Answer:
4, 8, 16, 32
Step-by-step explanation:
4, 8, 16, 32 is a geometric sequence. The value multiplies by 2 every time.
If angle D is congruent to angle E, then the triangle DFE is an isosceles triangle (look at the picture).
Therefore DF ≅ EF.
DE = x + 4, EF = 4x - 8, DF = 7x - 35
The equation:
7x - 35 = 4x - 8 <em>add 35 to both sides</em>
7x = 4x + 27 <em>subtract 4x from both sides</em>
3x = 27 <em>divide both sides by 3</em>
x = 9
DE = x + 4 → DE = 9 + 4 = 13
EF = 4x - 8 → EF = 4(9) - 8 = 36 - 8 = 28
DF = 7x - 35 → DF = 7(9) - 35 = 63 - 35 = 28
<h3>Answer:</h3><h3>x = 9, DE = 13, EF = 28, DF = 28.</h3>
Multiply straight across:
-6 x -8 = 48
5 x 9 = 45
Simplify:
48/45 = 16/15
16/15, or 1 1/15 is your answer

<u>Answer</u>
yes it does.
<u>Explanation</u>
The equation of a straight line is in the form of Y = mX + c, where m is a constant (the gradient) and c is the y-intercept.
The equation above, y= 4x +3 is the equation of a straight line.
y ∝ x
Introducing the constant of proportionality now become y = 4x. When like this the a line is a straight line from the origin but when we add 3 in the equation we have. Y = 4X + 3.
The equation remains proportional. This time the line passes through the point (0,3).
