Simplify the expression.
2/3y+1/6y+y

Answers

Answer:

I'm not sure, but I am thinking it is 1 5/6y

Step-by-step explanation:

The simplified form of the given expression is [tex]\frac{11y}{6}[/tex] OR [tex]1\frac{5}{6}y[/tex]

From the question,

We are to simplify the expression 2/3y+1/6y+y

First, we will write the given expression properly

The expression can be written as

[tex]\frac{2}{3} y+\frac{1}{6} y+ y[/tex]

The expression can be simplified as follows

[tex]\frac{2}{3} y+\frac{1}{6} y+ y[/tex]

This becomes

[tex]\frac{2 \times 2y + 1 \times 1y + 6 \times y}{6}[/tex]

Then, we get

[tex]\frac{4y+1y+6y}{6}[/tex]

[tex]\frac{11y}{6}[/tex]

OR

[tex]1\frac{5}{6}y[/tex]

Hence, the simplified expression is [tex]\frac{11y}{6}[/tex] OR [tex]1\frac{5}{6}y[/tex]

The Slope is -5/2

Y-intercept is -25

The equation is y=(-5/2)x-25

Step-by-step explanation:

Choose a first point and a second point

Remember points are (x,y)

Use (y₂ - y₁)/(x₂ - x₁)

y-intercept: The initial value of a linear relationship, the place that a linear equation crosses the y axis, represented by the letter b, the point (0,b).

Linear Relationship -the equation that represents a straight line often represented by y=mx+b where m is the slope and b is the y-intercept.

What is Range of Function?

The range of the function is the range of all the y values, from least to maximum. Substitute all possible values of x into the provided expression of y to see whether it is positive, negative, or equal to other values.

We have a graph open upward.

Now, we can see from the graph that the function's maximum y value is -3 and that the graph keeps going up.

So, all real values greater than or equal to -3 are included in the range.

Thus, the range contain all the real numbers greater than or equal to –3

pls help me i dont need the work shown i just need the answer

Answers

Answer:

3. C.) $15,500 4. C.) 45 mi

Step-by-step explanation:

I know you said you don't need work but I want to make sure you're still learning. So for the first one you just recognize the pattern in the chart. The numbers are going up 2 for every number, so if 36 is equivalent to 11, then 38 would be 12, 40 would be 13 and so on. Eventually, we get to 44 being equivalent to 15, we don't wanna go all the way up to 46 so we stop at 15 and only add half to our fifteen, so we end off with 15.5. Then we multiply that by 1000 and get 15,500. Then we just add our units, which in this case is dollars to get $15,500. For the second problem we just divide 35 mi by 7 hours and we get 5, we now know that Elise is traveling at 5 miles per hour. Then we multiply 5 by 9 to get 45. Don't forget to add your units though! This time our unit is miles, so we get our final answer of 45 mi.

For you to get to figure y you just divide all the triangle sides on X by 3 so: 9÷3=3, 9÷3=3, 12÷3=4 and the answers to those divisions are the sides on triangle Y.

To get from figure Y back to X again, you do the opposite and MULTIPLY your sides by 3: 3·3=9, 3·3=9, 3·4=12 SO THE ANSWER IS: 3

For 10:

To get to figure Y you add 6 to your sides and then to get from figure Y to X you SUBTRACT 6

Answers

Answer:

33

Step-by-step explanation:

Answer:

33

Step-by-step explanation:

A ratio can be used to answer this question.  The equation below shows that you travel 330 feet in 10 seconds on the left side and you are trying to determine how many feet you travel in 1 second on the right side.

330 feet               X feet

_______       =   _______

10 seconds           1 second

X is the answer you are looking for.  To solve for X, you use cross multiplication.  Therefore, you have this equation:

10 times X = 330 times 1 or simplified to 10X = 330

To solve for X, you divide both sides of the equation by the number 10.

The left side of the equation becomes 1X or X and the right side becomes 33.

So X (the answer) is 33 feet.
