Answer:

x=8

Step-by-step explanation:

The objective is to solve for x.

The objective is to get x = something

Remember if you do something to one side you have to do the same thing to the other side.

add three 2x +16 = 4x

subtract 2x 16 = 2x

divide by two x = 8

remember to check 16+13 =29=32-3=29

A=1/2 bh for b i need help

qwelly [4]

You said that  A = 1/2 b h

Multiply each side by 2 : 2A = b h

Divide each side by 'h' : 2A/h = b

Given the function f(x) = - 4x + 2. Find the range using the domain. D:{-1, 2} R:{ , }

Svet_ta [14]

Answer:

R { - 6, 6 }

Step-by-step explanation:

To find the range substitute the values of x from the domain into f(x)

f(- 1) = - 4(- 1) + 2 = 4 + 2 = 6

f(2) = - 4(2) + 2 = - 8 + 2 = - 6

Range { - 6, 6 }

Triangle S R Q is shown. Angle S R Q is a right angle. An altitude is drawn from point R to point T on side S Q to form a right

juin [17]

Answer:

RT = 12 units

Step-by-step explanation:

From the figure attached,

ΔSRQ is right triangle.

m∠R = 90°

An altitude has been constructed from point T to side SQ.

m∠RTQ = 90°

By applying geometric mean theorem in triangle SRQ,

$\frac{\text{RT}}{\text{ST}}=\frac{\text{TQ}}{\text{RT}}$

$\frac{x}{9}=\frac{16}{x}$

x² = 16 × 9

x² = 144

x = √144

x = 12

Therefore, length of altitude RT is 12 units.
