Write the sentence as an inequality.
The sum of a number y and 9 is at least -1.
y +9 >= -1
Sum of a number(y) and 9. Is greater than or equal to negative one. Sum means add, so add y, and 9. It has to be atleast negative one, so greater than (0,1,2,3...), or equal to(-1).
Hope this helps, if you have more questions, feel free to ask.
The sum of a number y and 9 is at least -1 as an inequality is y + 9 ≥ 1.
What is an inequality?In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to each other. To solve the inequality, you may multiply or divide each side by the same positive number, add the same amount to each side, take the same amount away from each side, and more. You must flip the inequality sign if you multiply or divide either side by a negative number.
Given:
An expression,
The sum of a number y and 9 is at least -1.
To find the number in the numerator form,
The sum of y and 9,
y + 9
And the value is at least -1.
So,
y + 9 ≥ 1
Therefore, the inequality is y + 9 ≥ 1

PQRS = ABCD. Which best describes the congruence transformation?
(A) rotation 90° counterclockwise about the origin

(D) rotation 90° clockwise about the origin
Please help! For each of the following relations, identify whether it’s a function or not and why, then state the domain and range.
Answer:
The first one is a function, the second one is a function, and the third one is not a function.
Domain for the first one, just list the x values. Same for range.
Domain and range for the second one are both all real numbers.
For the last one, solve the quadratic, and find the vertex. The range will be all numbers greater than the y on the vertex, while the domain is all real numbers.
Step-by-step explanation:
An easy way to tell if something is a function or not is to check that each input (or x-value) has a different output (or y-value.) The first one is not a function because in the table, we see that 1 gives an output of 9, but later on you see 1 also gives an output of 20.
If you're ever given a graph and asked this question, do the vertical pencil test. Start at the left of the graph, and slide your pencil over the graph (vertically) and if your pencil ever hits more than one point at a time, it's not a function. Hope this helped!

Answer:
1.7 x 10^-27
Step-by-step explanation
Move the decimal to the right until it's a single digit number, because you are moving it to the right, it would be a negative number. If you are able to round up then please do. Remember to check your significant figures if you're in chemistry.

A candy store owner has chocolate candies worth $2.50 per pound and sour candies worth $0.90 per pound. How much of each kind of candies should she combine to get 60 lb of mixed candies worth $1.70 per pound? (Include units with your numerical answers.)
Answer:
Weight of chocolate candies = 30lbs
Weight of sour candies = 30lbs
Step-by-step explanation:
We are told in the question that :
Chocolate candies worth $2.50 per pound
Sour candies worth $0.90 per pound. How much of each kind of candies should she combine to get 60 lb of mixed candies worth $1.70 per pound?
Let x represent the number of pounds of chocolate candies
Let 60 - x represent the number of pounds of sour candies
Hence, we have the equation
x × $2.50 + (60 - x) × $0.90 = 60 × $1.70
= 2.5x + 54 - 0.9x = 102
Collect like terms
2.5x - 0.9x = 102 - 54
= 1.6x = 48
x = 48/1.6
x = 30 lbs
x represent the number of pounds of chocolate candies,
60 - x represent the number of pounds of sour candies
= 60 - 30
= 30lbs
Weight of chocolate candies = 30lbs
Weight of sour candies = 30lbs
Therefore, she should combine 30lbs of chocolate candies and 30lbs of sour candies to get 60 lb of mixed candies worth $1.70 per pound.

A hospital stores one type of medicine in 2-decagram
containers. Based on the information given in the
box above, how many l-milligram doses are there in
one 2-decagram container?
A) 0.002
B) 200
C) 2,000
D) 20,000
Answer:
There are 20,000 milligrams in one 2-decagram container . Thus option D is correct.
Step-by-step explanation:
The given information is one type of medicine in 2 decagram container.
Here, we know ,
1 decagram = 10 grams
and, 1000 milligrams =1 gram
now -: 2 decagram = 2 × 10grams {since 1decagarm = 10 grams }
= 20 grams .
then , = 20× 1000milligrams {since 1 gram = 1000 milligrams}
=20,000 milligrams .
Hence, the correct option is D that is 20,000 milligrams .

10000000000
Step-By-Step:
Convert the decimal into a fraction by putting the decimal over 1 in fraction format
0.1111111111= 0.1111111111 /1
Multiply the numerator and denominator by 10 to eliminate decimal places
0.1111111111 × 10 /1 × 10 = 1.111111111 /10

On her last science test, Mariah missed four questions. For those questions, she received a total of -20 points. On the retake, Mariah missed a quarter of the number of questions that she missed the first time. If the tests were scored the same way, how many points did she receive for missing questions on the retake?
-5
-10
-80
-16
Answer:
5
Step-by-step explanation:
in the beginning, she missed 4 questions and received -20 points. it means that each question missed is equal to -5 points.
So, finally, when she missed 1/4 of the four questions, it means that she missed only one question. So, she only received -5 points

if u pour all the liquid in a cone into a cylinder with the same height and radius then you will fill half of the cylinder with liquid
Answer:
No, the liquid will not fill half of the cylinderStep-by-step explanation:
The volume of a cylinder is 3 times bigger than a cone with equal radius and height
To know this we have to compare the volumes of both solids first.
Let us assume the height and radius of the cone and radius are
6 and 2 mm respectively
so that the volume of a cone is given as
Volume of cone= 1/3 πr^2h
and the volume of cylinder is given as
Volume of cylinder= πr^2h
1. Volume of cone= 1/3 πr^2h
Volume of cone= 1/3 *3.142*(2)^2(6)
Volume of cone= 75.408/3
2. Volume of cylinder= πr^2h
Volume of cone= 3.142*(2)^2(6)
Volume of cone= 75.408
From the analysis the volume of a cylinder is three times bigger the volume of a cone with similar radius and height
What is the best estimate of -15/16 + (-1/2)
Answer:
-23/16
Step-by-step explanation:
Determine the domain of the function (f of g)(x) where f(x)=1/ x+3, g(x) =2/x.
Answer:
(-infinity, -2/3)u(-2/3,0)u(0, infinity)
Step-by-step explanation:
since it is asking for f(g(x)) we plug g into x which looks like:
f(2/x)
now we plug that into the f(x) equation for all of the x's because that is what replaced the x so:
1/(2/x)+3
we look at the denominator so we can pull the 2/x+3 out and set it equal to zero, therefore solving for x
this gives us -2/3
and we get the 0 from g(x) 's denominator
that should be correct and hope this helps!

320÷b∙20 and 320÷(b∙20) for b=4
Answer:
First one equals 16, second equals 4
Step-by-step explanation:
b*20=20b
320/20=16
Second
320/(b*20)
Replace b with 4 so it would be 320/(4*20)
4*20=80, 320/80=4
What is an equation of the line that is parallel to y = 9- 4x and passes through (0, 7)
Answer:
y = -4x + 7
Step-by-step explanation:
Since they are parallel they must have the same gradient which is -4
[tex]y = mx + c[/tex]
m = -4
x = 0
y = 7
7 = -4 × 0 + c
c = 7
[tex]y = - 4x + 7[/tex]
