What is the slope in the equation? y + 2 = 5(x - 1)​

Answers

Answer 1

Answer:

m=5

Step-by-step explanation:

Answer 2

Answer:

5

Step-by-step explanation:

Let's write the equation in the slope-intercept form by solving for y.

y + 2 = 5(x - 1)

y = 5x - 5 - 2

y = 5x - 7

Answer: The slope is 5

through: (1, 2), slope = 2

Answers

Answer:

y=2x+2

Step-by-step explanation:

Answer: y = 2x

Step-by-step explanation:

y=mx+b

m is the slope. so if the slope is 2 we can fill in 2 for m.

y = 2x + b

now we are going to plug in the point they gave us (1, 2) to find b.

1 is the x coordinate of the point and 2 is the y coordinate. so we put 1 in for x and 2 in for y.

2 = 2(1) + b

2 = 2 + b

b = 0

so our equation is y = 2x + 0, or y = 2x

why does math have to be so hard

Answers

I felt this, I’m currently failing even tho I’m trying but that could also be because my teacher doesn’t like me

Answer:

Math seems difficult because it takes time and energy. Many people don't experience sufficient time to "get" math lessons, and they fall behind as the teacher moves on. Many move on to study more complex concepts with a shaky foundation. We often end up with a weak structure that is doomed to collapse at some point.

Math is hard because it is a non-intuitive, non-natural activity. Math don't happen by chance only, it only happens with deliberate, focused work. For this you expend a lot of energy and cause a lot of mental strain, you put yourself on an uncomfortable condition for hours, days, sometimes weeks to solve a problem.

But some people love math, like me, because they study math more than others. If you study more and learn more about math, then you’ll start to feel more comfortable because you’ll be ahead of the class when your teacher teaches you something.

The most important thing is to keep trying and never give up.

Hope this helps! :)

A bowling alley charges $2.50 per game plus $4 to rent shoes. A second bowling alley charges $4 per game plus $1 to rent shoes. How many games would a
person have to play for the two bowling alleys to cost the same amount?

Answers

Answer:

The person would have to play 2 games for the two bowling alleys to cost the same amount

Step-by-step explanation:

Assume that the number of games that makes the two costs equal is x

∵ A bowling alley charges $2.50 per game plus $4 to rent shoes

∵ The number of games is x

∴ The cost = 2.50x + 4

∵ A second bowling alley charges $4 per game plus $1 to rent shoes

∵ The number of games is x

∴ The cost = 4x + 1

∵ They have the same cost

→ Equate the 2 expressions above

∴ 4x + 1 = 2.50x + 4

→ Subtract 2.50x from both sides

∵ 4x - 2.50x + 1 = 2.50x - 2.50x + 4

∴ 1.50x + 1 = 4

→ Subtract 1 from both sides

∵ 1.50x + 1 - 1 = 4 - 1

∴ 1.50x = 3

→ Divide both sides by 1.50

∴ x = 2

∴ The person would have to play 2 games for the two bowling alleys to

   cost the same amount

B. 8 x 1/5
C. 2 x 4/5
D. 4 x 2/5
C. 2 x 6/5

Answers

Answer:

B, C, and D

Step-by-step explanation:

A) 5 x 1/8 is 5/1 times 1/8 which is 5/8 (Incorrect)

B) 8 x 1/5 is 8/1 times 1/5 (multiply straight across and you get 8/5 (Correct)

C) 2 x 4/5 (again, it's 2/1 just multiply straight across and you are basically only multiplying the two numerators each time. Because 1 times 5 will always be 5) (Correct)

D) Correct because 4 times 2 is 8 which is over 5, hence, 8/5 (Correct)

E) 2 times 6 is 12 over 5 which is 12/5, not 8/5. (Incorrect)
