SSSSS [86.1K]

Equivalent equations are equations of equal values

The system of equations from the given equation are:

y= \log_2(2x) and y=3\log_4(x)

The logarithmic equation is given as:

\log_4(x^3) = \log_2(2x)

Split the above equation as follows:

y = \log_4(x^3)

y= \log_2(2x)

Rewrite y = \log_4(x^3) as:

y=3\log_4(x)

Hence, the system of equations from the given equation are:

y= \log_2(2x) and y=3\log_4(x)

1. Evaluate -3x^3 -2y^2 when x=-5 and y =3
-Dominant- [34]

Answer:

357

Step-by-step explanation:

A) We replace x = - 5 and u = 3 into -3x^3 -2y^2

and we have -3x^3 -2y^2= -3*(-5)^3 -2*3^2= -3*(-125)- 2*9

or -3x^3 -2y^2 = 375-18= 357

The answer is 357.

B) Replace h = -2 into h^2-3h+2

we have h^2-3h+2 = (-2)^2 -3*(-2) +2 = 4 +6 + 2= 12

The answer is 12

Have a good day.

First car is x
second car is y
25x+30y=1550
x+y=55
Multiply the second equation by -25 for elimination method to cancel out x
-25x-25y=-1375
Add the two equations
5y=175
y=35
Plug this value into the second equation
x+35=55
x=20

Final answers:
First car=20 gallons
Second car=35 gallons

Provide steps please
KengaRu [80]

Answer:

5 cm

Step-by-step explanation:

The volume (V) of a cuboid is calculated as

V = lbh ( l is length, b is breadth and h is height )

Here l = 20, h = 12, V = 1200 and b is to be found, thus

20 × b × 12 = 1200, that is

240b = 1200 ( divide both sides by 240 )

b = 5

A bag contains a total of 60 marbles. A marble is to be chosen at random from the bag. If the probability that a blue marble wil
valkas [14]

Answer:

There are 21 blue marbles

Step-by-step explanation:

In this question, we are asked to calculate the number of blue marbles in a bag that contains a total of 60 marbles, given the probability of choosing a blue marble.

Mathematically, the probability of choosing a blue marble can be represented as:

P(B) = number of blue marbles/ Total number of marbles

From the question, we can identify that P(B) is 0.35, number of Marbles is unknown while the total number of marbles is 60.

We insert these values in the equation;

0.35 = number of blue marbles/60

Hence, number of blue marbles = 60 * 0.35 = 21
