Answer:
True!
Step-by-step explanation:
4x - 3 = 13
Add 3 to both sides;
4x = 16
Divide both sides by 4;
x = 4
Let c represent the original amount that this guy had saved up.
He spent 25% of this amount, or 0.25c, on the printer.
To progress further, we have to know how much the printer cost.
Supposing that the printer cost $100 (which we do not know as a fact), this would be equal to 0.25c.
Thus, his savings originally amounted to c = $100/0.25 = $400.
Answer:
34
Step-by-step explanation:
(3 + 5i)(3 - 5i) = 9 - 25i^2
because i^2 = -1 9 - 25i^2 = 9 - 25x-1 = 34
hope this helped
If you are moving the decimal point to the left, the exponent is negative. If you move it to the right, the exponent is positive.
There is only one negative exponent here, and it is the first option.
So:
A number is being written in scientific notation. The student moves the decimal point to the left 3 places and A<span>. multiplies by 10^-3.</span>
Answer:
x=2, or x=1
Step-by-step explanation:
Given the equations as
f(x)=2x and
g(x)=2^x
Using a graph tool the equations will intersect at points (2,4) and (1,2)
x =2 or x=1
