - 35] / [30 - 10 ]
= 40 / 20
= 2
Thus, the slope of the line = m = 1/4
Therefore,
The complete table is shown below:
Graph Vertical Change Horizontal Change Slope
A 6 3 2
B 2 8 1/4

A hot air balloons height varies directly as the balloons ascents the time in minutes. A hot air balloon rises at 350 feet in five minutes. Write a direct variation equation.
Answers
Answer:
h α t
h = kt
k = h/t
350 = k5
350/5 = k
k = 70
Step-by-step explanation:
Given that :
Ballon height varies directly as the Ascent time in minutes
Height of hot air Ballon rises 350 feets in 5 seconds
Expressing as a direct variation :
Let height of Ballon = h
Time it takes to rise = t
h α t
h = kt
k = h/t
350 = k5
350/5 = k
k = 70

Cost of cashews cost $2 more than peanuts. Gabriel orders 4 cans of cashews and 3 cans of peanuts the total cost was $56. Write an equation for the cost of peanuts
Answers
Answer:
3x = 56 - (4x + 8)
Step-by-step explanation:
Let
Cost of peanut = x
Cost of Cashew = x + 2
Total Cost = Cost of Cashew + Cost of peanut
56 = (x+2) * 4 + x * 3
Cost of peanut: 3x = 56 - (4x + 8)
Total Cost = Cost of Cashew + Cost of peanut
56 = (x+2) * 4 + x * 3
56 = (4x + 8) + 3x
56 = 4x + 8 + 3x
56 = 7x + 8
56 - 8 = 7x
48 = 7x
x = 48/7
x = 6.86

Answer:
14) [tex]f(10) = 10[/tex], 15) [tex]f(-2) = -2[/tex], 16) [tex]f(a) = a[/tex], 17) [tex]f(a+b) = a+b[/tex], 18) [tex]g(10) = 38[/tex], 19) [tex]g(-2) = -22[/tex], 20) [tex]g(a) = 5\cdot a - 12[/tex], 21) [tex]g(a+b) = 5\cdot a +5\cdot b -12[/tex]
Step-by-step explanation:
Let [tex]f(x) = x[/tex] and [tex]g(x) = 5\cdot x - 12[/tex], we proceed to resolve on each case:
14) [tex]f(10)[/tex]
[tex]f(x) = x[/tex]
[tex]f(10) = 10[/tex]
15) [tex]f(-2)[/tex]
[tex]f(x) = x[/tex]
[tex]f(-2) = -2[/tex]
16) [tex]f(a)[/tex]
[tex]f(x) = x[/tex]
[tex]f(a) = a[/tex]
17) [tex]f(a+b)[/tex]
[tex]f(x) = x[/tex]
[tex]f(a+b) = a+b[/tex]
18) [tex]g(10)[/tex]
[tex]g(x) = 5\cdot x - 12[/tex]
[tex]g(10) = 5\cdot (10) -12[/tex]
[tex]g(10) = 38[/tex]
19) [tex]g(-2)[/tex]
[tex]g(x) = 5\cdot x - 12[/tex]
[tex]g(-2) = 5\cdot (-2) -12[/tex]
[tex]g(-2) = -22[/tex]
20) [tex]g(a)[/tex]
[tex]g(x) = 5\cdot x - 12[/tex]
[tex]g(a) = 5\cdot a - 12[/tex]
21) [tex]g(a+b)[/tex]
[tex]g(x) = 5\cdot x - 12[/tex]
[tex]g(a+b) = 5\cdot (a+b) -12[/tex]
[tex]g(a+b) = 5\cdot a +5\cdot b -12[/tex]

Multiply the bottom equation by 3 then subtract the bottom equation from the top equation
Multiply the bottom equation by -3/2 then add the equations.
Multiply the top equation by-3. then add the equations
Answers
Answer:
Multiply the bottom equation by -3/2 then add the equations.
Multiply the top equation by-3. then add the equations
Step-by-step explanation:
Given the simultaneous equation
2x- 6y=6 ... 1
6x - 4y = 2 ... 2
To eliminate a variable, we have to make the coefficient of one of the variable to be the same.
Multiply equastion 1 by -3
-6x+18y= -18
6x - 4y = 2
Add the result:
-6x + 6x + 18y-4y = -18+2
18y-4y = -18+2
14y = -18
y = -9/7
Another way is to Multiply the bottom equation by -3/2 then add the equations.
Multiplying equation 2 by -3/2 will give;
6x(-3/2) - 4y(-3/2) = 2(-3/2)
-9x + 6y = -3
Add to equation 1;
2x- 6y=6
-9x + 2x + 0 = -3+6
-7x = 3
x = -3/7
Hence the correct two options are;
Multiply the bottom equation by -3/2 then add the equations.
Multiply the top equation by-3. then add the equations

A force of 450 N is exerted with a pressure of 15 N/m2.
Calculate the area to which the force has been applied.
Answers
134356377489486467347
Step-by-step explanation:
Force (F) = 450 N
Pressure (P) = 15 N/m² or 15 pa
Area (A) = ?
We know the force acting normally per unit area is pressure so,
P = F / A
15 = 450 / A
A = 450 / 15
A = 30 m²
The area to which the force has been applied is 30 m².
