You’re going it plug in the inputs for every input for the letter x. So the first one, fx= -4(-2)+1= 9. The second one fx= -4(0)+1=1. The third one fx= -4(5)+1=19.
Just work through step by step
Follow each point until you reach one answer
Digits = 7
-9 = reverse
16 - 9 = 7 x
25 - 9 = 16 x
34 - 9 = 25 x
43 - 9 = 34 Y
52 - 9 = 43 x
61 - 9 = 52 x
4 + 3 = 7
43 - 9 = 34 - the digits have been reversed
43
V (cube)=9³=729 cm³
V (cone)=1/3*π*R²*H= 1/3*π*3²*9=84.8 cm³
V (metal)= 729-84.8=644.2 cm³
Answer:
See explanation
Step-by-step explanation:
One vertex is at point (2,3).
Go 1 unit to the left and 5 units up, then the second vertex will be at the point (1,8).
Go 5 units to the right and 1 unit up, then the third vertex will be at point (6,9).
Go 1 unit to the right and 5 units down, then the fourth vertex will be at point (7,4).
Go 5 units to the left and 1 unit down to get into the vertex (2,3).
Since you always move one unit in one direction and 5 units in another direction, obtained quadrilateral will be a square.
See attached diagram for details.
Given the proportion 7/5=x/3, you can cross-multiply to find the value of x.
21=5x.
Divide both sides by 5.
x=4.2.
Hope this helps!
