Let x be the number of boys
2/4 = 14/x
2x = 56
x=28

28 boys+ 14 girls= 42 club members

There are twice as many boys as girls. If the number of girls is 14, then there are 28 boys.

To find the total, just add: 14 + 28 = 42

That means 42 people in total.

Rewrite the function by completing the square. 4x^2-4x+1=0

andrey2020 [161]

Do in completing the square method.

${4x}^{2} - 4x + 1 = 0 \\ 4x^{2}-4x=-1 \\ \frac{4x^{2}-4x}{4}=\frac{-1}{4} \\ x^{2}+\frac{-4}{4}x=\frac{-1}{4} \\ x^{2}-x=\frac{-1}{4} \\ x^{2}-x+\left(-\frac{1}{2}\right)^{2}=-\frac{1}{4}+\left(-\frac{1}{2}\right)^{2} \\ x^{2}-x+\frac{1}{4}=\frac{-1+1}{4} \\ x^{2}-x+\frac{1}{4}=0 \\ \left(x-\frac{1}{2}\right)^{2}=0 \\ \sqrt{\left(x-\frac{1}{2}\right)^{2}}=\sqrt{0}$

Now simplify.

$x-\frac{1}{2}=0 \\ x-\frac{1}{2}=0 \\ \\ \rightarrow \: x=\frac{1}{2} \\ \rightarrow \: x=\frac{1}{2}$

So, answer is..

$\boxed{x=\frac{1}{2} }$

Now rewrite the equation.

$4 x ^ { 2 } - 4 x + 1 = 0 \\ \boxed{4\times \left(\frac{1}{4}\right)-4\times \left(\frac{1}{2}\right)+1=0 }$

Verification :-

$4 x ^ { 2 } - 4 x + 1 = 0 \\ 4\times \left(\frac{1}{4}\right)-4\times \left(\frac{1}{2}\right)+1=0 \\ 1-4\times \left(\frac{1}{2}\right)+1=0 \\ 1-\frac{4}{2}+1=0 \\ 1-2+1=0 \\ -1+1=0 \\ \underline{ 0 = 0} \: \\ \dashrightarrow \text{true}$

Step-by-step explanation:

Image result for what is always true about a line that slants downward from left to right

A line that slants down from left to right has a negative slope. Horizontal and vertical lines also have a slope. A horizontal line has a change in x, but it does not have a change in y. The slope of a horizontal line is 0.

The coordinates of point A on a grid are (−3, −2). Point A is reflected across the y-axis to obtain point B. The coordinates of

Lina20 [59]

Answer:

The coordinates of point B are (3,-2)

Step-by-step explanation:

we know that

The rule of the reflection of a point across the y-axis is given by

(x,y) -----> (-x,y)

Applying this rule to the point A(-3,-2)

A(-3,-2) --------> B(3,-2)

therefore

The coordinates of point B are (3,-2)
