Express this rate as a unit rate: $50 for 4 days of work. Note: You must label your unit rate.

Answers

Answer:

12.50 dollars per day

Step-by-step explanation:

This is a fraction equal to

50 dollars ÷ 4 days

We want a unit rate where

1 is in the denominator,

so we divide top and bottom by 4

50 dollars ÷ 4

4 days ÷ 4

=  

12.5 dollars

1 day

=  

12.5 dollars

day

= 12.5 dollars per day

Given: f(x) = 1/x+5 and g(x) = x - 2.
What are the restrictiorts of the domain of f(g(x))?
0 x4 -5
O X-3
OX= 2
There are no restrictions.

Answers

Answer:

The restriction of the domain of f(g(x)) is that x cannot be 3.

Step-by-step explanation:

The first step to solve this question is finding the function, replacing the values. So

[tex]f(x) = \frac{1}{x+5}[/tex]

[tex]g(x) = x - 2[/tex]

[tex]f(g(x)) = f(x - 2) = \frac{1}{x - 2 + 5} = \frac{1}{x - 3}[/tex]

The function is a fraction, which means that the restriction is that the denominator cannot be zero. So

[tex]x - 3 \neq 0[/tex]

[tex]x \neq 3[/tex]

The restriction of the domain of f(g(x)) is that x cannot be 3.

-x+y=-2 in slope intercept form​

Answers

Answer:

y = x - 2

Step-by-step explanation:

Slope intercept form is: y = mx + b, where m is the slope and b is the y- intercept. In this question, we are given everything, and all we need to do is rearrange the terms.

-x + y = -2

Add x to both sides

y = x - 2

In this equation, the slope is 1 and the y intercept is -2.

Answer:

Step-by-step explanation:

Y = mx + b

Y = x -2 after adding x to both sides of equation

m = 1 and b = -2

2a - 3b = -11
a + 3b = 8

Answers

Answer:

b = 3 and a = -1

Step-by-step explanation:

You have your given equation:

2a - 3b = -11

a + 3b = 8

You need to find what a and b is.

To find b:

2a - 3b = -11

-2a - 6b = -16

I multiplied a + 3b = 8 by -2. When you multiply a number you have to multiply all of them. You have to choose a number that would cancel out all of a.

So now your equation would look like this when you solve for b:

2a - 3b = -11

-2a - 6b = -16

-------------------

a - 9 = -27 then you divide -9 to -27 which is 3 so b = 3.

To find a:

2a - 3b = -11

a + 3b = 8

I multiplied a + 3b = 8 by -1 and 2a - 3b = -11 by -1 as well.

Your equation will look like this when you solve for a:

-2a + 3b = 11

-1a - 3b = -8

------------------

-3a = 3 then divide -3 to 3 which is -1 so a = -1.

Check to see if you have the correct answer by plugging in the number you got for a and b into the equation and solve.

1. 2(-1) -3(3) = -11

 -2 - 9 = -11

2. -1 + 3(3) = 8

   -1 + 9 = 8

what is the sign of f on the interval -5

Answers

Answer:

f(x) = x3 - 3x + 1

f'(x) = 3x2 - 3 = 3(x2 - 1) = 3(x+1)(x-1)

Find the critical numbers:  set f'(x) = 0

                                    3(x+1)(x-1) = 0     x = 1, -1

Check the sign of f'(x) on either side of each critical number.  If f'(x) is positive on an interval, then f is increasing on the interval.  If f'(x) is negative on an interval, then f is decreasing on the interval.

11100020
11 1303170
11 1000 210

Answers

Answer:

Answer is in attached image.

Step-by-step explanation:

Given the expressions, for which we have to find the estimates as per the expressions on the left.

The given expressions are:

1) 35 [tex]\times[/tex] 23

2) 132 [tex]\div[/tex] 168

3) 17.3 [tex]\times[/tex] 18.4

4) 999 [tex]\div[/tex] 208

5) 998 [tex]\times[/tex] 211

Here, we need to find the rounded off numbers.

35 can be rounded to 40 and 23 to 20.

Therefore, equivalent to 35 [tex]\times[/tex] 23 is 40 [tex]\times[/tex] 20

132 can be rounded to 130 and 168 to 170.

Therefore, equivalent to 132 [tex]\div[/tex] 168 is 130 [tex]\div[/tex] 170.

17.3 can be rounded to 17.0 and 18.4 to 18.0.

Therefore, equivalent to 17.3 [tex]\times[/tex] 18.4 is 17.0 [tex]\times[/tex] 18.0.

999 can be rounded to 1000 and 208 to 210.

Therefore, equivalent to 999 [tex]\div[/tex] 208 is 1000 [tex]\div[/tex] 210.

998 can be rounded to 1000 and 211 to 210.

Therefore, equivalent to 998 [tex]\times[/tex] 211 is 1000 [tex]\times[/tex] 210.

The solution can be found in the attached image as well.

express 28x-35y=-7,inthe form ax+by+c=0and find the value of a,b,&c​

Answers

Answer:

a = 28, b = -35 and c =7

Step-by-step explanation:

Given expression is :

28x-35y=-7

We need to express it in the form of ax+by+c=0 and then find the value of a,b and .

Adding 7 to both sides.

28x-35y+7=-7+7

28x-35y+7=0

or

28x+(-35y) +7=0

It is in the form of ax+by+c=0.

On comparing,

a = 28, b = -35 and c =7

Hello there!

Explanation:
↓↓↓↓↓↓↓↓
First you had to multiply without the decimal points, and then you put the decimal point it should be the correct answer.

5.6 it has one decimal place.
7.3 it has one decimal place.
Therefore, the answer should be the two decimal places.

Answer⇒⇒⇒⇒⇒40.88
Hope this helps!
Thank you for posting your question at here on Brainly.
Have a great day!
Well, we have to answer 5.6 by 7.3.
First of all, let’s answer this question just like that without converting anything:
5.6 * 7.3 = 40.88
So, we have our answer which is 40.88 but the question also tells us to answer this question using whole numbers instead of decimals so, what we are going to do is that we will multiply both 5.6 and 7.3 by ten so that we change them to 56 and 73.
Once we finish multiplying 5.6 and 7.3 together, we will take our answer and divide it by 100 (moving two spaces to the left of our answer) because we multiplied our two numbers by ten which is 2 decimal places do, when we get our answer, we will move back those two decimal places.
= 56 * 73
= 4088
= 4088 / 100
= 40.88.

So, in conclusion, we came up with the same exact answer!
Really glad that I could help and have a fantastic day!
Also, can you please mark my answer as the brainliest answer?
