10^9x5.5
So basically it’s like your just adding the zeros at the end except this preference as opposed to seeing all those zeros so scientists chose this method .
Answer: 19
Step-by-step explanation: 234/9=26. 26-7=19
Answer:
Since each gift cost $9 the constant of proportionality is 9 so the equation is y = 9x.
The part of the quadratic formula that dictates whether the function is factorable or not is B. b^2 - 4ac. This determines the number of real, imaginary, negative and positive roots.
In the equation <span>2x^2 + 7x + 3,
we use the quadratic formula
x = -b +- sqrt (b2 -4ac) /2a = -7 +- </span><span>sqrt (49 -24) /4
the answers are x1 =-0.5 and x2 = -3.</span>
The answer is letter c because it doesnt have a closed circle so it doesnt need a line under the >
