Answer:

Step-by-step explanation:

The question is incomplete. Here is the complete answer.

A given line has the equation 2x + 12y = −1.

What is the equation, in slope-intercept form, of the line that is perpendicular to the given line and passes through the point (0, 9)?

General formula of equation of a line is exspressed as y = mx+c

m = gradient or slope  

c = intercept

Step 1: we need to first get the slope of the given equation of a line by rewriting the equation in standard form y = mx+c

2x + 12y = −1

12y = -1-2x

y = -1/12-2x/12

y = -1/6 x - 1/12

From the equation above, it can be seen that the slope (m) of tghe line is -1/6.

Since both lines are perpendicular, the slope of the unknown line will be;

M = -1/m

M = -1/(-1/6)

M = 6

Step 2: We will find the intercept c by substituting the point (0,9) and the slope into the equation y = mx+c

9 = 6(0)+ c

c = 9

Stwp 3: We will find the equation of the line perpendicular to the given line by substituting the value of m and c into the equation y = mx+c

y = 6x+9

y-6x = 9

The equation in slope-intercept form, of the line that is perpendicular to the given line and passes through the point (0, 9) is y-6x = 9

Answer:

y-6x=9

Answer:

She can swin 3.6 km in 1 hour using freestyle.

Step-by-step explanation:

If she can swin 0.3 kilometers in 10 minutes or 1/6 hours using backstroke, then her speed on that style is:

[tex]v_{backstroke} = \frac{0.3}{\frac{1}{6}} = 0.3*6 = 1.8 \text{ } \frac{\text{km}}{\text{h}}[/tex]

If she can swim twice the distance in the same time for freestyle, then her speed on that is twice the one in backstroke. Therefore, her speed on freestyle is:

[tex]v_{freestyle} = 2*v_{backstroke} = 2*1.8 = 3.6 \text{ } \frac{\text{km}}{\text{h}}[/tex]

Since her speed in freestyle is 3.6 km per hour, this means that she can swim a total of 3.6 km in one hour.

Answer:

11 < √131 < 12

Step-by-step explanation:

121 and 144 are perfect squares.

11² = 121

12² = 144

√131 = 11.445523

√131 lies between 11 and 12, which are consecutive integers.

Answer:

x = -103/70 or approximately -1.47

Step-by-step explanation:

First, what I would do is get rid of the denominator, 2. You do this by perming the inverse operation to both sides, so you multiply both sides by 2.

Now your equation is: 70(4x+6) = 8

Next what I did was distribute the 70 inside the parentheses:

280x + 420 = 8.

Then you subtract 420 from both sides:

280x = -412

To get x by itself, you have to divide both sides by 280:

x= -412/280 , which simplifies to -103/70 , or can be written as an approximation of -1.47 (rounded to nearest hundredth)

This number looks nasty, but I checked my work so it should be right :)

Answer:

x=  −103 /70

Step-by-step explanation:

Answer:

see explanation

Step-by-step explanation:

∠ 1 and ∠ 2 are adjacent angles and supplementary, thus

∠ 2 = 180° - ∠ 1 = 180° - 110° = 70°

--------------------------------------------------

The chord- chord angle 3 is half the sum of the measures of the arcs intercepted by the angle and its vertical angle, thus

∠ 3 = [tex]\frac{1}{2}[/tex] (100 + 60)° = 0.5 × 160° = 80°

∠ 3 and ∠ 4 are adjacent angles and supplementary, thus

∠ 4 = 180° - 80° = 100°

Thus

Angle    Value

   1           110

   2            70

   3             80

   4            100

V = 10.5 ft³

Step-by-step explanation:

Volume formula: length x width x height

We are given all 3, so all we have to do is multiply them all together, When we plug it into the calc, we should get 21/2 or 10.5 ft³ as our answer.

Answer:

Christian made $191.25 and Kenneth made $127.50 each.

Step-by-step explanation:

With each dog, you multiply how many dogs with the amount of cash they get each dog.

Christian: 15x12.75= $191.25

Kenneth: 10x12.75= $127.50

So you just multiply the amount of dogs with money :)

Answer:

d

Step-by-step explanation:

-10=-5*2;        4=2*2

l-10+3l= 7;      l4+3l=7

==================================================

Work Shown:

|2x+3| = 7 means either 2x+3 = 7 or 2x+3 = -7

Solve each for x

2x+3 = 7

2x = 7-3

2x = 4

x = 4/2

x = 2 is one solution

Repeat for the other equation

2x+3 = -7

2x = -7-3

2x = -10

x = -10/2

x = -5 is the other solution

------

Each solution can be checked by plugging it back into the original equation and simplifying. You should get the same number on both sides

For instance, checking x = -5 leads to

|2x+3| = 7

|2(-5)+3| = 7

|-10+3| = 7

|-7| = 7

7 = 7

Which confirms x = -5. I'll let you check x = 2.

Answer:

D

Step-by-step explanation:

You have 2 5 12 13 right triangles.

x = 2 * 5

x = 10

Answer:

D. [tex]x=10[/tex]

Step-by-step explanation:

You can use the Pythagorean Theorem, [tex]a^2+b^2=c^2[/tex], where a and b are the legs and c is the hypotenuse.

[tex]12^2+b^2=13^2\\144+b^2=169[/tex]

Subtract 144 from both sides

[tex]b^2=25[/tex]

Square root both sides

[tex]b=5[/tex]

[tex]2b=x\\b=5\\x=10[/tex]

Answer:

True

Step-by-step explanation:

We need to verify whether 15 and 20 are the correct solution to the rule of "The difference between the 2 number is 5 and the number are in the ratio 3 : 4". Let's see,

First rule → The difference between the 2 numbers is 5

20 - 15 = 5 ⇒ Correct

Second rule → The numbers are in the ratio 3 : 4

15 : 20 ( ÷ 5 to both ratio's ) 3 : 4 ⇒ Correct

Answer:

25/8

Step-by-step explanation:

Given That:

R = 8x+4y

X= 8

R = 30.

So, 8 x 8 +4y = 30

Simplify, Rearrange and solve.

64 + 4y = 30

4y = 30/64 = 15/32

y = 15/32 divided by 4

y = 15 / 32 x 1/4

y = 15/(32 x 4) = 15/128

Complete question is;

raj writes a polynomial expression in standard form using one variable, a, that has 4 terms and is degree 5. Nicole writes a polynomial expression in standard form using one variable, a, that has 3 terms and is degree 2. Raj and Nicole’s polynomial expressions are added to create a sum, written in standard form. What can you determine about the degree of the sum? The sum will be degree . What can you determine about the number of terms of the sum? The maximum number of terms of the sum is , but it could be less.

Answer:

Degree: 5

Maximum number of terms: 6 or could less

Step-by-step explanation:

We are told that Raj writes a polynomial expression in standard form using one variable, a, that has 4 terms and is degree 5. So let this polynomial be: Aa^(5) + Ba³ + Ca + D

Also, we're told that: Nicole writes a polynomial expression in standard form using one variable, a, that has 3 terms and is degree 2.

The polynomial is: Ea² + Fa + G

If we add both polynomials we, we will get;

Aa^(5) + Ba³ + Ca + D + Ea² + Fa + G

Rearranging terms to give;

Aa^(5) + Ba³ + Ea² + Ca + Fa + D + G

Collecting like terms to give;

Aa^(5) + Ba³ + Ea² + a(C + F) + (D + G)

So this is now a 5 degree polynomial.

So the new sum will have a degree of 5.

Also, as seen in the above steps, the maximum number of terms could be 6 or less.

Answer:

D.) If soccer balls are sold for $2.05 or $14.61 each, the store will break even but will not make a profit.

Step-by-step explanation:

Let us assume x = selling price of each soccer ball

y = daily profit earned from selling of soccer balls

Given that

Y= [tex]-6x^2+100x-180[/tex]

where,

a = -6

b = 100

c = -180

Now we have to applied the formula which is as follows

x [tex]= \frac{-b\pm\sqrt{b^2-4ac}}{2a}$[/tex]

[tex]= \frac{-100\pm\sqrt{100^2-4\times -6\times -180}}{2\times -6}$[/tex]

[tex]= \frac{-100\pm\sqrt{10,000 - 4,320}}{-12}$[/tex]

[tex]= \frac{-100\pm\sqrt{5.680}}{-12}$[/tex]

[tex]= \frac{-100 + 75.3658}{-12}$[/tex]

[tex]= \frac{24.6342}{-12}[/tex]

x^1 = -2.05285

Now

x^2  [tex]= \frac{-100 - 75.3658}{-12}$[/tex]

[tex]= \frac{- 175.3658}{-12}[/tex]

x^2 = 14.6138

Based on this the option D is most appropriate as per the given situation

PLEASE MARK ME AS BRAINLIEST!!!

8, 3, -2, -7

basically

you have to figure how to get from one term to the other. so in this case, to get from 8 to 3, you have to minus 5. and same again to get from 3 to -2, you again have to -5.

so the first past of the answer is -5n.

then after that, you have to figure out how to get from -5, to the first term of your sequence. so you have to add 13, in this case.

your answer would then be

Answer:

-5x + 13

Step-by-step explanation:

to find the nth term, you must find the difference between each consecutive given terms.

So,

8 and 3 = -5

3 and -2 = -5

-2 and -7 = -5

This is the m in the equation mn+c

c is the value you must add to -5n when n is 1

Hope this helps
