Answer:
(4,5).
Step-by-step explanation:
The solution to a system of equations that is graphed is when the two lines intersect. They intersect at (4,5), so the solution to the system is (4,5). Hope this helps!
Answer:
y= -3x -2
Step-by-step explanation:
(0 , -2) and a slope of -3
The -2 is the y-intercept, put the initial point there
Use that point and put the -3 slope
Answer:
See below
Step-by-step explanation:
1-0+0-2+1=0, so since 0/11=0, it's divisible by 11
The rule for divisibility by 11 is that you subtract then add then subtract then add and so on, and if you get a number divisible by 11 or equal to 0, then it's divisible by 11.
Hope that made sense.

Answer:
43,000: 4.3×10^4
0.0072: 7.2×10^-3
0.0000901: 9.01×10^-5
Step-by-step explanation:
scientific notation: a×10^b, where should be 0<a<10
Step 1. Count the zeros
Step 2. Look at the number left, and determine whether or not it fits in the range of [a]. If not, we divide or multiply 10 to get it fit
------------------------
43,000: 4.3×10^4 (since 43 does not fit, we divide by 10 to get it fit)
0.0072: 7.2×10^-3 (since 0.72 does not fit, we multiply 10 to get it fit)
0.0000901: 9.01×10^-5 (since 0.901 does not fit, we multiply 10 to get it fit)
Hope this helps!! :)
