Answer:
L(x,y) = (2,-8,0) + (0,-1,1)*t
Step-by-step explanation:
for the planes
x + y + z = -6 and y + z = -8
the intersection can be found subtracting the equation of the planes
x + y + z - ( y + z ) = -6 - (-8)
x= 2
therefore
x=2
z=z
y= -8 - z
using z as parameter t and the point (2,-8,0) as reference point , then
x= 2
y= -8 - t
z= 0 + t
another way of writing it is
L(x,y) = (2,-8,0) + (0,-1,1)*t
Answer:
p=4CP - 26
C= p/4P + 13/2P
P= P/4C +13/2C
Step-by-step explanation:
Divide both sides of the inequality by 4 but don’t flip the symbol.
You only flip the inequality symbol if you divide by a negative number.
If you’re solving for x (which you are), you want to get x by itself. The only way to do that is to divide by 4.
Answer: estimate 7
exact: 6 7/15
Step-by-step explanation: for the estimate round 3 4/5 to 4 and 2 2/3 to 3 and 4 + 3 = 7
for the exact number convert 3 4/5 to 3 12/15
and convert 2 2/3 to 2 10 /15
then add 3 + 2 = 5
and 12/15 + 10/15 = 22/15
convert 22/15 to a mixed number which is 1 7/15
then 5 + 1 7/15
answer 6 7/15

A. First move all to the left side of the equation(Normal form)
x^3 - 49x= 0
B. Factor out an x, which is the GCF (Factored form)
x(x^2 - 49) = 0
C. Find solutions by making each x piece equal to 0. The first part is just x=0 and the second part is just factoring the difference of squares and then solving.
x=0, x^2 - 49 =0
x=0, x + 7 = 0, x - 7 = 0
Therefore, the answers for Part C are:
x = 0, x = -7, x = 7
