You mean -2x+5y=20 if it was that's how you do it
so if you're finding the x intercept the y will turn to 0 why because you're only looking for x their's no need for y
so it will be -2x+0=20
-2x=20 if it's multiplication then you change it to division
-2x/-2=20/-2
x=-10
Answer:
-7x≥-21
Solution:
-7x ≥ -21
÷-7 ÷-7
flip the sign when we divide by a negative number
x ≤ 3
≥ and ≤ mean closed dot

Answer:
1/4 or 0.25
Step-by-step explanation:
Find the common denominator to fill in the first 2 blanks.
1/2 = <u>2</u>/4
1/4 = <u>1</u>/4
2/4 - 1/4 = <u>1/4</u> or <u>0.25</u>
Circumference (C) = 2 π·r ; where r is the radius = diameter(d)/2
C = 2 π·(14/2)
=2 π·(7)
= 14π
