Answer:
Step-by-step explanation:
Given: Marisa bought four bottles
Price of each bottle is $0.95.
Solving with the factors as given to find the total cost paid by Marisa.
Total cost= 
∴ Total cost paid by Marisa is $3.8.
As given to write an equation with the same product as the total cost but different factors.
∴ Lets assume the number of bottles bought by Marisa be "5" and cost of each bottle be "x"
We already find the total cost she paid is $3.8.
Now, writing an equation with different factors, as total cost remain same.
Dividing both side by 5
we get x= $ 0.76
∴ The required equation is
1)Parallel means they have to have the same slope. Since our equation is y=2/3x+1, a line parallel to that would be(using out points) -5=2/3(-4)+b.
To find the y-intercept, solve for "b".
b=-7/3
Our equation would then be y=2/3x-7/3
2)Perpendicular lines have opposite-reciprocal slopes. our previous equation was y=2/3x+1, so our new equation would be -5=-3/2(-4)+b. Now lets solve for b.
b=-11
So our perpendicular equation would be y=-3/2x-11
Hope that was helpful. :)
In that statement of a function, 'a', 'b', and 'c' all represent
plain old ordinary constant numbers.
Answer:
just using normal x and y coordinates
4x + 2y = 36
where x = 5
that is 4×5 = 20
where y = 8
that is 2×8 = 16.
Answer: 6units
Step-by-step explanation:
Since it is a regular polygon, and it has 3 equal sides it means the polygon is a quadrilateral.
From the diagram,
5 - 2x = -4x + 9 ( side of quadrilateral )
Solving for x in the equation
-2x + 4x = 9 - 5 ( collection of like terms in simple linear equation )
2x = 4
Divide through by the coefficient of x which is 2
x = 2.
Therefore, the perimeter of the polygon which equals to the total length of the polygon is
Perimeter = 2 + 2 + 2
= 6units
