Answer:
1.61 * 10 ^8
3.3 * 10^-7
Step-by-step explanation:
Multiply the numbers and then add the exponents
2.3 * 10^1 * 7 * 10^6
2.3 *7 * 10^(1+6)
16.1 * 10^7
We need to make this scientific notation by moving the decimal one place to the left and adding 1 to the exponent
1.61 * 10 ^8
Multiply the numbers and then add the exponents
1.1* 10^-5 3*10^-2
1.1 *3 * 10^(-5+-2)
3.3 * 10^-7
I believe the answer is 25 because it says that 2)m=5 or it may be 30 because 5times 2 equals 10 and 10plus 20 gives you 30
Answer:
It says “which” so is it multiple choice??
Also a picture would help!!
I’m not quite sure I understand but if your saying that -9 =x and -7 =y then the answer would be -59 so the equation wouldn’t be true I hoped I helped :)
Answer:
Step-by-step explanation:
Let the line 4x-y+k=0
Now 4×(-2)-4+k=0
K=12
So, the line will be 4x -y +12
