5/8=x/x+4

8x=5(x+4)=5x+20
8x-5x=20
3x=20
x=20/3
x=6, (6)

5/8=6/y
6*8=5y

How do you (experimentally) find the surface area of a pear?​
Lana71 [14]

Answer:

That's like saying "How do you (hypothetically) write a letter?"

Step-by-step explanation:

But you would probably have to measure the length, height, and width of this experimental pear and go from there.

Then plug your length, width, and height into your surface area formula.

It is also important to know where in the pear you are measuring. The top of the pear will have different measurements than the middle.

If f(x) = -3x + 1, find f(1) - 1
Amiraneli [1.4K]

Answer:

f(1) - 1 = -3

Step-by-step explanation:

Step 1: Find f(1)

f(1) = -3(1) + 1

f(1) = -3 + 1

f(1) = -2

Step 2: Find f(1) - 1

f(1) - 1 = -2 - 1

f(1) - 1 = -3

Find the x- and y- intercepts of the graph of the linear equation 3x-6y=2
bogdanovich [222]

- Put x=0, you would get the y-intercept, so you got one point which would be (0,#)

- Put y=0, you got where the graph would touch\cross\intersect the x-axis, and the other point is (#,0)


to get x-intercept:
y=0:
3x=2 >> x=2/3

to get y-intercept:
x=0:
<span>-6y=2  >>> y = -1/3</span>

Write as an algebraic expression: Five times
Alenkasestr [34]

Given:

The statement is "Five times the difference of the cube of y and the square of x".

To find:

The algebraic expression for the given statement.

Solution:

We know that,

Cube = Power 3

Square = Power 2

Difference = Minus (-)

Times = Multiplication (×)

Now,

Cube of y = y^3

Square of x = x^2

Difference of the cube of y and the square of x = y^3-x^2

Five times the difference of the cube of y and the square of x is:

Required expression = 5(y^3-x^2)

Therefore, the correct option is C. The required algebraic expression for the given statement is 5(y^3-x^2).
