6x + y = 28. The standard form of the equation that is parallel to y = -6x + 5 and goes through point (4, 4) is 6x + y = 28.
The equation is written in the slope-intercept form y = mx +b. So:
y = -6x + 5
The slope m = -6
Since the slopes of parallel lines are the same, we are looking for a slope line m = -6 and goes through point (4, 4).
With the slope-intercept form:
y = mx + b
Introducing the slope m = -6:
y = -6x + b
Introducing the point (4, 4):
4 = -6(4) + b
b = 4 + 6(4)
b= 24 + 4
b = 28
Then
y = -6x + 28
write the equation in standard form ax + by = c:
y = -6x + 28
6x + y = 28
10.5 is a rational number because it is a number that can be turned into a fraction.
10.5 = 10 1/2 = 21/2
Step-by-step explanation:
so whats the equation
In addition to mathematics and statistics, the arithmetic mean is used frequently in many diverse fields such as economics, anthropology, and history, and it is used in almost every academic field to some extent. For example, per capita income is the arithmetic average income of a nation's population i think
Answer:
25 in by 45 in.
Step-by-step explanation:
The length of the box will be x + 20 - 10 - 10 = x
The width of the box will be x - 10 - 10 = x - 20
The height of the box will be 10
So the volume = length x width x height
= x(x - 20)10 = 1250
= 
= 0
10(x + 5)(x - 25) =0
x = -5 x = 25
- 5 must be discarded since a length cannot be negative.
Therefore x = 25 in = width of piece of cardboard
x + 20 = 25 + 20 = 45 in = length of piece of cardboard
