Which equation is an identity?
3(x – 1) = x + 2(x + 1) + 1
x – 4(x + 1) = –3(x + 1) + 1
2x + 3 = 2 x plus 3 equals StartFraction one-half EndFraction left-parenthesis 4 x plus 2 right-parenthesis plus 2.(4x + 2) + 2

3. What is the slope of 3y - 4x = 12?
Answer: (3,0)
Step-by-step explanation: x=0
3y=12
divide both sides by 3 you get
y=4 now you have y axis ( equation x=0) at the point its (0,4)
but if you put y=0 then you get
4x=12
and then x=3
so i think the answer is (3,0)

What is the equation of this graphed line? If the line passes through (-6,-3) and (6,-7)
Answer:
y= -1/3x - 5
Step-by-step explanation:
Answer:
The answer would be y=-1/3x-7.
Step-by-step explanation:
Using the formula y2-y1/x2-x1 to find the slope of the line, plug in the numbers and you will get a slope of -1/3. Now using the the formula y-y1=m(x-x1) and plug in the numbers, and you will get the equation y=-1/3x-7.
4(a + 2) + 2 = 4 - 2(-2a - 3)
Answer:
0=0
Step-by-step explanation:
4(a + 2) + 2 = 4 - 2(-2a - 3)
4a + 8 + 2 = 4 + 4a + 6
4a + 10 = 10 + 4a
0 = 0
Given a linear equation with a slope of - 13/4, determine the slope of a line that is perpendicular. Enter the answer as a fraction.

1. Un arquitecto construirá una casa de interés social en un área rectangular de 52 m². El
frente será el ancho de la casa y el largo será dos veces el ancho.
a.
Traza una figura geométrica que represente el terreno
b.
¿Cuál es la variable con la que representarías el ancho?
Answer:
Definamos:
A = Ancho
L = Largo.
Sabemos que el área es rectangular, y para un rectángulo de ancho A y largo L, el área es:
Área = A*L.
Y sabemos que L = 2*A.
a) Una imagen se encuentra abajo.
b) Como podemos escribir la variable L en términos de la variable A, podemos escribir:
Área = A*L = A*(2*A) = 2*A^2
Entonces la variable que usamos es el ancho.
Ahora podemos resolver el problema:
52m^2 = 2*A^2
52m^2/2 = 26m^2 = A^2
A = √(26m^2) = 5.1 m
Entonces el largo es:
L = 2*A = 2*5.1m = 10.2 m

Mikaela is competing in a race in which she both runs and rides a bicycle. She runs 4.5 kilometers in 0.5 hour and rides her bicycle 18.75 kilometers in 0.75 hour. If she runs for 1 hour and bikes for 1 hour at the same rates as she does in the race, how far will she travel?
Answer:
25.67 km
Step-by-step explanation:
4.5 + 0.75 + 18.75 - 0.5 - 2 hrs = 25.67km
Answer:
about 35 km
Step-by-step explanation:
4.5 km divided by 0.5hour/30minutes = 6 min, 40 sec per km
18.75 divided by 0.75hour/45 minutes = 2 min 24 sec per km
