Answer:
(-2,0) and (-4,-2)
Step-by-step explanation:
The solution to the system of equations is where the two graphs cross
They cross at (-2,0) and (-4,-2)
2) 2/7 divided 1/3 = 6/7
3) 4/9 times 3/8 = 1/6
4) 5/8 times 2/15 = 1/12
5) 1 divided 3/4 = 1 1/3
6) 1/8 times 8 =1/64
7) 2 1/4 times 1/6 = 3/8
8) 5/8 times 2 2/3 = 1 2/3
9) 1 1/8 times 4 = 4 1/2
10) 2 1/5 divided 11 = 1/5
11) 4 1/2 times 1 1/3 =6
12) 2 1/7 divided 3 3/7
13) 2 2/9 times 7 = 16
Answer:
$4.10
Step-by-step explanation:
Subtotal = (3 pairs of socks) x (price of socks):
Subtotal = (3 x $1.29) = $3.87
To get the overall total, you add tax, which is 6% of the subtotal:
6% of the subtotal = 0.06 x subtotal = 0.06 x $3.87 = $0.23
Subtotal + tax = $3.87 + $0.23 = $4.10
Answer:
x=11
Step-by-step explanation:
If A and B are complementary angles that means that the sum of them will equal 90. Because of this we turn the two separate equations into one that adds up to 90 to find X.
5x-2+3x+4=90
8x+2=90
8x=88
x=11
Answer: C) Cannot be done
Taking the square root of a negative number is not possible unless you involve complex numbers. If your teacher has not introduced that topic yet, then you just simply say "cannot be done" or something along those lines.
