Y=0.5x-0.5
( u find the slope using rise/run then after finding the slope u use the equation and a point on the graph to find the y-intercept
Answer:
4
Step-by-step explanation:
duh
60*80%=
60*0.8 = 48
one of your choices should be 48 or something close to 48
Answer:
k = - 3
Step-by-step explanation:
Given that x = 3 is a solution then it satisfies the equation, that is
2(3)² - 5(3) + k = 0
2(9) - 15 + k = 0
18 - 15 + k = 0
3 + k = 0 ( subtract 3 from both sides )
k = - 3
BMI = (pounds * 703) / (height^2)
so in the information you are missing the height
let's find it :)
first plug in what you know:
28.5 = (211 * 703) / (height)^2 then solve for (height)
28.5 (height)^2 = (211 * 703) multiplied both sides by (height)^2
(height)^2 = (211 * 703) / 28.5 divided both sides by 28.5
(height) = square root [(211 * 703) / 28.5] square rooted both sides
(height) = 72.143 inches
The healthy BMI is about 25
so 25 = (pounds)(703) / (72.143^2)
25(72.143^2) / (703) = (pounds) divide by 703, multiply by (72.143^2)
pounds = 185
211 - 185 = 26
Therefore Christopher would have to lose 26 pounds.
*Note: If the BMI you wanted to use was not 25, then just replace it like this
(pounds) = (BMI)(72.143^2) / (703) = goal weight
