Answer:
0
Step-by-step explanation:
There is no solutions other than 0
Move the 1st equation to get y by itself so it’s now y=-4x so you can substitute that in for the second equation 2y+x=-7 becomes 2(-4x)+x=-7
-8x+x=-7
-7x=-7
x=1
then plug that back in to find y
4(1)+y=0
4+y=0
y=-4
now you have x and y so your coordinate (the answer) is (1, -4) hope this helps!
Answer:
D. 1.06(3.19x + 1.20y + 1.20z)
Step-by-step explanation:
Since marker packs are 3.19 each, the cost of the marker packs she buys can be represented by 3.19x.
All spiral notebooks are 1.20 each, so the cost of the wide ruled notebooks can be represented by 1.20y.
The cost of the college ruled notebooks can be represented by 1.20z.
In the expression, all of these terms have to be added together and multiplied by 1.06 to calculate the sales tax.
So, the expression will be 1.06(3.19x + 1.20y + 1.20z)
D is the correct answer
=d/dx((t^4-6)^3) * (t^3+6)^4 + d/dx((t^3+6)^4) * (t^4-6)^3
=3*(t^4-6)^2 * (t^3+6)^4 * d/dx(t^4-6) + 4*(t^3+6)^3 * (t^4-6)^3 * d/dx(t^3+6)
=3*(t^4-6)^2 * (t^3+6)^4 * 4t^3 + 4*(t^3+6)^3 * (t^4-6)^3 * 3t^2
Simplify that if youd like
