Answer:

Step-by-step explanation:
<u><em>The correct question is</em></u>
What value of b will cause the system to have an infinite number of solutions?
y = 6x – b
–3x + 1/2y = –3
we have
----->equation A
-----> equation B
we know that
If the system has infinite number of solutions then, the equation A must be equal to the equation B
so
isolate variable y in the equation B

Multiply by
both sides

-------> new equation B
To find out the value of b, equate equation A and equation B


Answer:
20 fish.
Step-by-step explanation:

Answer:
x= 
Step-by-step explanation:
you might need a calculator to get the answer but since it is a right triangle the legs of the triangle in this case x and the
are the same length

notice, it goes 4,6 then 4, 6 again, and so on and so on
based on whatever exponent it may have
now, you're being asked, what 214 will give? 4 or 6?
Sin 45 = 62.5/h
h = 62.5 / sin 45
h = 88.3 cm
