Answer:

Simplifying

7 + 3lnx = 15

Solving

7 + 3lnx = 15

Solving for variable 'l'.

Move all terms containing l to the left, all other terms to the right.

Add '-7' to each side of the equation.

7 + -7 + 3lnx = 15 + -7

Combine like terms: 7 + -7 = 0

0 + 3lnx = 15 + -7

3lnx = 15 + -7

Combine like terms: 15 + -7 = 8

3lnx = 8

Divide each side by '3nx'.

l = 2.666666667n-1x-1

Simplifying

l = 2.666666667n-1x-1

If a translation of T2, –7(x, y) is applied to ΔABC, what are the coordinates of B'?
NikAS [45]

The coordinates of B' are 3 and -12. so option D is correct (3, -12)

<h3>How to find the coordinates of B'?</h3>

The point P(x, y) may undergo translation to form P' by using a defined translation rule :

If given the rule T(a, b) synch that P undergoes translation on T; then we will have P'(x+a; y+b)

Therefore,

The point B has its coordinates as B(1, - 5)

Translation rule, T(2, - 7) then the coordination of B after undergoing transformation according to T2;

B(1, - 5) - - - > T(2, - 7) - - - - > B'(1+2 ; - 5+-7)

= B'(3, -12)

Hence, the coordinates of B' are 3 and -12. so option D is correct.

How do you solve the equation 1.6y=9
OverLord2011 [107]
9 divided by 1.6 should get you the aswer since you want y to be by itself you have to divide it by 1.6 in order for both of them to cancel each other out and you can't just do it to one side you have to do it the other side so 9 divided by 1.6 equals 5.625
