[tex]y = - x - 1[/tex]

[tex]y = - 5x - 13[/tex]

Multiply the lower equation by -1:

[tex]y = - x - 1[/tex]

[tex] - y = 5x + 13[/tex]

Add the systems:

[tex]0 = 4x + 12[/tex]

[tex]4x = - 12[/tex]

[tex]x = \frac{ - 12}{4} = - 3[/tex]

Substitute x=3 in any equation:

A store sells an 8-pound bag of flour for $18.80. If larry can buy a 2-pound bag of flour at the same rate, what would be the price of the 2-pound bag?

Answers

Answer:

$4.70

Step-by-step explanation:

First, you need to divide 18.80 by 8.

18.80/8 = 2.35

2.35 is the unit price for one (1) pound bag of flour,

Multiply by 2 to find the price of a two (2) pound bag.

2.35 * 2 = 4.7

$4.70 is the price of a two-pound bag.

Number of workers is inversely proportional to the amount of days required

Here :

6 workers construct 10 m long wall in 4 daysThen, for 2 workers to construct the same length, it will take 3 times the amount of time as number of men has been divided by 32 workers to construct 10 m long wall = 4 x 3 = 12 daysFor them to construct 15 m long wall, multiply the number of days by 1.5 as 10 x 1.5 = 15No. of days for 2 workers to construct 15 m long wall :12 x 1.5 = 18 days

Line symmetry is when a shape can be folded over an imaginary axis and have both sides be a mirror of the other. This axis is called the line of symmetry.

Letter C

In this case, if you draw a horizontal line across the middle of the letter "C" and fold the letter, each half would be the same. The top half of "C" mirrors the lower half.

Step-by-step explanation:

Answer:

See below ~

Step-by-step explanation:

Let Jim, Steve, and Matt have speeds of j, s, and m respectivelyFrom the problem :j = s - 3 [Jim]s = m - 4 [Steve]

Jim takes same time to walk 25 miles at it takes Matt to ride 60 milesj = 25/t₁ and m = 60/t₁Steve runs 16 miles in the same time Matt rides his bike 24 miless = 16/t₂ and m = 24/t₂

Equating Matt's Speed in both cases

60/t₁ = 24/t₂t₁/t₂ = 5/2 = 2.5t₁ = 2.5t₂

Now, taking Equation 1 :

j = s - 325/t₁ = 16/t₂ - 325/(2.5t₂) = 16/t₂ - 310/t₂ = 16/t₂ - 36/t₂ = 3t₂ = 2 st₁ = 2.5(2) = 5 secondsEq.1) m = 60/5 [Matt]

Now, taking Equation 2 :

s = m - 416/t₂ = 24/t₂ - 48/t₂ = 4t₂ = 2 secondsEq.2) m = 24/2 [Matt]

The equation that is equivalent to the considered equation of log is given by: Option E: 2^3 = x+5

What is logarithm and some of its useful properties?

When you raise a number with an exponent, there comes a result.

Lets say you get [tex]a^b = c[/tex]

Then, you can write 'b' in terms of 'a' and 'c' using logarithm as follows

[tex]b = \log_a(c)[/tex]

'a' is called base of this log function. We say that 'b' is the logarithm of 'c' to base 'a'

Some properties of logarithm are:

[tex]\log_a(b) = \log_a(c) \implies b = c\\\\\log_a(b) + \log_a(c) = \log_a(b \times c)\\\\\log_a(b) - \log_a(c) = \log_a(\frac{b}{c})\\\\\log_a(b^c) = c \times \log_a(b)\\\\\log_b(b) = 1\\\\\log_a(b) \times log_b(c) = \log_a(c)[/tex]

Log with base e = 2.71828... is written as [tex]\ln(x)[/tex] simply.

Log with base 10 is written as [tex]\log(x)[/tex] simply.


The equation given is:

[tex]\log_3(x+5) = 2[/tex]

By using the definition of log, which says [tex]a^b = c \leftrightarrow \log_a(c) = b[/tex], we get:

[tex](x+5) = 2^3[/tex] or [tex]2^3 = x+5[/tex]

Thus, the equation that is equivalent to the considered equation of log is given by: Option E: [tex]2^3 = x+5[/tex]

(we used the fact that the question is asked in a way that expresses that there is only one equivalent equation. Plus we used the fact that as option E is a sure equivalent version, so it is correct option).

Thus, the equation that is equivalent to the considered equation of log is given by: Option E: [tex]2^3 = x+5[/tex]

Suppose a normal distribution has a mean of 98 and a standard deviation of
6. What is P(x s 110)?
A. 0.975
B. 0.84
O C. 0.025
OD. 0.16

Answers

The probability (x s 110) is 0.975, the correct option is A.

What are mean and median?

The mean is the average value which can be calculated by dividing the sum of observations by the number of observations

Mean = Sum of observations/the number of observations

Median represents the middle value of the given data when arranged in a particular order.

We are given that;

Mean=98

Now,

To find the probability that x is less than or equal to 110 for a normal distribution with mean 98 and standard deviation 6, we need to use the standard normal table or a calculator.

Using the standard normal table, we first need to convert x to a z-score using the formula:

z = (x - mean) / standard deviation

Plugging in x = 110, mean = 98 and standard deviation = 6, we get:

z = (110 - 98) / 6

z = 2

This means that x = 110 is equivalent to z = 2 on the standard normal distribution.

Now we look up the value of z = 2 on the table and find that it corresponds to an area of 0.9772. This means that P(z ≤ 2) = 0.9772.

However, this is not the answer we want. We want P(x ≤ 110), which is the same as P(z ≤ 2). The table gives us the area to the left of z, but we need to subtract it from 1 to get the area to the right of z. This is because P(x ≤ 110) = P(z ≤ 2) + P(z > 2) = 1.

Therefore,

P(x ≤ 110) = P(z ≤ 2)

P(x ≤ 110) = 1 - P(z > 2)

P(x ≤ 110) = 1 - (1 - P(z ≤ 2))

P(x ≤ 110) = P(z ≤ 2)

P(x ≤ 110) ≈0.9772

Therefore, by the given mean the answer will be 0.975.
