Part A: In order to make an equation without a solution, all you need to do is this:
This makes the equation impossible, as no number equals itself plus two.
Part B: This is easier. Literally every random equation should work.
Now, use substitution:
x = 2
We are using a tool that determines the best fit line of the data points given. best fit line is projected to have the minimum standard deviation from the points.
Using the tool, the results are
<span><span>Best-fit values
</span><span>Slope-0.002667 ± 0.0006013
</span><span>Y-intercept6.475 ± 1.112
</span><span>X-intercept2428
</span><span>1/Slope<span>-375.0
Translating these results,
y = -0.00266 x + 6.475</span></span></span>
Answer:
A: 10.9
Step-by-step explanation: -2.3 is 2.3 away from zero then add the length from zero to the postive number which in this case is 8.6, therefore the equation is 2.3 + 8.6 = 10.9

Answer:
2.5
Step-by-step explanation:
8 -48 = 3 +13
*ADD 48 from each side(so -48+48=0 and 13+48=61)
8 = 3 +61
*Subtract from each side(so 3-3=0 and 8-3=5)
5 = 61
*Now u divide 5/5=1 and 61/5=2.5
