Answer:

B

Step-by-step explanation

f(x)=x2-4x-5

Becomes

f(x)=x2-5x+x-5

Take out the common factor

f(x)=(x-5)(x+1)

Equate the given function equal to 0

0=(x-5)(x+1)

And then

x-5=0 -- x=5

x+1 = 0 == x=-1

Answer:

B

Step-by-step explanation:

we are given a quadratic function

we want to figure out the form which we don't need change

so according to the question

\displaystyle{x}^{2}  - 4x - 5 = 0

rewrite -4x as x-5x:

\displaystyle{x}^{2}   + x - 5x- 5 = 0

factor out x:

\displaystyle \: x({x}^{}   + 1)- 5x- 5 = 0

factor out -5:

\displaystyle \: x({x}^{}   + 1)- 5(x  + 1  )= 0

group:

\displaystyle \: (x  + 1  )(x - 5)= 0

hence our answer is B

On Saturday, you bowl at Mar vista Bowl, where renting shoes costs $2 and each game bowled is $3.50. On Sunday, you bowl at Pinz
7nadin3 [17]

Answer:

  • 12 games

Step-by-step explanation:

Let the number of games is g

<u>Total cost at Mar Vista:</u>

  • 3.5g + 2

<u>Total cost at Pinz:</u>

  • 3.25g + 5

<u>Since same amount spent in both places, we have:</u>

  • 3.5g + 2 = 3.25g + 5
  • 3.5g - 3.25 = 5 - 2
  • 0.25g = 3
  • g = 3/0.25
  • g = 12

What is the value of 5 in 756
BartSMP [9]
7: has a value of 7 hundreds (or 700)
5: has a value of 5 tens (or 50)
6: has a value of 6 ones (or 6)

5 has a value of 50 or five tens

I believe you would draw this by drawing something that looks like place value blocks. I have attached an example of that. In the ones column, you will have 6 single blocks
