Answer:
4.2 x 10⁶
Step-by-step explanation:
The problem says that there are 6x 10² times as many red blood cells as white blood cells. This means that you will need to multiply the given number of white blood cells, which is 7 x 10³ by 6x 10².
To do this, first you multiply the coefficients:
7 x 6 = 42
Next you combine the exponents of the 10s, because their bases are the same, we just add the exponents when you multiply them and copy the base:
10² x 10³ = 10⁵
So the result would be:
42 x 10⁵
However the following the form of scientific notation, you need to move the decimal one more time so that means you add one more to the exponent of 10.
4.2 x 10⁶
To find inverse, you switch x and y, and solve for y
Original: y=2x-1/3
Now:
x=2y-1/3
x+1/3=2y
(x+1/3)/2=y
y=
Answer:
(-1,2)
Step-by-step explanation:
y = -2x ______(1)
7x - 8y = -23 ________(2)
Substituting the value of y in eqn.(1) into eqn (2);
7x - 8(-2x) = -23
7x + 16x = -23
23x = -23
x = -1
y = -2(-1) = 2.
