The green dotted line goes from left to right so it’s going up which means we’re now gonna take the point 0,-4 and count how many points it goes to the right which is 1 and now we count how many it goes up which is 1 so the slope for the green table is 1,1


Blue: the points going to the right is 1 and the points it’s going up is 3 so the slope is 1,3

Solve the equation.<br> 8 -(x + 5) = 5x - 3
Mandarinka [93]

Answer:

x = 1

Step-by-step explanation:

8 -(x+5) = 5x - 3

-(x+5)  --->   -1 (x +5) = -x - 5

8 - x - 5 = 5x -3            8 - 5 = 3

-x + 3 = 5x - 3

+x         +x

3 = 6x - 3

+3       +3

6 = 6x

/6   /6

<u>x = 1</u>

What is the value of f(7.5) when f(x)=2x+7
Ivan

Hey there!!

Given :

f ( x ) = 2x + 7

Find f ( 7.5 )

Now, we will need to substitute the value of 7.5 in place of x

f(7.5) = 2(7.5) + 7

f(7.5) = 15 + 7

f(7.5) = 22

Hope my answer helps!

A box contains 10 red ribbons and 12 blue ribbons. Once a ribbon is picked, it is not replaced. What is the probability of choos
lora16 [44]
I belive the answer is 1.
This is because out of 22 ribbon there are 10 which are bue so the probability of blue ribbons is 10/22 and probability of red ribbon is 12/22. So your question was the probability of choosing a red ribbon then a blu ribbon. Because of the word "then" , this means it is simply asking you to add their probablity so after adding 10/22 with 12/22 your answer will come to 22/22 which is equal to 1.

Multiply and subtract
WITCHER [35]

Answer:

26x³ - 12x² + 5x + 7

Step-by-step explanation:

  1. (2x³ - 3x + 11) - (3x² + 1) x (4 - 8x)
  2. 2x³ - 3x+11 - (12x² - 24x³ + 4 - 8x)
  3. 2x³ - 3x + 11 - 12x² + 24x³ - 4 + 8x
  4. 26x³ + 5x + 7 - 12x²

= 26x³ - 12x² + 5x + 7
