The differences are that in the first equation it has an x and the other has a 3. The first equation is divided by x+3 while the other is divided by x-2
Y α 1/x
y = k/x Where k is the constant of proportionality.
xy = k Cross Multiplying.
k = xy
Recall y= -8 when x = -9
k = -9 * -8 = 72
Finding y when x = 4.
k = xy
72 = 4y Divide both sides by 4.
y = 72/4 = 18.
y = 18.
Answer:
76
Step-by-step explanation:
N=Novels
M=Months
4N = 1M
?? = 19M
4N × 19M = 76 NM
76 NM ÷ 1M
(cancel M) = 76N
therefore, the number of novels Faleh needs to read in 19 months is 76.
Answer: 3.5 in
Step-by-step explanation
∡DOC=90°
DC=7
OC=5
Using Pytagora equation:
DO=√DC²-OC²
DO=√49-25
DO=2√6
Use Equation for area of triangle:
area of ΔDOC=a*Ha/2
DC=a=7
Ha=x---hight of ΔDOC
Area of ΔDOC=DO*OC/2
2√6*5/2=5√6
5√6=7*x/2
10√6=7*x
x=10/7√6
x=24.5/7
X=3.5 in
I believe the correct answer is 42. Just plug in the number for T in the equation. In this case, it would be 3(14). Which just means 3 X 14. Do the multiplication and you've got your answer! Hope this helped!
