Answer:
The geometrical relationships between the straight lines AB and CD is that they have the same slope
Step-by-step explanation:
Given
Required
The relationship between AB, CD
Since AB is a straight line and O is the origin, then:
Where:
====>
====>
This implies that:
So:
So, we have:
Calculate the slope (m) of
For AB
For CD
By comparison:
This implies that both lines have the same slope
To solve linear equations, we must perform inverse operations on both sides of the equal sign to <em>cancel values out</em>.
We perform inverse operations to<em> combine like terms</em>. This means to get x to one side and everything else on the other.
<h2>Solving the Questions</h2><h3>Question 1</h3>Because 7 is being added to x, subtract it from both sides:
Because x is being multiplied by 5, divide both sides by 5:
Therefore. .
Here, we can group all the x values on the left side of the equation. Subtract 5x from both sides:
To isolate x, subtract 4 from both sides:
Divide both sides by 2:
Therefore, .
Answer:
1%
Step-by-step explanation:
S.P of each radio=$ 2288
Total S.P=$4576
Gain=10%
Lose=10%
C.P=
C.P=
By using the formula
C.P of one radio=$2080
C.P of another radio==$2542.2
Total C.P of two radios=2080+2542.2=$4622.2
Total C.P >Total S.P
Loss=S.P-C.P
Loss=4622.2-4576=$46.2
Loss%=
Loss %=1%
Hence, his loss 1%
