Answer:
Step-by-step explanation:
I assume the problem is to graph the lines. The easiest is to pick two values of x and calculate y for each line. For example:
21. y = -4x + 5 I'll randomly choose vales of 1 and 2 for x and calculate y:
(1, 1) and (2, -3)
Now mark those two points and draw a straight line through them. It is an equation of a straight line, so we know this will be correct.
22. Same process:
(1,6) and (2,7)
23. (1,0) and (2,-3)
24. (1,-4) and (2,-6)
=====================
These are shown in the attachment. What's also shown is the second method of producing the lines: Use a graphing program such as DESMOS to plot the equations. The points aren't needed - they are there to demonstrate that the first approach also works.
Answer:
2 52/67 (2.77611940...)
Step-by-step explanation:
See how many times 67 goes into 186:
2
Then the remainder is 52/67.
Answer:
0.0726mL
Step-by-step explanation:
Let's find the answer by using the following formula:
(subcutaneous dose)=(milliliters of the injection)*(drug concentration)/(child weight)
Using the given data we have:
(0.01mg/kg)=(milliliters of the injection)*(1mg/mL)/(16lbs)
milliliters of the injection=(0.01mg/kg)*(16lbs)/(1mg/mL)
Notice that the data has different units so:
1kg=2.20462lbs then:
16lbs*(1kg/2.20462lbs)=7.25748kg
Using the above relation we have:
milliliters of the injection=(0.01mg/kg)*(7.25748kg)/(1mg/mL)
milliliters of the injection=0.0726mL
