How do you write 5y<3 without exponents?

Answers

Answer:

When an exponent is 1, the base remains the same. a 1 = a . When an exponent is 0, the result of the exponentiation of any base will always be 1, although some debate surrounds 0 0 being 1 or undefined. For many applications, defining 0 0 as 1 is convenient.. a 0 = 1 . Shown below is an example of an argument for a 0 =1 using one of the previously mentioned exponent laws.

In complete sentences explain why you can sometimes add square roots with different radicands. Give an example where you can add square roots with different radicands and an example where you cannot add square roots with different radicands.

Answers

Answer:

Just as with "regular" numbers, square roots can be added together. But you might not be able to simplify the addition all the way down to one number. Just as "you can't add apples and oranges", so also you cannot combine "unlike" radical terms. In order to be able to combine radical terms together,

those terms have to have the same radical part.

or, 3x- 5 + 2x - 15=180°

or,5x - 20 = 180°

or, 5x = 180°+20

or, x = 200÷ 5

•°•x = 40°

Answer:

X = 40

Step-by-step explanation:

3x + 2x -5 -15 = 180

5x + -20 = 180

then u add 20 on both sides

5x + 0 = 200

ya the 0 is not necessary but I was showing u add 20 on both sides lol

then u divide 5 on both sides to get the x by itself

x = 40

3. The points (15,21) and (25,35) form a proportional relationship.
a) Find the slope of the line through the points.
b) Which graph represents this relationship?

Answers

Answer:the letter is c because it the only one that is lined up and I got it right trust me

Step-by-step explanation:

The slope of the line passing through (15,21) and (25,35) is 7/5.

What is slope?

The slope of a line is a measure of its steepness.

Given that, the points (15,21) and (25,35) form a proportional relationship.

Slope = (y2-y1)/(x2-x1)

= (35-21)/(25-15) = 14/10 = 7/5

The equation of a line passing through these two points are;

y - y1 = [(y2−y1)/(x2−x1)](x - x1)

y - 21 = 7/4(x - 25)

y = 7x/4 - 14

Hence, the slope of the line = 7/5

Two numbers have square roots about 40 apart. What could they be?

Answers

They could be 7 (49) and 9 (81) or 10 (100) and 12 (144)

The two numbers such that their square roots about 40 apart will be 2401 and 81.

What is a number system?

The number system is a way to represent or express numbers.

A decimal number is a very common number that we use frequently.

Any of the multiple sets of symbols and the guidelines for utilizing them to represent numbers are included in the Number System.

Let's consider the number 8² = 64

Now, 64 - x = 40

x = 64 -40 = 24 and it is not a square of any number.

Take, 7² = 49

49 - x = 40

x = 9 it is a square of 3.

Thus, 7² - 3² = 40

So, 49² = 2401 and 9² = 81

Hence "The two numbers such that their square roots about 40 apart will be 2401 and 81".

Please solve 7y - 8 = 6y + 1 AND FAST PLEASE

Answers

In order to solve this problem, we must first p it all variables on one side and all numbers on the other.

7y-8=6y+1

We subtract 6y from both sides to cancel it out on the right and have it on the left.

Y-8=1

Now, we put the numbers on the opposing side.

Y=9

We receive the answer Y=9

To check it, we can plug or input 9 into both equations.

7(9)-8=6(9)+1
63-8=54+1
55=55

Now that we know they are equal, we can conclude that the answer is 9.

Answer:

y=9

Step-by-step explanation:

7y-6y= y

y-8=1

Answers

Answer: i say number 3

Step-by-step explanation:

because i pay attention in math class

The equation y = x has the positive slope.

What is Slope?

Slope of a line is the ratio of the change in y coordinates to the change in the x coordinates of two points given.

Slope can also be defined as the tangent of the angle that the line is making with the positive X axis.

Given three equations which are in the form of slope intercept form of the equation of a line.

Slope intercept form of a line is y = mx + d, where m is the value of the slope and d is the value of the y intercept.

y intercept is the y coordinate of the point on the line where it touches the Y axis. The x coordinate will be 0 there.

Equations given are

y = -x + 0 ⇒ Slope = -1

y = x ⇒ Slope = 1

y = -4 ⇒ Slope = 0

So y = x has the slope equal to 1 which is positive.

Hence the equation y = x has the positive slope.
