Answer:
---------
Step-by-step explanation:
x-3= -9
x= -9/ 3
x= -3
( -3x)-5 =16
-3x = 16+5
×= 21/-3
x = -7
Answer:
140 cm
Step-by-step explanation:
Given that:
Total length of ribbon present with Billy = 2.4 m
This ribbon is to be shared with 12 friends evenly.
Billy is doing this work of making craft for the past many years.
To find:
How many centimeters of ribbon that 7 friends will get?
Solution:
First of all, let us find out what length of ribbon will each person get.
Length of ribbon to be shared with each person = Total length of ribbon divided by total number of persons
Length of ribbon to be shared with each person = 
Now, The length of ribbon that 7 friends will get = 7 
0.2 = 1.4 m
1 m = 100 cm
1.4 m = 1.4 100 cm = <em>140 cm</em>
If I’m doing it correctly it’s 2/3 but I haven’t done it in a while
Simply substitute x for -3 and y for -5, creating the equation shown below:
-6 (-3 - 2(-5) )
Now that you have your values set up, now you can do the math by starting off with Multiplying -2 by -5, which will get you 10.
Now that you have the parenthesis simplified in the parenthesis, you can use the distributive property by multiplying all the numbers with -6, like so:
-6(-3+10)= 18 - 60, which simplifies to -42, in which (A) is your answer.
Answer:
So if y=-4x+2 was changed to y=-4x+5, then the y-intercept would increase by 3.
The y-intercept was (0,2) then it becomes (0,5) in the new line.
Step-by-step explanation:
The slope-intercept form a line is y=mx+b where m is the slope and the y-intercept is b.
Both of these equations given are in this form.
y=-4x+2 when compared to y=mx+b you see that m=-4 and b=2.
Since b=2 then the y-intercept is 2.
y=-4x+5 when compared to y=mx+b you see that m=-4 and b=5.
Since b=5 then the y-intercept is 5.
So if y=-4x+2 was changed to y=-4x+5, then the y-intercept would increase by 3.
