Answer:

Graphing y=1/2x-2 will look like this on the graph

Answer:

Step-by-step explanation:

the 1/2 is a gradient so you go up 1 for every 2 to the right

the -2 is the Y intercept so you start graphing the gradient from -2 on the Y axis

Use the quadratic formula where -15 = a, 7 = b, 23 = c:  [tex]\frac{-b +- \sqrt{b^2 - 4ac}}{2a}[/tex]

Plug in the values: [tex]\frac{-7 +- \sqrt{7^2 - 4(-15)(23)}}{2(-15)}[/tex]

And get: [tex]\frac{-7 +- \sqrt{49 +1380}}{-30}[/tex]

Which simplifies to: [tex]\frac{-7 +- \sqrt{1429}}{-30} = (-7 + 37.8021163)/-30 OR (-7 - 37.8021163)/-30 = 30.8021163/30 OR -44.8021163/30[/tex]

Those are approximately 1 and -1.5

Answer:

10/12 also 5/6

Step-by-step explanation:

Answer:

10/12 or the simplified version 5/6

Step-by-step explanation:

you have to multiply 2/3 by the reciprocal of 4/5 which is 5/4

so you write down 2/3 times 5/4 (just multiply across so it's 2x5 over 3x4)

2x5=10 and 3x4=12

10 is the numerator and 12 is the denominator

simplify if the problem calls for it by dividing the top and bottom numbers by 2

Step-by-step explanation:

Answer:

mean: 3.5

standard deviation: 3

median: 3.5

IQR: 3

Step-by-step explanation:

I mean all you gotta do is look at the table that is shown and since the graph is symmetrical the median and mean would be at the center and the standard deviation is basically how far away most of the data points is going to be from the center and the IQR is easy you get the Q1 and Q3 then subtract then and you get 3. So ya.

Answer:

y = x + 6

Step-by-step explanation:

A line that is perpindicular to y = -x + 20 would be y = x. Now, we have to solve for the y-intercept. Knowing the line must cross through (-4,2) we can solve for the y-intercept using the equation y = x which is just up one over one. Going over 4 units to get to x = 0 means going up 4 units to get to y = 6. Now we know the y-intercept is 6. This means the final equation is y = x +6.

Answer:

  622

Step-by-step explanation:

The n-th term of an arithmetic sequence is given by the formula ...

  an = a1 +d(n -1)

where a1 is the first term (6), and d is the common difference (14-6=8).

Then the 78th term is ...

  a78 = 6 + 8(78 -1) = 6 + 616 = 622

The 78th term is 622.

Answer:

x = 2

Step-by-step explanation:

Equation:

3 - 2x = 2x - 5

Step 1: add 2x on each side

3 = 4x -5

Step 2: Add 5

8 = 4x

Step 3: Divide by 4

x = 2

Answer:

around 28% of americans are obese

Step-by-step explanation:

The relative frequency of obesity according to this poll is 28 percent.

Relative frequency is the ratio of the considered sub group's count to the total count. (so its frequency of the considered sub group relative to the total frequency).

Suppose you've to calculate the joint relative frequency of a certain category out of the given big category.

Then its the ratio of the frequency of that certain category to the total frequency of that big category.

Given According to a recent poll 4060 out of 14500 people in the United States were classified as obese based on their body mass index .

Therefore, the relative frequency of obesity according to this poll is 28 percent.

Answer:

third choice is the answer r is greater than or equal to 46

Answer:

3 days

Step-by-step explanation:

4 1/2 - 3/4 = 3 3/4 - 3/4 = 3 -3/4 = 2 1/4

3 - 1/4 = 2 3/4 - 1/4 = 2 1/2 - 1/4 = 2 1/4

Explanation:

The given arithmetic sequence is of the form

a+d(n-1)

where 'a' is the first term and d is the common difference

In the case of

12+3(n-1)

we have a = 12 as our first term and d = 3 as the common difference. This means we start with 12 and add on 3 to each term to get the next one

12+3 = 15

15+3 = 18

18+3 = 21

21+3 = 24

and so on.

Side note: your teacher asks about the first four terms, but each answer choice lists five terms.

Answer:

x = 5

y = 34

Step-by-step explanation:

Sub y = 8x - 6 into second equation (y = 5x + 9)

8x - 6 = 5x + 9

Rearrange by collecting like terms

8x - 5x = 9 + 6

3x = 15

x = 5

Sub x = 5 into first equation (y = 8x - 6)  

y = (8*5) - 6

y = 40 - 6

y = 34
