Answer: -1/2
Explanation: -4y > 2x + 4; isolate the y by dividing both sides by -4 and get:
y = -2/4x + 4; simplify
y = -1/2x + 4
In y = mx + b; m is the slope
In this case, -1/2 is the slope
Answer:

Answer:
Scale = 5ft/in
Step-by-step explanation:
Given
Scale Measurement = 6in.
Actual Width = 30ft
Required
Scale Ratio.
The scale ratio can be calculated as thus:
Scale Ratio = Actual Measurements ÷ Scale Measurements
Scale Ratio = 30ft ÷ 6in
Scale Ratio = 30ft/6in
Simplify to lowest terms
Scale Ratio = 5 ft/1 in
Scale Ratio = 5ft/in
This can also be represented as follows;
Scale Ratio = 5ft : 1in
This means that 5 ft on the actual measurements is represented by 1inch on the scale.
Answer:
6x - 24y
Step-by-step explanation:
First, eliminate the braces by doing the multiplications:
-30x - 12y + 36x - 12y
Then group together the same variables:
6x - 24y
arguably, you could factor out a 6 and get:
6(x-4y)
but it is a matter of taste if that is simpler...
Answer:
absolute value of the determinant, adjacent to, equal to
Step-by-step explanation:
The absolute value of a determinant of the
columns are the vectors and they define the
of a
which is adjacent to one another and is equal to the
of the
.
The determinant is a real number. They are like matrices, but we use absolute value bars to show determinants whereas to represent a matric, we use square brackets.
