What is the first step to solve the equation 16x-21 = 52?
Makovka662 [10]

Answer:

2) Add 21 to both sides

Step-by-step explanation:

When solving 16x-21=52 for x, our goal to isolate x such that we have x set equal to something.

Therefore, we want to start by adding 21 to both sides. This leaves us with 16x=73 and we are one step closer to isolating x.

dimulka [17.4K]

Answer:

3.471 + 7.2516 x

Step-by-step explanation:

Given the data:

(1,3) (2,0) (5,-8) (9, -25) .

X:

1

2

5

9

Y:

3

0

-8

-25

The line of best fit for the data given can be obtained using an online regression calculator :

The equation of best fit for the data is thus;

Best fit equation; y = -3.471 + 7.2516x

How do you add vectors? Add the vector 3,4 to the vector that goes 7 units at an angle of 2π/3.
Gekata [30.6K]

The sum of two vectors is (- 0.5, 10.1)

<u>Explanation: </u>

To add two vectors, add the corresponding components.

Let u =⟨u1,u2⟩ and v =⟨v1,v2⟩ be two vectors.

Then, the sum of u and v is the vector

u +v =⟨u1+v1, u2+v2⟩

(b)

Two vectors = ( 3, 4 )

angle 2π/3 = 120°

In x axis, the vector is = 7 cos 120°

                           = 7 X -\frac{1}{2} \\\\= -3.5

In y axis, the vector is = 7 sin 120°

                                  = 7 X 0.866

                                  = 6.062

The second vectors are ( -3.5, 6.062)

Sum of two vectors = [( 3 + (-3.5) ), (4 + 6.062)]

                              = (- 0.5, 10.1)
