10 percent of 80 is 8
5 percent of 80 is 4
so 35 percent must be 3*8 + 4 = 28

What is the equation (4, 5) m=-1/4 solved in point slope form?

hammer [34]

Answer:

Step-by-step explanation:

The point-slope form of an equation of a line:

$y-y_1=m(x-x_1)$

We have m = -1/4 and the point (4, 5). Substitute:

$y-5=-\dfrac{1}{4}(x-4)$

What is the exact solution for 75(1/5)^(x/5)=3

12345 [234]

Answer:

$\large \boxed{x = 10}$

Step-by-step explanation:

$\begin{array}{rcll}75\left (\dfrac{1}{5}\right )^{\dfrac{x}{5}} & = & 3& \\\\\left (\dfrac{1}{5}\right )^{\dfrac{x}{5}} & = & \dfrac{3}{75}&\text{Divided each side by 75} \\\\\left (\dfrac{1}{5}\right )^{\dfrac{x}{5}} & = & \dfrac{1}{25}&\text{Simplified} \\\\\left (\dfrac{1}{5}\right )^{\dfrac{x}{5}} & = &25^{-1}&\text{Applied exponent rule} \\\\\left (\dfrac{1}{5}\right )^{\dfrac{x}{5}} & = &\left (5^{2} \right )^{-1}&\text{Converted 25 to base 5} \\\\\end{array}$

$\begin{array}{rcll}\left (5^{-1}\right )^{\dfrac{x}{5}} & = &\left (5^{2} \right )^{-1}&\text{Applied exponent rule} \\\\5^{-\dfrac{x}{5}} & = &5^{-2}&\text{Multiplied exponents} \\\\-\dfrac{x}{5} & = &-2 & \text{Equated exponents}\\\\x & = & \mathbf{10} & \text{Multiplied each side by -2}\\\end{array}\\\text{The exact solution is $\large \boxed{\mathbf{x = 10}}$}$

*m is the midpoint of segment in. c has coordinates (-3, -1) and m has coordinates (0,1). find the coordinates of n

Pepsi [2]

M is the mid-point : (0,1)

c is one end : (-3, -1)

n is the other end : (x, y)

The formula for the midpoint of a line segment is : ( $\frac{ x_{1} + x_{2} }{2}$ , $\frac{ y_{1} + y_{2}}{2}$ )

Mid-point m : ( $\frac{x + (-3)}{2} , \frac{y + (-1)}{2}$ )

(0, 1) : ( $\frac{(x -3)}{2} , \frac{(y -1)}{2}$ )

Thus,

$\frac{x-3}{2} = 0$

--- x = 3

$\frac{y-1}{2} = 1$

y -1 = 2

--- y = 3

The co-ordinate of n is (3,3)
