Answer:
4/5x(v-7)=2
multiply both sides by 5/4, the reciprocal of 4/5
v-7=2x(5/4)
Express 2x(5/4) as a single fraction
v-7=<u>2</u><u>x</u><u>5</u>
4
Multiply 2 and 5
v-7=<u>1</u><u>0</u>
4
Reduce the fraction 10/4 to the lowest by extracting and cancelling 2
v-7=<u>5</u>
2
Add 7 to both sides
v=<u>5</u>+7
2
Covert fraction to 14/2
v=5/2+14/2
Since 5/2 and 14/2 have the same denominator, add them by adding their numerators
v=<u>5</u><u>+</u><u>1</u><u>4</u>
2
Add 5 and 14 together
v=<u>1</u><u>9</u>
2
Simplify each term .
6x^2 + 11x - 3/x + 2
Size got it right because it’s multiplied by 100
Trig was never my strong point but ok
remember the quotient rule
so
remember the pythagorean identity sin²(x)+cos²(x)=1
so
taht is the last option
thanks to jdoe0001 for showing me which identity to use
