Answer:

The measure of C is 75 degrees

Step-by-step explanation:

Since ABC is isosceles, we know that C is equal to B. Therefore, we can add all the angles together and set equal to 180 to find the value of x.

A + B + C = 180

x + 5 + 3x + 3x = 180

7x + 5 = 180

7x = 175

x = 25

Now we can plug in the value of x into 3x to find C.

C = 3x

C = 3(25)

C = 75

Write an equation in point-slope form of the line that passes through the given point and has the given slope. (3, 2); m = 2/3
77julia77 [94]

Answer:

y - 2 = \frac{2}{3}(x-3)

Step-by-step explanation:

Point-slope form: y - y1 = m(x - x1)

Slope: \frac{2}{3}

Point: (3, 2) = (x1, y1)

To write the equation in point-slope form, we need to know the values of the slope and one point. Since we've already been given those values, all we have to do is input them into the equation:

y - y1 = m(x - x1)

y - 2 = \frac{2}{3}(x-3)

The equation in point-slope form is: y - 2 = \frac{2}{3}(x-3)

If f(x) and its inverse function, f^-1(x), are both plotted on the same coordinate plane, where is their point of intersection?
zloy xaker [14]

Answer:

Step-by-step explanation:

Their point of intersection, assuming there is one, will be somewhere on the line y = x.  This line, y = x, is the line of symmetry between a function and its inverse.  So if the two do in fact intersect, it will be at some point on that line

I do not know how to count following formula<br><br>x + 5 = 3
saw5 [17]
The x is going to be a negative number to get the 3. so start off minus 5 from plus 5 and minus five from the other side too. the positive 5 and the negative cancel out and then take it fromt here with three and the negative 5.
