Given the slope m and a point (a,b) of a line, its equation is given by

$y-b=m(x-a)$

In your case, a = -4, b = 7 and m=1/2, so we have

$y-7=\dfrac{1}{2}(x+4) \iff y=\dfrac{x}{2}+2+7\iff y=\dfrac{x}{2}+9$

I have to find the angle measurements of a interior triangle a is 4x b is 7x-2 and c is 5x-10

RSB [31]

Answer:

$m\angle a=48^o\\m\angle b=82^o\\m\angle c=50^o$

Step-by-step explanation:

we know that

The sum of the interior angles in any triangle must be equal to 180 degrees

$m\angle a+m\angle b+m\angle c=180^o$

substitute the given values

$4x^o+(7x-2)^o+(5x-10)^o=180^o$

solve for x

$(16x-12)^o=180^o$

$16x=180+12\\16x=192\\x=12$

Find the angle measurements

$m\angle a=4(12)=48^o$

$m\angle b=7(12)-2=82^o$

$m\angle c=5(12)-10)=50^o$

What is the inverse of the function f(x) = 2x – 10?

Nadusha1986 [10]

Answer:

f⁻¹(x) = (1/2)x +5

Step-by-step explanation:

In y = f(x), swap the variables, then solve for y. The expression you get is f⁻¹(x).

... y = 2x -10

... x = 2y -10 . . . . . . swapped variables

... x +10 = 2y . . . . . add 10

... (1/2)x + 5 = y . . . . divide by 2

... f⁻¹(x) = (1/2)x + 5 . . . . . . rewrite using function notation
