B C=0.1 and D=0.1
I think you ment c not b for the third one so I wrote the answer to
Answer:
A: 9x-3y =5
Step-by-step explanation:
slope of the line = (8-(-1))/(-1)-(-4) = 3
so y = mx+ c , where m= slope
the equation 9x-3y= 5 has the slope 3 since we can make y the subject of the formula to get
y= 3x - 5/3..here m is also equal to 3
If you are doing division, you should be able to turn the equation around as a fact family, making it multiplication. All you need to do is 17x73=y.
y=1241
18730
You look at the 10,00 place and that is a 1 and look to the left that is 8 5 and above give it a shove! So it would round to 20,000
