Answer: x=9
Step-by-step explanation:
7x=2x+45
5x=45
x=9
Let f(x)=x3(exponent)+kx2(exponent)+x+5
When f(x) is divided by (x+2) the remainder is =3
This is the remainder theorem
so,f(−2)=−8+4k−2+5=3
4k=3+5=8
k=2
Well the +7 also effects your graph but the coefficient 4 determines the stretch or compression of your graph. A higher coefficient compresses your graph more.
11÷2.21=4.97
Rounded to the nearest tenth is 5.0
To find the ratio of centimeters to meters you need to divide 66 by 33 to get 2.
Then multiply 2727 by 2 to get 5454.
