Answer:
Step-by-step explanation:
That means y= -3x -3 in the y=mx+b form. It means that you will draw a dot at the point (0,-3). Then, M= #of points that you will go up or down (positive=up, negative= down). So, M= -3, negative, so go 3 points down to (0,-6) and go one point to the right. It will give you a point at (0,-3) and at (1,-6). Now, just draw the line and it s=is all done :)
Answer:
I will be answering numbers 3), 4), and 6) (so that you get most of the concept and that you are able to solve the questions by yourself), and also 9).
Step-by-step explanation:
3)
-15/4b+5/6b
So, first find the common denominator of both fractions. 4 times 6 is 24. -15/4b= -90/24b. 5/6b=20/24b. -90/24b+20/24b=-70/24b=-35/24b=-1 11/24.
4)
60m-15(4-8m)+20
What we need to do first is remove the parentheses.
60m-(15*4-15*8m)+20
=60m-60-120m+20.
So, here, we add the numbers without 'm' and the numbers with 'm.' (Always include the sign in front of the number, like in the equation, we include -60 since that's the sign in front of 60.)
60m-60-120m+20
=-60+20=-40
60m-120m=-60m
=-60m-40
6)
9y-15y+12-6y
Like I said before on number 4, we do about the exact same thing (but there are no parentheses to remove, so we skip that step.)
9y-15y+12-6y
=9y-15y-6y
=-12y+12
9)
It is basically the same thing as we did in the previous problems, just in a different way of saying it.
12x+12x+2x+2x+x+9
=28x+9 yards
Answer:
9
Step-by-step explanation:
The length of the paper , x, can be obtained using Pythagoras :
Width = 12 ; length = 15
x² = 15² - 12²
x² = 225 - 144
x² = 81
x = sqrt(81)
x = 9
Hence, length of the paper = 9 inches
Answer:
5/6x + 3 = y
Step-by-step explanation:
The slope intercept form is:
mx + b = y
The slope is 5/6.
The y intercept is 3.
Answer:
The answer is option C
Step-by-step explanation:
sin C = opposite / hypotenuse
the opposite is 40
the Hypotenuse is 50
so
sin C = 40/50 = 4/5
Hope this helps you
