what are the x and y intercepts for this equation y=−1/4x+2?
(_,_)
Answer:
(8, 0) is the x-intercept
(0, 2) is the y-intercept
Step-by-step explanation:
The y-intercept = 2 since the equation is in slope-intercept form.
The x-intercept occurs when y = 0
So, 0 = -1/4x + 2
0 = -x + 8
x = 8
(8, 0) is the x-intercept
(0, 2) is the y-intercept
In a lab, 700 cells are present at the beginning of an experiment. During the first 7 hours,
the number of cells increased by 12% each hour.
Estimate the time when the number of cells is 1735.
Round answer to nearest whole hour.
Answer:
2 hours
Step-by-step explanation:
1=700
x=1735
1735=700x
1735/700
x=2.47
Answer:
Step-by-step explanation:
This is an exponential equation of the form, A=ar^t, where a is the initial amount and r is the common ratio or rate of growth and t is time. In this case.
A=700(1.12)^t and we want to find when A=1735
1735=700(1.12)^t
1735/700=1.12^t
ln(1735/700)=t(ln(1.12))
t=(ln(1735/700))/(ln(1.12))
t=8 hours
I'm writing an essay about the negative affects school can have on your mental health and life, so if you want tell in the answers
-thanks!
Answer:
Hi! I hope this helps a bit because I'm just gonna give a few things you can talk about...I'm not writing a whole essay lol...
School impacts us in an extremely large variety of ways. Personally, I think it has more negative effects than positive. For example, at a school environment, there are so many ways to get exposed to profanity by your peers. There are definitely ways to be engaged with people who impact your entire life because of swearing. Similarly, students can learn and get very involved in having horrible behavior. Last but not least, I know that bullying is a huge problem at school. Even if it's being done unintentionally, students can really harm both the physical and mental strength of others.
I hope this helps you out...have a great day ❤

D 62.5%
i will mark brainliest
Given:
Last year 80 students signed up for a summer trip to Washington, D.C.
This summer 50 students have signed up to go.
To find:
The percent decrease in the number of students.
Solution:
We have,
Students in last year = 80
Students in this year = 50
Now,
[tex]\text{Decrease}\%=\dfrac{\text{Students in last year - Students in this year }}{\text{Students in last year }}\times 100[/tex]
[tex]\text{Decrease}\%=\dfrac{80-50}{80}\times 100[/tex]
[tex]\text{Decrease}\%=\dfrac{30}{80}\times 100[/tex]
[tex]\text{Decrease}\%=\dfrac{3}{8}\times 100[/tex]
[tex]\text{Decrease}\%=37.5[/tex]
Therefore, the correct option is B.

Anthony bought an 8-foot board. He cut off 3/4 of the board to build a shelf, and gave 1/3 of the rest to his brother for an art project. How many inches was the piece Anthony gave to his brother.
Answer:
8 inches
Step-by-step explanation:
Anthony bought an 8-foot board. He cut off 3/4 of the board to build a shelf
Step 1
The amount of board he used to build the shelf is calculated as:
= 3/4 of 8 foot board
= 3/4 × 8 foot
= 6 foot board.
Step 2
The amount of board left after building the shelf = The rest =
8 foot - 6 foot
= 2 foot
Step 3
We are told that he gave 1/3 of the rest to his brother for an art project
The amount of board he give his brother for an art project =
1/3 × 2 foot
= 2/3 foot
Step 4
How many inches was the piece Anthony gave to his brother?
We convert 2/3 foot to inches
1 foot = 12 inches
2/3 foot = x inches
Cross Multiply
x inches = 2/3 foot × 12 inches
x inches = 8 inches
Therefore, Anthony gave his brother 8 inches of board.

A rectangular garden has an area of 60 squared feet. The garden is 4 feet longer than it is wide. Which equation can be used to determine the length and width of the garden?
Answer: See explanation
Step-by-step explanation:
Let the width be x
Then, the length will be x+4
Area = Length × Width
Therefore,
x × (x+4) = 60
x² + 4x = 60
x² + 4x - 60 = 0
x² + 10x - 6x - 60 = 0
x(x + 10) - 6(x + 10) = 0
(x - 6)(x + 10) = 0
x - 6 = 0
x = 6
The width is 6feet
Length = 6+4 = 10 feet
