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.
X = 4 and y = 1
answer is (4,1) is the solution . b is the answer (2nd choice)
I think you have to figure out the gradient, so you take the 2 points and put it into the equation
change in y divided by change in x aka
y2-y1/x2-x1
so for question 3:
y2=4 and y1=3
(taken from the first and second coordinates)
x2=3 and y1=7
put these values jnto the equation
4-3/3-7 = 1/-4 (can be written as negative 1/4)
for question 4 its the same thing:
y2=9 and y1=5
x2=4 and x1=2
put into equation
9-5/4-2 = 4/2
hope this helps, im also hoping your teacher already has taught this because i didnt go into detail of where the equation came from, if not ask me and ill gladly help X
answer
c.)
Step-by-step explanation:
(-2x)^4 = -2x^4
which is the same as answer c.)
When we know 2 angles and one side, we use the Law of Sines.
First we need to find that third angle.
Angle A =
180 -41 -62 = 77 degrees
The Law of Sines states that
side a / Sine (A) = side x / Sine (X)
14 / Sine (77) = side x / Sine (41)
14 * Sine (41) / Sine (77) = side x
side x = 14 * 0.65606 / 0.97437
<span>side x = 9.18484 / 0.97437

side x = 9.4264396482
