Answer: ✧･ﾟ: *✧･ﾟ:* No, they are not equivalent. *:･ﾟ✧*:･ﾟ✧

Step-by-step explanation:

♥*♡∞:｡.The first expression is equal to 3x + 24 - 9x, or 24 - 6x, and the second equation equals 6-6x. If you set them equal to eachother, you get 24 - 6x = 6 - 6x. The 6x's cancel out, so you're left with 24 = 6, which is not true. The expressions are not equivalent. ｡.｡:∞♡*♥

In the clip from the Simpsons, Ralph charges Bart twice the fair from Tucson to Flagstaff, minus 2/3 the fair from Albuquerque t

cluponka [151]

Answer:

$20.

Step-by-step explanation:

Given:

In the clip from the Simpsons, Ralph charges Bart twice the fair from Tucson to Flagstaff, minus 2/3 the fair from Albuquerque to El Paso.

It costs $40 to travel from Tucson to Flagstaff,

And $90 to travel from Albuquerque to El Paso.

Question asked:

How much does Bart need to pay ?

Solution:

Fair to travel from Tucson to Flagstaff = $40

Fair to travel from Albuquerque to El Paso = $90

<u>As Ralph charges Bart twice the fair from Tucson to Flagstaff, minus 2/3 the fair from Albuquerque to El Paso. </u>

$Bart\ need\ to\ pay=2 \times\$40 - \frac{2}{3} \times\$90\\ \\$

$=80-\frac{180}{3} \\ \\ =80-60\\ \\ =20$

Thus, Bart need to pay $20.

What is the distance between the points (-4, 2) and (1, -3) on the coordinate plane?

ruslelena [56]

Answer:

A. 7.07 units

Step-by-step explanation:

Use the distance formula for coordinates:

$d=\sqrt{(x_{2}-x_{1})^2 +(y_{2}-y_{1})^2 }$

Fill in the coordinates accordingly:

$d=\sqrt{(1-(-4))^2+(-3-2)^2}$

which simplifies down to

$d=\sqrt{25+25}$

which is of course

$d=\sqrt{50}$

Plug that into your calculator and you'll get the answer

A line passes through the points (9,6) and (6,5). What is its equation in slope-intercept form?

Tju [1.3M]

Answer:

Y=X/3+3

Step-by-step explanation:

M= Y2-Y1/X2-X1

= 5-6/6-9

= -1/-3

= 1/3

sub x=6, y=5, M=1/3 into Y=MX+C

5=6/3+C

5=2+C

5-2= 2+C-2

3=C
