A^4 * a^6
exponent rule : x^y * x^z = x^(y + z)
so, a^4 * a^6 = a^(4 + 6) = a^10
Answer: 0.6
Reason: 3 divide by 5 is 0.6
Answer:
B. 7
Step-by-step explanation:
Count every number less than 70 (count the leaf plot numbers if that helps).
62,62,63,64,54,56,56 = 7 drivers that travel less than 70 mph
Answer:
x = 17 and y = 37
Step-by-step explanation:
Let the numbers be x and y.
y = 3 + 2x
xy = 629
substituting y in the second equation we get
x(3+2x) = 629
3x + 2
= 629
2 + 3x - 629 = 0
Solving a quadratic equation by using its formula:
x = [-3 ±√(9-4(2)(-629)] / 4
x = [-3 ± √5041] / 4
x = [-3 ± 71] / 4
x = 17 and 
Ignore the negative number in x and just use x = 17 in the first equation we get
y = 3 + 2(17) = 37
Step-by-step explanation:
To add integers on the number line, you move forward, and you face right (the positive direction) when you add a positive number. As with positive numbers, to add negative integers on the number line, you move forward, but you face left (the negative direction) when you add a negative number.
