Answer down below!

Step-by-step explanation:

The best way to find the slope of the line is first find a point that rests on the line on an exact point. This exact point is (-1,0)

Then, once you find that point, continue to use rise/run to find the slope.

In this case, it goes up one, and over one

So, your slope would be 1/1 or just 1.

(NOTE: IF YOU CONTINUE TO KEEP GOING ONE UP AND ONE OVER, IT WILL STILL GIVE YOU THE SAME SLOPE, BUT YOU WILL HAVE TO DO MORE WORK!!)

The total amount in the account after interest will be about $4525.63 .

In the fields of finance and economics, interest is the additional sum that is paid by a borrower or deposit-taking financial institution to a lender or depositor at a certain rate (the amount borrowed).

Interest when the principal is $4000 , time is 5 years and rate is 2.5%.

We know that from compound interest:

Amount = principal (1 + rate)ⁿ

Therefore

Amount = 4000 (1 +0.025)⁵

Amount = $4525.6328...

Amount ≈ $4525.63

Therefore adding interest the sum would be worth $657.51

If Mr. Giordano's drove 4.5 miles in 5 minutes and Mr. Baras drove 6.3 miles in 8 minutes, then the Mr. Giordano drove faster because the speed of the Mr. Giordano greater than Mr. Baras

Total distance traveled by the Mr. Giordano = 4.5 miles

The time taken = 5 minutes

Speed = Distance / Time

Speed = 4.5/5

= 0.9 miles per minutes

Total distance traveled by the Mr. Baras = 6.3 miles

The time taken = 8 minutes

Speed = Distance / Time

Speed = 6.3/8

= 0.78 miles per minutes

Hence, if Mr. Giordano's drove 4.5 miles in 5 minutes and Mr. Baras drove 6.3 miles in 8 minutes, then the Mr. Giordano drove faster because the speed of the Mr. Giordano greater than Mr. Baras

The students will earn $82.5 if they sell all the bottles of liquid soap.

The formula of the unitary method is to find the value of a single unit and then multiply the value of a single unit to the number of units to get the necessary value.

Given that,

Total amount of liquid soap prepared by the students for a craft fair =

97.5 ounces

Weight of each bottle in which students poured the soap = 6.5 ounces

Let us first calculate the number of bottles, each contains 6.5 ounces of soap from 97.5 ounces of soap.

So, Number of bottles = [tex]\frac{97.5}{6.5}[/tex] = 15

It means, 15 bottles are prepared which contains 6.5 ounces of soap from 97.5 ounces of soap.

The amount at which each bottle is sold = $5.50

The total amount earned by selling all the bottles of liquid soap = 15×$5.50 = $82.5

Hence, The students will earn $82.5 if they sell all the bottles of liquid soap.

The value of y-coordinate from the given information is 36.

Given that, the water level rises 12 centimeters every 7 minutes and you record the data point of ​(21​, y).

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

According to the question the water rises 12 cm every 7 minutes. Taking x to represent the time in minutes and y to represent the rise in cm then, find the rise y in time x as;

7 minutes = 12 cm

1 minute

(1×12)/7 = 12/7

Hence in 1 minute, the rise is 12/7 cm

Thus in 11 minutes, the rise will be ;

21  × 12/7 = 3 × 12 = 36 cm

So, (x, y) will be (21, 36)

Therefore, the value of y-coordinate from the given information is 36.

The equation of line which is parallel and the line perpendicular to the given line passing through the given point as y = 2x + 7; (0, 1) is y = (-1/2)x + 1.

What is perpendicular line?

The definition of a perpendicular line in geometry is a pair of lines that meet or intersect at right angles (90°). The Latin word "perpendicularis," which denotes a plumb line, is where the word "perpendicular" first appeared.

[tex](y-1) = -\frac{1}{2} (x-0)[/tex]The equation of the line given in the question is:

y = 2x+7

On comparing with the equation y = mx + a

where, m is slope

we get slope of the line as m = 2.

Since the line we have to find is parallel to given line, they have equal slope.

Now, we know that the equation of perpendicular line is given by:

[tex](y-y_1) = -\frac{1}{m} (x-x_1)[/tex]

given points are (0,2) which is represented by (x1,y1)

On putting the value in the equation, we get

[tex](y - 1) = -\frac{1}{2}(x-0)[/tex]

After simplifying it we get the final equation as:

[tex]y = -\frac{1}{2} x + 1[/tex]

Above equation is the equation of line which is parallel and the line perpendicular to the given line passing through the given point as y = 2x + 7; (0, 1).

The exact Population of the city Y in 2010 was 160,000.

Step-by-step explanation:

Given that,

1. In the year 2015, the populations of City X and City Y were equal.

2. City X population is increased by 20% and City Y population is decreased by 10% from 2010 to 2015.

3. Also, the population of City X was 120,000 in 2010

With the given data, calculation goes like this,

The population of City X in 2010 is 120000

Population Increased by 20% till 2015,

                = 120000×120/100

                = 144000

As Population of city Xand Y are same,

Population of city Y in 2015 would be 144000.

Population of Y in 2010 was decreased by 10%,

                = 144000×100/90

                =160000

Therefore, the Population of city Y in 2010 was 160,000.

Step-by-step explanation:

The probability that the sample is less than 8.42 is 0.0029 or 0.29%.

Using the normal distribution and the central limit theorem,

The mean is μ = 8.5

The standard deviation is σ = 0.22 .

A sample of 37 is taken, hence n = 37, s = 0.22/√37 i.e. s = 0.0362

The probability that the sample average is LESS than 8.40 is the p-value of Z when X = 8.4, hence:

Z = X - μ/σ

Z = 8.4 - 8.5/0.0362

Z = 2.76

Z = -2.76 has a p-value 0.0029

0.0029 = 0.29% probability that the sample average is LESS than 8.40.

A woman purchased 12 little frames and 10 large frames.

We create an algebraic equation in this question.

An algebraic equation is a mathematical statement that makes two expressions equal to one another.

In most circumstances, an algebraic equation consists of a variable, coefficients, and constants.

According to question, the equation will be

Let x = large frame

     y = small frame

x + y = 22                                     ---(1)

10x + 5y = 160                             ---(2)

Now, solve the eq(1) and eq(2),

we get, x = 10

     and, y = 12

If you want to cross-check you can do like that,

large frame price = $10

and, x = 10 (means 10 large frames women bought)

so the price will be = $ 10 * 10

                                = $100

Now, for the small frame price = $5

and, y = 12 (means 10 large frames women bought)

so the price will be = 12 * $5

                              = $60

Now total price is given = $160

and if we add both the prices of large and small frames = $100 + $60

we get, same as total price =  $160                                                                                              

Therefore, we can say that woman bought 10 large frames and 12 small frames.

Answer:

Step-by-step explanation:

 Remove the parenthesis by multiplying each term of (y+ 4) by (-3) and  multiplying each term of (2y - 2) by 4

 -3(y + 4) + 4(2y - 2) = (-3)*y + (-3)*4 + 4*2y - 2*4

                                = -3y - 12 + 8y - 8

                               = -3y + 8y  -12 - 8

Comparison symbol makes each inequality statement true is −6.809< −6.812.

The given numbers are −6.809 and −6.812.

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

Comparing decimals involves starting with the digits having the highest place value, just like when comparing other whole numbers. We begin the comparison by putting the provided decimal numbers in a place value table. We move on to the digits in the next place to the right if the digits on the biggest place value match. Up till the digits that are different are reached, we continue comparing digits.

−6.809< −6.812

|−6.809|>|−6.812|
