Ten points to the best answer! :D-Standard form so no fractions and it is = 0
y = 2/7x - 16/7// Multiply by 7
7y = 2x - 16// Subtract 7y
0 = 2x - 7y - 16
Answer ->2x - 7y - 16 = 0
Also, if roots are reciprocals of each other
and
if they are equal in absolute value, but opposite in sign.
i am totally lost on this one. thanks to anyone who can help.-Since -2 is a root, the equ
x is a positive integer.
Which is larger?
A.The number of multiples of 3 between 100 and x+100.
B.The number of multiples of 7 between 100 and x+100.
C.They are equal.
D.There is not enough informati
Gradient of a curve is given by:
dy/dx= 2x/x^2+e
The curve passes through the point (0,2)
What is the equation of the curve?-∫ 2x/(x^2 + e) dx
Let u = x^2 + e
then du = 2x dx
y = ∫ 1/u du
y = ln
When 6 gallons of gasoline are put into a cars tank, the indictator goes from 1/4 of a tank to 5/8. What is the total capacity og the gasoline tank? I got 7 gallons because 5/8+1/4 = 6 gallons or 7/8
At what point do the curves r1 =

( ____, ____, ____)
Find their angle of intersection, θ correct to the nearest degree.
θ = ____°-When x, y, and z coordinates are all equal a
125x^3-64. i do not know how to factor this. and does anyone know how to simplify 32^(-2/5) in radical format?-USE FORMULAa^3 - b^3 = ( a-b) ( a^2 + ab + b^2)

If you ran 18 laps around the 400 yard track and your friend ran 7.5 km, who ran further? Show your steps.-18*400= 7200yds
7.5 km= 7500 m
A meter is bigger than a yard, so 7.5 km is farther.
You cou
m = m(subscript 0)/sqrt(1-(v/c)^2)
m = the mass of a particle
m(subscript 0) = the mass of the particle at rest
v = the speed of the particle
c = the speed of light
v > 0
Make v the subject of the
(32x^25y^20)^(1/5). I cant figure out how to simplify this expression-32=2^5, so 32^(1/5) is equal to 2.
For the variables x and y, multiply each of them by 1/5.
Your answer is 2x^5y^4.
I really need help with this question thank you so much
