Answer:
x = - 6
Step-by-step explanation:
Let x b number, according to instructions´ we must
1.-Multiply by 4
2.-Subtract 6
3.-Divide by 2
4.-Arturo says his new number - 15
4,.Which one was the original number ??
The maths expression for that is :
(4*x - 6 ) / 2 = - 15
we solve for x
4x - 6 = - 30
4x = - 24
x = - 6
For 
reading the fraction like f(x)/h only (f(x+h) start fraction f(x) / h end fraction), the answer is 
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:
The x variable has an exponent of 2
Step-by-step explanation:
To be a linear equation, the highest power must be 1 on the variables
2x^2 +y =7 is quadratic since x^2 has a power of 2
First, tan(<em>θ</em>) = sin(<em>θ</em>) / cos(<em>θ</em>), so if cos(<em>θ</em>) = 3/5 > 0 and tan(<em>θ</em>) < 0, then it follows that sin(<em>θ</em>) < 0.
Recall the Pythagorean identity:
sin²(<em>θ</em>) + cos²(<em>θ</em>) = 1
Then
sin(<em>θ</em>) = -√(1 - cos²(<em>θ</em>)) = -4/5
and so
tan(<em>θ</em>) = (-4/5) / (3/5) = -4/3
The remaining trig ratios are just reciprocals of the ones found already:
sec(<em>θ</em>) = 1/cos(<em>θ</em>) = 5/3
csc(<em>θ</em>) = 1/sin(<em>θ</em>) = -5/4
cot(<em>θ</em>) = 1/tan(<em>θ</em>) = -3/4
