The sum of adjacent angles is 180°.

(3y -20) +(2y +15) = 180
5y -5 = 180
y -1 = 36
y = 37

Opposite angles are equal.

5x -14 = 2y +15
5x = 2y +29
x = 0.4 y +5.8
x = 0.4*37 +5.8 = 20.6 . . . . . . . selection A is appropriate

Which logarithmic equation is equivalent to the exponential equation below? e^4x = 5 (the x is part of the ^4 exponent) A. log 5

GalinKa [24]

Keep in mind that "ln" is just a shortcut for the logarithm with a base of "e".

$\bf \textit{exponential form of a logarithm}\\\\
log_{{ a}}{{ ( b)}}=y \implies {{ a}}^y={{ b}}\qquad\qquad 
% exponential notation 2nd form
{{ a}}^y={{ b}}\implies log_{{ a}}{{(b)}}=y \\\\
-------------------------------\\\\
e^{4x}=5\implies log_e(5)=4x\implies ln(5)=4x$

Consider the diagram below.<br> Which of the following statements is correct?

Nutka1998 [239]

Answer:

Step-by-step explanation:

The diagram shows two parallel lines XY and WV.

1. Parallel lines XY and WV are cut by transversal XW, then angles YXZ and VWZ are congruent as alternate interior angles.

2. Parallel lines XY and WV are cut by transversal YV, then angles XYZ and WVZ are congruent as alternate interior angles.

AA similarity theorem states if two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar.

So, $\triangle XYZ\sim \triangle WVZ$ by AA similarity
