-5(x - 1) = – 7(x+3)<br> whats the answer
VARVARA [1.3K]

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

Which equation represents the line of BEST fit for the data?
Sladkaya [172]

Equation that fits best in data is y = -30x + 4 .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 : y = mx + c ,

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 = \frac{y_2-y_1}{x_2-x_1}

⇒ m = \frac{0-30}{4-3}

⇒ m = -30

So , equation now becomes : y = mx + c

⇒ y = -30x + c

at x = 0 we have y = 4

y = -30x + c

4 = -30(0) + c

c = 4

Therefore, equation that fits best in data is y = -30x + 4 .Although there are no options , kindly match this equation to options available!
