Equation #1: 3x + 11 = 11
Equation #2: 3(x - 3) = 45

Answers

Answer 1

Step-by-step explanation:

Given that,

Two equations,

3x + 11 = 11 .....(1)

And

3(x - 3) = 45

or

3x-9=45 ....(2)

Subtract 11 on both sides of equation (1).

3x + 11-11 = 11-11

3x=0

x = 0

Add 9 to both sides of equation (2)

3x-9+9=45+9

3x = 54

x = 18

Hence, the solution of equation (1) is x=0 and form equation (2) x = 18.

Can someone answer these two questions I submitted a photo of them it’s worth 50 points

Answers

Answer:

Step-by-step explanation:

1). Let the equation of the line is,

  y = mx + b

  Here, m = slope of the line

  b = y-intercept

  Slope of a line passing through two points,

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

  We take two points from the table given (-3, -19) and (0, -1)

  m = [tex]\frac{-19+1}{-3-0}[/tex]

  m = 6

  y - intercept 'b' = -1 [For x = 0]

  Therefore, equation of the line will be,

  y = 6x - 1

2). Equation of a line passing through a point (x', y') is,

   y - y' = m(x - x')

   Slope of the line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is,

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

   We take two points from the given table as (2, 12) and (3, 18).

   Slope of the line passing through these points will be

   m = [tex]\frac{18-12}{3-2}[/tex] = 6

   Equation of the line passing through (2, 12) will be,

   y - 12 = 6(x - 2)

   y = 6x - 12 + 12

   y = 6x

By using a graphing tool we can graph these lines representing the tables.

2x+y=17 in slope intercept form

Answers

Answer:

y=-2x+17

Step-by-step explanation:

So the problem is 2x+y=17, we know that slope intercept form is y=mx+b where m is the slope and b is the y-int.

All you have to do is isolate the y.

2x+y=17

-2x on both sides so you can leave the y alone.

y=-2x+17 should be the answer. Hope this helps!

A cell phone normally sells for $500, but it is marked down 30% and you have a coupon for an additional 15% off. How much would it cost you to purchase the cell phone?

Answers

Answer:

$275

Step-by-step explanation:

30% + 15%=45%

45% of 500 is 225, because 500 x 0.45=225. Then subtract the discount from the total, 500 - 225, and you get 275

Answers

Step-by-step explanation:

[tex]v = {x}^{3} \\ {v}^{2} + 3v - 5 = 0 \\ [/tex]

Solving this equation using the quadratic formula, we get two real solutions :

1.1926 or -4.1926

Now we know the values of v , we can calculate x since x is ∛ v

[tex] {x}^{6} + 3 {x}^{3} - 5 = 0[/tex]

[tex]x = \sqrt[3]{1.1926} = 1.0605 \\ x = \sqrt[3]{ - 4.1926} = - 1.6125[/tex]

On that day the bakery gave away a total of 29 free gingerbread man cookies what was the total number of free candy canes the bakery gave away on that day show how or explore how you got your answer

Answers

Answer: 19 people

Step-by-step explanation:

If every 4th customer received a free gingerbread man cookie and 29 cookies were given away then the number of customers that came were:

= 4 * 29

= 116 customers

Because 116 customers came, they were able to give 29 cookies by giving one to every 4th customer.

If there were 116 customers, the number of customers who got the free candy canes would be:

= 116/6

= 19.3

= 19 people

If f(x) = 5 + 4(x - 4)?,
what is f(7)?

Answers

Answer:

Let's solve for f.

x=5+4(x−4)f(7)

Step 1: Flip the equation.

28fx−112f+5=x

Step 2: Add -5 to both sides.

28fx−112f+5+−5=x+−5

28fx−112f=x−5

Step 3: Factor out variable f.

f(28x−112)=x−5

Step 4: Divide both sides by 28x-112.

f(28x−112)28x−112=x−528x−112

f=x−528x−112

Answer:

f=x−528x−112
