What we are given:

*equation

* intercepts (4,7)

All we have to do is plug in what we know:

Y= 3x + 6

x=4 and y= 7

NEW EQUATION:

7= 3(4) + 6

7= 12+6

7= 18

then divide 18 by 7

18/7= 2.5

The equation that models this trip is T= 36x + 60 where T represents the total cost for the group to take the trip and X equals
Archy [21]

We are given

The equation that models this trip is T= 36x + 60

T represents the total cost for the group to take the trip and

X equals the number of people going

we know that

Domain is all possible values of x for which any function is defined

Since, number of people can neither be negative nor in decimals

so, x can not be negative or in decimals

now, we will check each options

option-A:

x=40

This is positive and whole number

so, this can be domain

so, this is TRUE

option-B:

x=60

This is positive and whole number

so, this can be domain

so, this is TRUE

option-C:

0< x< 40

It also includes decimals numbers

and we know that

x can not be in  decimals

so, this is FALSE

option-D:

0< x< 39

It also includes decimals numbers

and we know that

x can not be in  decimals

so, this is FALSE

A rectangle school banner has a length of 44 inches, a perimeter of 156 inches , and an area of 1496 square inches. The cheerlea
kakasveta [241]
Since you have the length and the area, you can assume the width

1496/44 = Width              Because  Area = L * W

Width = 34

So this is a ratio problem

44/11 = ratio

So, the ratio is 4:1
So since we have the width, we can divide the width of the school banner by 4 because of the scale

34/4 = 8.5 = width of the sign

The area of the sign is 8.5*11 = 93.5

and the perimeter is just that,

8.5 * 2 + 11*2 = 39

Perimeter = 39 inches

Area = 93.5 inches

of 360 consumers polled some purchase ice cream some purchase frozen yogurt and some purchase both if 260 people polled purchase
uysha [10]

Answer: There are 350 consumers who purchase frozen yogurt.

Step-by-step explanation:

Since we have given that

Number of consumers polled =360

Number of consumers who purchased ice- cream = 260

Number of consumers who purchased both ice- cream and frozen yogurt = 250

We need to find the number of consumers who purchased frozen yogurt,

Let A denotes who purchased ice-cream

and B denotes who purchased frozen yogurt.

As we know the formula

n(A\cup B)=n(A)+n(B)-n(A\cap B)\\\\360=260+n(B)-250\\\\360=10+n(B)\\\\360-10=n(B)\\\\350=n(B)

Hence, there are 350 consumers who purchase frozen yogurt.
