X = - y - 2 <br> 0.5x + y = 1

ivolga24 [154]

Answer:

Step-by-step explanation:

substitute x = - y - 2 in 0.5x + y = 1

0.5(- y - 2) + y = 1

-0.5y-1+y=1

0.5y=2

y=4

x=- y - 2

x=-4-2

x=-6

The question is in the picture

spayn [35]

Answer:

x = 10

Step-by-step explanation:

Notice that in order to solve for the final solution of x, we must look at the second step.

We use the multiplicative property of equality and multiply both sides by 5. When we do so, the left side results in simply: $\frac{1}{5} x*5=\frac{5}{5} x=x$ . Meanwhile, the right side results in: $\frac{6}{3} *5=\frac{30}{3} =10$

Thus, we have x = 10.

Hope this helps!

7x+5y=1 what is the slope of a line parallel to this line

CaHeK987 [17]

Answer:

$\textbf{The slope of the parallel line is given by $ \frac{-7}{5}$}\\$

Step-by-step explanation:

$\textup{The slope of any two parallel lines are equal and they only differ in their $y- intercepts$. }\\\textup{Given $7x + 5y = 1$}\\\textup{This can be written as: $y = \frac{-7}{5}x + \frac{1}{5}$}\\\textup{This is now comparable to $y = mx + c$, where $m$ is the slope of that line.}\\\textup{Therefore, the slope of the given line and any parallel to it is $\frac{-7}{5}$.}$
