agasfer [191]4 years ago
3 0

Answer:

No Solution.

Step-by-step explanation:

16-2t=t+9+4t*16-2t=t+9+4t

16-2t=t+9+64t-2t=5t+9

16-2t=9+63t=5t+9

16-2t-63t=9=5t+9

16-65t=9=5t+9

16-65t=9,

65t=16-9

t=7/65

9=5t+9

5t=9-9

5t=0

t=0/5

t=0

2(x+4)=1/2(4x-4) answer and show work
taurus [48]

2(x+4) = 1/2(4x-4)

Multiply through by 2:-

4(x + 4) = 4x - 4

4x + 16 = 4x - 4

4x - 4x = -4 - 16

0 = -20

This is obviously wrong so there is NO Solution (answer).

area of a triangle is 14x^5 + 63x^2. If the base is 7x^2, write an expression to represent the height ( x^2 means x square)
mr_godi [17]

Answer:

h=4x^3+18

Step-by-step explanation:

Given that,

The area of a triangle, A=14x^5 + 63x^2

Base, b=7x^2

We need to find the height of the triangle.

The formula for the area of the triangle is given by :

A=\dfrac{1}{2}\times b\times h\\\\\text{h is height}\\\\h=\dfrac{2A}{b}\\\\h=\dfrac{2\times (14x^5 + 63x^2)}{7x^2}\\\\h=\dfrac{2\times 7x^2(2x^3 + 9)}{7x^2}\\\\h=2(2x^3+9)\\\\=4x^3+18

So, the height of the triangle is 4x^3+18.

oee [108]

Answer: (a−c)(b−c)>0

Step-by-step explanation:

ab>1 and ac<01. a>0 if c<0 and also b>02. a<0 if c>0 and also b<0

how i did it:

At the vert first, write the inequality as an equation.

Solve the provided equation for one or more values.

Now, display all the values obtained in the number line.

Use open circles to show the excluded values on the number line.

Find the interim.

At the moment, take any random value from the interval and substitute it in the inequality equation to check whether the values reassure the inequality equation.

Intervals that reassure the inequality equation are the solutions of the given inequality equation.
