Answer:
C
Step-by-step explanation:
-3 (-1+a)+7 <5
3-3a+7 <5
-3a+10 <5 (collect like terms )
-3a <-10+5
-3a <-5(divide both side by -3)
-3a/-3 <-5/-3
a>5/3
Answer:
Hello,
Step-by-step explanation:
Loi d'Ohm: U=R*I
a) U=20*0.5=10 (amp)
b) I=U/R=50/0.5=100 (amp)
25x - 6 = 24 + 5x
First we collect terms
20x = 30
Now we divide by 20
x = 30/20
x = 1.5
Answer:
15 is larger than -4
Step-by-step explanation:
Answer:
Radius r = ±√52
Coordinates of center =
Step-by-step explanation:
Points to remember
Equation of a circle passing through the point (x1, y1) and radius r is given by
(x - x1)² + (y - y1)² = r ²
<u>To find the radius and coordinates of center</u>
It is given that an equation of circle,
(x - 4)² + (y + 6)² = 52
Compare two equations,
we get r ² = 52
r = ±√52
(x - x1)² = (x - 4)² then x1 = 4
(y - y1)² = (y + 6)² then y1 = -6
Coordinates of center = (4, -6)
