AURORKA [14]4 years ago
5 0

Answer:

  1. <43, -30>
  2. <-1, 6>

Step-by-step explanation:

The answer is found by carrying out the indicated arithmetic. Multiplying a vector by a scalar multiplies each of the vector's components. Adding vectors adds corresponding components.

<u>Question 1</u>

  3u -5v = 3<11, -5> -5<-2, 3>

  = <3·11 -5(-2), 3(-5) -5(3)>

  = <33 +10, -15 -15>

  = <43 -30>

<u>Question 2</u>

  m - n = <0, 0> -<1, -6>

  = <0 -1, 0 -(-6)>

  = <-1, 6>

Answer:

(7x-1)(x-3)

Step-by-step explanation:

7x^2 - 22x + 3

The factors have to add to -22, but multiply to equal 3. But since the "a" value has a number on it, you have to use it too.

(7x +/- [n1]) ( x +/- [n2]) = 7x^2 - 22x + 3

Since the two numbers multiply to a positive value, they have to have the same sign. (7x-1) (x-3) works to produce the expression when it's foiled.

5) The school that Lexy goes to is selling tickets to the annual talent show. On the first day
Juli2301 [7.4K]

Answer:

Adult ticket is $6

Student ticket is $4, as you said.

Step-by-step explanation:

We'll call adult tickets x and student tix y.

14x + 11y = 128

14x + y = 88

First, solve the second equation for y in terms of x:

y = 88- 14x

Then substitute that for y into the first equation:

14x + 11(88-14x) = 128

14x + 968 - 154x = 128

-140x = -840

x = 6  The adult ticket is $6, like you said.

Now take that and solve for y:

y = 88 - 14(6)

y = 88 - 84

y = 4 The student ticket is $4, as you said.

Hope this helps. Feel free to ask questions so you can understand.
