Answer:

The slope is 2.5

Step-by-step explanation:

y = 2.5x + 5   or

y =   5/2x + 5

When x=0, y = 5

When y=0, x = -2

Answer:

slope  = 5/2

y = \frac{5}{2}x + 5

Step-by-step explanation:

(x₁ ,y₁) = (-4 , -5)    & (x₂, y₂) = (2 , 10)

Slope=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\\\=\frac{10-[-5]}{2-[-4]}\\\\=\frac{10+5}{2+4}\\\\=\frac{15}{6}\\\\=\frac{5}{2}\\\\= 2.5

m = 5/2 ;  (-4 , -5)

Equation: y - y1 = m(x -x1)

                y - [-5] = \frac{5}{2}*(x - [-4])\\\\y + 5 = \frac{5}{2}(x + 4)\\\\y + 5 =\frac{5}{2}x + \frac{5}{2}*4\\\\y + 5 = \frac{5}{2}x  + 5*2\\\\y + 5 = \frac{5}{2}x + 10\\\\      y = \frac{5}{2}x + 10 - 5\\\\      y = \frac{5}{2}x + 5

Please answer my question, and if you can please provide an explanation so I can learn from it. 50 POINTS.
gayaneshka [121]

Answer: -4x - y = -50 (second option)

Step-by-step explanation: The only way lines won't intersect is if they're parallel. Parallel lines have the same slope --> the line must have a slope of -4x.

Option 1:

  • y = 4x - 200 (add 4x to both sides)
  • <em>Different slope.</em>

Option 2:

  • -y = 4x - 50 (add 4x to both sides)
  • y = -4x + 50 (divide by -1)
  • <em>Same slope.</em>

Option 3:

  • -y = -4x - 200 (subtract 4x from both sides)
  • y = 4x + 200 (divide by -1)
  • <em>Different slope.</em>

Option 4:

  • -y = -4x - 50 (subtract 4x from both sides)
  • y = 4x + 50 (divide by -1)
  • <em>Different slope.</em>

a physician orders aminophylline 7.5 mg per kg of body weight. the patient weighs 110 lb. if aminophylline is available in 0.125
Harman [31]

Answer:

The patient will receive 2 whole tablets.

Step-by-step explanation:

The total weight of the drug to be administered can be expressed as;

Total dose of aminophylline to be administered=Dose per weight of patient×weight of patient

where;

Dose per weight of patient=7.5 mg per kg

weight of patient=110 lb

1 kilogram=2.205 lb

weight of patient in kilograms=110/2.205=49.89 kilograms

replacing;

Total dose of aminophylline to be administered=Dose per weight of patient×weight of patient

Total dose of aminophylline to be administered=(7.5×49.89)=374.175 mg

Total weight of tablets=374.175 mg

Total weight of tablets=weight per tablet×number of tablets

where;

Total weight of tablets=374.175 mg

Weight per tablet=0.125 g

1 gram=1000 mg

Weight per tablet in mg=(1,000×0.125)=125 mg

Number of tablets=n

replacing;

Total weight of tablets=weight per tablet×number of tablets

374.175=125×n

n=374.175/125

n=2.9934

The patient will receive 2 whole tablets.

Basically make a plot that has no correlation (the points are all random and don't mean anything)
