How do i solve this equation 5x-3y=12 for y

1 answer:

6 0

We have such equation
5x-3y=12 /-5x (subtract 5x both sides)
5x-5x-3y=12-5x
-3y=-5x+12 /:3 divide both sides by 3
-y= $\frac{-5x+12}{3}$ /*(-1) multiply both sides by -1
y=- $\frac{-5x+12}{3}$
y= $\frac{5x-12}{3}$ - its the answer

What is the value of x in the equation 6x +2y=48 when y=3

iren2701 [21]

Answer:

x=7

Step-by-step explanation:

6x +2y=48

Let y=3

6x+2(3) = 48

6x+6 = 48

Subtract 6 from each side

6x+6-6=48-6

6x= 42

Divide by 6

6x/6 = 42/6

x = 7

The base of a rectangle lies on the x-axis, while the upper two vertices lie on the parabola y = 13 − x2. Suppose that the coord

Misha Larkins [42]

Answer:

Area of Rectangle = $26x - 2x^3$

Step-by-step explanation:

Rectangle two vertices lie on x axis ; two vertices lie on parabola $y = 13 - x^2$ .

Supposing coordinates of upper right vertex of rectangle are P = $x , y$

Due to parabola symmetry, width of rectangle is twice the distance horizontal (X) axis distance between Y axis & point P.

Width of rectangle = $2x$

Length of rectangle = $y$ ; $y = 13 - x^2$

Area of Rectangle = Length x Width

= $2x (y)$

= $2x (13 - x^2)$

= $26x - 2x^3$

For the data set table 65, 75, 64, 20, 80, 125. what is the mean of this data set table?

Deffense [45]

Answer:

71.5

Step-by-step explanation:

Mean = Sum of data values/How many data values

65+75+64+20+80+125= 429

There are 6 data values in this data set.

429/6 = 71.5

Mean=71.5
