Answer:

b = 1

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

Since we are already given a table of values and half the equation, we simply need to find y-intercept b:

Plug in a random coordinate to find b.

y = 1/4x + b

2 = 1/4(4) + b

2 = 1 + b

b = 1

y = 1/4x + 1

Answers

Answer: 192,768

The sequence multiples by 4

Answer:

Part1:

[tex] \huge{ \boxed{\bold{ \tt{48 }}}}[/tex]

Part 2:

[tex] \huge{ \boxed{\bold{ \tt{768}}}}[/tex]

Explanation:

As we can see every next number is 4 times greater than The number before it.

proof:

[tex]3 \times 4 = 12[/tex]

Here we have multiplied 3 with 4 than we get our next number ie 12

[tex]12 \times 4 = 48[/tex]

When we again multiplied 12 with 4 than we get next number ie 48.

So next two numbers will surely be as follows:

part 1:

[tex]48 \times 4 = 192✓[/tex]

part 2:

[tex]192 \times 4 = 768✓[/tex]

3. Mr. Hudson's class is taking a field trip. The students must share the $100 cost of
using a school bus. Tickets to the museum cost $8 per student. Mr. Hudson spent
$260. How many students went on the trip?

Answers

Answer:

I believe it's 32.

Step-by-step explanation:

Im assuming the teacher is paying for the students tickets and the students are paying for the bus.

So if the teacher spent 260$ and it costs 8$ per student you must divide.

260 ÷ 8 = 32.5 But you cant have half a person so it must be 32 students.

Answers

The answer is x=-4 because you subject 5 on both sides and than divide -2 both sides and it leaves you with x=-4.

Answer:

The answer is x = - 4

Step-by-step explanation:

- 2x + 5 = 13

1.Subtract 5 from both sides

- 2x + 5 - 5 = 13 - 5

- 2x = 8

2. Divide both sides by - 2

- 2x/- 2 = 8/- 2

x = - 4

Answer:

[tex]\boxed {x = -33}[/tex]

Step-by-step explanation:

Solve for the value of [tex]x[/tex]:

[tex]6 + \frac{x}{3} = -5[/tex]

-Multiply both sides by [tex]3[/tex]:

[tex]3 \times 6 + \frac{x}{3} = -5 \times 3[/tex]

[tex]18 + x = -15[/tex]

-Subtract [tex]18[/tex] to both sides:

[tex]18 - 18 + x = -15 - 18[/tex]

[tex]\boxed {x = -33}[/tex]

Therefore, the value of [tex]x[/tex] is [tex]-33[/tex].

The answer is:

6 + x/3 = -5

X/3 = -5 - 6

X/3 = - 11

X = -11 * 3

What happens to the median of the data set
{10, 2, 8, 9, 5, 2, 6} if the number 12 is added to the data set?
A. The median increases by 2.
B. The median decreases by 1.
C. The median does not change.
D. The median increases by 1.

Answers

Answer: C

Explanation:

The median of the data set increases by 1

What is Median?

The median is the value that's exactly in the middle of a data set when it is ordered. It's a measure of central tendency that separates the lowest 50% from the highest 50% of values. The steps for finding the median differ depending on whether you have an odd or an even number of data points

Arrange the data points from smallest to largest.

If the number of data points is odd, the median is the middle data point in the list.

If the number of data points is even, the median is the average of the two middle data points in the list.

Given data ,

To find the median of the data set {10, 2, 8, 9, 5, 2, 6}, we need to first arrange the data in order from smallest to largest:

2, 2, 5, 6, 8, 9, 10

The median is the middle number, which is 6.

If we add 12 to the data set, the new data set becomes {10, 2, 8, 9, 5, 2, 6, 12}.

We again arrange the data in order:

2, 2, 5, 6, 8, 9, 10, 12

The median is still the middle number, which is now 7 (the average of 6 and 8).

Hence , the median increases by 1

Step-by-step explanation:

1 is alternate to 3 so if 1 is 23 then 3 is also 23 . as you know angles on a straight line add up to 180° and 2 and 3 are angles on a straight line. so subtract 23 from 180 to get 157°
