Find the coordinates of the point
alina1380 [7]

Answer:

(x,y) = (\frac{-10}{13},3)

Step-by-step explanation:

<em>Question is not well formatted; However, the given parameters are</em>

Given

Point = 3/10

A = (-4,-6)

B = (10,7)

Required

Determine the coordinates of the point

Represent the point as ratio

Point = 3:10

The coordinates can be solved using

(x,y) = (\frac{mx_2 + nx_1}{m+n},\frac{my_2 + ny_1}{m+n})

Where

m:n = 3:10

(x_1,y_1) = (-4,-6)

(x_2,y_2) = (10,7)

Substitute these values in the above formula:

(x,y) = (\frac{mx_2 + nx_1}{m+n},\frac{my_2 + ny_1}{m+n})

(x,y) = (\frac{3 * 10 + 10 * -4}{3+10},\frac{3 * 7 + 10 * -6}{10+3})

(x,y) = (\frac{30 -40}{13},\frac{21 -60}{13})

(x,y) = (\frac{-10}{13},\frac{-39}{13})

(x,y) = (\frac{-10}{13},3)

Hence;

The coordinates of the point is (x,y) = (\frac{-10}{13},3)

The parameters of a linear function are the slope and the y-intercept
taurus [48]

Answer:

see the explanation

Step-by-step explanation:

we know that

A linear function in slope intercept form is equal to

f(x)=mx+b

where

m is the slope or unit rate

b is the y-intercept

x is the independent variable or input value

f(x) is the dependent variable or output value

In this problem we have

f(m)=5+3m

where

m is the number of miles

f(m) is the cab company's fare in dollars

we have that

In this context

<em>Slope</em>

The slope or unit rate is equal to the cost per mile for the riders trip

The slope is $3 per mile

<em>Y-intercept</em>

The y-intercept is the cost of the riders trip when the number of miles is equal to zero, also is called the initial value.

The y-intercept is $5

Simplify x^2-9 over x^2-3x
Alla [95]

Answer:

\frac{x+3}{x} or x+3/x

Step-by-step explanation:

Using D.O.T.S (difference of two squares) formula :

a^{2} -b^{2} = (a+b)(a-b)

x^{2} -9= (x+3)(x-3)

Factorise the second bit:

x^{2} -3x = x(x-3)

Now write out this fraction:

\frac{(x+3)(x-3)}{x(x-3)}

Now we can cancel out repeated terms (x-3):

\frac{(x+3)}{x}
This is our final answer:

\frac{x+3}{x}

Dayquan decided to run some laps around the track. If the diameter of the track is 75 feet, how far around the track did he run?
SpyIntel [72]

Answer: 235.5 feet

Step-by-step explanation:

In this case, we have to calculate the circumference of the track. The circumference will be calculated as:

= 2πr

Diameter = 75 feet.

Radius = 75/2 = 37.5 feet

Circumference = 2πr = 2 × 3.14 × 37.5 = 235.5feet
