1. Alicia and Jamal completed the following proof:
Given: 3x + 7 = x-5
Prove: x=-6
Alicia's Method:
Statements IT Reasons
3x+ 7 - x-5 given
2x+7--5 Subtraction Property of Equality
X -- 12 Subtraction Property of Equality
x = -6 Division Property of Equality
Jamal's Method:
Jamalle Method
Statements Reasons ITIN
3x + 7 - x - 5 given
Subtraction Property of Equality
--2x Addition Property of Equality
-6 = * Division Property of Equality

Who completed the proof correctly?

f(x)=4

step-by-step explanation:

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.

t= 1/3.

hope this .
