Angle JKL is a straight angle. The measure was of MKL is 30. The measurement of angle JkM is x. What is the measure of angle jkm

k0ka [10]

ANSWER

$x=150\degree$

EXPLANATION

The given line JKL is a straight line. The angle on a straight line is 180 degrees.

This implies that the sum of the angles $\begin{gathered} Solve for x in the equation above:[tex]\begin{gathered} x=180-30 \\ x=150\degree \end{gathered}$

That is the value of x.

Let f(x) = 4x+3 and g(x) = -2x+5

brilliants [131]

f(x) = 4x + 3
g(x) = -2x + 5

(f · g)(5) = (4(5) + 3)(-2(5) + 5)
(f · g)(5) = (20 + 3)(-10 + 5)
(f · g)(5) = (23)(-5)
(f · g)(5) = -115

Find the intersection points of the linear and quadratic functions shown below f(x)=2x-5 g(x)= x2+2x-21

Mice21 [21]

Answer:

$(-4,-13)$ and $(4,3)$ the intersection points.

Step-by-step explanation:

Intersection point of two functions is a common point which satisfies both the functions.

Given functions are,

$f(x)=2x-5$

$g(x)=x^2+2x-21$

For a common point of these functions,

$f(x)=g(x)$

$2x-5=x^2+2x-21$

$-5=x^2-21$

$0=x^2-16$

$x^2=16$

$x=-4,4$

For $x=-4$ ,

$f(-4)=g(-4)=2(-4)-5$

$=-13$

For $x=4$ ,

$f(4)=g(4)=2(4)-5$

$=3$

Therefore, $(-4,-13)$ and $(4,3)$ the intersection points.
