Which are the solution of x2 =-5x +8

Mathematics
1 answer:
Salsk061 [2.6K]4 years ago
6 0

Answer:

x=6/5 or 1.2

Step-by-step explanation:

I could not tell if your original problem was 2=-5x+8 or if it should have been 2x=-5x+8 so I solved both

2= -5x+8 (next subtract 8 from both sides)

-6= -5x (divide both sides by -5)

-6/-5=x (the negative cancel out next)

6/5 or 1.20 is x

If your original problem should say 2x=-5x+8

2x=-5x+8 (add 5x to both sides next)

7x=8 (divide by 7 on both sides)

x=8/7

Write the following decimal number in its equivalent fraction form.
Alecsey [184]

Answer:

-0.6666.... = - \frac{2}{3}

Step-by-step explanation:

Repeating decimals can be written as either 0.6666..., or as 0.6 with a small line over the top of the 6 to indicate it repeats.  Repeating fractions are not put into fractions in the traditional way.  If we had the terminating decimal 0.4, then we know to put the 4 over 10 and reduce:

\frac{4}{10}=\frac{2}{5}

However, with repeating decimals, instead of putting the number of the decimal over a value of 10, we put it over a value of 9.  So, for the equivalent fraction form of -0.6 (repeating) we would get:

\frac{6}{9}=-\frac{2}{3}

Which of the following is equation of a line that passes through the point (2,5) and (4,3)
BartSMP [9]

Step-by-step explanation:

The correct answer is C as it has the same line of equation. We can make this clear by verifying that these two points make the same equation or not. So as we can see if we calculate the gradient using the formula y2 - y1 / x2 - x1.
