Given:

A line is perpendicular to the line [tex]y=\dfrac{7}{2}x-13[/tex].

The line passes through the x-axis at 21.

To find:

The equation of the line in slope intercept form.

Solution:

The slope intercept form of a line is:

[tex]y=mx+b[/tex]

Where, m is the slope and b is the y-intercept.

The given line is:

[tex]y=\dfrac{7}{2}x-13[/tex]

So, the slope of this line is [tex]\dfrac{7}{2}[/tex].

The product of slopes of two perpendicular lines is -1.

Let m be the slope of required line. Then the slope of the required line is:

[tex]m\times \dfrac{7}{2}=-1[/tex]

[tex]m=-\dfrac{2}{7}[/tex]

The line passes through the x-axis at 21. It means the line passes through the point (21,0). So, the equation of the line is:

[tex]y-y_1=m(x-x_1)[/tex]

[tex]y-0=-\dfrac{2}{7}(x-21)[/tex]

[tex]y=-\dfrac{2}{7}(x)-\dfrac{2}{7}(-21)[/tex]

[tex]y=-\dfrac{2}{7}x+6[/tex]

Therefore, the equation of the required line is [tex]y=-\dfrac{2}{7}x+6[/tex].

Step-by-step explanation:

Answer:

if u don't want them to have your insta/snap, tell them that you don't like sharing them. I just wouldn't respond after that

If they are bothering you say "Thank you for being nice to me, I am going to say this in the most the nicest way possible, but you're kind of bothering me right now. If you keep messaging me/ bothering me I'm going to have to block you" or you could say "Please stop asking me for my insta/snap if you keep asking me I am going to have to block you. Thank you have a nice day :)"

you could say something like that

Answer:

20

Step-by-step explanation:

Pythagorean Theorem: a^2 + b^2 = c^2

21^2 + b^2 = 29^2

441 + b^2 = 841

Subtract 441 on both sides to get b^2 = 400

Take the square root of both sides to get b = 20

Answer:

Proportion of female older Than 60 in country A is not more than the proportion of female older Than 60 in country B.

Step-by-step explanation:

From. The plot given :

We could approximate the proportion of females older than 60 as follows _

COUNTRY A :

60 - 69 = 0.105

70 - 79 = 0.065

80 - 89 = 0.038

90+ = 0.01

Total = About 0.218

COUNTRY B :

60 - 69 = 0.14

70 - 79 = 0.11

80 - 89 = 0.07

90+ = 0.02

Total = About 0.34

From the estimated proportion, the proportion of females on country B is more than the proportion in country A.

Answer:

x = 23

Step-by-step explanation:

Remember, angles in a triangle add up to equal 180

That being said we can create an equation to solve for x

180 = 110 + 35 + x + 12

now we solve for x

step 1: combine like terms

110 + 35 + 12 = 157

now we have 180 = 157 + x

step 2 subtract 157 from each side

180 - 157 = 23

157  - 157 cancels out

we're left with x = 23

Answer:

35.8

Step-by-step explanation:

Triangle adds up to 360 degrees

5y+4y+3+y-1=360

10y+2=360

     -2   -2

10y=358

divided both sides by 1o

y=35.8

Answer:

square root of 34

Step-by-step explanation:

ok so S is for Squared

Cs= As+Bs

5s+3s= Cs

25+9=34

Cs=34

C= square root of 34

to get C we need to square root Cs

square root of 34

so C is 5.83

Answer:

{14, 47, 50}

Step-by-step explanation:

The three sides of a right triangle must satisfy

a² + b² = c², known as the Pythagorean Theorem. So let's put the pairs into the theorem.

20, 48, 52

a² + b² = c²

20² + 48² = 52²

400 + 2304 = 2704

2704 = 2704

20, 48, and 52 represent the three sides of a right triangle.

40, 75, 85

a² + b² = c²

40² + 75² = 85²

1600 + 5625 = 7225

7225 = 7225

40, 75, and 85 represent the three sides of a right triangle.

14, 47, 50

a² + b² = c²

14² + 47² = 50²

196 + 2209 = 2500

2405 ≠ 2500

14, 47, and 50 do NOT represent the three sides of a right triangle.

13, 84, 85

a² + b² = c²

13² + 84² = 85²

169 + 7056 = 7225

7225 = 7225

13, 84, and 85 represent the sides of a right triangle.

14, 47, and 50 do NOT represent the three sides of a right triangle, therefore making it your answer.

Answer:

In mathematics, the Pythagorean Theorem, or Pythagoras's Theorem, is a fundamental relation in Euclidean geometry among the three sides of any triangle.True

Answer:

3.25 per pound

Step-by-step explanation:

If 2 pounds = 6.50

then 1 pound = ?

Divide 6.50 and 2. You will get 3.25

so that is why the answer is 3.25 per pound.

Answer: $32.25

Step-by-step explanation:

Assuming this is compound interest, the value of the investment after a period of time can be calculated with the future value formula:

Value = Investment * ( 1 + rate) ^ no. of periods

Value ₄₀ = 2,000 * ( 1 + 0.04%)⁴⁰

Value ₄₀ = $2,032.25

Interest earned = Value at 40 years - Initial investment

= 2,032.25 - 2,000

= $32.25

Answer:

The area is 2,000 cm2

Step-by-step explanation:

The answer is that because Area is when you multiply the length times the width ( l x w ). The length is 40 cm and the width is 50 cm and when you multiply them, you will get 2,000 cm2.

Hope that helps. If you get it wrong, please let me know so I could check my work. Thank you and have a great rest of your day :) !

Answer:

[tex]\frac{-1}{2} <x<\frac{2}{3}[/tex]

Step-by-step explanation:

6x² - x - 2 < 0

6x² - 4x + 3x - 2 < 0

(6x² - 4x) + (3x - 2) < 0

2x(3x - 2) + (3x - 2) < 0

(3x - 2)(2x + 1) < 0

[tex]\left \{ {{3x - 2<0} \atop {2x + 1>0}} \right.[/tex]

Given:

The exponential function is:

[tex]y=190(1.471)^x[/tex]

To find:

The percentage of increase or decrease.

Solution:

The general exponential function is:

[tex]y=a(1+r)^x[/tex]                   ...(i)

Where, a is the initial value,t is the time period, r is the rate of increase if [tex]r>0[/tex] and r is the rate of decrease if [tex]r<0[/tex].

We have,

[tex]y=190(1.471)^x[/tex]

It can be written as:

[tex]y=190(1+0.471)^x[/tex]         ...(ii)

On comparing (i) and (ii), we get

[tex]r=0.471[/tex]

Since [tex]r>0[/tex], therefore the given function is an increasing function.

[tex]r\%=0.471\times 100[/tex]

[tex]r\%=47.1\%[/tex]

Therefore, the percentage of increase is 47.1%.

it should be like this

Answer:

a. =11+ 1

b. =4x+ (-7y) + (-5z) +6

c. (-3x) + (-8y) +(-4)+(-8/7z)

Step-by-step explanation:

a. 20 - 9 + 8 -7

=11+ 1  ( this is obtained by solving)

b. 4x - 7y - 5z + 6

=4x+ (-7y) + (-5z) +6

We multiply the negative sign with the positive sign to get a minus so the answer remains the same and the expression is written as an addition sum.

c. -3x - 8y - 4 - 8/7z

-[ 3x+8y+4+8/7z]

or

(-3x) + (-8y) +(-4) +(-8/7z)

The minus sign is taken as common leaving the expression with the plus only.

It can be written in the same manner as above, adding the negative terms so that the expression is written as a sum.

The expressions are a sum after the negative sign is marked with the terms. It shows that the negative terms are being added.
