Write the equation of the line that passes through (-4,3) and is parallel to y = -2x - 8.
kobusy [5.1K]

Answer:

y = -2x - 5

Step-by-step explanation:

Let the equation if the line be y = mx + c

since the line is parallel to y = -2x - 8, their gradients/slope must be the same (aka m = -2)

sub (-4, 3):

3 = -2(-4) + c

c = -5

therefore, the equation of the line is y = -2x - 5

This is a question on coordinate geometry. If you wish to venture further into it/understand this topic better, you may want to follow my Instagram account (learntionary), where I post some of my own notes on certain topics and also some tips that may be useful to you :)

While your family is visiting deep creek lake you and your mother decide to go boating. The Rangers charge $6.50 per hour in add
Fynjy0 [20]

Answer:

The Linear equation is Total \ Cost = 25+6.5h

The Total Cost to rent canoe is $44.5.

Step-by-step explanation:

Given:

deposit to rent a canoe = $25.00

Hourly charge for visiting deep creek lake = $6.50 per hour

we need to rent the canoe from 12:30 to 3:30 PM.

We need to find the total cost to rent the canoe.

Now Total number of hours (h) 12:30 to 3:30 PM = 3 hours

Hence Total Cost  will be equal to deposit to rent a canoe plus Hourly charge for visiting deep creek lake multiplied by number of hours to visit.

Hence framing in equation form we get;

Total Cost to rent canoe = 25+6.5\times h

hence the Linear equation is Total \ Cost = 25+6.5h

Solving the equation we get;

Total Cost = 25+6.5\times3 =25 +19.5 = \$44.5

Hence the Total Cost to rent canoe is $44.5.

Graphing Logarithmic Function In Exercise,sketch the graph of the function.See example 1.
Elenna [48]

Answer:

The graph of given function is shown below.

Step-by-step explanation:

The parent natural logarithmic function is

f(x)=\ln x

The given function is

y=5+\ln x

It means

y=5+f(x)              .... (1)

The translation is defined as

g(x)=kf(x+a)+b                .... (2)

Where, k is stretch factor, a is horizontal shift and b is vertical shift.

If 0<k<1, then the graph compressed vertically by factor k and if k>1, then the graph stretch vertically by factor k.

If a>0, then the graph shifts a units left and if a<0, then the graph shifts a units right.

If b>0, then the graph shifts b units up and if b<0, then the graph shifts b units down.

On comparing (1) and (2) we get

b=5

It means the graph of parent function shifts 5 units up to get the graph of given function.

Table of values:

x               y

0.25     3.614

0.5       4.307

 1             5

 2         5.693  

Plot these points on a coordinate plane connect then by a free hand curve.

The graph of given function is shown below.
