Write an equation in slope-intercept form that goes through the points (4, 4) and (1, 2).
Step-by-step explanation:
Hey there!
The given points are; (4,4) and (1,2) as (x1,y1) and (x2,y2).
Note: Use double point formula for the equation.
Now;
[tex](y - y1) = \frac{y2 - y1}{x2 - x1} (x - x1)[/tex]
Put all values.
[tex](y - 4) = \frac{2 - 4}{1 - 4} (x - 4)[/tex]
Simplify it.
[tex](y - 4) = \frac{ - 2}{ - 3} (x - 4)[/tex]
[tex](y - 4) = \frac{2}{3} (x - 4)[/tex]
[tex](y - 4) = \frac{2}{3} x - \frac{2}{3} \times 4[/tex]
[tex]y = \frac{2}{3}x - \frac{8}{3} + 4 [/tex]
[tex]y = \frac{2}{3} x - \frac{8 + 12}{3} [/tex]
[tex]y = \frac{2}{3} x + \frac{4}{3} [/tex]
Therefore, the equation is; y = 2/3x+4/3.
Hope it helps...

Answer:
Multiplying the variables and numbers in the parentheses by the number next to them.
Step-by-step explanation:
2( y+2) = 6x-7
please help
Answer:
2y + 4 = 6x - 7
2y = 6x - 11
2y + 6x = -11
Answer:
2y+4=6x-7
take 4 from both sides
2y=6x-3
divide each side by 2
y=6x-3
i can type 39 words 36 secs at this rate how many words will i type in one minute.
Answer:
65
Step-by-step explanation:
You can write it as a ratio. 39:36. You then have x:60. You can divide 36 by 60 and then divide 39 by that number (0.6)
Answer:
65 words perminute
Step-by-step explanation:
36/ 36=1
39/36= 13/12=1 1/12
1 1/12 x 60=65

12c - 4c + 18 = 50 solving for variable
Answer:
c=4
Step-by-step explanation:
subtract 50-18= 32
then subtract 12c-4c= 8c
8c=32
divide 8c by 32 which gives you
c=4
Answer:
[tex]:\implies \sf 12c - 4c + 18 = 50 \\ \\ \\ [/tex]
[tex]:\implies \sf 8c = 50 - 18 \\ \\ \\ [/tex]
[tex]:\implies \sf 8c = 32 \\ \\ \\ [/tex]
[tex]:\implies \sf c = \frac{32}{8} \\ \\ \\ [/tex]
[tex]:\implies \underline{ \boxed{\textsf { \textbf{c = 4}}}} \\ \\ \\ [/tex]

Can someone please help me on this math chart and graph above I’ve already posted 3 pictures of it and no one is answering :( I’ll mark as brainliest if you answer. Picture is above thank you.
the function is x^2-9, so all you have to do is replace x with a number. for example, 2.
so 2^2-9 is -5. the plot would be 2, -5. basically, plug in a number to be the x coord, and whatever number you get will be your y coord.
after you graph a few plots (doing the same thing above), draw a line through all of them.
if the line goes up towards the right top corner, it's increasing. if it goes down the right bottom corner, it's decreasing.
Find the values of x and y. 3x - 5 5y - 4 y + 12
The values of x and y in the equilateral and Isosceles triangles are 7 and 4 respectively.
What is an equilateral triangle?An equilateral triangle is a triangle that has all its sides equal to each other.
Therefore,
3x - 5 = 5y - 4 (equilateral triangle)
3x - 5y = 1
Therefore,
y + 12 = 3x - 5 (Isosceles triangle)
y - 3x = - 17
Hence,
3x - 5y = 1
- 3x + y = - 17
-4y = -16
y = -16 / -4
y = 4
Therefore,
3x = 1 + 5(4)
3x = 21
x = 21 / 3
x = 7

In an apartment building, there is only one elevator that residents are allowed to use. The elevator picks up six people in the main lobby and ascends 4 floors. Next, the elevator ascends another 2 floors and descends 3 floors. The elevator ascends 8 more floors, then descends 2 floors. The elevator finally descends another 2 floors before getting stuck. What floor is the elevator stuck on?
Answer:
It is stucked on the 9th floor
Step-by-step explanation:
We want to know the floor on which the elevator is stucked.
The main lobby is the ground floor and has a value of 0 floor
Ascends four floors with 6 people from the lobby
It is now on floor 4
Ascends another two so it is now on floor 4 + 2 = 6
Ascends another 2, then descend descends 3
That will be 6 + 2 -3 = 5th floor
Ascends 8 more , then descend 2
That will be 5 + 8 -2 = 11
Descends another 2, making 11 - 2 = 9
It is stucked on floor 9
Kindly note, when it ascends, that is a positive value, when it descends, that is a negative

Step-by-step explanation:
Food bank usage in Britain has grown dramatically over the past decade. The number of users, in thousands, of the largest food bank in year t is estimated to be N(t) = 1.3e0.81t , where t is the number of years since 2006.25
(a) What does the 1.3 represent in this context? Give units.
(b) What is the continuous growth rate of users per year?
(c) What is the annual percent growth rate of users per year?
(d) Using only your answer for part (c), decide if the doubling time is more or less than 1 year.
Answer:
A) 1.3 represents the number of foodbank users in thousands in the year 2006
B) 0.81 per year
C) 124.79%
D) the doubling rate is less than a year.
Step-by-step explanation:
A) We are given N(t) = 1.3e^(0.81t) where t in thousands the number of years since 2006. N(t) is in thousands
Thus, in 2006,t = 0.
So, N(0) = 1.3e^(0.81 × 0)
N(0) = 1.3
Thus,1.3 represents the number of foodbank users in thousands in the year 2006
B) From the question, we see that the continuous growth rate is 0.81t.
This is 0.81 per year
C) The exponent of the growth rate is e^(0.81t).
Thus gives; 2.2479^(t)
This means the annual growth factor for each year is 2.2479.
Thus,annual percent growth rate is;
(2.2479 - 1) × 100% = 124.79%
D) From C above we saw that the annual percent growth rate is more than 100%. This means that it takes less than a year for the number of users to be doubled.. Thus, the doubling rate is less than a year.
Given the functions f(x) = 2x2 +5 and g(x) = 8+x find go f(-5)
A. 63
B.3.
C.2
D.23
Answer:
A. 63
Step-by-step explanation:
Given functions:
f(x) = 2x² + 5
g(x) = 8 + x
find:
g o f(-5)
Solution:
Start first by finding f(-5);
f(x) = 2x² + 5
= 2(-5)² + 5
= 50 + 5
= 55
Now
g o f(-5);
g(55) = 8 + 55 = 63

A juggler throws a beanbag into the air with a speed of 1.0 \dfrac{\text m}{\text s} 1.0 s m 1, point, 0, start fraction, start text, m, end text, divided by, start text, s, end text, end fraction . How long does it take for the beanbag to reach its maximum height?
Answer:
0.102 s
Step-by-step explanation:
Given the following :
Initial speed (u) = 1 m/s
How long does it take the bean bag to reach maximum height?
At maximum height, the final velocity v = 0
Acceleration due to gravity g = - ve (upward motion) =? - 9. 8m/s²
Using the relation:
v = u + gt
0 = 1 - 9.8t
9.8t = 1
t = 1 / 9.8
t = 0.102 s

If on a scale drawing 240 feet
are represented by 10 inches,
then a scale of ¼ inch
represents how many feet?
Answer:
6 feet
Step-by-step explanation:
240 feet : 10 inches
24 feet : 1 inch
? feet : 1/4 inch
to get from 1 to a 1/4 you divide by 4, so you do 24 ÷ 4
24 ÷ 4 = 6
Answer:
6 ft
Step-by-step explanation:
First, make this visually understandable using a ratio:
240 ft = x ft
10 in [tex]\frac{1}{4}[/tex] in
To find the change between the inches,
1/4 ÷ 10 = 0.025
Use this same amount to find x ft:
240 (0.025) = 6
x = 6 ft
To double-check:
240/10 = 24
6/0.25 = 24

Step-by-step explanation:
15. -2.3(8.6)²+ 3.5(8.6)= -140.008
16.
15q + 4j = 17
4j = 17 - 15q

17.
15q + 4j = 17
15q = 17 - 4j
