No they arent proportional
The answer is 25% because 20/50=0.25x100=25%
38 + 4 = 42 (1 year); 42 + 4 = 46 (2 years); 46 + 4 = 50 (3 years); 50 + 4 = 54 (4 years); 54 + 4 = 58 (5 years)
45.5 + 2.5 = 48 (1 year); 48 + 2.5 = 50.5 (2 years); 50.5 + 2.5 = 53 (3 years); 53 + 2.5 = 55.5 (4 years); 55.5 + 2.5 = 58 (5 years)
It will take 5 years before the trees are the same height, 58 inches.
Answer:
M is the slope of the equation and basically the constant rate of change. So when there are two given points, the slope of the line between them will equal m.
B is the y-intercept. The "starting point" on the y-axis.
Y is the dependant variable and the unknown that the equation solves for.
X is the independant variable, the input.
To plot an equation, plug in random x values which solves for y. After plotting 2 or more points, you can simply connect them with a line. If it's not a straight line, some of your points are wrong.
Answer:
Step-by-step explanation:
Congruent parts of congruent triangles are congruent, so we can easily demonstrate BD ≅ DF ≅ BF.
<h3>Proof</h3>
AB ≅ BC ≅ CD≅ DE≅ EF ≅ FA . . . . definition of regular hexagon
∠A ≅ ∠C ≅ ∠E . . . . definition of regular hexagon
ΔFAB ≅ ΔBCD ≅ ΔDEF . . . . SAS congruence
FB ≅ BD ≅ DF . . . . CPCTC
ΔBDF is equilateral . . . . definition of equilateral triangle
