Is (2, -4) a solution to the inequality 2x - 3y < 15? Yes or No

Mathematics High School

Is (2, -4) a solution to the inequality 2x - 3y < 15? Yes or No

Answers

Answer 1

Answer:

No.

Step-by-step explanation:

We substitute the values x = 2 and y = -4 into the inequality.

Left side = 2(2) - 3(-4) = 4 + 12

= 16

Now the right side is 15 so we get 16 < 15 which is incorrect.

So (2, -4) is not a solution.

If one tenement on the Lower East Side of New York had 101 adults and 91 children, and there was an average of 8 persons in a tenement apartment, how many apartments did this tenement have?

Answers

Answer:

24 Apartments

Step-by-step explanation:

To get the total amount of people living in the apartment building, you add 101 and 92.

101+91=192 total people

You then divide this total by the amount of people staying in each apartment, which is 8.

192/8=24 apartments

This leaves you with 24 apartments, with 8 people living in each one.

If your driving 60miles an hour and you drive for 1hour how far do you travel?

Answers

Answer:

60 miles

Step-by-step explanation:

1 hour=60 miles

To solve this problem, we’ll utilize the “time-speed-distance” relationship which is expressed by the formula d = rt, i.e., distance d is equal to speed r multiplied by time t.

The given information in this problem gives us: the speed of r = 60 mi/hr traveled over a distance of 1 mile. We need to find how much time, t, it took to travel a distance d of 1 mile at a speed r = 60 mi/hr, that is:

d/r = t or

t = d/r

Substituting the known values for d and r into the above equation, we have:

t = 1 mi./(60 mi/hr)

t = (1/60) hr.

t = (1/60) hr. (1)

t = (1/60) hr. (60 min./1 hr.)

t = (1/60)(60/1) min.

t = 1 minute ( or 60 seconds) to travel 1 mile at a speed of 60 miles per hour.

Share 39 in the ratio 3:3:7

Answers

Answer:

9 : 9 : 21

Step-by-step explanation:

sum the parts of the ratio, 3 + 3 + 7 = 13 parts

Divide 39 by 13 to find the value of one part of the ratio

39 ÷ 13 = 3 ← value of 1 part of the ratio, then

3 parts = 3 × 3 = 9

7 parts = 7 × 3 = 21

Then 39 in ratio 3 : 3 : 7 = 9 : 9 : 21

The equation for the line of best fit shows the relationship between the number of students enrolled

The equation for the line of best fit, then predict the number of students enrolled in 2011 is [tex]y = 90.2x - 177670.2[/tex]

How to determine the equation of the line of best fit

To do this, we make use of a graphing calculator that has the following calculation summary

Sum of X = 10020Sum of Y = 15453Mean X = 2004Mean Y = 3090.6Sum of squares (SSX) = 10Sum of products (SP) = 902b = 90.2a = -177670.2

A regression equation is represented as:

[tex]y = bx + a[/tex]

So, we have:

[tex]y = 90.2x - 177670.2[/tex]

Hence, the regression equation is [tex]y = 90.2x - 177670.2[/tex]
