Answer:

kaylee has 4 dimes and 10 nickles.

Mutiply 4 by ten that equals 40 then multiply 10 by 5 and get 50

2. in second soution

Nickels are worth 0.05 and dimes are worth 0.10  so if nickes + dimes = 10 and  0.05 *nickles 0.10*dimes = $0.90, then there are 2 nickels and 8 dimes.

Can you guys help?<br> Need to find x, BA, DA
7nadin3 [17]

Answer:

x=2,BA=DA which is7

Step-by-step explanation:

5x-3=3x+1

both sides share an angle and B=D right angles

5x-3x=1+3

2x=4

x=4÷2

x=2

BA=5x-3

BA=5(2)-3

BA=10-3

BA=7

DA=3x+1

DA=3(2)+1

DA=6+1

DA=7

For what value of c is the relation a function (2,8),(12,3),(c,4),(-1,8),(0,3)
Fittoniya [83]
The value of c is { c | c ∈ R, c ∉ {-1,0,2,12} }.
c is a number such that it is not in the set {-1,0,2,12} else we end up with a domain value having multiple range values, contradicting with the definition of a function.

The function f(x) = x is translated using the rule (x, y) - (x - 6, y + 9) to create A(x).
anyanavicka [17]

<em>It seems the correct function you need to mention is f(x) = sqrt x</em>

<em>so, I am assuming </em>f(x) = \sqrt{x}<em> and will solve the question based on it.</em>

Answer:

Check the explanation

Step-by-step explanation:

Given the function

f(x) = \sqrt{x}

As the function is translated according to the rule

  • (x, y) → (x - 6, y + 9)

Translation of the function f(x) = \sqrt{x} 6 units to the left will bring the function

g(x) = \sqrt{x+6}

Translation of the function  g(x) = \sqrt{x+6}  9 units up will bring the function

A\left(x\right)=\sqrt{x+6}+9

Determining the range of A\left(x\right)=\sqrt{x+6}+9

  • As we know that the range is the set of dependent values for which the function is defined.

\mathrm{The\:range\:of\:an\:radical\:function\:of\:the\:form}\:c\sqrt{ax+b}+k\:\mathrm{is}\:\:f\left(x\right)\ge \:k

k=9

f\left(x\right)\ge \:9

so

\mathrm{Range\:of\:}\sqrt{x+6}+9:\quad \begin{bmatrix}\mathrm{Solution:}\:&\:f\left(x\right)\ge \:9\:\\ \:\mathrm{Interval\:Notation:}&\:[9,\:\infty \:)\end{bmatrix}

Therefore, the expression describes the range of A(x) will be:

f\left(x\right)\ge \:\:9\:or\:y\:\ge \:\:\:9
