Step-by-step explanation: The sign wouldnt be greater than or equal to because he wants to spend less than 250.
80 percent of needed milligrams is 1360
so
1360/.80 = x/1
1700 milligrams
Use slope formula
(y1-y2)/(x1-x2)
(16 - -19)/(0 - 4) = 35/-4
Exponent multiplication and addition will simplify this expression.
Exponent Addition: a^b * a^c = a^(b + c)
Exponent Multiplication: (a^ d) ^ e = a ^ (d * e)
Multiplication of 4^8 * 4^(-4) is the same as adding exponents together:
4^(8 - 4)
Which makes the expression simplify to (4^4). This expression is now to another exponent which is equivalent to multiplying exponents together:
(4^4)^-2 = 4^ (4 * -2) = 4 ^ -8
The expression has been reduced to its simplest form.
