Answer:
x = - 3 , x = 2
Step-by-step explanation:
the solutions are the points on the x- axis ( y = 0 ) where the graph crosses.
solutions are then x = - 3 , x = 2
Answer:
3x + y = 21
x = 2.5
7.5 + y = 21
y = 13.5

Answer:
x
21
Step-by-step explanation:
(-2/3)x+13≥ -1
(-2/3)x≥ -14 (I subtracted by 13 on both sides)
x-14*(-3/2) (I divided by -2/3 on both sides)
x21
Based on the information given the gain or loss percent on the whole transaction is 1%.
<h3>Gain or loss percent:
</h3>
First step is to calculate the profit on the whole transaction
Profit=(8%×8,000)-(6%×8,000)
Profit=$640-$480
Profit=$160
Now let calculate the gain or loss percentage on the whole transaction
Gain or loss percentage=160/(8000+8000)×100
Gain or loss percentage=160/16000×100
Gain or loss percentage=1%
Inconclusion the gain or loss percent on the whole transaction is 1%.

Answer: 77°
Step-by-step explanation:
First we are going to find x and then insert it in 18x +5 to be able to get our <WZX
But to find x, we will have to apply the the exterior angle theorem
The exterior angle theorem state that : the exterior angle is equal to the sum of the two opposite interior anges
Using this theorem, then from the diagram above ;
18x + 5 = 48 + 8x - 3
we collect like term
18x - 8x = 48-3-5
10x = 40
Divide bothside by 10
10x/10 = 40/10
x = 4
but <WZX = 18x + 5
Then we substitute x=4
<WZX = 18(4) + 5
<WZX = 72 +5
<WZX =77
Therefore the measure of <WZX is 77°
