Mathematics

6 0

Answer:

Step-by-step explanation:

2g + h = 2 --------------(I)

g - h = -5------------(II)

   g = -5 + h

Plugin g = -5 + h in equation (I)

  2(-5 + h) + h = 2              {Distributive property:a(b+c) = a*b +a*c}

(-5)*2 + h *2 + h= 2

-10 + 2h  + h    = 2

             3h = 2 + 10

       3h = 12

         h = 12/3

h = 4

Substitute h= 6 in equation (I)  

2g + 4 = 2

    2g = 2 - 4

    2g = -2

      g = -2/2

g = -1

Determine whether the vectors u and v are parallel, orthogonal, or neither.
kicyunya [14]

Answer:

B.) Orthogonal

Step-by-step explanation:

Two vectors u and v whose dot product is u·v=0 are said to be orthogonal

u = <6, -2>, v = <2, 6>

u·v = u1*v1 + u2*v2

          6*2 + -2 * 6

        =12 -12

         =0

√70 is between which two numbers on the number line?
Leto [7]

Answer:

C) 8 and 9

Step-by-step explanation:

We know that 70 is between two perfect squares.

The square numbers 64 and 81 can help us solve this question.

64<70<81

We take square root to get:

\sqrt{64}  \:  <  \:  \sqrt{70}  <  \sqrt{81}

We simplify this to get:

8 \:  <  \:  \sqrt{70}  \:  <  \: 9

Therefore √70 is between 8 and 9.

The correct option is C.
