So first we need to make all of the denominators the same. To do this we multiply the top and bottom of the fraction. Multiply the top and bottom of 1/2 to get 4/8. then multiply the top and bottom of 3/4 by 2 to get 6/8. then add the numerators: 4+6+7= 17. Your answer is 17/8.

Keep in mind that we are not changing the quantity of the fractions, we are just changing how the whole is divided. Hope this helps (let me know if I confused you and I'll elaborate with a chart)

The two answers are the one selected and the choice |x-5| ≤ 1. The steps to solve the other equation are:
|x-5| ≤ 1
x-5 ≤ 1, x-5 ≥ 0
-(x-5) ≤ 6, x-5 is less than 0
x ≤ 6, x ≥ 5
x ≥ 4, x is less than 5
x ∈ [5,6]
x ∈ [4,5]
4 ≤ x ≤ 6

step:-  1

The bag contains six blue marbles,seven black marbles , four orange marbles

and three green marbles

The total marbles contains in a bag        6+7+4+3=20

Two marbles can be drawn one after one with replacement

The surface of a hill is modeled by z = 100 − 4 x 2 − 2 y 2 . When a group of hikers reach the point (-3,-2,56) it begins to sno
m_a_m_a [10]

Answer:

(-24, -8)

Step-by-step explanation:

Let us recall that when we have a function f

\large f:\mathbb{R}^2\rightarrow \mathbb{R}\\f(x,y)=z

<em>if the gradient of f at a given point (x,y) exists, then the gradient of f at this point (x,y) gives the direction of maximum rate of increasing and minus the gradient of f at this point gives the direction of maximum rate of decreasing</em>. That is

\large \nabla f=(\frac{\partial f}{\partial x},\frac{\partial f}{\partial y})

at the point (x,y) gives the direction of maximum rate of increasing

\large -\nabla f

at the point (x,y) gives the direction of maximum rate of decreasing

In this case we have

\large f(x,y)=100-4x^2-2y^2

and we want to find the direction of fastest speed of decreasing at the point (-3,-2)

\large \nabla f(x,y)=(-8x,-4y) \Rightarrow -\nabla f=(8x,4y)

at the point (-3,-2) minus the gradient equals

\large -\nabla f(-3,-2)=(-24,-8)

hence the vector (-24,-8) points in the direction with the greatest rate of decreasing, and they should start their descent in that direction.
