Answer:
5.33% rate
Step-by-step explanation:
so here the principle(P) is 375 Naira
time(T) = 1/2 (half year)
Interest (I)= 10 Naira
rate (R)= ?
we have a formula
I =(PTR)/100
or, R =(I×100)/(PT) = (10×100)/(375×0.5)= 5.33%
Answer:
slope = 3
Step-by-step explanation:
5 - x1 -5 - y1
-1- x2 7 - y2
m= y2 - y1 / x2 - x1
m= 7 - (-5) / -1 -(-5)
m= 12 / 4
m= 3
Answer:
y ≤ -2x - 2
Step-by-step explanation:
Given question is incomplete: Find the complete question in the attachment.
Since the graphed line is a solid line and passes through two points (-2, 2) and (0, -2).
Equation of the line will be,
y = mx + b
Where m = slope of the line
b = y-intercept
Slope of the line 'm' =
=
= -2
Y-intercept 'b' = -2
Therefore equation of the line will be,
y = -2x - 2
Since the shaded region is on the left side of the solid line,
Equation of the inequality will be y ≤ -2x - 2
Answer:
C
Step-by-step explanation:
x² + 6x = 18
To complete the square, take the coefficient of the x term, halve it, square the result, then add to both sides.
(6/2)² = 3² = 9
x² + 6x + 9 = 18 + 9
(x + 3)² = 27
x + 3 = ±√27
x = -3 ± √27
Step-by-step explanation:
3x - 2 < -8 OR 3x - 3 > 18
3x < -8 + 2 OR 3x > 18 + 3
3x < -6 OR 3x > 21
x < -6/3 OR x > 21/3
x < -2 OR x > 7
