Answer:
(-1, 3) and (1, 5).
Step-by-step explanation:
Remember that graphically, the solutions for a system of equations are all the points where the graphs intersect.
In the graph of the system of equations, we see that the they intersect once at (-1, 3) and again at (1, 5).
Therefore, our two solutions to the system are (-1, 3) and (1, 5).
Answer:
76,000,000
Step-by-step explanation:
Look at the 100,000 place and see whether to round up or down - 8 is larger than 5, therefore 75,000,000 gets rounded up to 76,000,000
Use a calculator.
cause a calculator would prove that
Answer:
A. t=13 B. K= 23 C. t= 1 3/8
Step-by-step explanation:
A. 2t-30m=20
30 x 1/5= 6
2t-6+6=20+6
2t/2=26/2
t=13
B. 14+m=2k
14+12=2k
14+12=46
46/2=23
k=23
C. 1/8r+t=1
1/8 x (-3)= -3/8
1 - (-3/8)= 1 3/8
t= 1 3/8
Hope it helps!
