Slope =(9-7)/(4-3) = 2
equation
y - 7 = 2(x - 3)
y - 7 = 2x - 6
y = 2x + 1 .....this is slope intercept form
2x - y = = -1 .....this is standard form

Brian budgeted $1,000.00 for a new computer. Will give brainly and extra points

yanalaym [24]

Answer:

<em>Brian can purchase the laptop, but not the desktop computer</em>

Step-by-step explanation:

<u>Percentages</u>

We'll evaluate two options for Brian's purchase of a new computer. The first option is to purchase a laptop with a price of $1,100. The laptops have a 15% discount. Let's compute the price of the laptop after the discount is applied:

Original price: 1,100

Discount: 15% = 15*1,100/100=165

Final price: $935

With a budget of $1,000, Brian can purchase the laptop.

Now we'll analyze the option of purchasing the desktop computer valued at $1,365 with a discount of 25%:

Original price: 1,365

Discount: 25% = 25*1,365/100=341.25

Final price: $1023.75

With a budget of $1,000, Brian cannot purchase the desktop computer.

Answer: Brian can purchase the laptop, but not the desktop computer

2) The number of streetlights in a town is growing linearly. Four months ago (n = 0) there were 130 lights. Now (n = 4) there ar

IRINA_888 [86]

Answer:

Step-by-step explanation:

Since the number of streetlights in a town is growing linearly, the street lights are increasing in arithmetic progression.

The formula for determining the nth term of an arithmetic sequence is expressed as

Tn = a + (n - 1)d

Where

a represents the first term of the sequence.

d represents the common difference.

n represents the number of terms in the sequence.

For n = 0, T0 = 130, therefore,

130 = a + (0 - 1)d

130 = a - d - - - - - - - - - -1

For n = 4, T4 = 154, therefore,

154 = a + (4 - 1)

154 = a + 3d - - - - - - - - - -2

Subtracting equation 2 from equation 1, it becomes

- 24 = - 4d

d = - 24/- 4 = 6

Substituting d = 6 into equation 1, it becomes

130 = a - 6

a = 130 + 6 = 136

a) The explicit formula for the number of lights in n months is

Tn = 136 + 6(n - 1)

b) The number of months that it will take to reach 200 lights is

200 = 136 + 6(n - 1)

200 - 136 = 6(n - 1)

64 = 6(n - 1)

6n - 6 = 64

6n = 64 + 6 = 70

n = 70/6 = 11.66

Approximately 12 months

Which exponential equation is equivalent to the logarithmic equation below?log 784 = a

Alexeev081 [22]

The general form of logarithmic function is $log_{b}$ y = x
We can transform it to exponential function by following the general form of exponential function y = $b^{x}$

we have:

b = 10 ⇒ if the base of logarithm is not given, its default value is 10
x = a
y = 784

our exponential form in this is

784 = $10^{a}$
