Answer:
2x-15
Step-by-step explanation:
Sara has x dollars
dina has 15 less which is
x-15
together it will be
x+x-15
=2x-15
Answer:
He can spend $1363 for everything else.
Step-by-step explanation:
x+637<=2000
x<=2000-637
x<=1363
if the problem is (5x^4y^3)^2 divided by 9
5^2 = 25
4*2 =8
3*2 =6
so you get (25x^8y^6)/9
if that isn't how the equation was supposed to be written let me know and I will edit my answer.
Let's write the parametric line
(x,y,z) = (0,2,8) + t(5,-1,4)
(5,-1,4) is called the direction vector of the line. It's normal to the plane
5x - y + 4z = constant
We get the constant by substituting the point (3,0,7),
5x - y +4z = 5(3) - 0 + 4(7) = 43
5x - y +4z = 43
