R/10+4=5 two step equations with integers

Mathematics
1 answer:
Kamila [148]3 years ago
7 0

Answer:

So we have this equation:

r/10 + 4 = 5

FIrst, we can substract 4 in both sides

r/10 + 4 - 4 = 5 - 4

r/10  = 1

Now, we can multiply both sides per 10:

r/10 * 10 = 1 * 10

r = 10

And we know that r = 10, and that's the result of the equation.

Let f(x)=7x-13. Find f^-1(x).
vitfil [10]

Ok but allow my humble self to use y instead of f(x).

We have,

y=7x-13

If you wanna know what the inverse is swap the values of x and y,

x=7y-13

And now solve for y,

x+13=7y\implies\boxed{y=f^{-1}(x)=\frac{x+13}{7}}.

Hope this helps.

For this case we have by definition of trigonometric relations of rectangular triangles that, the sine of an angle is given by the opposite leg to the angle on the hypotenuse of the triangle. Then according to the figure we have:

Sin (40) = \frac {CA} {7}

We cleared CA:

AC = 7 * Sin (40)
