Will give BRAINLIEST

Mathematics

neonofarm [45]3 years ago

Step-by-step explanation:

f(x) = 2x + 1. Let y = f(x).

Then y = 2x + 1, 2x = y - 1, x = (y - 1)/2.

If h(x) is the inverse of f(x), then h(x) = (x - 1)/2 = 0.5x - 0.5.

Answer:

The sum of all the sides to this quadrilateral will equal a total of 20 inches, so you set up the equation:

2 + 2x + 7 + x + 2 = 20

Solve for x by combining like terms;

(2 + 7 + 2) + (2x + x) = 20

Which simplifies to;

11 + 3x = 20

Get rid of constants;

-11          -11

3x = 9

Isolate x by getting rid of it's coefficient;

/3  /3

<u>x = 3</u>

Now, to find the length of PQ, we plug in the value of x(3) into the equation that contains the line PQ.

x + 2

<u>3</u> + 2

= <u>5 inches.</u>

Now, to find the length of RS, we plug in the value of x(3) into the equation that contains the line RS.

2x

2(3)

= <u>6 inches.</u>

(5 × 20) + (3 × 20) What is another expression to calculate the total amount spent? A) (5 + 3) × 20 B) 5 × (20 + 3) C) 5 × 20 ×
il63 [147K]
The answer is A
your expression said 5×20=100 +3×20=60 So 100+60=160
now the option A is5+3=8 then 8×20=160 there the same product

A(n) ______ specifies the phenomena of interest; indicates which variables are independent, alternative, antecedent, intervening
Nana76 [90]

Answer:

An arrow diagram

Step-by-step explanation:

Helps keep track of intricate relationships between variables. Specifies the phenomena of interest: independent, alternative, antecedent and intervening.

-Time on the bottom with an arrow

-Antecedent -> Independent -> intervening-> dependent

An arrow diagram is defined as a process diagramming tool used to determine optimal sequence of events, and their inter-connectivity. It  is a network diagramming technique in which activities are represented by arrow, used for scheduling and to determine the critical path through nodes. The arrow diagramming method shows the required order of tasks in a project or process, the best schedule for the entire project, and potential scheduling and resource problems and their solutions. The arrow diagram lets you calculate the "critical path" of the project the flow of critical steps where delays can affect the timing of the entire project and where addition of resources can speed up the project.

One headed arrow connecting two variables= "X directly causes Y"

Explain the steps you would take to complete this conversion problem
OLEGan [10]

Answer:

20909.09 grams

Step-by-step explanation:

\frac{46 \: lb}{1}  \times  \frac{1 \: kg}{2.2 \: lb}   \times  \frac{1000 \: g}{1 \: kg}  = \\ \frac{46 \: lb}{2.2 \: lb}  \times  \frac{1 \: kg}{1} \:   \times  \frac{1000 \: g}{1 \: kg}  = \\\frac{230 \: }{11 \:}  \times \frac{1 \: kg}{1 \: kg \:}\times \frac{1000 \: g}{1 \:}  = \\\frac{230 \: }{11 \:}  \times \frac{1}{1}\times \frac{1000 \: g}{1 \:}  = \\\ \frac{230}{11}g  \times 1g  \times \: 1000g

= 230 grams / 11 grams × 1000 grams = 20.90909... × 1000 = 20909.09 grams
