Answer:
x=3
Step-by-step explanation:
-4(4x-4)+2x-4+4=-30+4
-4(4x-4)+2x=-26
-14x+16=-26
-14x+16-16=-26-16
-14x=-42
-14x/-14=-42/-14
x=3
For this question you need to use what's called point-slope form. It's named this way because you can use it if you have both the slope and a point at which the line passes through. That said, the equation is as follows:
y - y1 = m(x - x1)
Both y1 and x1 represent the y and x coordinates you are given in the question. Also, m represents the slope of the line that you are given. Knowing this, our equation now looks like this:
y - 4 = -0.5(x - (-5))
And now simplify:
y - 4 = -0.5(x + 5)
y - 4 = -0.5x - 2.5
y = -0.5x + 1.5
Answer:
The equation which expresses the ratio of the circumference to the diameter of a circle is
⇒ D
Step-by-step explanation:
π is the ratio between the circumference of the circle and the length of its diameter
, where
- C is the circumference of the circle
- d is the diameter of the circle
∵ The circumference of the circle is C
∵ The radius of the circle is 15 units
∴ r = 15 units
- Find the diameter of the circle
∵ The diameter of the circle d = 2 r
∴ d = 2(15) = 30 units
∴ The diameter of the circle is 30 units
∵
∵ d = 30 units
∴ 
The equation which expresses the ratio of the circumference to the diameter of a circle is 
Answer:
<h2>7</h2>
Step-by-step explanation:
Look at the picture.
We have the triangle 45° - 45° - 90°. The sides are in ratio 1 : 1 : √2.
Therefore we have the equation:
