Put the following equation of a line into slope-intercept form, simplifying all
fractions.
6x – 15y = 135

Answers

Answer:

Step-by-step explanation:

Slope-intercept form means the equation of a line should be in this form:

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

So we re-write our equation into this form like this:

[tex]6x-15y=135\\-15y=-6x+135\\y=\frac{-6x+135}{-15} \\\\y=\frac{-6x}{-15}+\frac{135}{-15} \\\\y=\frac{2}{5}x-9 \\[/tex]

Answer:

x=3.333 or 10/3

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    3*x-(2*(-6*x+18)+14)=0

Pull out like factors :

  -6x + 18  =   -6 • (x - 3)

to make 3x -  (-12 • (x - 3) +  14)  = 0

Pull out like factors :

15x - 50  =   5 • (3x - 10)  to get

5 • (3x - 10)  = 0

Solve  :    3x-10 = 0

Add  10  to both sides of the equation :

                     3x = 10

Divide both sides of the equation by 3:

                    x = 10/3 = 3.333

Answer:

f

Step-by-step explanation:

substitue the y

3x=2(-6x+18)+14

distrubute

3x=-12x+36+14

combine like terms

3x=-12x+50

add -12x on both sides

15x=50

divide 15 on both sides

x=50/15

simplify

x=10/3

Find three consecutive even integers such that the sum of the second and third is 3 times the first integer.

Answers

Answer:

[tex]6[/tex], [tex]8[/tex] and [tex]10[/tex]

Step-by-step explanation:

Let [tex]x =[/tex] smallest consecutive even integer.

Since the second and third consecutive even integers can be expressed by our smallest even consecutive integer, we can express them as:

Second consecutive even integer = [tex]x+2[/tex]

Third consecutive even integer = [tex]x+4[/tex]

From "the sum of the second and third is 3 times the first integer", we can write:

[tex]x+2+x+4 = 3x[/tex]

[tex]2x+6 = 3x[/tex] (collect like-terms)

[tex]x=6[/tex]

∴ The first consecutive even integer is 6

Now, we can use substitution to find the values of the second and third consecutive even integers:

Second consecutive integer = [tex]x+2[/tex]

[tex]=6+2[/tex]

[tex]=8[/tex]

Third consecutive integer = [tex]x+4[/tex]

[tex]=6+4[/tex]

[tex]=10[/tex]

∴ The three consecutive even integers are [tex]6[/tex], [tex]8[/tex] and [tex]10[/tex].

Tanya is at a fair and has $30 to spend on x number of rides and y number of games. Each ride is $2 and each game is $3. The equation 2x+3y=30 represents this scenario. If Tanya does not play any games, how many rides can she go on?

Answers

Answer:

15 rides

Step-by-step explanation:

From the above Question we know that if Tanya goes on a ride, the Algebraic expression = 2x

Where x = number of rides

If Tanya does not play any games, how many rides can she go on?

Note that: Tanya has $30 to spend

This question is solved:

2x = $30

x = $30/2

x = 15 rides

Hence, if Tanya does not play any games she can go on 15 rides

Minnie is making tea. She knows that her tea tastes best if she lets her tea bag sit in the hot water for exactly fifteen minutes. However, depending how hot the water is, she may have to leave her tea bag in the water for 2 minutes more or less than usual. Write and solve an absolute value equation to describe this situation

Answers

Answer:

|x - 2| = 15 ; |x + 2| = 15

Step-by-step explanation:

Given that:

Wait time = 15 minutes

Variation in wait time depending on level of hotness = 2 minutes

X ± 2 = 15

x + 2 = 15 or x - 2 = 15

x = 15 - 2 = 13 or x = 15 + 2 = 17

Hence, to express the above as an absolute value equation :

|x - variation| = mean time

|x - 2| = 15 ; |x + 2| = 15

A plumber charges a flat fee of $50 plus an additional $20 per hour.

a) Write and equation in slope-intercept form to represent the total cost the plumber will charge

b) How much will it cost for the plumber to work for 4 hours

c) how many hours must the plumber work to obtain $180?

Answers

Answer:

a) cost = 50 + 20x, where x is the number of hours worked for.

plot cost on the y-axis and hours on the x-axis.

b) cost = 50 + 20 x 4 = $130

c) 180 = 50 + 20x

   130 = 20x

   6.5 = x

   additional charges increment every hour, so the plumber must work for 7 hours before they obtain $180.

Maddie bought 3 2/3 yards of satin ribbon at the craft store. She wanted to make hair bows for the cheer squad. Each bow requires 2/3 of a yard of ribbon. How many complete bows can she make?

Answers

Answer:

4

Step-by-step explanation:

Given that:

Total yards of satin bought by Maddie = [tex]3\frac{2}{3}[/tex] yards

Number of yards required make one ribbon = [tex]\frac{2}{3}[/tex] yards

To find:

Number of complete bows that can be made ?

Solution:

First of all, let us learn about converting the mixed fraction to fractional form.

Formula:

[tex]a\dfrac{b}{c} = \dfrac{a\times c+b}{c}[/tex]

Therefore, total yards of satin bought by Maddie can be written in fractional form as:

[tex]3\dfrac{2}{3} = \dfrac{3\times 3+2}{3} = \dfrac{11}{3}[/tex]

One hair bow requires [tex]\frac{2}{3}[/tex] yards of ribbon.

Number of hair bows that can be made, can be found by dividing the total ribbon length by ribbon required for making one hair bow.

Answer is:

[tex]\dfrac{\frac{11}{3}}{\frac{2}{3}}\\\Rightarrow \dfrac{11\times 3}{2\times 3}\\\approx 4[/tex]

4 hair bows can be made.

  y = 14x + 10

Step-by-step explanation:

We are given two points, (x, y) = {(5, 80), (3, 52)}. The 2-point form of the equation for a line can be used to find the equation.

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

  y = (52 -80)/(3 -5)(x -5) +80 . . . . . fill in the given values

  y = (-28/-2)(x -5) +80 . . . . . simplify a bit

  y = 14x -70 +80 . . . . . eliminate parentheses; next, collect terms

  y = 14x +10

A juggler tosses a ball into the air. The balls height, h, and the t seconds can be represented by the equation h(t)=16t^2+40t+4. Suppose the juggler missed and the ball hit the ground. Find the maximum height of the ball and the time it took the ball to reach the ground. Round all answers to the nearest hundredth

Answers

Answer:

h= -20

t = -0.104 and -2.39s

Step-by-step explanation:

A juggler tosses a ball into the air. The balls height, h, and the t seconds can be represented by the equation h(t)=16t^2+40t+4. Suppose the juggler missed and the ball hit the ground. Find the maximum height of the ball and the time it took the ball to reach the ground. Round all answers to the nearest hundredth

The velocity of the body at its maximum height is zero

V= dh/dt

dh/dt = 32t + 40

0 = 32t+40

-32t = 40

t = 40/-32

t = -1.25s

Substitute t = -1.25 into the expression

h(t)=16t^2+40t+4.

h(-1.25)=16(-1.25)^2+40(-1.25)t+4.

h = 16(1.5625)-50+5

h = 25-45

h =-20

Hence the maximums height is -20m

The ball will reach the ground at h = 0

Substitute

h(t)=16t^2+40t+4.

0 = 16t^2+40t+4

Divide through by 4

0 = 4t²+10t+1

Factorize

-10±√10²-4(4)/2(4)

t = -10±√100-16/8

t = -10±√84/8

t =-10+9.17/8

t = -0.83/8 and -19.17/8

t = -0.104 and -2.39s
