Here are the equations for 4

Mathematics
1 answer:
Kipish [7]3 years ago
6 0

Answer:

Please see attached graph.

Step-by-step explanation:

The equations for straight lines are given as:

i) y = x +4

ii) y= x-4

Yon can form a table for values of x and y that are true for an equation and use these values as coordinates ( x,y ) to plot the graphs and view the lines to select the correct labels for the equations.  

For i)

y= x+4

x       y      coordinates

-3       1          (-3,1 )

-2        2         (-2,2)

-1         3          (-1,3)

0          4         ( 0,4)

1           5          ( 1,5)

2           6         ( 2,6)

3            7         ( 3,7)

Plot the points on a graph tool and draw the line. Do the same for the second equation to view both graphs as shown in the attached graph.

A doctor estimates that a particular patient is losing bone density at a rate of 3% annually. The patient currently has a bone d
kompoz [17]

Answer:

The function f(x) is represented by:

f(x)=1500(0.97)^x

Hence, a=1500 and b=0.97

Step-by-step explanation:

The patient currently has a bone density of 1,500 kg/mg^3.

A doctor estimates that a particular patient is losing bone density at a rate of 3% annually.

This means that the bone density that is remaining is:

100-3=97%

which is also represented as: 97%=97/100=0.97

Hence, the function f(x) that represents the bone density after x years is represented by:

f(x)=a(0.97)^x

where a is the initial bone density which is given to be: 1500 kg/mg^3.

Hence, the function is:

f(x)=1500(0.97)^x

Simplify the variable expression by evaluating it's numerical part m-13+42-6
goldfiish [28.3K]

ANSWER

m + 23

EXPLANATION

The given expression is

m - 13 + 42 - 6

We regroup the numerical parts to get;

m + 42 - 6 - 13

Now let us simplify the negative numbers.

m + 42 - 19

We now subtract 19 from 42 to get;

m + 23

We can't simplify further

Hence the simplest form is:

m + 23

What is the solution set of this inequality? 3|p + 4| + 5 < 8 (–5, –3) (–3, 0) (0, –5) (3, 5)
Viefleur [7K]

Given:

The inequality is

3|p+4|+5

To find:

The solution set for the given inequality.

Solution:

We have,

3|p+4|+5

3|p+4|

3|p+4|

Divide both sides by 3.

|p+4|

It can be written as

-1

Subtracting 4 from each side, we get

-1-4

-5

The solution set of the given inequality is (-5,-3).

Therefore, the correct option is A.
