determine an equation of a line in standard form that is perpendicular lo the line 2y = -x + 3 and passes through the point (4, 5).

Answers

first, i put the equation in y=mx+b by dividing 2, since its 2y. since it’s perpendicular we’re talking about you switch the sides (opposite reciprocals). the rest should be self explanatory.

There was a 90% markup. After the markup, a 6.5%
sales tax is added.
What is the total after markup and tax?

Answers

Answer:

$109.27

Step-by-step explanation:

100 + 90 = 190

54/100 X 190 = 102.60

100 + 6.5 = 106.5

102.60/100 X 106.5 = 109.269

monetary unit round to 2dp

1. Sarah and Maya both need notebooks and pencils. The equation that represents Sarah's
purchases is y = 13- 3x. The equation that represents Maya's purchases is y = 7 -x. If y
represents the price of notebooks, and x represents the price of pencils, what are the prices of
the notebooks and pencils?
a) pencils: $4 notebook: $3 go to card 4
b) pencils: $6 notebook: $1 go to card 3
c) pencils: $3 notebook: $4 go to card 5
d) pencils: $1 notebook: $6 go to card 7
e) pencils: $4 notebook: $4 go to card 2

Answers

Step-by-step explanation:

We have y = 13 - 3x and y = 7 - x.

=> 13 - 3x = 7 - x

=> 2x = 6, x = 3.

Then y = 7 - (3), y = 4.

Hence the price of a pencil is $3 and the price of a notebook is $4. (C)

answer is c) pencils: $3 notebook: $4 go to card 5

Step-by-step explanation:

all of the angles added will add up to equal 180 so we setup the equation

180=11x-5+6x+5+x and solve

step 1 combine like terms

180=18x

step 2

divide each side by 18

x=10

then we just plug in 10 to 11x-5

11x10=110-5=105

Determine which function(s) are exponential. Select all that apply.

Answers

Answer:

option B and option C represent an exponential function.

Step-by-step explanation:

We know that following are some of the properties of different functions.

Linear Function:

The constant change in x and y

Quadratic Function:

The constant change in x

The constant 2nd differences in y

Exponential Function:

The constant change in x

The constant ratio in y

Determining the nature of the exponential function

Option A)

x 0 1 2 3 4

y 0 1 4 9 16

Here:

There is a constant change in x:

1 - 0 = 1; 2 - 1 = 1; 3 - 2 = 1; 4 - 3 = 1

BUT, there is NO CONSTANT ratio, as

1/0 = ∞, 4/1 = 4, 9/4 ; 16/9

Thus,

Table A DOES NOT represents an exponential function.

Option B)

x 0 1 2 3 4

y 1/3 1 3 9 27

Here:

There is a constant change in x:

1 - 0 = 1; 2 - 1 = 1; 3 - 2 = 1; 4 - 3 = 1

There is also a constant ratio, as

1/[1/3] = 3, 3/1 = 3, 9/3 = 3; 27/9 = 3

As there is constant change in x as well a constant ratio.

Thus,

Table B REPRESENTS an exponential function.

Option C)

x 0 1 2 3 4

y 5 5/2 5/4 5/8 5/16

Here:

There is a constant change in x:

1 - 0 = 1; 2 - 1 = 1; 3 - 2 = 1; 4 - 3 = 1

There is also a constant ratio, as

[5/2]/5= 1/2,

[5/4]/[5/2] = 1/2

[5/8]/[5/4] = 1/2

[5/16]/[5/8] = 1/2

As there is constant change in x as well a constant ratio.

Thus,

Table C REPRESENTS an exponential function.

Option D)

x 0 1 2 3 4

y 4.5 4 3.5 3 2.5

Here:

There is a constant change in x:

1 - 0 = 1; 2 - 1 = 1; 3 - 2 = 1; 4 - 3 = 1

BUT, there is NO CONSTANT ratio, as

4/4.5 = 4/[45/10] = 40/45 = 8/9

3.5/4 = [35/10]/4 = 35/40 = 7/8

3/3.5 = 3/[35/10] = 30/35 = 6/7

2.5/3 = [25/10]/3 = 25/30 = 5/6

Table D DOES NOT represent an exponential function.

Conclusion:

Therefore, option B and option C represent an exponential function.

The functions that are exponential would be:

B). [tex]x[/tex] 0 1 2 3 4

[tex]y[/tex] 1/3 1 3 9 27

C). [tex]x[/tex] 0 1 2 3 4

[tex]y[/tex] 5 5/2 5/4 5/8 5/16

What are Exponential Functions?

B). Given that,

[tex]x[/tex] 0 1 2 3 4

[tex]y[/tex] 1/3 1 3 9 27

As we see,

The value of [tex]x[/tex] undergoes a constant change of 1

[tex]1 - 0 = 1; \\2 - 1 = 1; \\3 - 2 = 1; \\4 - 3 = 1[/tex]

The ratio also remains constant

[tex]1/[1/3] = 3, \\3/1 = 3, \\9/3 = 3; \\27/9 = 3[/tex]

Thus, it exemplifies an exponential function.

Similarly,

C). [tex]x[/tex] 0 1 2 3 4

[tex]y[/tex] 5 5/2 5/4 5/8 5/16

As we see,

The value of [tex]x[/tex] undergoes a constant change of 1

[tex]1 - 0 = 1; \\2 - 1 = 1; \\3 - 2 = 1; \\4 - 3 = 1[/tex]

The ratio also remains constant

[tex][5/2]/5= 1/2\\\\[5/4]/[5/2] = 1/2\\\\[5/8]/[5/4] = 1/2\\\\[5/16]/[5/8] = 1/2[/tex]

Thus, it exemplifies an exponential function.

Thus, options B and C are the correct answers as the other two have a constant change but not a constant ratio.

A glacier moves about 3 inches every 9 hours. At this rate, about how far does the glacier move in 36 hours?
Help me please

Answers

Answer:

The answer is 12

Step-by-step explanation:

36/9=4

4x3=12

So first you would divide 12 in half to figure out how many inches it moves in 24 hours (or 1 day) which would be 6 inches every 24 hours. You then multiply 6 (inches per day) by 7 (# of days). You end up with 42 inches in 7 days. Hope this helps

Shaggy earned 7.50 an hour plus an additional $100 in tips waiting tables last night. He earned more than $160 in all. Write an inequality to represent this situation and help you find the number of hours (h) he worked.

Answers

Answer

x>21.2

Step-by-step explanation:

7.55x+100>160:

subtract 100 on both sides to get:

7.55x>60:

divide 7.55 on both sides:

x>21.2 is your answer

Answer:

7.50h + 100 > 160

Step-by-step explanation:

7.50 is the hourly wage

h = hours he worked

add 100 once because it's his tips for the amount of time her worked

since he worked more than 160, you'll use the greater sign

then solve for h

h = 8 hours
