Answer:

-11

Step-by-step explanation:

assuming 4x-3 = f(x) and the other equation = g(x)

(4x-3) - (x^2 +2x)

(4(4)-3) - (4^2 +2(4)

(16-3)-(16+8)

(13)-(24)

-11

Evaluate the function<br> f(x) = - 2x^2 + 2x + 4<br> Find f(1)
AlekseyPX

Answer:

f(1) = 4

Step-by-step explanation:

f(x) = - 2x^2 + 2x + 4

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

f(1) = -2 + 2 + 4

f(1) = 4

Does anyone know how to do this? Im so confused.
Dafna11 [192]
<h3>Answer:  PC = 5</h3>

================================================

Work Shown:

AB+BC+CD = AD .... segment addition postulate

BC+BC+CD = AD ... replace AB with BC (since AB = BC)

BC+BC+BC = AD ... replace CD with BC (since BC = BC)

3*BC = AD .... combine like terms

3*BC = 12 .... replace AD with 12

BC = 12/3 .... divide both sides by 3

BC = 4

For right triangle PBC, the legs are BP = 3 and BC = 4. We can use the Pythagorean Theorem to find that the hypotenuse is PC = 5

The steps are shown below

(BP)^2+(BC)^2 = (PC)^2

3^2+4^2 = (PC)^2

9+16 = (PC)^2

25 = (PC)^2

(PC)^2 = 25

PC = sqrt(25)

PC = 5

The other parts of the diagram seem to be thrown in as a distraction.

Write the equivalent logarithmic equation to 10^a = x+b
MA_775_DIABLO [31]

Answer:

The answer to your question is   log₁₀ x + b = a        

Step-by-step explanation:

General formula

                 Logarithmic function                Exponential function

                           log ₐ b = c                                  b^{c} = a

a = antilogaritm                                               c = exponent

b = base                                                          b = base

c = logaritm                                                     a = power

In your problem

10 = base

a = exponent

x + b = power

Exponential function              log₁₀ x + b = a

Elliott is 63 inches tall, which is 9inches taller than cousin, Jackson.write and solve an addition equation to find Jackson hei
Nataly [62]

Answer:

J + 9 = 63

Jackson = 54 inches

Step-by-step explanation:

Using the variable 'J' for the height of Jackson, we know that Elliott is Jackson's height, plus an additional 9 inches.  Since Elliott is 64 inches tall in total, we can add Jackson's height plus 9 to get Elliot's height:

Jackson's height + 9 inches = Elliot's height

J + 9 = 63

Subtract '9' from both sides: J + 9 - 9 = 63 - 9 or J = 54

So, Jackson is 54 inches tall.
