​

Answer:

40.42 ÷ 4.3 = 9.4

The value of y in the linear equation 7x - 6y = 17 is y = -(17 + 7x)/6

Linear equations are equations of the first order. The linear equations are defined for lines in the coordinate system. When the equation has a homogeneous variable of degree 1 (i.e. only one variable), then it is known as a linear equation in one variable.

In this problem, we are to solve for y.

7x - 6y = 17

Step 1

Take 7x to the right hand side of the equation

-6y = 17 - 7x

Step 2

Divide both sides by the coefficient of y

-6y / -6 = (17 - 7x) / - 6

y = - (17 + 7x) / 6

the slope would be -2/3

step2. finding the b

put a desire point of x,y table for example (3,0)

0 = -2/3 × 3 + b

b would be 2

The interest that Zollicoffer will receive in one year is $52.50.

The formula that is used for calculating the interest will be:

Interest = principal × rate × time

In this case, Mrs. Zollicoffer’s bank pays 5 1/4% interest. She has $1,000 in the bank. The interest that she would receive in one year will be:

Interest = Principal × Rate × Time

Interest = 1000 × 5.25% × 1

Interest = $52.5

What is an exponential function?

The exponential function is one of the most important functions in mathematics (though it would have to admit that the linear function ranks even higher in importance). To form an exponential function, we let the independent variable be the exponent.

An exponential function is a function that usually takes the form f(x) = bˣ.

The exponential curve depends on the exponential function and it depends on the value of the x.

where;

b = base

ˣ = power

The general exponential function that models  the data given is:

[tex]y = ce^{kt}[/tex]

According to the (5,5c)

[tex]ce^{5k} = 5c\\\\e^{5k} = 5\\\\5k = ln5\\\\k = \frac{ln5}{5} \\\\k = 0.32[/tex]

The two true options are A and D

The two options that are true about the graph that represents this real-world scenario are;

All the t values must be positive, and a viable solution is (10, 50). Hence, the correct option for this question is A and D.

Plotting the data in the graph is advantageous because it gives a visual presentation of the data and makes it easy to observe and forecast the large data set in a short time.

In the case of this question, the temperature is directly reliant on the c number of cricket chirps heard in 14 seconds. Therefore, if all the c values must be positive integers, the values of t must also be positive numbers.

t = c + 40

Because 10 is a positive integer, it is a possible c value

If c = 10

t = 40 + 10

t = 50

A viable solution (10, 50) represents the values of c and t, respectively, to predict the data more accurately and with validity.

Therefore, the correct option for this question is A and D.

Step-by-step explanation:

To convert 186283 miles per second to feet per hour, we need to first convert the distance from miles to feet. There are 5280 feet in a mile, so 186283 miles is equal to 186283 * 5280 = 9,839,784,000 feet.

We also need to convert the time from seconds to hours. There are 3600 seconds in an hour, so 186283 seconds is equal to 186283 / 3600 = 51.8 hours.

Therefore, 186283 miles per second is equal to 9,839,784,000 feet per 51.8 hours, or approximately 188,822,900 feet per hour. This is the final answer.

The volume expression for the box is 1.728lwh and it means that the volume increases by 72.8%

The complete question is added at the end of this solution

From the question, we have the following parameters that can be used in our computation:

Length = l

Width = w

Height = h

The volume of a box can be calculated using

Volume = lwh

Rewrite the volume equation as

v = lwh

When the dimensions of the box are increased by 20%, we have the following expressions

Length = 1.2l

Width = 1.2w

Height = 1.2h

So, the new volume is

V = 1.2l * 1.2w * 1.2h

Evaluate

V = 1.728lwh

Hence, the expression is 1.728lwh

The figure is moved 5 spaces left that would be a rule of x -5.

The y value tells how many units to move up or down.  Up would be addition and down would be subtraction.  In this case, we are moving the figure down one unit so the rule would be y - 1

Answer: $13.50

Step-by-step explanation:

It will cost Miguel $13.50 to send 6 small packages and 1 large package. To find the total cost, we can first calculate the cost of sending the small packages by multiplying the cost per small package by the number of small packages: 2.20 * 6 = $<<2.20*6=13.20>>13.20

We can then add the cost of the large package to find the total cost: 13.20 + 3.90 = $<<13.20+3.90=17.10>>17.10.

Therefore, it will cost Miguel $17.10 to send 6 small packages and 1 large package.

After solving the equations, the value obtained for x and y will be equal to  (-1, 1).

Mathematical expressions with two algebraic symbols on either side of the equal (=) sign are called equations.

This relationship is illustrated by the left and right expressions being equal. The left-hand side equals the right-hand side is a basic, straightforward equation.

As per the given equations in the question,

y = 2x + 3     (i)

y = -x            (ii)

Substitute equation (ii) in (i)

-x = 2x + 3

-x - 2x = 3

-3x = 3

x = -3/3

x = -1

Step-by-step explanation:

There are a total of 2^10 = 1024 possible outcomes for a coin flipped 10 times. Out of these, there are only 10 outcomes that have exactly 4 tails and start and end with different faces.

To count the number of outcomes with 4 tails, we can use the binomial coefficient formula: n choose k = n!/(k! * (n-k)!), where n is the total number of flips (10 in this case) and k is the number of tails (4 in this case). This gives us 10 choose 4 = 10!/ (4! * 6!) = 210 outcomes with 4 tails.

To count the number of outcomes that start and end with different faces, we can consider the first and last flips separately. The first flip can be either heads or tails and the last flip can also be either heads or tails, for a total of 2 * 2 = 4 possibilities.

Thus, there are a total of 210 * 4 = 840 outcomes that have exactly 4 tails and start and end with different faces. However, there are two outcomes (THTHTHTHTHT and TTHTHTHTHTH) that are counted twice in this total, so we need to subtract these from the total to get the correct number of outcomes. This gives us 840 - 2 = 838 outcomes.

Finally, we need to subtract the two outcomes that start and end with the same face (HHHHHHHHTH and THHHHHHHHH). This gives us a total of 838 - 2 = 836 outcomes.

Therefore, there are a total of 836 outcomes that have exactly 4 tails and start and end with different faces out of a total of 1024 possible outcomes.

What is a statement?

A statement in mathematics is a declarative utterance that can only be either true or false. A proposal is another name for a statement. It's important that there be no ambiguity. A sentence can only be true or untrue and not both for it to be a statement.

Given that:

Martina used the rule “Add 2.”

Sabrina used the rule “Add 6.”

The rule that Martina is follow is

M(n) = starting number + 2n

M(n) = 0 + 2n

M(n) = 2n

The rule that Sabrina is follow is

S(n) = starting number + 6n

S(n) = 0 + 6n

S(n) = 6n

S(n) = 3 × 2n

S(n) = 3 × S(n)
