Determine the correct set up for solving the equation using the quadratic formula.
netineya [11]

Answer: B

Begin by simplifying the given equation, so it's rearranged into standard form. Move all the terms onto one side, so they equal 0. This would result with 4x^{2}-3x-9=0. Quadratic formula is (-b±√(b²-4ac))/(2a). Standard form follow this variable format: ax^{2}+bx+c. Use the numbers that correspond with each variable to substitute them into the quadratic formula. This would be

(-(-3)±√(-3²-4(4)(-9)/2(4).

arsen [322]

Answer:

D. 1200 mg

Step-by-step explanation:

In order to find the solution we need to understand that a dosage of 20 mg/kg means that 20 mg are administered to the patient for each kg of his/her weight.

So, if the patient weight is 60 kg then:

Total drug X = (20mg/Kg)*(60Kg)=1200mg.

In conclusion, 1200 mg will be administered to the patient, so the answer is D.

Write the equation of the line perpendicular to y=2/3×-6 that passes through the point (6,4)
mash [69]

the slope of the given line is 2/3.  The slope of a line perpendicular to this given line is the negative reciprocal of 2/3, or -3/2.

The line passes thru (6,4).  We can immediately write the desired equation as follows:

y - 4 = (-3/2)(x-6).  This could, of course, be written differently:

y = 4 - (3/2)x + 9, or    y = (-3/2)x + 9 (in slope-intercept form).
