Answer:

32 degrees.

Step-by-step explanation:

So every triangle =180 degrees.

Firstly, 14 + 45 = 59

Secondly, 180 - 59 = 121

so angle AEB = 121 degrees.

Using vertical angles theorum, angles AEB and CED are equal to each other

so CED = 121 degrees.

121 + 27 = 148

then 180 - 148 = 32

Angle D = 32 degrees

(might want to fact check this I am pretty tired

Solve the equation (2^2x)/( 2^x+5) = 1 algebraically using two different initial steps as directed below.

NikAS [45]

Answer:

x = 5

Step-by-step explanation:

Given equation as:

$\frac{2^2x}{2^{x+5}}$ = 1

now,

writing each side as power of 2

2⁰ = 1

therefore,

$\frac{2^2x}{2^{x+5}}$ = 2⁰

also, we know the property that , when the number having the same bases gets divided , the powers of the number gets subtracted

therefore,

$2^{2x-(x+5)}$ = 2⁰

now for the equality the power of 2 both sides should be equal

thus,

⇒ 2x-(x+5) = 0

⇒ 2x = x + 5

⇒ 2x - x = 5

⇒ x = 5

Write the equation using function notation f(x). then find f(0)<br><br> 2x^2 - 3y = 6

Grace [21]

$\quad \huge \quad \quad \boxed{ \tt \:Answer }$

$\qquad \tt \rightarrow \: f(0) = -2$

____________________________________

$\large \tt Solution \: :$

$\qquad \tt \rightarrow \: 2 {x}^{2} - 3y = 6$

$\qquad \tt \rightarrow \: 3y + 6 = 2 {x}^{2}$

$\qquad \tt \rightarrow \: 3y = 2 {x}^{2} - 6$

$\qquad \tt \rightarrow \: y = \cfrac{2 {x}^{2} - 6 }{3}$

$\qquad \tt \rightarrow \: y = \cfrac{2 {}^{} }{3} {x}^{2} - 2$

[ here, y can be replaced with f(x) because y is a function of x ]

$\qquad \tt \rightarrow \: f(x) = \cfrac{2 {}^{} }{3} {x}^{2} - 2$

$\large\textsf{Find f(0):}$

$\qquad \tt \rightarrow \: f(0) = \cfrac{2 {}^{} }{3} {(0)}^{2} - 2$

$\qquad \tt \rightarrow \: f(0) = 0 - 2$

$\qquad \tt \rightarrow \: f(0) = - 2$
