If x=8 and y=−3, evaluate the following expression:6x−8y

Answers

Answer 1

Answer:

Step-by-step explanation:

here's your solution

=> x= 8

=> y= -3

=> putting the value

=> 8*6 - (8*-3)

=> 48 + 24

=> 72

hope it helps

Answer 2

Hey there!

If x = 8 and y = -3, then SUBSTITUTE it into the equation

6(8) - 8(-3)

6(8) = 48

48 - 8(-3)

8(-3) = -24

48 - (-24)

- & - = +

48 + 24 = 72

Answer: 72

Good luck on your assignment and enjoy your day!

You go to the store to buy a Playstation 5 which cost 499 dollars. If you had to
pay San Jose's sales tax which is 9.25%. How would you solve the problem to find
the total cost? *

What is the total cost?*

Answers

Answer:

$545.1575

Step-by-step explanation:

Given function:

499,9.25

Solve ways:

combine 9.25% of 499 and 499

Multiply 9.25 by 0.01:

[tex]9.25%[/tex]·[tex]0.01=0.0925[/tex]

Multiply the cost by 0.0925:

[tex]499[/tex]·[tex]0.0925= 46.1575[/tex]

Combine 46.1575 by the first value:

[tex]499+ 46.1575= 545.1575[/tex]

Therefore, the PlayStation 5 will be a total cost of $545.1575.

Answer:

y = 2x - [tex]\frac{3}{4}[/tex]

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 2 and c = - [tex]\frac{3}{4}[/tex] , then

y = 2x - [tex]\frac{3}{4}[/tex] ← equation of line

Answer: [tex]y=2x-\frac{3}{4}[/tex]

Step-by-step explanation:

We are going to have to put this into slope-intercept form

"y=mx+b"

m=slope

b=y-intercept

slope=2

y-intercept= [tex]-\frac{3}{4}[/tex]

Now we can put it all together, and remember the will always stay in the equation as it does not stand for anything.

[tex]y=2x-\frac{3}{4}[/tex]

Answer:

D. - 5 ≤ x < 1

Step-by-step explanation:

The numerator cannot be the square root of a neg. no.

So, x + 5 ≥ 0 or x ≥ -5

The denominator cannot be a neg. no. or 0.

So, 1 - x > 0

1 > x or x < 1

So, altogether - 5 ≤ x < 1

Therefore, D is the correct answer.

En un estudio estadistico se van a usar unicamente variables cuantitativas discretas para ingresarlas a un programa de analisis estadistico. la variable que se debe ingresar en el programa corresponde a: a nacionalidad b nivel de escolaridad c edad d altura

Answers

Answer:

la variable que se debe ingresar en el programa corresponde a: c. edad

Step-by-step explanation:

Las variables cuantitativas son aquellas que toman valores numéricos y se clasifican en variables cuantitativas discretas que son las que sólo pueden asumir un número limitado de valores en un determinado rango, como por ejemplo, el número de carros que posee una persona y variables cuantitativas continuas que pueden tomar cualquier valor en un rango específico, como por ejemplo, el peso de un objeto. De acuerdo a estas definiciones, la respuesta es que la variable que se debe ingresar en el programa corresponde a: edad porque es una variable discreta dado que se registra en números enteros y no acepta cualquier valor en un intervalo específico.

Las otras opciones no son correctas porque la nacionalidad y el nivel de escolaridad no son variables cuantitativas y la altura es una variable cuantitativa continua.

which is the equation of the line that passes through the points (4,3) and (6,2)

Answers

Answer:

y = -1/2x + 5

Step-by-step explanation:

Find slope:

change in y/change in x

(2-3)/(6-4)

-1/2 = m

Use point-slope form:

y - y1 = m(x - x1)

Where (x1, y1) is a point on the line, let's use (4,3)

y - 3 = -1/2(x - 4)

Point-intercept form:

Expand y - 3 = -1/2(x - 4) to get point-slope form:

y = -1/2x + 5

Hope this helps!! :)
