Answer:

\huge\boxed{\sf (f + g)(x) = -3x + 5}

Step-by-step explanation:

<h3><u>Given functions:</u></h3>
  • f(x) = x + 8
  • g(x) = -4x - 3
<h3><u>Solution:</u></h3>

Add both functions

(f + g)(x) = x + 8 + (-4x - 3)

(f + g)(x) = x + 8 - 4x - 3

(f + g)(x) = x - 4x + 8 - 3

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

Answer:

B

Step-by-step explanation:

(f + g)(x)

= f(x) + g(x)

= x + 8 - 4x - 3 ← collect like terms

= - 3x + 5

Find the missing measures
Brrunno [24]

Answer:

y=107

x=73

z=73

Step-by-step explanation:

y and 107 are vertical angles, which means that they're the same value because they're vertically across from each other.

107 and x are supplementary angles, so x=180-107 or 73.

x and z are also vertical angles, so x=z=73.

A population of bacteria is 8500 on Day 1, 9350 on Day 2, and 10285 on Day 3.
11111nata11111 [884]

Answer:

<em>The population on 30th day will be </em><em>134836</em><em>.</em>

Step-by-step explanation:

This is a case of exponential growth. The general form of exponential function is,

y=ab^x

where, a and b are constants.

The data points from the question are (1,8500),(2,9350),(3,10285)

Putting the values in the function,

for x=1, y=8500

8500=ab  ----------1

for x=2, y=9350

9350=ab^2  ------2

Dividing equation 2 by 1,

\Rightarrow \dfrac{ab^2}{ab}=\dfrac{9350}{8500}=1.1

\Rightarrow b=1.1

Putting the value of b in equation 1,

\Rightarrow a=\dfrac{8500}{1.1}=7727.27

Now the function becomes,

y=7727.27(1.1)^x

Putting x=30, we get

y=7727.27(1.1)^{30}=134836.2\approx 134836
