Answer:
y = (2/3)x + 9
Step-by-step explanation:
Equation of a straight line is y = mx + b. You are trying to finish the equation.
Note that:
m = slope = 2/3
b = y-intercept = 9
Plug in the corresponding numbers to the corresponding variables:
y = mx + b --> y = (2/3)x + 9
y = (2/3)x + 9 is your equation.

Answer:
You end up paying 22% of the original price.
Step-by-step explanation:
The statement indicates that a store has clearance items that have been marked down by 60% and this means that you have to pay 40% of the price as:
100%-60%=40%
Now, the statement says that the are advertising an additional 45% off clearance items which means that you will have a 45% discount on the 40% of the original price. So, you have to calculate 45% of 40 and subtract that from 40 to find the percentage that you will end up paying:
40*45%=18
40-18=22
According to this, the answer is that you end up paying 22% of the original price.

Step-by-step explanation:
Answer:
x = 7.5
Step-by-step explanation:
We first labelled the diagram we get
DC = 8
AD = 10
CE = 6
BE = x
∴ AC =AD + DC = 18
∴ BC = BE + ED = x + 6
To Find :
BE = x =?
Solution:
Let DE || AC
In Δ ABC and Δ DEC
∠A ≅ ∠D …………..{corresponding angles ∵ DE || AB }
∠B ≅ ∠E ..............{corresponding angles ∵ DE || AB }
∠C ≅ ∠C ……….....{Reflexive Property}
Δ ABC ~ Δ DEC ….{Angle-Angle-Angle Similarity test}
If two triangles are similar then their sites are in proportion.
On substituting the given values we get
∴
