Mathematics
1 answer:
Tcecarenko [31]3 years ago
4 0

Answer:

x is less than or equal to -2

This means anything equal to or less than -2 is the solution to the ORIGINAL equation. Based on the solution set the answer is -3

Step-by-step explanation:

-3x+8 is greater than or equal to 14

    -8                                               -8

-3x is greater than or equal to 6

-3x/-3                                         6/-3

*THIS WILL CAUSE US TO FLIP THE INEQUALITY SYMBOL AS WE DIVIDED BY A NEGATIVE NUMBER

x is less than or equal to -2

This means anything equal to or less than -2 is the solution to the ORIGINAL equation

Based on the solution set the answer is -3

Hope this helps!

Which gives the best estimate and the exact product of (5.9)(8.28)? A: estimate: 40; exact product: 48.852
Evgesh-ka [11]
I think B gives the best estimate and exact product because

1). 5.9 x 8.28 is very similar to 6 x 8 which equals 48.

and 

2. 5.9 x 8.28 = 48.852.

Hopefully that made sense. :)

Consider the multivariable function f\left(x,y,z\right)=\frac{x^3-2.5y^2+\frac{z}{2}}{z\left(x-y\right)}f ( x , y , z ) = x 3 −
Lelu [443]

Answer:

f\left(2,3,1\right)=\bold{14}

Step-by-step explanation:

Given the function:

f\left(x,y,z\right)=\frac{x^3-2.5y^2+\frac{z}{2}}{z\left(x-y\right)}

To find:

The value of f(2, 3, 1) = ?

Solution:

f(2, 3, 1) means the values of x, y\ and\ z as:

x=2\\y=3\\z=1

Let us put the given values in the given function and let us solve for it:

\Rightarrow f\left(2,3,1\right)=\dfrac{2^3-2.5\times 3^2+\frac{1}{2}}{1\left(2-3\right)}\\\\\Rightarrow f\left(2,3,1\right)=\dfrac{8-2.5\times 9+0.5}{1\left(-1\right)}\\\\\Rightarrow f\left(2,3,1\right)=\dfrac{8-22.5+0.5}{-1}\\\\\Rightarrow f\left(2,3,1\right)=\dfrac{-14}{-1}\\\\\Rightarrow f\left(2,3,1\right)=\bold{14}

Therefore, the answer is:

f\left(2,3,1\right)=\bold{14}
