Answer: Interval = [103,∞)
Explanation :
A medicine become ineffective if its temperature ever reaches 103 degrees Fahrenheit or more .
So, Interval becomes [103,∞)
i.e. semi-open or semi-closed interval as it includes 
So, we used closed brackets i.e. square brackets and
For '∞' we always use open brackets only.
2x+30y=12x+17
30y=10x+17
y=(10/30)x+(17/30)
x-intercept:
0=(10/30)x+(17/30)
-17/30=(10/30)x
-17/10=x
Answer:
So, to work with negative exponents you need to multiply like a positive exponent, and move the decimal over double the digits place each time.
Examples:
If it is 4 with an exponent of -2, then you will multiply 4 by 4 to get 16, and then move the decimal over double the amount of digits. There are two digits, so you will move the decimal over four digits.
So the answer to 4 with an exponent of -2 would be .0016.
To find the decimal equivalent:
DIVIDE 5 by 16.
5/16=0.3125

Answer:
23)
P = 20x^2 + 14xy^2
A = 70x^3y^2
24)
P = 8a^3b + 4ab
A = 4a^4b^2
25)
A = 18x^3y
Step-by-step explanation:
23)
P = 2(10x^2 + 7xy^2)
P = 20x^2 + 14xy^2
A = 10x^2 x 7xy^2
A = 70x^3y^2
24)
P = 2a^3b + 6a^3b + 4ab
P = 8a^3b + 4ab
A = 1/2(2a^3b)(4ab)
A = 4 a^4 b^2
25)
A = 1/2(4xy+8xy)(3x^2)
A = 1/2(12xy)(3x^2)
A = 18x^3y
