Find the range of the function r(x) for the given domain. r(x) = 2(2*)+3 D = {-1,0,1,3}

e-lub [12.9K]

Answer: R = {4, 5, 7, 19}

Step-by-step explanation:

Domain represents the x-values.

Range represents the y-values.

Insert the values of the domain into the given equation.

$\begin {array}{c|l|c}\underline{\ x\ }&\underline{\ 2(2^x)+3 =\ }&\underline{\ r(x)\ }\\ -1&2(2^{-1})+3=&4\\0&2(2^0)+3=&5\\1&2(2^1)+3=&7\\3&2(2^3)+3=&19\\\end{array}$

Slope intercept y=mx + b, add y to both sides in your equation. Y=4x, slope intercept. Graphing should be easy, just plug in x intercepts

The digits in the tens place of a two-digit number are 3 more than the digits in the unit place. If the digit at the unit place

Tems11 [23]

Answer:

Step-by-step explanation:

We are told that the number at the unit place is 3 less than the number at the tens place.

So if the number at the units place is b, then the number at the tens place is 10(b+ 3)

So the number is thus;

10(b + 3) + b

= 10b + 30 + b = 11b + 30

Solve for x. x = ___°

irina [24]

x = 109

this is pentagon

the sum of the interior angles of a polygon is

sum = 180°( n - 2) where n is the number of sides.

sum = 180° × 3 = 540° thus

x + 121+ 108 + 102 + 100 = 540

x + 431 = 540

subtract 431 from both sides

x = 540 - 431 = 109
