Answers
Answer:
m = -2
Step-by-step explanation:
Let (x1 , y1 ) = ( 3 , 8) and (x2 , y2 ) = ( 2 , 10)
Now
slope (m)
= y2 - 1 / x2 - x1
= 10 - 8 / 2-3

At janices age she is not only 5 times older than ross, but she is 28 years older than ross. How old is janice?
Answers
Answer:
35 years old
Step-by-step explanation:
Let Janice's age = j.
Let Ross's age = r.
j = 5r
j = r + 28
Set the equations equal to each other.
5r = r + 28
4r = 28
r = 7
j = 5r
j = 5(7)
j = 35
Answer: 35 years old

I think y=-5 , x = 3
Answer:
y = 5/3x - 5
Step-by-step explanation:
Slope = rise / run
The distance between two points is 5 up and 3 right. Hence, 5/3x is the slope.
-5 is where the line crosses the y axis, making it the y-intercept.

Do you have options.
If not I am guessing because the roots sucked the water up distributing it throughout the entire plant making it hydrated and strong to stand.

If the perimeter of square 3 is 36 units and the perimeter of square 2 is 48 units, what is the area of square 1?
Answers
Then, we find the side length of square 2 by dividing it by 4, which is 12.
To find the AREA of square 1, we do a^2+b^2=c^2. This is basically adding up area of square 1 and square 2 to get square 3.
a^2+b^2=c^2
9^2+12^2=c^2
81+144=225
So the area is 225 units.
Answer:
225
Step-by-step explanation:
length of side in square 3 = 36/4
=9
length of side in square 2 = 48/ 4
= 12
using pythagorus theorem you can find side of square 1
take the triangle between 3 and 2
9^2 + 12^2 = length of side 1^2
81 + 144 = l^2
225 = l^2
l = 15
therefore length of side 1 is 15
area of square 1 = 15^15
area = 225 square units
hope this helped

Step-by-step explanation:
2/3x-5=1/6x+3
Multiply on both sides by 6
4x-30=x+18
Change its sign and move the variable to the left hand side
4x-x-30=18
4x-30=x+18
4x-x=18+30
3x=18+30
Add the numbers
3x=48
Divide both sides
x=16

David is saving up money to buy a new car. He had $1,350 saved up 4 months ago, and now has $2,150. He adds the same amount of money each month
Answers
Answer:
David is saving up money to buy a new car. He had $1,350 saved up 4 months ago, and now has $2,150. He adds the same amount of money each month
Step-by-step explanation:
I'm not clear on your actual question, but I'm guessing you want to know how much money he has saved each of the last four months.
2150 - 1350 = $800 saved over the past four months
$800 / 4 months = $200 saved per month

help!!!i need it quick
Answers
Answer:
A linear function is written as:
y = a*x + b
Where a is the slope and b is the y-intercept.
An exponential equation is written as:
y = A*(r)^x
Where A is the initial quantity and r is the rate of growth.
If a and A are both positives, the similar characteristic of both types of functions is that as x increases, then the value of y will also increase. Then both functions are increasing functions.
They are different in how they increase, while a linear function increases at a constant rate, an exponential function increases slow at the beginning and really fast as x increases, as you can see in the image below where we compare the two types of functions, the green one is the linear function, and the blue one is the exponential function.
