Step-by-step explanation:
4 + 7 x 3 - 24 x 2 + 20x - 16
4 + 21 - 48 + 20x - 16
-39+20x
Answer:
Hello I'm pretty sure the answer is 20
Hope This Helps :D
Please let me know if I am incorrect pretty sure its right tho
Answer:
70
Step-by-step explanation:
So I assumed that the x was multiplication...so...15x3=45 and 33x5=165...so the perimeter is 210, so you divide that by 3 and the answer is 70!

X= -4
Step-by-step explanation:
6x + 18 = -6
6x= -24
x= -4
Answer:
1
Step-by-step explanation:
By gradient, if you mean the "slope" of the linear function, then you have to find two points of the graph and use the "rise over run strategy". Given two coordinates, (x1, y1) and (x2, y2) of a linear function in the form y=mx+b, the slope of the line is (y2-y1)/(x2-x1). This shows the amount of "rise", or the vertical change, and the amount of "run", which is the horizontal change. Rise/Run gives the steepness of the line. The slope can also be modeled by Δy/Δx, which is the change in y over the change in x
Plugging in the given points (0,5) and (-5,0):
(y2-y1)/(x2-x1)= (5-0)/(0-(-5)) = 5/5 = 1
