Answer:

B) -5x + 2y + 1 > 0

Step-by-step explanation:

Given point is (-2,-1)

to find out which inequality satisfies this point we plug in x and y value of the given point in each inequality

A) 5x - 2y + 1 > 0

x=-2 and y=-1

5(-2) - 2(-1) + 1 > 0

-10+2+1>0

-7>0 is False

B) -5x + 2y + 1 > 0

-5(-2) +2(-1) + 1 > 0

10-2+1>0

9>0 is True

C) -2x + 5y - 1 > 0

-2(-2) +5(-1) -1 > 0

4-5-1>0

-2>0 is False

D) 2x + 5y - 1 > 0

2(-2) +5(-1) - 1 > 0

-4-5-1>0

-10>0 is False

5.Solve the quadratic equation.
Dafna1 [17]

Answer:

x=5 twice

Step-by-step explanation:

x^2-10x+25=0

multiply the coefficient of x^2 and the last term

1X25=25

find two numbers you can multiply to get 25 and add to get -10

-5 + (-5)=-10 the middle term

replace -10x with -5x -5x and solve the equation

x^2-5x-5x+25=0

factorise by grouping

x(x-5)-5(x-5)=0

(x-5)(x-5)=0

Either x-5=0,x=5 or x-5=0,x=5

Therefore x=5 twice.

Team infinite dimensions canoed 15 3/4 miles in 3 hours. what was their average rate of speed in miles per hour?
Karo-lina-s [1.5K]
Miles per hour

(15 and 3/4) miles per 3 hours

remember that
(a+b)/c=(a/c)+(b/c)
and
a and c/d=a+c/d

so

(15 and 3/4)/3=(15/3)+(3/4)/3
remember that dividing by a number is like multiplying by a fraction
15/3=5
(3/4)/3=(3/4) times (1/3)=3/12=1/4

(15/3)+(3/4)/3=5+1/4=5 and 1/4

answer is 5 and 1/4 miles per hour
