(25 ) this absolute value equation has bested absolute values. use your knowledge of solving absolute value equations to solve this equation. justify the number of possible solutions.

x = 4

Step-by-step explanation:

Break down the problem into these 2 equations.

(2x + 5) -3 = 10

-(-(2x + 5) -3) = 10

Solve the 1st equation: (2x + 5) -3 = 10

x=4

Solve the 2nd equation: -(-(2x + 5) -3) = 10

x = 1

Collect all solutions.

x = 1, 4

Check solution

When x = 1, the original equation ||2x + 5| -3| = 10∣does not hold true.

We will drop x = 1 from the solution set.

Therefore,

x = 4

is means division by fractions

step-by-step explanation:

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
