Answer:

Step-by-step explanation:

y=3/4x-2

Answer:

y=3/4x-2

Step-by-step explanation:

slope-intercept formual: y = mx + b

m (the slope) = (y2-y1) / (x2-x1) so right here we insert (4-1) / (8-4) = 3/4  

b =w here the line touches the y-asix = -2

now insert those numbers in the formual: y = (3/4)x + (-2)

final answer: y=3/4x-2

Answer:

y = 1/6x + 2

Answer:

x = 17

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles and equate to 180, that is

6x - 15 + 4x - 7 + 2x - 2 = 180, that is

12x - 24 = 180 ( add 24 to both sides )

12x = 204 ( divide both sides by 12 )

x = 17

Answer:

(-3a+4b) (2x+2y)

Step-by-step explanation:

Expand.

4(x+y)(3a-b)+6(x+y)(2b-3a) = 4(3ax+3ay-bx-by) + 6(2bx+2by-3ax-3ay)

4(3ax+3ay-bx-by) + 6(2bx+2by-3ax-3ay)  = 12ax+12ay-4bx-4by+12bx+12by-18ax-18ay

Calculate like terms.

12ax+12ay-4bx-4by+12bx+12by-18ax-18ay = -6ax-6ay+8bx+8by

Factorise.

-6ax-6ay+8bx+8by = -3a(2x+2y) + 4b(2x+2y)

Factorise further.

-3a(2x+2y)+4b(2x+2y) = (-3a+4b) (2x+2y)

Step-by-step explanation:

Answer: y > -4 + x

Step-by-step explanation: graph the inequality by finding the boundary line

Answer:

y > -4 + x

***(see graph below)****

Step-by-step explanation:

Graph

x − y < 4

Solve for y

Subtract x from both sides of the inequality.

−y < 4 − x

Multiply each term in −y < 4 − x by −1

Multiply each term in −y < 4 − x by −1. When multiplying or dividing both sides of an

  inequality by a negative value, f lip the direction of the inequality sign.

  (−y) ⋅ −1 > 4 ⋅ −1 + (−x) ⋅ −1

     Multiply (−y) ⋅ −1.

     Multiply −1 by −1.

     1y > 4 ⋅ −1 + (−x) ⋅ −1

     Multiply y by 1.

     y > 4 ⋅ −1 + (−x) ⋅ −1

Simplify each term.

     Multiply 4 by −1.

      y > −4 + (−x) ⋅ −1

     Multiply (−x) ⋅ −1.

y > −4 + x

   Find the slope and the y-intercept for the boundary line.

Rewrite in s lope-intercept form.

The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

y = mx + b

Reorder −4 and x. y > x − 4

Use the slope-intercept form to find the slope and y-intercept.

Find the values of m and b using the form y = mx + b. m = 1

b = −4

The slope of the line is the value of m, and the y-intercept is the value of b.

Slope: 1

intercept: (0, −4)

Graph a dashed line, then shade the area above the boundary line since y is greater than −4 + x. y > −4 + x

Shirt: $2.25. and Pants: $1.50

Step-by-step explanation:

Set up equations with shirts as s and pants as p.

Subtract them as there are two variables and two equations:

To find s:

Answer:

(y - 25) = - 0.25(x - 20)

Step-by-step explanation:

Given that :

Height of candle after burning for 20 minutes = 25 cm

Height after burning for 1 hr (60 minutes) = 10 cm

Height (y) in cm of candle x minutes after being lit:

Using the equation :

(y - y1) = m(x - x1)

m = (change in y / change in x)

Change in height within 60 minutes :

Height at 20 minutes = 25cm

Height after an hour = 10

Change in height per hour = (25 - 10) = 15cm

Hence, m = change in height per minute

15cm / 60 = 0.25cm ( - 0.25) (decrease in height)

y1 = 25 ; x1 = 20

(y - y1) = m(x - x1)

(y - 25) = - 0.25(x - 20)

Answer:

The value of each book is 7  

The value of each music note is 6

Step-by-step explanation:

The first equation includes the sum of 3 books and 2 music notes, so 3b + 2m = 33.

The second equation includes the sum of 1 book and 3 music notes, so b + 3m = 25.

This is the system that represents the puzzle:

3b + 2m = 33

b + 3m = 25  

Solve the second equation for b, and then substitute the equivalent expression for b in the first equation.  The value of each music note is 6.

Then, Substitute the value of m into one of the original equations to find the value of b . The value of each book is 7.

Answer: it just depends on how much each lawn pays him

Complete question :

On average, light emitted from the Sun takes 8 minutes 19 seconds to reach Earth. Using your approximated speed of light from part (b), as well as the equation distance = rate x time, calculate the approximate distance from the Earth to the Sun in meters. Write your answer in standard form and in scientific notation.

Answer:

1.497 * 10^8km

149700000 km

Step-by-step explanation:

Given that:

Time taken = 8 minutes 19 seconds

Speed of light = 3 * 10^8 m/s

Distance from earth to sun :

Speed * time

(3 * 10^8) * ((8 * 60) + 19)

(3 * 10^8) * 499

= 1497 * 10^8 m or 1497 * 10^5 km = 1.497 * 10^8km

= 149700000000 m

= 149700000 km

= 1497

Answer:

Cameron need to mow 4 lawns.

Step-by-step explanation:

Cameron needs 11$ for some new toys.

But he charges 3$ to mow a lawn.

So, he needs to mow 11/3= 3.66... lawns

The number of lawns can not be decimal. So, let's round to next whole number as 4.

B) 60-59 = 1

A) 61-59 = 2

Hope this helps! :)

Tell me if I am correct! :)

Step-by-step explanation:

2n is the answer because you combined the two variables then you do 20n plus 20n minus. 10 equals 50 then subtract 10 from 50 and get forty the divide that by 20 which equals 2

Answer: 3mn^2.

Step-by-step explanation: GCF stands for Greatest Common Factor, as you know. The greatest common factor of 75 and 27 is 3. For the rest, we just use the smallest values. Thus, the answer is 3mn^2.

Answer:

18² + 24² = x²

900 = x²

x = 30

18 + 24 = 42

42 - 30 = 12

Its shorter for 12 miles

Answer:

12 miles less

Step-by-step explanation:

18+24=42

If you walk in a L shape you walk 42 miles

If you walk diagonally:

ABC Right triangle

We have A and B (18 and 24)

Using the pythagorum theorem

a^2+b^2=c^2

18^2+24^2=C^2

324+576=C^2

900=C^2

Square root of 900=C

30=C

You would walk 30 miles

42-30=12

By walking diagonally, you would walk 12 miles less than going all the way around.

Answer:

10(g*h)

Step-by-step explanation:

the * is supposed to mean times/multiply

since it is an expression you do not put y= or f(x)= or anything like that

Answer:

10(g*h)

Step-by-step explanation:

"Product" means multiply so you would want to multiply g and h together. You put it in parenthesis because you want to multiply the solution you get from multiplying g and h by 10. To show this, you can simply just put the 10 in front of  the parenthesis as that implies multiplication.
