A- Perpendicular lines have negative reciprocal slopes. Therefore a perpendicular line to 2x-8 will have a slope of -1/2. Once solved in slope intercept form, choice A shows a line of slope -2/4, equivalent to -1/2

Answer:

Choice A is correct answer.

Step-by-step explanation:

We have to find a equation of line which is perpendicular to y=2x-8.

The slope of perpendicular lines are negative reciprocals of each other.

y=mx+c is standard form of equation of line where m is slope and c is y-intercept.

given equation is :

y=2x-8

Compare above equation with standard form of equation of line,we get

m=2

The slope of perpendicular lines are negative reciprocals of each other.

Hence, m=-1/2

4y=-2x+2

dividing by 4 to both sides of above equation ,we get

Choice A is:

4y/4=-2x+2/4

y=-2/4x+2/4

y=-1/2x+1/2

hence,choice A has slope equal to -1/2.

4y=-2x+2 is equatio of line perpendicular to y=2x-8.

So,choice A is the answer.

The interior angles formed by the sides of a quadrilateral have measures that sum to 360°.

igor_vitrenko [27]

Answer: x= 34

Step-by-step explanation:

Given: The measurement of the angles of the quadrilateral are as

First angle=88°

Second angle=108°

Third angle= 2x°

Forth angle =(3x-6)°

Now, The interior angles formed by the sides of a quadrilateral have measures that sum to 360°.

Therefore,

$88+108+2x+(3x-6)=360\\\Rightarrow196+5x-6=360\\\Rightarrow\ 5x=360-190\\\Rightarrow\ x=\frac{170}{5}\\\Rightarrow\ x=34$

Shalnov [3]

Answer:

$1.475 is the average amount of snack sales per ticket sold.

Step-by-step explanation:

We are given the following in the question:

Number of popcorn bags sold = 3

Cost of a popcorn bag = $2.25

Total cost of popcorn bag = $2.25\times 3$ = $6.75

Number of soda sold = 4

Cost of a soda = $1.50

Total cost of soda = $1.50\times 4$ = $6.00

Number of candy bars sold = 2

Cost of a candy bar = $1.00

Total cost of candy bars = $1.00\times 2$ = $2.00

Total sales =

Total cost of popcorn + Total cost of soda + Total cost of candy bar

$= 6.75 + 6 + 2\\=\$14.75$

$\text{Average} = \displaystyle\frac{\text{Sum of all observations}}{\text{Total number of observation}}$

Average amount of snack sales per ticket sold =

$\dfrac{\text{Total sales}}{\text{Number of tickets}} = \dfrac{14.75}{10} = 1.475$

Thus, $1.475 is the average amount of snack sales per ticket sold.
