Write the equation of the line that passes through the points (-3, 4) and (-3,3)
Answer:
first determine the gradient because the equation of a straight line is y=mx+c
therefore gradient=change in y/change in x
=y2-y1/x2-x1
=4-3/-3-(-3)
=1/0
there fore gradient of the line is undefined
y=x+c
4=-3+c
4+3=c
7=c
therefore y=x+7
4. Solve the system using substitution.
x + 2y = -1
y = -3x - 8

Answer:
4 times, he bought dinner 4 times
Step-by-step explanation:
if kevin get paid for 3 hours, then you would multiply $14 by 3. you would end up with $42, then the weekly allowance is $21. then by adding $21 to the $42 we have you would get $63. then a bus ride costs $2.50 and since he rode it 6 times you would multiply $2.50 by 6, which would equal $15. Then subtracting $15 from the $63, you would end up with $48, and then by dividing the total amount for the dinner each time bought, so $12/$48 would equal to 4 times.

Old Faithful in Yellowstone National Park has a predictable eruption time. The park
rangers use a formula that takes into account the length of the previous eruption and
has proven to be accurate to plus or minus 10 minutes for 90% of the time.
a.
what is the eruption interval?
b what does 90% of the time mean
Answer:How often does Old Faithful blow?
The world's most famous geyser, Old Faithful in Yellowstone, currently erupts around 20 times a day. These eruptions are predicted with a 90 percent confidence rate, within a 10 minute variation, based on the duration and height of the previous eruption.
Step-by-step explanation:

Use a unit multiplier to convert
$12.00 per hour to dollars per
minute.
Answer:
$00.20 per min
Step-by-step explanation:
Technically $12.00 per hour is $12.00 per 60 min. So now take that and divide $12.00 by 60 and you get 20 cents per min.
Answer:
0.2$ per min
Step-by-step explanation:
The number of hours per week that the television is turned on is determined for each family in a sample. The mean of the data is 31 hours and the median is 27.2 hours. Twenty-four of the families in the sample turned on the television for 16 hours or less for the week. The 7th percentile of the data is 16 hours.
Step 1 of 5: Based on the given information, determine if the following statement is true or false. The 54th percentile is less than 26 hours.
Step 2 of 5: Approximately how many families are in the sample? Round your answer to the nearest integer.
Step 3 of 5: Based on the given information, determine if the following statement is true or false. Approximately 200 families turned on their televisions for less than 35 hours.
Step 4 of 5: What is the value of the 50th percentile?
Step 5 of 5: Based on the given information, determine if the following statement is true or false.The first quartile is greater than or equal to 20 hours.
Answer:
Step-by-step explanation:
The mean of the data is 31 hours and the median of the data 27.2 hours.
24 of the families in the sample turned on the television for less than 16 hours for the week.
The 7th percentile = 16 hours
Step 1:
The median is a value that divides the whole data into two equal parts. It implies that the median represents the 50th percentile of the data.
Given that the median is 27.2 hours, thus the 54th percentile should be greater than 27.2 hours.
Thus, the given statement is false.
Step 2:
Let assume that N is the total number of families
24 of the families in the sample turned on the television for less than 16 hours for the week.
The 7th percentile = 16 hours
It means that 7% of N = 24
N = 24/0.07
N = 343
Step 3:
From (2), N = 343
Given that median= 27.2 hours.
It means 200 families turned on their television for less than 27.2 hours.
We don't know if this is true for 35 hours. 100 families may use less than 35 hours and 200 may use more than 35 or vice versa. In addition to that, even 50 families might use less than 35 and 350 may use more than 35 hours.
Hence, the statement is false.
Step 4:
The median is the 50th percentile value which is = 27.2 hours
Step 5:
The statement is false
The 25th percentile is the first quarter of the data and if the 7th percentile is 16 hours, then the 25th percentile should be greater than that.

Steve already has 5 flowers in his garden, and he can also grow 1 flower with every seed packet he uses. Write an equation that shows the relationship between the number of seed packets x and the total number of flowers y.
Answer:
y = x + 5
Step-by-step explanation:
Using the information provided we can create the following equation. Since every seed packet can grow 1 single flower we would need to multiply 1 by the number of seed packets (x), which simplified would be just x . Next we are told that Steve already has 5 flowers in his possession meaning we need to add this to the new flowers that he is growing to get the total number of flowers.
y = x + 5

Answer:
1. 5 + (-2), 5 - 2, and 3
2. 7 + 2
Step-by-step explanation:
1. If we look at the model, there are 5 positive circles and 2 negative circles. This means that we can write it in :-
5 + (-2) 5 - 23 --> *5 - 2 = 3*2. It asked for an equivalent to 7 - (-2). Remember that negative and negative would be positive. So, it would become 7 + 2.
I would appreciate if you give me the brainlist or not. Hope this helps and stay safe, happy, and healthy, thank you :) !!

Adrianna has a garden where she measured the height of a sunflower plant. on the first day it was 1.25 m tall, after 2 weeks it grew by 0.32 m
WHAT IS THE HEIGHT OF THE SUNFLOWER PLANT?
pls answer will give brainlist
Answer:
The height of the sunflower plant is 1.57 meters.
Step-by-step explanation:
Initially, the height of the sunflower plant was of 1.25 m.
Then, it grew by 0.32 m, that is, we have to add 0.32 m to the height.
Sum of decimals:
Dot below dot, add normally. So
1.25
+0.32
---------
1.57
So
The height of the sunflower plant is 1.57 meters.

After 4 years you have 5300 what is the initial deposit if the account pays 2.5% annual interest compounded continuously
Answer:
Initial deposit P = 4,801 (Approx.)
Step-by-step explanation:
Given:
Amount after 4 year = 5,300
Number of year = 4 year
Rate = 2.5% = 0.025
Find:
Initial deposit
Computation:
A = P[1+r]ⁿ
5,300 = P[1+0.025]⁴
5,300 = P[1.025]⁴
5,300 = P[1.1038]
Initial deposit P = 4,801 (Approx.)
