Answer:
y = 8x + 3
Step-by-step explanation:
The line we are describing here is line p;
slope of line p = 8
y- intercept = (0,3)
y-intercept of a line is the point where it crosses the y-axis. At this point, the x = 0
So;
Slope of the line = 8
y-intercept = 3
Equation of the line;
y = mx + c
y and x are the coordinates
m is the slope
c is the y-intercept
y = 8x + 3

Answer:
x = 4.25 (A. 4.25)
Step-by-step explanation:
(For, 4x + 39) 4 times 4.25 = 17, then add 17 + 39, which gets you to 56.
( for 16x - 12) multiply 16 times 4.25 = 68. subtract 12 from 68 to equal 56.

Suppose the average temperature for a 4‐day period in Chicago, Illinois, is ‐8Ԭ. After the next day, the 5‐day average is ‐9Ԭ. What was the low temperature for the fifth day? Explain your reasoning by showing your work or writing down your thoughts and answer.
Answer:
-13
Step-by-step explanation:
Given that:
Average temperature for a period of 4 days = - 8
Average temperature for a 5 day period = - 9
Temperature on the 5th day:
(total temp for the 4 days + 5th day temperature) / 5 = - 9
Let 5th day temperature = x
Total temperature for the 4 days = 4 * - 8 = - 32
(-32 + x) / 5 = - 9
-32 + x = - 45
x = - 45 + 32
x = - 13

2x+1<9
I need help with this question
Answer: x<4
Step-by-step explanation: Let's solve your inequality step-by-step.
2x+1<9
Step 1: Subtract 1 from both sides.
2x+1−1<9−1
2x < 8
Step 2: Divide both sides by 2.
2x /2 < 8 /2
x<4

A bricklayer supports a 5 meter ladder. Against a vertical wall. The foot of ther ladder is 3 meters from the wall. Calculate the heigth at which the top of ladder is
Answer:
4 meters
Step-by-step explanation:
Let the height at which the top of the ladder is be represented by h. The sketch of the question forms a right angled triangle. So that applying the Pythagoras rule,
[tex]/hyp/^{2}[/tex] = [tex]/Adj 1/^{2}[/tex] + [tex]/Adj 2/^{2}[/tex]
[tex]5^{2}[/tex] = [tex]h^{2}[/tex] + [tex]3^{2}[/tex]
25 = [tex]h^{2}[/tex] + 9
[tex]h^{2}[/tex] = 25 - 9
= 16
⇒ h = [tex]\sqrt{16}[/tex]
= 4
Therefore, the height at which the top of ladder is placed is 4 meters.

What is the probability that a randomly selected student has a cell phone and is from School B?
(Round to the nearest hundredth)
a. 0.21
b. 0.41
c. 0.62
Answer:
B
Step-by-step explanation:
Because there is 1000 people in total, the percentage of people in the school B with cellphones would be solved by finding 408/1000=.408. If you round .408 to the nearest hundredth, because the thousandth place is 8, it would round up to .41
Answer:
[tex]\huge\boxed{\text{(B)}\ 0.41}[/tex]
Step-by-step explanation:
This table will prove to be helpful to find the probability that a student has a cell phone and is from School B.
First off, we know that a total of 1000 students were interviewed, both from School A and from School B.
We also know that 479 of those 1000 were from School B (total on the right).
Looking further into School B, we can see that 408 students from school B have a cell phone.
Therefore, we can find the probability by finding 408 / 1000.
[tex]408 \div 1000 = 0.408 \approx 0.41[/tex]
Therefore, the probability that a randomly selected student is from School B and has a phone is 0.41, or 41%.
Hope this helped!

Hernando ate 2/8 of a pizza for a dinner. he gave his 6 friends the rest of the pizza, and told them to share equally. To determine the fraction of the whole pizza that each of his friends received, Hernando performed the calculations below.
6/8 divided by 6= (6 divided by 6)/8= 1/8
he concluded that each person received 1/8 of the whole pizza. Are Hernando's calculations correct?
O yes they are correct. Hernando divided 6 by 6
O yes they are correct. Hernando divided 2/8 by 6
O No they are not correct. Hernando should have multiplied by 6, not divided by 6
O No, they are not correct. Hernando should have divided 8 by 6, not 6 by 6.
Answer:
O yes they are correct. Hernando divided 6 by 6
Step-by-step explanation:

In how many ways can the numbers 3,4,5,6,7,8,9, and 10 b
divided into two sets A and B such that the sum of the numbers in B is three times the sum of the numbers in A?
pls help quick! will mark brainliest!
Answer:
4 times
Step-by-step explanation:
Given that the sum of all the numbers => 3+4+5+6+7+8+9+10 = 52
And we are to divide it into two sets such that the sum of set B is three times the number of sum of set A => Sum B = 3 * Sum A
Hence Total sum = Sum B + Sum A
Total sum ÷ 4 = 52 ÷ 4 = 13.
Since Sum B = (3 * Sum A) => (3 * 13 ) = 39
Therefore Sum B = 39 and Sum A = 13
To divide them into two sets
Sum A = (10, 3) = 13: Sum B = ( 4, 5, 6, 7, 8, 9) = 39
Sum A = (9, 4) = 13: Sum B = (3, 5, 6, 7, 8, 10) = 39
Sum A = (8, 5) = 13: Sum B = (3, 4, 6, 7, 9, 10) = 39
Sum A = (7, 6) = 13: Sum B = (3, 4, 5, 8, 9, 10) = 39
Hence, the correct answer is 4 times
What is the slope of the line y=1/8x-1
Answer:
1/8x ... -1 would be the y intercept so 1/8x is the slope
Hello there, hope you are having a splendid day. :)
y=1/8x-1
This equation is written in slope-intercept form, which looks like so:
y=mx+b
Where m is the slope (1/8) and b is the y-intercept (-1).
Hope it helps. Ask me if you have any queries.

Question:
x = a2 + b2/ab+1
Answer:
x = a³b + b²/ab + 1
Step-by-step explanation:
x = a² + b²/ab + 1
x = a² × (ab + 1) + b²/ab + 1
x = a³b + a² + b²/ab + 1
x = a³b + b²/ab + 1
