Write an equation of a line in slope-intercept form if the slope is ½ and the y-intercept is -2.(A) y = (½)x + 2
(B) x - 2y = -4
(C) y = (½)x - 2
(D) 2y = x + 4

Answers

Answer 1

Answer: I was just learning about this. Okay,
First we need to plug in the values of the slope intercept form y = mx + b. b is the y-intercept so it is -2.

y = mx + -2.

Now lets find the rate of change or mx. the slope is 1/2 so the rate of change is 1/2. Lets plug in the value.

y = 1/2x + -2

The answer is A. Hope this helped!!

In Volleyball , players serve the ball to the opposing team . If the opposing team fails to hit the ball , the services is called an ace . A player's ace average is the number of aces served divided by the number of games played . A certain player has an ace average of 0.3 and has played in 70 games this season . How many aces has the player served ?

Answers

To solve, I would write an equation like this: 0.3=x/70 , where x is the number of aces divided by 70 games and 0.3 is his ace average.

0.3=x/70
x=70x0.3
=21

The player has served 21 aces.

Check:
21/70
=0.3

Final answer:

To find the number of aces the player has served, we can use the formula: Ace Average = Number of Aces / Number of Games Played. Given that the player has an ace average of 0.3 and has played in 70 games this season, the player has served 21 aces.

Explanation:

To find the number of aces the player has served, we can use the formula:

Ace Average = Number of Aces / Number of Games Played

Given that the player has an ace average of 0.3 and has played in 70 games this season, we can set up the following equation:

0.3 = Number of Aces / 70

Multiplying both sides by 70, we get:

21 = Number of Aces

Therefore, the player has served 21 aces this season.

Zina spends 1.5 hours setting up her sewing machine and making one hat. The total amount of time spent making hats can be represented by the sequence below.1.5, 2.25, 3.0, 3.75, ...

Which recursive formula can be used to determine the total amount of time spent making hats based on the total amount of time spent previously?

A. f(n + 1) = f(n) + 1.5
B. f(n + 1) = f(n) + 0.75
C. f(n + 1) = f(n)
D. f(n + 1) = f(n)

Answers

Let

$f(1)=1.5\n f(2)=2.25\n f(3)=3\n f(4)=3.75$

we know that

$f(2)-f(1)=2.25-1.5=0.75\n f(2)=f(1)+0.75\n \n f(3)-f(2)=3-2.25=0.75\n f(3)=f(2)+0.75\n \n f(4)-f(3)=3.75-3=0.75\n f(4)=f(3)+0.75\n \n.\n.\n.\n f(n+1)=f(n)+0.75$
