Answer:
-22
Step-by-step explanation:
f(x) = 5x -7
substitute x = -3 into the equation as follows:
f(-3) = 5( -3) -7
= -15-7
= -22
Hello there!
Answer:
The slope is 9, and the y-intercept is –2
Step-by-step explanation:
The equation is y = 9x - 2
This follows the equation y = mx + b
Where as:
m = slope
b = y-intercept
When you know this, you would figure out that 9 is in the same place as m, and -2 is in the same place as b.
The y-intercept would not be a positive 2 because when there's a minus sign next to the number in the y-intercept spot, then you would have to bring that over to the number. We can also say the minus sign belongs to the 2, making it a -2.
With the information we know now, we can say that the slope of the equation is 9, and the y-intercept would be -2.
Therefore, giving your answer as "The slope is 9, and the y-intercept is –2"
Answer:
23y-8
Step-by-step explanation:
First add together all of the terms that are next to a variable:
2y+10y+5y+6y=23y
Then add together all of the integers that are alone:
-9+10+(-7)+(-2)= -8
Add the two terms together and you get:
23y-8
All rectangles are quadrilaterals because a quadrilateral has 4 sides and all rectangles have 4 sides so that one is correct
90 degrees for the rectangle because 360 divided by 4
Is 90 for one of them and 120 degrees for the triangle 3 divided by 360
