Filipa is writing an article for a magazine. She will be paid a flat fee and also will be paid for each word that is published. The total amount she can expect to be paid, in dollars, can be estimated using the function f(x)=1.5x + 20, where x is the number of words published. How many words can Filipa need to write to receive $1100

720 words

Step-by-step explanation:

From the question, we are given the function

f(x)=1.5x + 20

When f(x) = Cost function or the cost

From the question, f(x) = $1100

1100 = 1.5x + 20

1100 - 20 = 1.5x

1080 = 1.5x

x = 1080/1.5

x = 720

Therefore, Filipa has to write 720 words

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
