Answer:
Step-by-step explanation:
We want a line parallel to 3x − 4y = 7. Any such line will have an equation of the same form but a different constant.
If the new line is to pass through the point (-4, -2), replace x with -4 and y with -2. We obtain:
3(-4) − 4(-2) = -12 + 8 = -4. Thus, the desired new equation is 3x − 4y = -4.
This could also be written as 3x − 4y + 4 = 0. We could also solve this for y, obtaining:
3x + 4 = 4y, or y = (3/4)x + 1.
Answer:
Amount of phone after 3 year = $290.7 (Approx.)
Step-by-step explanation:
Given:
Amount of phone = $350
Depreciation rate = 6% = 0.06
Find:
Amount of phone after 3 year
Computation:
A = p[1-r]ⁿ
Amount of phone after 3 year = Amount of phone[1-Depreciation rate]ⁿ
Amount of phone after 3 year = 350[1-0.06]³
Amount of phone after 3 year = 350[0.94]³
Amount of phone after 3 year = 350[0.83054]
Amount of phone after 3 year = $290.7 (Approx.)
One.
A term is, in other words, each part of an expression.
Ex.
2 + 3x - 478923c = 3.14
Here, you have four terms total, three on one side of the equation, and one on the other.
Answer:
The expression that represents the perimeter of the rectangle is "12*x + 18", where "x" is the length of the rectangle.
Step-by-step explanation:
In order to solve this question we were given an expression that relates both dimensions of the rectangle. This expression in a mathematical form where "x" is the length and "y" is the width is shown bellow:
y = 9 + 5*x
The perimeter of a rectangle is given by:
perimeter = 2*length + 2*width
perimeter = 2*x + 2*(9+5*x)
perimeter = 2*x + 18 + 10*x
perimeter = 12*x + 18
The expression that represents the perimeter of the rectangle is "12*x + 18", where "x" is the length of the rectangle.
