Consider f(x) = 1.8x – 10 and g(x) = −4.
Pavlova-9 [17]

Answer:

Part 1) The equation that can be used is 1.8x-10=-4

Part 2) The input or x-value is x=10/3

Step-by-step explanation:

we have

f(x)=1.8x-10

g(x)=-4

To find the solution of the system of equations equate f(x) and g(x)

f(x)=g(x)

substitute

1.8x-10=-4 -----> equation that can be used  to find the input value at which    f (x ) = g (x )

Solve for x

Adds 10 both sides

1.8x=-4+10

1.8x=6

Divide by 1.8 both sides

x=6/1.8

Remember that

1.8=18/10

substitute

x=6/(18/10)

x=60/18

Simplify

x=10/3

Find the unknown side of the triangle and explain!!!
klasskru [66]

Since this is a right triangle, we can use Pythagorean theorem. Pythagorean theorem is a^2 + b^2 = c^2

a = one leg of the triangle

b = the second leg of the triangle

c = the hypotenuse of the triangle

in this problem,

a = 8 in

b = 6 in

c = ?

We need to plug our numbers into the pythagorean theorem and solve for c

8^2 + 6^2 = c^2.

Square each term on the left side.

64 + 36 = c^2

Add the terms together on the left side.

100 = c^2.

Take the square root of each side

10 = c

The missing side is 10 inches
