5 0

Answer:

D) 7.5 square units

Step-by-step explanation:

The area of a triangle is found by

A = 1/2 bh

The length of the base is (50) =5

The height is  (4-1) =3

A = 1/2(5)(3)

   = 15/2

   = 7.5

A taxi fare is $3 and then $0.40 for every kilometre. A taxi fare is $9 . How far has the taxi travelled?
Charra [1.4K]

Answer:

y = 3 + 0.40x

Step-by-step explanation:

Fixed cost of taxi fare = $3

Additional cost = $0.40

Let

y = Total cost

x = number of kilometers

The equation:

Total cost = Fixed cost of taxi fare + (Additional cost * number of kilometers)

y = 3 + 0.40x

Multipy $275 by the 4.5%
4.5%=.045 (just move the decimal 2 places left)
275*.045= 12.375  Susan gets $12.375 a year (don't round yet)
Multiply $12.375 by 5years          12.375*5= 61.875 (now round)

1.) What is slope and how is it determined from an graph?
Daniel [21]

1) Slope tell about the steepness of the line.

To find slope we look at the rise and run between 2 points.


attached the graph of line with slope


slope = \frac{change in y values ( rise)}{change in x value (run)}

= \frac{2}{1}

So slope = 2

2) we have x and y intercepts


x intercept is the point where the line crosses x axis


x intercept at x= 3


y intercept is the point where the line crosses y axis


y intercept at y= 6

3) Linear equation is y= 3x+2

function is f(x) = 3x+2

We can graph it using slope and y intercept


In f(x)= 3x + 2 , slope =3 and y intercept = 2


slope = 3, rise = 3 and run =1


The graph of f(x)= 3x+2 is attached below.
