Answer:
Standard form is a way of writing down very large or very small numbers easily. 103 = 1000, so 4 × 103 = 4000
Step-by-step explanation:
If x+y=k, then x=k-y. Substitute k-y for x in the other equation. So (k-y)-y=k. k-2y =k which means y has to be 0 (both k's subtract on both sides). -2y=0. The answer: (k,0). For the second part, get all the parts of the equations on both sides; (make both sides equal zero) 3x-4y-7 and 3x+2y+5. Then subtract. 3x-4y-7-(3x+2y+5) Make it equal to zero again and solve! :) -6y-12=0 -6y=12!! ta da!
Answer:
zero (0)
when the exponent 0 is applied to a nonzero base, the result is always 1
Step-by-step explanation:
Acoording to the zero power rule, a non zero number raised to the power 0 is always 1:
whit
Let's check this property using an example:
We know that a quantity over itself is always 1:
We also know that a base without exponent is always raised to the power 1:
Now, according to the division power rule , so
Answer:
see below
Step-by-step explanation:
An exponential term with a base greater than 1 will increase at an increasing rate. If the base is less than 1 (a fraction), then it will decrease at a decreasing rate.
Any (non-zero) base to the 0 power will have a value of 1, so the function will have a y-intercept at (0, 1) if there is no multiplier (vertical scale factor) of the exponential factor. The y-intercept will be the value of the multiplier.
