Answer:

x=5 and y=7

Step-by-step explanation:

The opposite parallel sides of any rhombus are going to be equal.

a.) Knowing this you take (x+14) and make it equal to (5x-2). Then you subtract the x from (x+14), and add the 2 from (5x+2), making the new equation 16=4x. You divide 4 by x and by 16, getting the final simplified answer of x=4.

b.) Using the same method you take 3y-3 and set it equal to (2y+4). Then you subtract the 2y from (2y+4) and add the 3 from (3y-3) to bother sides. Now you have your new equation and answer being y=7.

a.) x+14 = 5x-2

b.) 3y-3 = 2y+4

Which of the following is written as a rational function

sertanlavr [38]

Answer

B. F(x)= x-3/8x

Step-by-step explanation:

A rational function is a function that is a fraction and contains a property that both its numerator and denominator are polynomials.

This is to say F(x) is a rational function if R(x)=p(x)/q(x) where p(x) and q(x) are both polynomials

A polynomial is an algebraic expression which consists of one, two or more terms.

Trying to solve a exponential function question. Evaluate the function when t=5.

Gemiola [76]

If t=5 then all you do is plug that into the function:
h(t)=175(1028)5
You would start by multiplying 1028 by 5 which leaves you with 5140, now plug that into the function.
h(t)=175(5140)
multiply 175 and 5140
h(t)=899500

PLZ HELP ME, THIS IS URGENT! I’m completely lost... :(

Leno4ka [110]

Let’s solve this step by step. :)

First, let’s assign variables for the missing number: x and y.

so the 3 numbers would be x, y and 28

then we have 3 scenarios:
28 + x = 61
28 + y = 76
x + y = 81

Using the first equation, we can get x = 61-28 = 33

Using the 2nd equation, we can get y = 76-28 = 48

then, we can verify if our answer is right by substituting these values in the 3rd equation:

x + y = 81
33 + 48 = 81
81 = 81 ✔️

So the 3 numbers are 28, 33 and 48.

The base of each triangle measures 2 centimeters and the perimeter of each triangle is 10 centimeters. What is the approximate t

tia_tia [17]

Since the triangles make up a spinner, the triangles are isosceles.
The base is 2 cm and the perimeter is 10 cm.
The measure of the two legs can be determined from
2 + 2x = 10
Where is the length of the leg
Solving for x
x = 4
The area an isosceles is calculated using
$A = \frac{1}{2} b^{2} \sqrt{ \frac{ b^{2} }{ x^{2} }- \frac{1}{4} }$
where b is the length of the base
Substitute the values and multiply with the number of triangles in the spinner
