21. Six more than three times a number is equal to the number itself. Write the equation and find the number.

Answers

Answer 1

Answer:

-3

Step-by-step explanation:

6 + (six more) 3x (3 times a number) = x (is equal to the number)

6 + 3x = x

6 + 2x = 0

2x = -6

x = -3

What is the equation of a line perpendicular to y = -3x + 4 that passes through the point (-1, 6)?

Answers

Answer:

Equation is 3y = x + 19

Step-by-step explanation:

General equation:

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

For slope, m:

[tex]m_{1} \times m_{2} = - 1[/tex]

but m1 is -3:

[tex] - 3m_{2} = - 1 \\ m_{2} = \frac{1}{3} [/tex]

For y-intercept, c:

[tex]y = mx + c \\ 6 = ( - 1 \times \frac{1}{3} ) + c \\ \\ c = 6 + \frac{1}{3} \\ \\ c = \frac{19}{3} [/tex]

equation:

[tex]{ \sf{y = \frac{1}{3}x + \frac{19}{3} }} \\ \\ 3y = x + 19[/tex]

h = y

Answer:

It is 3.14x²y

Step-by-step explanation:

formular:

[tex]{ \bf{V = \pi {r}^{2} h}}[/tex]

r is radius, r = 2x/2 = x

h is height, h = y

The number of sweets s that each friend gets is the
number of sweets in a box n divided by the number of
friends f the sweets are shared between. Enter a formula
for the number of sweets each friend gets and enter the
number of sweets each friend gets if there are 54 sweets
and 6 friends.

Answers

Answer: 9 sweets/friend

Step-by-step explanation:

s = Number of sweets per friend

n = Number of sweets in a box = 54

f = Number of friends = 6

formula for the number of sweets each friend gets is as follows:

                                n/f = s

Therefore substituting in formula for n=54 and f=6

                                  54/6 = 9 sweets per friend

Find k such that 16x2 – 8 /3x+k=0 has a repeated real solution.

Answers

Answer:

k = [tex]\frac{1}{9}[/tex]

Step-by-step explanation:

Using the discriminant

Δ = b² - 4ac

For a repeated real solution then

b² - 4ac = 0

Given

16x² - [tex]\frac{8}{3}[/tex] x + k = 0

with a = 16, b = - [tex]\frac{8}{3}[/tex] , c = k

(- [tex]\frac{8}{3}[/tex] )² - ( 4 × 16 × k) = 0

[tex]\frac{64}{9}[/tex] - 64k = 0 ( subtract [tex]\frac{64}{9}[/tex] from both sides )

- 64k = - [tex]\frac{64}{9}[/tex] ( divide both sides by - 64 )

k = [tex]\frac{1}{9}[/tex]

Find AC someone help please. If you can please include steps

Answers

Answer:

AC = 15

Step-by-step explanation:

AC is the entire line split into two segments; AB and BC

We are given that AB = 8 and BC = 2x + 25 so we can combine these two and set them equal to AC ( = x + 24)

x + 24 = 8 + 2x + 25

Combine like terms and isolate x

x + 24 = 2x + 33

-9 = x

Now plug in -9 for x in the equation for line AC

(-9) + 24 = 15

A: y = 17x

Step-by-step explanation:

Answer:

21 is A

22 is B

Step-by-step explanation:

51 / 3 = 17, which is the cost of 1 hour.  That means, in order to find the charge (y), you need to multiply the # of hours (x) by 17.  Equation A represents this correctly.  

Now that we know this, for question 22, if someone rented a machine for 3.5 hours, to find the charge, multiply 3.5 by 17.  This gives you 59.50.

I’m crying rn I need helppp (number 4 ignore the rest) -1/2 to be left alone like without the x and what happened to the 5/2??

Answers

Step-by-step explanation:

The parallel line will have an equation of the form

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

We solve for b by plugging in the values of the point (3, -4):

[tex]-4 = -\dfrac{1}{2}(3) + b[/tex]

[tex]\Rightarrow -8 = -3 + 2b[/tex]

Solving for b, we get

[tex]b = -\dfrac{5}{2}[/tex]

Therefore, the equation of the line parallel to 2x + 4y = 10 is

[tex]y = -\dfrac{1}{2}x -\dfrac{5}{2}[/tex]

In standard form we can write

[tex]x + 2y = -5[/tex] or [tex]2x + 4y = -10[/tex]
