8n−7y−12n+5−3y

=8n+−7y+−12n+5+−3y

Combine Like Terms:

=8n+−7y+−12n+5+−3y

=(8n+−12n)+(−7y+−3y)+(5)

=−4n+−10y+5

1/128 = 2^(5x+3) anybody know what x is

Jet001 [13]

Answer:

${2}^{(5x + 3)} = \frac{1}{128} \\ {2}^{(5x + 3)} = \frac{1}{ {2}^{7} } \\ {2}^{(5x + 3)} = {2}^{ (- 7)} \\ 5x + 3 = - 7 \\ 5x = - 7 - 3 \\ 5x = - 10 \\ x = \frac{ - 10}{5} \\ \boxed{x = - 2}$

x = -2 is the right answer.

Find the value of x and the value of y

Anestetic [448]

Answer:

Step-by-step explanation:

Since DE is parallel to AB and intersects the other 2 sides, it divides those sides proportionally, that is

$\frac{BE}{EC}$ = $\frac{AD}{DC}$

Note that AD = 33 - 22 = 11

Substitute values into the ratio

$\frac{x}{16}$ = $\frac{11}{22}$ = $\frac{1}{2}$ ( cross- multiply )

2x = 16 ( divide both sides by 2 )

x = 8

To find y use similar triangles

Δ ABC is similar to Δ DEC, thus ratios of corresponding sides are equal

$\frac{AB}{DE}$ = $\frac{AC}{DC}$ , substitute values

$\frac{18}{y}$ = $\frac{33}{22}$ = $\frac{3}{2}$ ( cross- multiply )

3y = 36 ( divide both sides by 3 )

y = 12

Thus y = 12, x = 8 → A
