Answer:
-4,-5/2
Step-by-step explanation:
2x^2+3x-20 =0
2x^2+8x-5x-20 =0
2x(x+4)-5(x+4) =0
(x+4)(2x-5) =0
Either,
x+4=0
x=-4
Or,
2x-5=0
2x=5
x=5/2
Answer:
The total money spend on total tax of purchase is $4.625
Step-by-step explanation:
Given as :
The percentage of sales tax applied on gasoline purchase = 8.5%
The percentage of excise tax applied on gasoline purchase = 10%
The price of gasoline before tax = $25
Let The total money on total tax of purchase = $x
Now, Total percentage of tax = sales tax percentage + excise tax percentage
i.e Total percentage of tax = 8.5% + 10%
Or, Total percentage of tax = 18.5%
<u>Again</u>
total money on total tax of purchase = $25 of total total tax percentage
Or, x = $25 × 18.5%
Or, x = $25 × 
Or, x = $25 × 0.185
∴ x = $4.625
So,The total money on total tax of purchase = x = $4.625
Hence,The total money spend on total tax of purchase is $4.625 Answer
Answer:
<h3>x = -7</h3>
Step-by-step explanation:
2x + 3 = x – 4
2x - x = -3 - 4
x = -7
Answer: y < 1
<u>Step-by-step explanation:</u>

The first function has the range of y < -4
The second function has the range of y = -3
The third function has the range of y < 1
The largest y-value is 1 and the smallest y-value is -∞, therefore the range (y-values) are from -∞ to 1 → y < 1
