Order the steps to solve the equation log(x2 − 15) = log(2x) form 1 to 5. x2 − 2x − 15 = 0 Potential solutions are −3 and 5 x2 −

aleksley [76]

<h2>Order is 3,1,5,2 and 4.</h2>

Step-by-step explanation:

We have

log(x² - 15) = log(2x)

Solving the equation

x² - 15 = 2x

x² - 2x - 15 = 0

(x-5)(x+3) = 0

x -5 = 0 or x + 3 = 0

x = 5 or x = -3

The solutions are −3 and 5.

Order of solution is x² − 15 = 2x, x² - 2x - 15 = 0, (x − 5)(x + 3) = 0, x − 5 = 0 or x + 3 = 0 and potential solutions are −3 and 5.

Order is 3,1,5,2 and 4.

Answer:

10

Step-by-step explanation:

After spending $8, Kyle had $20 left to buy $2 ride tickets. He could buy ...

$20/$2 = 10 . . . tickets

__

An equation for the total Kyle spent is ...

total spent = (entry fee) + (ride cost) × (number of rides)

28 = 8 + 2n . . . . fill in the known values

20 = 2n . . . . . . . subtract 8

10 = n . . . . . . . . . divide by 2

Kyle bought 10 ride tickets.

Ulleksa [173]

Heya!

Here is your answer:

2 × $3^{2}$ +10

we know that,
$3^{2}$ = 9

so,

2×9 +10

According to BODMAS (bar, Order, division, multiplication, addition, subtraction)

we multiply 2×9 = 18

then,

18+ 10
= 28

A city block has 6 pigeons and then 1 week later there are 9 pigeons. Let P(t)be the number of pigeons where t is measured in we

Pavel [41]

Using proportions, it is found that the differential equation which describes the growth of the pigeon population is given by:

$\frac{dP}{dt} = 1.5P$

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, considering the initial population and the population one week later, the rate of growth is given by:

k = 9/6 = 1.5.

The standard differential equation for population growth is:

$\frac{dP}{dt} = kP$

Hence:

$\frac{dP}{dt} = 1.5P$

What is the x and y intercept of f (x) = -x^2 + 25

Masja [62]

Answer: the x intercept is -5 and the y intercept is 25.

Step-by-step explanation:

f(x) = -x^2 + 25

The x intercept is when y is zero and the y intercept is when x is zero.So input zero into the expression and solve for y.

-1(0)^2 + 25 = 25 so the y intercept is 25.

0=-x^2 +25

-25 -25

-25 = -x^2

x^2 = 25

x = -5 or 5
