What is the solution to the system of equations?

Mathematics
1 answer:

5 0

Answer:

(3,2)

Step-by-step explanation:

Here's your given:

y = 4x - 10

y = 2

Because they both equal y, that means they equal each other:

2 = 4x - 10

Add 10 on both sides:

12 = 4x

Then, divide 4 on both sides:

3 = x

This represents the x coordinate.

Normally you would put this value into one of the equations to figure out y, but they already gave us that in the beginning:

y = 2

This represents the y coordinate.

Put the two values together to get: (3,2)

According to a survey of 100 people regarding their movie attendance in the last year, 40 had seen a science fiction movie, 55 h
AnnyKZ [126]

Answer:

Check attached picture ; 75 ; 40 ; 25%

Step-by-step explanation:

s = science fiction movie

H = horror movie

A = adventure movie

From the information given :

n(SnHnA) = 5

n(SnH) only = 15 - 5 = 10

n(SnA) only = 25 - 5 = 20

n(HnA) only = 5 - 5 = 0

n(S) only = 40 - (10+5+20) = 5

n(H) only = 20 - (10+5+0) = 5

n(A) only = 55 - (5 + 20 + 0) = 30

b.) Number of people who saw atleast one movie :

Sum of all numbers in the circles :

(5 + 20 + 5 + 10 + 5 + 30 + 0) = 75

c. How many people saw only one type of movie?

n(S) only + n(H) only + n(A) only

(5 + 5 + 30) = 40

d. What percentage of the people saw none of the three movie types?

Number of people who saw none of the movies:

100 - (Number of people who saw atleast one)

100 - 75 = 25

Hence, percentage who saw none :

(25/ 100) * 100%

(1/4) * 100%

= 25%

hram777 [196]

Answer:

m= 4.5 miles

Step-by-step explanation:

Let the number of miles Evelyn can run be m and can be modeled by the equation below

m= kx

Where x Is the Minutes

When m= 3

x= 40

3= k40

k= 3/40

If x= 60

m=3/40(60)

m = (60*3)/40

m= 180/40

m= 4.5 miles
