Answer:
a number that is substituted in an inequality that makes the inequality a true statement.
EXAMPLE :
x + 2 < 7 ; x= 4
1) substitute 4 into the inequality
4 + 2 < 7
2) solve ( add 4 and 2 together )
6 < 7
the number 4 is a solution to the inequality because 6 < 7 is true.
Answer:
6 bushes and 2 fences
Step-by-step explanation:
Let 2x be the no. of bushes and 2y be the no. of fences
2x+2y = 8
18(2x)+25(2y) less than/equal to 164
2y = 8 - 2x
18(2x) + 25(8-2x) 《 164
36x + 200 - 50x 《 164
14x 》 36
x 》 18/7
x = 3
y = 1
2x = 6
2y = 2
Answer:
The system of equation y=120+20x and y=30x
Step-by-step explanation:
Let the number of days be x and y be the total number minutes
Jamie has walked 120 mins. She will walk at a rate of 20 mins per day.
y=120+20x
Owen walks 30 mins a day. So
y = 30x

hello :<span>
<span>an equation of the circle Center at the
A(a,b) and ridus : r is :
(x-a)² +(y-b)² = r²
in this exercice : a =-2 and b = 2 (Center at the point A(-2;-2))
r= 10/2=5
the equation is : (x+2)² +(y+2)² =25</span></span>
Answer:
10 and 7
Step-by-step explanation:
First you can list out numbers 1-10 and find thngs that equal 3 when subtracted. Then after you do that see if when you multiply y x 3 subtracted from x if it equals -11.
10-7 =3
10 - (7x3)
10 - 21
-11
