Answer:
The correct option is;
A)
Step-by-step explanation:
By the representation of numbers in a figurative for, we have;
1) Th rational numbers that can be expressed in the form a/b, where a and b are real numbers
2) The integers are the direct subset of the set of rational numbers and are displayed in he next larger ellipse in the figure
3) The whole numbers are the direct subset of the set of integers.
The solutions are the points where the graph intersects the x axis!
Answer:
x=1
Step-by-step explanation:
55+70=125
sum of angles in a triangle is 180 so
180-125=55
54x+1=55
x=1
Answer:
x + y = 5
<u>3x - 4y = 8</u><u> </u><u> </u><u> </u>
3x + 3y = 15
<u>3x - 4y = 8 </u>-
7y = 7
y = 1
x + y = 5
x + 1 = 5
x = 4
x = 4
y = 1
Hope it helps!
Answer:
cos x (2 sin x − 1)
Step-by-step explanation:
sin(2x) − cos x
Use double angle formula.
2 sin x cos x − cos x
Factor.
cos x (2 sin x − 1)
