Answer:

The answer would be 6.7b + 2

Step-by-step explanation:

In order to simplify this, simply add the like terms together.

3.8b + 2.9b = 6.7b

-7 + 9 = 2

Now just put those two together

6.7b + 2

The graph shows the cost of some taxi journeys<br><br> work out a formula for c in terms of n
Vitek1552 [10]

Answer:

c=\frac{3}{5}(n)+2.5

Step-by-step explanation:

see the attached figure to better understand the problem

Let

c -----> the cost of some taxi journeys

n ----> the number of miles

we know that

The graph is a line

The equation of a line in slope intercept form is

c=m(n)+b

where

m is the slope

b is the c-intercept (value of c when the value of n is equal to zero)

Observing the graph  we have the points

(0,2.5), (5,5.5)

<em>Find the slope</em>

The formula to calculate the slope between two points is equal to

m=\frac{c2-c1}{n2-n1}

substitute the values

m=\frac{5.5-2.5}{5-0}

m=\frac{3}{5}

we have

b=2.5 -----> because the point (0,2.5) is the c-intercept

substitute in the equation of slope-intercept form

c=\frac{3}{5}(n)+2.5

Area <br> help hellllppppp
slega [8]

Answer:

Area = 14¹/16 yd² or 14.0625 yd²

Step-by-step explanation:

2. The figure given is a square having equal sides of 3¾ yd each.

Formula for area of the square = a²

Where,

a = 3¾ yd

Plug in the value into the equation:

Area = (3¾)²

Change to improper fraction

Area = (15/4)²

Area = 225/16

Area = 14¹/16 yd² or 14.0625 yd²

Answer: The graph is shifted vertically, but not horizontally
