Adrian has $6.35 in dimes and quarters. The number of dimes is three more than three times the number of quarters. How many quar

ters does he have? What expression represents the number of dimes if q represent quarters

I: 635=dimes*10+quarters*25
or shorter
635=d*10+q*25

II: d=q*3+3

Substitute II (d=3q+3) into I to replace d:
635=d*10+q*25
635=(3q+3)*10+q*25
635=30+30q+25q
605=55q
11=q

-> 11 quarters

"What expression represents the number of dimes if q represent quarters"
insert q=11 into II:
II: d=q*3+3
d=11*3+3
d=33+3
d=36

The reciprocal parent function is translated 5 units right and 3 units up. Write an equation to represent the new function.
ladessa [460]

Answer:

The new function is y=\frac{1}{x-5}+3 , where x ≠ 5

Step-by-step explanation:

The reciprocal parent function is f(x)=\frac{1}{x} , where x ≠ 0

The translation of f(x) to the right h units is f(x - h)

The translation of f(x) up k units is f(x) + k

The translation of f(x) to the right h units and up k units is f(x - h) + k

∵ The equation of the reciprocal parent function is  y=\frac{1}{x}

∵ The function is translated 5 units right

∴ h = 5

- That means 5 is subtracted from x ⇒ (x - 5)

∵ The function is  translated 3 units up

∴ k = 3

- That means y added by 3

∴ y=\frac{1}{x-5}+3

The new function is  y=\frac{1}{x-5}+3 , where x ≠ 5

Find the sum. Express your answer in simplest form. 4x+6/y^2-9 + 8x-7/y^2-9
Amanda [17]
It looks like you already have a common denominator (y^2-9). So, you can just add the two numerators and put that over the common denominator. Hope this helps!

Solve for (0,2π]<br> 2cos ß * sin ß = cos ß
Temka [501]

Given :

An equation, 2cos ß sin ß = cos ß .

To Find :

The value for above equation in (0, 2π ] .

Solution :

Now, 2cos ß sin ß = cos ß

2 sin ß = 1

sin ß = 1/2

We know, sin ß = sin (π/6)  or sin ß = sin (5π/6) in  ( 0, 2π ] .

Therefore,

\beta = \dfrac{\pi}{6}\ or\ \beta = \dfrac{5\pi}{6}

Hence, this is the required solution.

Graph the line that represents a proportional relationship between yyy and xxx where the unit rate of change of yyy with respect
My name is Ann [436]

Answer:

y=\frac{4}{3}x

The graph in the attached figure

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=k or y=kx

In a proportional relationship the constant of proportionality k is equal to the slope m or unit rate of the line and the line passes through the origin

so

In this problem we have

k=\frac{4}{3}

substitute

y=\frac{4}{3}x

using a graphing tool
