Seth has one less than twice the number of compact discs (CDs) that Jason has. Raoul has 53 more CDs than Jason. If Seth gives J

ason 25 CDs, Seth and Jason will have the same number of CDs. How many CDs did each of the three boys have to begin with?

S = 2J - 1
R = J + 53
S - 25 = J + 25...S = J + 50

2J - 1 = J + 50
2J - J = 50 + 1
J = 51 <===Jason has 51 CD's

R = J + 53
R = 51 + 53
R = 104 <===Raoul has 104 CD's

S = 2J - 51
S = 2(51) - 1
S = 102 - 1
S = 101 <===Seth has 101 CD's

Quesheip Use the number line below, where RS = 6y +2, ST=5y + 9, and RT= 13y - 1 a What is the value of y? b Find RS, ST, and RT

Simora [160]

Answer:

$y = 6$

$RS = 38$

$ST = 39$

$RT = 77$

Step-by-step explanation:

Given:

$RS = 6y +2$

$ST=5y + 9$

$RT= 13y - 1$

Solving (a): The value of y

From the given parameters, we understand that

$RT = RS + ST$

Substitute values for RS, ST and RT

$13y - 1 = 6y + 2 + 5y + 9$

Collect Like Terms

$13y - 6y - 5y = 1 + 2 + 9$

$2y = 12$

Divide both sides by 2

$y = \frac{12}{2}$

$y = 6$

Solving (b):

<em>The value of RS</em>

Substitute 6 for y in $RS = 6y +2$

$RS = 6 * 6 + 2$

$RS = 36 + 2$

$RS = 38$

<em>The value of ST</em>

Substitute 6 for y in $ST=5y + 9$

$ST = 5 * 6 + 9$

$ST = 30 + 9$

$ST = 39$

<em>The value of ST</em>

Substitute 6 for y in $RT= 13y - 1$

$RT = 13 * 6 - 1$

$RT = 78 - 1$

$RT = 77$

Suppose the population of a town is 9,800 and is growing 2% each year. a. Write an equation to model the population growth. b. P

tiny-mole [99]

Answer:

The correct option is A.

Step-by-step explanation:

The general exponential growth model is defined as

$f(x)=a(1+r)^x$

Where, a is initial value, r is growth rate and x is time.

The initial population of town is 9800 and growth rate is 2%. The population growth model is defined as

$f(x)=9800(1+\frac{2}{100})^x$

$f(x)=9800(1+0.02)^x$

$f(x)=9800(1.02)^x$

Put x=7 to find the estimated population after 7 years.

$f(x)=9800(1.02)^7$

$f(x)=11257.119543\approx 11257$

Therefore the correct option is A.

Find an equation for the nth term of the sequence.<br> -1, -4, -16, -64, ...

Slav-nsk [51]

Answer:

An =4^(n-1)

Step-by-step explanation:

hello :

the sequence is geometric because : (-64)/(-16) = (-16)/(-4)=-4/-1= 4=r

the nth term is : An =A1 × r^(n-1)

a common ratio is : r and A1 the first term

in this exercice : r =4 A1 = 1

An =A1 × r^(n-1)

An =1 × 4^(n-1)=4^(n-1)

Find the x-intercept(s) and the coordinates of the vertex for the parabola

Drupady [299]

The answer
y=−x^2−2x-24 is like the form of y=ax² +bx +c, to find the vertex we use the formula:
the x intercept according to the vertex is x=-b/2a, and the vertex V is a point such that V [-b/2a, f(-b/2a)]
the x intercept is x= -(-2) / 2(-1) =-1, and f(-1)= -1 +2 -24= -23

the vertex is V(-1, -23)
