Your question is somewhat ambiguous.
If you want to solve this equation for y in terms of x, first multiply all of its terms by the LCD (which is 5), to remove the fractions.
5(3/5)x + 5(1.4y) = 5(2/5)
Then 3x + 7y = 2 This is the equation of the line in "standard form."
Next, subtract 3x from both sides: 7y = -3x + 2
Dividing by 7, y = (-3/7)x + (2/7)
This is the slope-intercept form of the given equation. It has a slope of -3/7 and a y-intercept of (0, 2/7).
The point-slope form of the same equation is
y- 2/7 = (-3/7)(x - 0), or -3x/7. y - 2/7 = (-3/7)x
The meaning of circumference is to find the distance around a circle or in other words the perimeter of the circle. The circumference of a circle can be calculate by using the formula
C=2πr or
C=πd, where r refers to the radius.
In this exercise is given a circle, which radius is 1 yard and it is asked to find its circumference and use 3.14 as the value of pi. In order to do that, you should substitute the given value of the radius and pi into the formula C=2πr.
The circumference of the circle is 6.28 yards.
Answer:
x = 2 and x = 2
Step-by-step explanation:
Simplify this problem by factoring out the coefficient 2:
y=2x^2-8x+8 => 2(x^2 - 4x + 4)
Note that x^2 - 4x + 4 is a perfect square: (x - 2)^2.
y=2x^2-8x+8 = 2(x - 2)^2
Setting this last result = to 0, we get y = 2(x - 2)^2 = 0, which has a repeated solution: x = 2 and x = 2.
