Find the intersection point for the following linear functions. f(x) = 2x + 3 g(x) = -4x − 27
Ratling [72]

Answer:

(- 5, - 7 )

Step-by-step explanation:

Equate f(x) and g(x), that is

2x + 3 = - 4x - 27 ( add 4x to both sides )

6x + 3 = - 27 ( subtract 3 from both sides )

6x = - 30 ( divide both sides by 6 )

x = - 5

Substitute x = - 5 into either of the 2 functions for y- coordinate

Substituting into f(x)

f(- 5) = 2(- 5) + 3 = - 10 + 3 = - 7

Thus point of intersection = (- 5, - 7 )

For each equation below , determine the value of y if x = 2 .
Fynjy0 [20]
You simply plug in the value of x in each equation to find y.

1)
y = 7 - 3(2)
y = 7 - 6
y = 1

2)
y = 18/2
y = 9

hope this helped, blessings!

PY=2, HP=3, find HY<br><br> Geometry
klemol [59]

Answer:

HY=\sqrt{5}\ units

Step-by-step explanation:

we know that

The triangle HPY is a right triangle (because the angle ∠HYP is a right angle)

Applying the Pythagorean Theorem

HP^2=HY^2+PY^2

substitute the given values

3^2=HY^2+2^2

Solve for HY

9=HY^2+4

HY^2=9-4

HY^2=5

HY=\sqrt{5}\ units
