identify the slope of the line for the equation 1/6 x + 1/4

Answers

Answer:

y = 1/6x - 8/3

Step-by-step explanation:

The equation of a line in slope-intercept form is.

y = mx + b

where m represents the slope and b, the y-intercept.

Rearrange y + 2 = 1/6 (x - 4)  into this form

distribute bracket and simplify.

y + 2 = 1/6x - 2/3

⇒ y = 1/6x - 2/3 - 2

⇒ y = 1/6x - 8/3 ← in slope-intercept form

Tavon has a gist card for $145 that losses $3.50 for each 30-day period is not used. He has another gift card for $125 that losses $3 for each 30-day period it is not used. A. Write and solve an equation for the number of 30-day periods until the value of the gift cards will be equal. B. What will the value of each card be when they have equal value?

Answers

Step-by-step explanation:

A. For Tavon's gift card the equation is

let y be the total amount

let x be the number of 30 day period

y=145-3.5x------1

for Tavon's second gift card the equation is

let y be the total amount

let x be the number of 30 day period

y=125-3x-------------2

B. equating 1 and 2 we have

145-3.5x=125-3x

solve for x we have

145-125=-3x+3.5x

20=0.5x

divide both sides by x we have

x=20/0.5

x= 40

put x=40 in

y=145-3.5*40------1

y=145-140

y=$5

put x=40 in

y=125-3*40------1

y=125-120

y=$5

-66 = -9n + 16n + 4
Solve these step by step pls

Answers

Answer:

n= -10

Step-by-step explanation:

-66=7n+4

-7n=4+66

-7n=70

n=70/-7

n= -10

Answer:

n = -10

Step-by-step explanation:

-66 = -9n + 16n + 4

1. I started by subtracting 4 on both sides of the equation this gives you -70 = -9n + 16n

2. I then combined the like terms 16n and -9n on the right side of the equation. We do this by subtracting 9n from 16n. Which gives you -70 = 7n

3. We then divide both sides by 7 in order to get -10 = n

This gives you your final answer of n = -10

Find the intersection point for the following linear functions.

f(x) = 2x + 3
g(x) = -4x − 27

A. (5,-7)
B. (5,13)
C. (-5,-10)
D. (-5,-7)

Answers

Answer:

D) (-5, - 7)

Step-by-step explanation:

Because both lines intersect, they must share a point (have same x and y coordinates).

[tex]2x + 3 = - 4x - 27[/tex]

[tex]2x = - 4x - 30[/tex]

[tex]6x = - 30[/tex]

[tex]x = - 5[/tex]

Substite x for - 5 in any of the equations to find the y coordinate.

[tex]y = 2( - 5) + 3 [/tex]

[tex]y = - 10 + 3[/tex]

[tex]y = - 7[/tex]

The x coordinate for the intersection point is - 5 and the y coordinate is - 7. The intersection point is (-5, - 7)

My question is, on Sunday, 77,098 fans attended a New York Jets game. The same day, 3,397 more fans attended a New York Giants game than attended the Jets game. Altogether, how many fans attended the games? Round each number to the nearest thousand to find an estimate of how many fans attended the games.

Answers

Answer:

Total number of fan = 80,495

Step-by-step explanation:

Given:

Number of fans attended = 77,098

Additional number of fans attended = 3,397

Find:

Total number of fan

Computation:

Total number of fan = Number of fans attended + Additional number of fans attended

Total number of fan = 77,098 + 3,397

Total number of fan = 80,495

Step-by-step explanation:

A hexagon has six sides, and we can use the formula degrees = (# of sides – 2) * 180. Then degrees = (6 – 2) * 180 = 720 degrees. Each angle is 720/6 = 120 degrees.

Step-by-step explanation:

Manny and Zack are hosting events that are catered by the same company. Manny plans to have 66 adults and 27 children attend, so the total projected cost of his meals is $3,651. Zack has 77 adults and 43 children on his guest list, so he will pay the caterer $4,409. How much does the caterer charge for each meal?

Answers

Answer:

The caterer charged $50 for an adult's meal and $13 for a child's meal

Step-by-step explanation:

Let the cost of an adult meal be $x

and the cost of a child meal be $y

From the question,

Manny plans to have 66 adults and 27 children and the total cost of his meals is $3,651.

We can write that

66x + 27y = 3651 ...... (1)

Also, from the question,

Zack has 77 adults and 43 children and the total cost he will pay the caterer is $4,409.

We can also write that

77x + 43y = 4409 ...... (2)

Multiply equation (1) by 7, so that we get

462x + 189y = 25557 ...... (3)

Multiply equation (2) by 6, so that

462x + 258y = 26454 ...... (4)

Now, subtract equation (3) from equation (4), so that

69y = 897

∴ y = 897/69

y = 13

Put the value of y into equation (1) to get x

66x + 27y = 3651

∴ 66x + 27(13) = 3651

66x + 351 = 3651

66x = 3651 - 351

66x = 3300

x = 3300/66

x = 50

Therefore,

The cost of an adult's meal is $50

and the cost of a child's meal is $13

Hence, the caterer charged $50 for an adult's meal and $13 for a child's meal.

if 1/2 gallon of paint covers 1/12 of a wall,then how many quarts of paint are needed for the entire wall

Answers

Answer: 4

Step-by-step explanation: there is 4 quarts in a gallon so 1/2 gallon is 2 quarts. 2x2=4

Answer:

6 gallons which is 24 quarts

Step-by-step explanation:

because while covering 2/12ths of a wall you used a whole gallon of paint so if 1 gallon covers 2/12ths of a wall you have 10/12ths left and s you already used 1 so it  would leave you with 5 gallons and 10 divided by 2 is 5 which would give you your answer  6 gallons and there are 4 quarts in a gallon so you would multiply 6 *4 = 24

Step-by-step explanation:

n - 13 x -2 = -44

distribute:

(n x -2) - (13 x -2) = -44

-2n - (-26) = -44

two negatives in front of a number makes it a positive number

so rewrite -2n + 26 = -44

-2n = -44 -26

-2n = -70

n = [tex]\frac{-70}{-2}[/tex]

n = 35

Find the exact rotation in revolutions per minute with the angular speed below:

Answers

Answer:

The exact rotation in revolutions per minute is 1.125 revolutions per minute

[tex]\omega = 1.125 \ \dfrac{Revolution}{minute}[/tex]

Step-by-step explanation:

The given angular velocity is expressed as follows;

[tex]\omega = 135 \cdot \pi \ \dfrac{rad}{h}[/tex]

Therefore, we have;

[tex]\omega = \dfrac{135 }{60} \cdot \pi \ \dfrac{rad}{minute} = \dfrac{9}{4} \cdot \pi \ \dfrac{rad}{minute} = 2.25 \cdot \pi \ \dfrac{rad}{minute}[/tex]

One (1) revolution = 2·π radian

Therefore;

π radian =  1/2 revolution

2.25·π radian = 2.25 × 1/2 revolution = 1.125 revolution

Which gives;

[tex]2.25 \cdot \pi \cdot \dfrac{rad}{minute} = 1.125 \ \dfrac{Revolution}{minute}[/tex]

The exact rotations in revolutions per minute is 1.125 revolutions per minute.
