If a shirt cost 9.99, but there was a sale that said 15% of the original price, how much was the shirt?

Answer: 4

Step-by-Step Explanation: When written in slope-intercept form, the equation becomes y = 4x - 2; the basic structure of this formula is y=mx+b, where m is the slope and b is the y-intercept.

Knowing this information, we can also figure out the slope and y-intercept. 4, or m, is the slope of the proposed line.

1/2(2x-6)= -6

Step-by-step explanation:

Multiply the two sides by the equation 2

2x-6=12

move the constant to the right hand side change sign

2x = -12 + 6

calculate the sum

2x= -6

Divide the 2 sides by 2

x= -3

Answer:

To start off those are horrible stats, 24 made out of 80, sooo sad :-(

Anyways for your answer you want to look at how many shot attemps

were made by all 3 players

Sue = 80

Janice = 35

Maria = 145

80 + 35 + 145 = 260

260 represent how many shots were taken altogether, which is very important.

From here calculate how many shots were made then divide total shots made with total shots taken.

Hope this helps :)

Step-by-step explanation:

The line a is an illustration of a linear function

From the complete figure, we have the following points on line a

(x,y) = (0,2) and (2,4)

The slope (m) is calculated using:

[tex]m = \frac{y_2 - y_1}{x_2 -x_1}[/tex]

This gives

[tex]m = \frac{4 - 2}{2 - 0}[/tex]

Evaluate

m = 1

Hence, the slope of line a is 1

This is calculated as

y = m(x - x1) + y1

So, we have:

y = (x - 0) + 2

Evaluate the difference and the product

y = x + 2

Hence, the equation of the line a is y = x + 2

Step-by-step explanation:

[tex]\frac{7-4}{5-2}=\frac{3}{3}= 1[/tex]

Answer:

the slope is 1

Step-by-step explanation:

It's given that a line passes through the points,

A = (2,4)

B = (5,7)

Clearly, we have to find the slope of the line.

Let, the slope of line is 'm'

We know that, if a line passes through two points (a,b) and (c,d) ,

Then, the slope of the line is given by formula,

Therefore, We get,

Hence, slope of line = 1

Complete question is;

Find the dimensions or, the square or circle. Area = 64π in²

Answer:

r = 8 inches

Step-by-step explanation:

We know that formula for area of a circle is; A = πr²

Where r is radius.

We are given Area as 64π in²

Thus;

πr² = 64π

π will cancel out to give;

r² = 64

r = √64

r = 8 inches

Answer: n-15

Step-by-step explanation: This is because since he is going 15 miles slower than Micale, your write n-15

Answer:

n-15

Step-by-step explanation:

We don't know how fast Micale is traveling, so we use "n". If Joshua is traveling at 15 mph less than Micale, but we don't know how fast Joshua is going, we use n-15.

Answer:

The answer is -1,1

Step-by-step explanation:

Answer:

x = 3

Step-by-step explanation:

-4x - 5 + 2x = -11

step 1 (group like terms)

-4x + 2x = -11 + 5

step 2 (evaluate)

(left hand side (L.H.S) of the '=' sign)

-4x + 2x = -2x

(right hand side (R.H.S) of the '=' sign)

-11 + 5 = -6

step 3(Equate L. H. S to R. H. S) and evaluate

-2x = -6

Divide both sides by the coefficient of 'x' ie.(-2)

-2x/-2 = -6/-2

x =3

Note: when a negative number divides a negative number the result is positive.

Answer:

4.23

Step-by-step explanation:

When rounding to the nearest hundredth, the number 4.231 becomes 4.231.

To round 4.231 to the nearest hundredth, we look at the digit in the thousandth place, which is 3.

Now, If the digit to the right is less than 5, you simply drop all the digits to the right and keep the desired decimal place unchanged.

If the digit to the right is 5 or greater, you round up the desired decimal place by increasing it by one. Drop all the digits to the right.

Since 3 is less than 5, we do not need to round up.

Therefore, the number remains the same.

Rounded to the nearest hundredth, 4.231 remains as 4.231.

Answer:

21.5 feet

Step-by-step explanation:

d = Distance of the bottom of the tower to the point of observation

x = Height of the top section of the tower

a = Height of bottom section

b = Total height of tower

[tex]\tan28^{\circ}=\dfrac{a}{d}\\\Rightarrow a=d\tan28^{\circ}\\\Rightarrow a=70\tan28^{\circ}[/tex]

[tex]\tan40^{\circ}=\dfrac{b}{d}\\\Rightarrow b=d\tan40^{\circ}\\\Rightarrow b=70\tan40^{\circ}[/tex]

The height of the top section of the tower is 21.5 feet.

Answer:

A and B are equivalent to -96x + 120

Step-by-step explanation:

-96x + 120

A. 8 (-12x + 15)

8 * -12x = -96x

8 * 15 = 120

8 (-12x + 15) = -96x + 120

-96x + 120 = -96x + 120

Equivalent

B. -12 (8x - 10)

-12 * 8x = -96x

-12 * -10 = 120

-12 (8x - 10) = -96x + 120

-96x + 120 = -96x + 120

Equivalent

C. -8 (12x + 15)

-8 * 12x = -96x

-8 * 15 = -120

-8 (12x + 15) = -96x-120

-96x + 120 ≠ -96x - 120

Answer:

Step-by-step explanation:

First solve for the common ratio:

[tex]\frac{30}{180} = \frac{1}{6} 6 \\ \\\frac{5}{30} = \frac{1}{6}[/tex]

Use the geometric summation equation to solve for sum:

[tex]a(\frac{(1-r^{n} )}{(1-r)})\\180(\frac{(1-\frac{1}{6} ^{6}) }{(1-\frac{1}{6} )}) = \frac{46655}{216} = 216[/tex]

The sum of the first 6 terms of the following series is 540.

A geometric series is the sum of an infinite number of terms that have a constant ratio between successive terms.

The sum of the terms of the geometric sequnece is given by;

[tex]\rm S_n=\dfrac{a(1-r^n)}{1-r}[/tex]

The common ratio of the sequence is;

[tex]\rm \dfrac{a_2}{a_1}=\dfrac{30}{180}=\dfrac{1}{6}\\\\ \dfrac{a_2}{a_1}=\dfrac{5}{30}=\dfrac{1}{6}\\\\[/tex]

The sum of the first 6 terms of the following series is;

[tex]\rm S_n=\dfrac{a(1-r^n)}{1-r}\\\\\rm S_6=\dfrac{180(1-1/6^6)}{1-1/6}\\\\ S_6=\dfrac{180\times 0.99}{5/6}\\\\S_6=\dfrac{180\times 0.99}{0.33}\\\\S_6=\dfrac{178.2}{0.33}\\\\S_6=540\\[/tex]

Answer:

2 1/3 is the improper fraction of 7/3

Answer: I believe it is the X axis. <3

Step-by-step explanation:

Answer:

-3/5

(0,4)

Step-by-step explanation:

The slope, or m, is the change in y over the change in x. So to find m calculate how much y changes then divide that by how much the x value changes. On the table, the y-values decrease by 3 each time, and the x-values increase by 5 units each time. This means m must equal -3/5.

The y-intercept is when the line crosses over the y-axis. This will also be when x=o. So to find the intercept find when x=0; in this case, when x=0, y=4. This means the intercept is (0,4).
