When multiplying we ADD the exponents so:-
a^2 * a^k = a^(2+k) = a^6
so 2 + k = 6
making k = 4
Answer:
6,7,8,9,10
Step-by-step explanation:
Answer:
Equation:
Step-by-step explanation:
3y = x + 15
y + 3x = 4
To get the y-value Subtract 3x from both sides.
y = -3x + 4
Then substitute;
3(-3x + 4) = x + 15
Distribute: -9x + 12 = x + 15
Subtract x from both sides
-10x + 12 = 15
Subtract 12 from both sides
-10x = 3
Divide both sides by -10
x = 3/-10
Then to get the value of y;
y = -3(3/-10) + 4
Answer:
Step-by-step explanation:
x-axis and y-axis meet at (0, 0), that is the origin
Answer:
The negative solution = x = -4
Step-by-step explanation:
Let the number be = x
The square of number = x²
The difference between the square of a number and 28 = x²-28
Given that the difference of the square of a number and 28 is equal to three times that number.
Thus, the equation becomes
subtract 3x from both sides
Thus, the negative solution = x = -4
