Given point doesn't satisfy the inequality

Step-by-step explanation:

In order to check, if an inequality is satisfied by the point or not the point is put in the inequality

Given inequality is:

5x-2y+1>0

Putting the point (-2,-1) in the inequality

5(-2)-2(-1)+1>0\\-10+3+1>0\\-10+4>0\\-6>0

As -6 cannot be greater than zero,

So,

Given point doesn't satisfy the inequality

The sum of three consecutive intergers is 267. What is the largest integer
Alisiya [41]

Answer:

90

Step-by-step explanation:

Let the starting number be x, the two consecutive numbers after x is gonna be x+1 and x+2.

If the sum of these three numbers is 267 then:

x+(x+1)+(x+2)=267

Solve

3x+3=267

3x=267-3

3x=264

x=264/3

x=88

x+1=89

x+2=90

Your three consecutive numbers are 88, 89, and 90.

The largest one of them is 90.

a car rents for $40 per day plus 21 cents per mile. you are on a daily budget of $82. what mileage will allow you to stay within
pav-90 [236]

Answer:

200 miles will allow to stay within the budget

Step-by-step explanation:

∵ The daily budget is 82

∵ The cost per mile is 21/100 = $0.21

∵ The number of miles is x

∴ The equation of the budget is:

∴ 82 = 40 + 0.21 x

∴ 0.21 x = 82 - 40

∴ 0.21 x = 42

∴ x = 42/0.21 =200

∴ The number of miles = 200 to stay in the daily budget

Find the volume (in terms of pi) of a sphere of its surface area is 400 pi ft2
elixir [45]

\bf \textit{surface area of a sphere}\\\\ SA=4\pi r^2\qquad \qquad \implies \stackrel{SA}{400\pi }=4\pi r^2\implies \cfrac{400\pi }{4\pi }=r^2 \\\\\\ 100=r^2\implies \sqrt{100}=r\implies \boxed{10=r} \\\\\\ \textit{volume of a sphere}\\\\ V=\cfrac{4\pi r^3}{3}\qquad \qquad V=\cfrac{4\pi \boxed{10^3}}{3}\implies V=\cfrac{4000\pi }{3}
