Answer:
x = -13
Step-by-step explanation:
-5(x - 1) = -7(x + 3)
Distribute on both sides.
-5x + 5 = -7x - 21
Add 7x to both sides.
2x + 5 = -21
Subtract 5 from both sides.
2x = -26
Divide both sides by 2.
x = -13
Significant figures and decimal places are different things. If this were to be rounded to 2 DP you would be right, however Significant figures are to do with units. In this case, it would be 12cm^2

Equation that fits best in data is
.Although there are no options , kindly match this equation to options available!
<u>Step-by-step explanation:</u>
We are given a graph with y & x-axis , with 4 points given and best fit for data can be found out by joining points . On joining points , we see that best fit is a line . General equation of a line is :
,
where m = slope of line & c = intercept.
Let's calculate slope m :
Consider any two given points , let's have ( 4,0) & (3,30) :
Slope = m
⇒ m = 
⇒ m = 
⇒ m = 
So , equation now becomes :
⇒ 
at x = 0 we have y = 4



Therefore, equation that fits best in data is
.Although there are no options , kindly match this equation to options available!
