Which rates are unit rates?

1 answer:

5 0

Unit rate is a rate that has a denominator of 1. In order to get the unit rate given the denominator is not 1, then unit rate is acquired by getting the equal ration with denominator 1. On the question, Letter A. 4 yd/carry, Letter B. 35 mi/1gal and Letter D. 3 cups per batch are unit rates.

What value of x <br> in the solution set of 2(3x – 1) ≥ 4x – 6?

Brrunno [24]

First, you must distribute 2(3x-1).
To do that, you will multiply 2•3x, and 2•-1 because you are taking the number outside of the parentheses and multiplying (distributing) it to all the numbers inside

After distributing, the left side of your inequality will be 6x-2

Now you have
$6x - 2 \geqslant 4x - 6$

To find the value of x, you must subtract an x value from both sides of the equation, as well as a constant from each side.

so you have
$6x - 2 \geqslant 4x - 6 \\ - 6x \geqslant + 6$
And that will make the equation
$- 4 \geqslant - 2x$
Now, divide the variable side, ***BUT, because you are dividing by a negative number in an inequality, the inequality will switch sides.

Then, the value of x is greater than or equal to 2

The negative outside a function with no other transformations reflects the graph of the function over which line?

andrezito [222]

The negative outside a function with no other transformations reflects the graph of the function over the x-axis.

<h3>How to Interpret Graph Transformations?</h3>

When we talk about reflection in transformation, we know that ;

Reflection over x-axis is defined as a reflection or flip over the x-axis where the x-axis is the line of reflection used.

The formula for this is: (x, y) → (x, −y) . To reflect an equation over the x-axis, simply multiply the output variable by negative one: y = f(x) → y = −f(x)

Thus, we can conclude that the negative outside a function with no other transformations reflects the graph of the function over the x-axis.

A woman made $45,000 during the first year of her new job at city hall. Each year she received a 10% raise. Find her total earni

kati45 [8]

Equation: 45000(1+.1)^6

Answer: 79720.25

Explanation:

This is a prime example of a Compound Interest Formula based question. Due to the fact the question states that the woman is getting a raise every year, we add one rather than subtracting one. Next we convert the 10% into a decimal form into 0.1 and from there since the time is all the same we wouldn’t need to divide anything out so we raise the equation to the sixth power and our final answer is $79720.25

3. Decide whether each equation is true or false, and explain how you know.

BARSIC [14]

Answer:

a.false

b.true

c.false

d.I really can't get about it.

e.false

Step-by-step explanation:

So,here;

a.9.9.3=35 is given

or,243=35 (which is false)

b.7+7+7=3+3+3+3+3+3+3

or,21=21 (which is true)

c.2/3/2=2/3

or,2*2/3=2/3

or,4/3=2/3(which is false)

e.6+6+6=63

or,18=63 (which is false)
