Answer:
6160
Step-by-step explanation:
If you do not understand my solution, send a picture of how your teacher does it and I will guide you in the same style as your teacher.
you have numbers: 16 28 40 77. I will write each number in each line and show its multiple numbers: Now that if you multiply the numbers I write, you get the same number. For example, 2*2*2*2 = 16 (same for the rest)
16: 2 2 2 2
28: 2 2 7
40: 2 2 2 5
77: 7 11
From the above, we pick 2*2*2*2*5*7*11 = 6160
I got that by picking a number comprised of factors that appear in at least any of the numbers 16 28 40 77
Answer:
A
Step-by-step explanation:
From the diagram:
- P(-4,6)→P'(4,6);
- Q(-7,4)→Q'(7,4);
- R(-6,1)→R'(6,1);
- S(-2,1)→S'(2,1);
- T(-1,4)→T'(1,4).
The general rule of this reflection is
(x,y)→(-x,y)
and this is reflection across the y-axis. The y-axis has the equation x=0.
-1\4
Step-by-step explanation:
find the gradient of the line
Answer:
Step-by-step explanation:
y=x²-2x-1
and y=-3x+5
x²-2x-1=-3x+5
x²+x-6=0
x²+3x-2x-6=0
x(x+3)-2(x+3)=0
(x+3)(x-2)=0
x=-3,2
when x=-3
y=-3×-3+5=9+5=14
when x=2
y=-3×2+5=-6+5=-1
so solutions are (-3,14) and (2,-1)
