Answer:
45 Handshakes.
Step-by-step explanation:
10 people shake hands.
So, each person will shake hands with 9 other people.
Total number of handshakes = 90/2 = 45
Answer:
A:(-2,-3)
B:(-4.009,1.018) And (-2,-3)
C:x≈0,1.61878812
Step-by-step explanation:
I found the equations
g(x)=e^x+1
p(x)=5/2x+2
f(x)=-2x-7
plugged it in on a graph found the answer to find g(x) all you need to do is know the parent function y=e^2(exponential) and I found where the lines intersect for part A and B and or p(x)=g(x) I did e^x+1=(5/2)x+2
Answer: (-1, 2)
Step-by-step explanation:
<u>It's a counter-clockwise rotation, that means (x, y) changes to (y, -x).</u>
(-2, -1) ⇒ (-1, -(-2)) ⇒ (-1, 2)
<u>If it's a clockwise rotation, then (x, y) will change to (-y, x)</u>
(-2, -1) ⇒ (-(-1), -2) ⇒ (1, -2)
Answer: a.) -1 2/3
explanation: -2 1/6 - 1 1/4= -13/6 - 5/4= -41/12 ; 1 3/4= 7/4 ; -41/12 + 7/4= -5/3 ; -5/3= -1 2/3
Answer: x = - 16
y = - 11
Step-by-step explanation:
The given system of linear equations is expressed as
2x - 3y = 1- - - - - - - - - - - - -1
x - 2y = 6 - - - - - - - - - - - -2
We would eliminate x by multiplying equation 1 by 1 and equation 2 by 2. It becomes
2x - 3y = 1- - - - - - - - - - -3
2x - 4y = 12- - - - - - - - - - - -4
Subtracting equation 4 from equation 3, it becomes
y = - 11
Substituting y = - 11 into equation 2, it becomes
x - 2 × - 11 = 6
x + 22 = 6
Subtracting 22 from the left hand side and the right hand side of the equation, it becomes
x + 22 - 22 = 6 - 22
x = - 16
