Answer:
infinite
Step-by-step explanation:
to simplify 4=4 meaning all solutions are true
Answer:
D
Step-by-step explanation:
You are given two complex numbers -i and 2+i.
For the complex number z=x+iy, the ordered pair (x,y) represents this complex number on the coordinate plane.
So, the numbers:
is represented by the ordered pair (0,-1)
is represented by the ordered pair (2,1).
Plot these two points on the coordinate plane and coonect them with a straight line. You'll get the last option of graph.
Answer:
Step-by-step explanation:
total weight is 4 tons.
ratio of weight of truck to weight of coal is 7:5....added = 12
so 7/12 of the total weight is the truck's
and 5/12 of the total weight is the coal
7/12 of 4 tons = 7/12 * 4 = 28/12 = 2 1/3 tons <== weight of truck
5/12 of 4 tons = 5/12 * 4 = 20/12 = 1 2/3 tons <== weight of coal
Answer:
4
Step-by-step explanation:
From the chioces give it would be 4
But it is actually 8
Answer:
4,8
Step-by-step explanation:
let the numbers be x and y
x+y=12
x-y=-4
add
2x=12-4=8
x=8/2=4
4+y=12
y=12-4=8
so numbers are 4 and 8
