Can someone please explain slope in a way that might make sense.

Answers

Answer 1
Okay let’s take the question “Find the slope of the points (4, 1) and (-2, 7)” as an example

The slope of an equation or graph is the rate of change.

In order to find slope, we use the formula m=rise/run or m=y2-y1/x2-x1

“m” is equal to the slope

“rise” or “y2-y1” is the difference (subtraction) of the two y coordinates

“run” or “x2-x1” is the difference (subtraction) of the two x coordinates

Remember, the points we are using for this example are (4, 1) and (-2, 7)

m = y2-y1/x2-x1
m = 7-1/-2-4

1 and 7 are your y coordinates so you plug them in an find the difference (subtraction)

4 and -2 are your x coordinates so you plug them in an find the difference (subtraction)

It doesn’t matter whether you do “m=7-1/-2-4” or “m=1-7/4-(-2)” both will have the same answer

The only thing you can’t do is something like “m=7-1/4-(-2)” or “m=1-7/-2-4”

The bottom can’t be solved in the opposite way of how it was solved on top and vice versa of that makes sense

Also, keep in mind that if you see two negatives as in the “m=1-7/4-(-2)” example, you turn it into an addition symbol

Like this:
“m=1-7/4+2)”

Because two negatives are equal to a positive

m = y2-y1/x2-x1
m = 7-1/-2-4
m = 6/-6
m = 6/-6
m = -1

Remember that a negative divided by a positive is always a negative so it doesn’t matter where you place the negative sign

For example, if your slope was 2/-5, that would be the same as -2/5

And when you divide two negatives, it always equals to a positive

For example -2/-5 would simplify to 2/5

I hope that helped and made sense :)

During the summer, you had an ice cream cone with
your friends almost every day. Your parents bought
a half gallon of ice cream for $4.75. It was on
Sale for 15% off. What was the sale price?

Answers

Answer:

$4.04

Step-by-step explanation:

Since the ice cream is 15% off, that means you will have to subtract 0.15 from 1, since 1 is 100%, and 0.15 is 15%. If you do the math, then you will get 0.85, which translates to 85%. So now that we have found the percentage of the original price that we have to pay, we can do some more advanced calculations. Since we found the 1 - 0.15 = 0.85, we will multiply the original price, which is $4.75, by 0.85. You can do this by hand or by calculator. You will get 4.0375, which is your answer. Since this is about money, you will have to add a $ sign at the beginning, which would be $4.0375. Of course, you can't pay a percentage of a cent, so you would have to round that up to $4.04. In conclusion, the sale price of the half-gallon of ice cream is $4.04.

Tell whether the angles are adjacent or vertical. Then find the value of x.
I finished the angles, but need the value of x.

Answers

Answer : The angles are vertical angles and the value of x is [tex]25^o[/tex]

Step-by-step explanation :

Adjacent angles : It is defined as the two angles that have the common arm and common vertex.

Vertical angles : It is defined as the two lines intersect each other and form angles. The opposite angles are known as vertically opposite angles.

And we know that the vertically opposite angles are equal.

In the given image, the angles are vertical angles and vertically opposite angles are equal.

So,

[tex](4x-25)^o=75^o[/tex]

[tex]4x-25^o=75^o[/tex]

[tex]4x=75^o+25^o[/tex]

[tex]4x=100^o[/tex]

[tex]x=\frac{100^o}{4}[/tex]

[tex]x=25^o[/tex]

Therefore, the angles are vertical angles and the value of x is [tex]25^o[/tex]

Answers

Answer: x= -7

Explanation for answer:

Answer:

x = -7

Step-by-step explanation:

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other.

First, add 2x and subtract 18 from both sides:

5x - x + 18 (-18) (+2x) = 6 - 2x (+2x) - 30 (-18)

5x - x + 2x = 6 - 30 - 18

Next, simplify. Combine like terms:

(5x - x) + 2x = 6 + (-30 - 18)

(4x) + 2x = 6 + (-48)

6x = -42

Next, fully isolate the variable, x, by dividing 6 from both sides:

(6x)/6 = (-42)/6

x = -42/6 = -7

x = -7 is your answer.

Answer:

  24 cm^2

Step-by-step explanation:

The larger rectangle has dimensions in cm of 12 by (4+x). The smaller rectangle has dimensions of (x+2) by x. The area of the larger is 4 times the smaller, so ...

  12(4+x) = 4(x)(x+2)

  3(4+x) = x(x+2) . . . . . . divide by 4

  x^2 +2x -3x -12 = 0 . . . eliminate parentheses, subtract 3(4+x)

  (x -4)(x +3) = 0 . . . . . . . factor

The positive solution is x = 4, so the area of the smaller rectangle is ...

  x(x+2) = 4(4+2) = 24 . . . cm^2

Answers

Answer:

80 pages

Step-by-step explanation:

Let the required length of paper = x

Hence:

80% of x = 64 pages

80/100 × x = 64 pages

80x /100 = 64 pages

Cross Multiply

80x = 100 × 64 pages

x = 6400/80

x = 80 pages

Therefore, the required length of the paper = 80 pages
