Solve the system of equations<br> .625x - y = -9.625<br> -65x - y = -5

Ivan

Here, 0.625x - y = -9.625
y = 0.625x + 9.625

Substitute the value of y in 2nd equation,
-65x - (0.625x + 9.625) = -5
-65x - 0.625x -9.625 = -5
-65.625x = 9.625 - 5
x = -4.625/65.625
x = -0.070

Now, substitute it in first equation,
-65(-0.070) - y = -5
4.58 + 5 = y
y = 9.58

In short, Your Answer would be: (-0.070, 9.58)

Hope this helps!

Rápido y fácil, trigonometría. Urgente porfavor

enot [183]

Answer:

The angle $\theta$ measures approximately $28.81^o$

Step-by-step explanation:

Since this problem involves the finding of an angle in a right angle triangle for which we know the opposite side and the adjacent side, the trigonometric function that relates them is the tangent:

$tan(\theta)=\frac{opposite}{adjacent}$

Then, for our case we get a starting equation that reads:

$tan(\theta)=\frac{opposite}{adjacent} \\tan(\theta)=\frac{7.7}{14}$

and for which we need to solve for $\theta$ . Then we use the arctangent function to get the final answer:

$tan(\theta)=\frac{7.7}{14} \\\theta=arctan(\frac{7.7}{14})\\\theta= 28.81^o$
