Answer: The function is not one-to-one
Step-by-step explanation:
An one-to-one function is such that no two elements in the domain correspond to the same element in the range.
Now, we have the function:
y = f(x) = round(x)
Which rounds x to the nearest whole number.
Now, to round to the next whole number we must look at the first number after the decimal point.
If that number is 5 or larger, we round up
If that number is smaller than 5, we round down.
Then, for example:
f(1.2) = 1
because the first number after the decimal point is smaller than 5.
and:
f(1.1) = 1
f(1.2) = 1
f(1.2423) = 1
f(1.348) = 1
So we have a lot (if x is real, we have infinite) values of x that are maped into the same value in the range.
Then this can not be an one-to-one function.
A student's cost for last semester at her community college was $2000. She spent $340 of that on books. What percent of last semester's college costs was spent on books?
Answer:
17%
Step-by-step explanation:
2000-340= 1660
1660/2000= 83% (1660 is 83% of 2000)
100%-83%= 17% so 17% of 2000 is 340.

Answer:
-5 ⁷/12
Step-by-step explanation:
-⁷/12+ -5
-5 ⁷/12
Answer:
Mixed Number: -5 7/12
Improper Fraction: -67/12
Step-by-step explanation:
-7/12 + (-5)
-7/12 - 5/1
Change so they have a common denominator
-7/12 - 60/12
= -67/12
= -5 7/12

Answer:
Step-by-step explanation:
L=k/m + 2R
L-2R=K/m
K=m(L-2R)
L=4800 , R=290 , m=5/12
K=m(L-2R)
K=5/12 ( 4800-2(290))
K=5/12 (4800-580)
K=5/12(4120)
K=5275/3=1758.3

HELP!!! BRAINLIEST!!The expression on the left side of an equation is shown below.
Negative 4 (x minus 2) + 5 x = box
If the equation has no solution, which expression can be written in the box on the other side of the equation?
Answer:
Expression that can be written in the box on the other side of the equation will be x
Step-by-step explanation:
The left side of equation is:
Simplifying the equation we get:
An equation has no solution when, we cannot find the value of x.
So, The order side of equation can be x
i.e,
So, expression that can be written in the box on the other side of the equation will be x
Answer:
X is your answer

Ryan shaded 70 squares on his hundredths grid. Sarah shaded 80 squares on her hundredths grid.
This image shows two hundredths grid next to each other. First hundredth grid has 70 squares shaded in blue and remaining are empty and second hundredth grid has 80 squares shaded in red and remaining are empty.
Part A
Which value is greater than Ryan’s decimal and less than Sarah’s decimal?
70100+4100 60100+5100 80100+1100 80100+15100
Part B

Answer:
0.7
Step-by-step explanation:
Answer:
A. 70/100 +4/100
B. 0.700, 0.7, 0.70
Step-by-step explanation:
A. The number between Ryan's 70/100 and Sarah's 80/100 will be 70/100 + some number less than 10/100, such as ...
70/100 +4/100
__
B. Trailing zeros (or their lack) don't change the value. Ryan has 70/100 = 0.70 of the grid shaded. Equivalent numbers are ...

A publisher sells digital copies of their new book, paperback copies or barnacle copies. For every 4 digital sales they make, they make 5 paperback sales and 1 hardback sale. In the first week of sales, the company sells 307 more paperback copies of the book than hardback copies. How many total copies of the book did the company make in week 1?
Answer:
Step-by-step explanation:
A publisher sells digital copies of their new book, paperback copies or barnacle copies.
Digital sales = d
Paper back sales = p
Hard back sales = h
For every 4 digital sales they make, they make 5 paperback sales and 1 hardback sale.
In the first week of sales, the company sells 307 more paperback copies of the book than hardback copies.
p = 307 + h
How many total copies of the book did the company make in week 1?
#2 Find the measure of x.
Answer:
60 degrees
Step-by-step explanation:
Since all the sides are congruent it is an equilateral triangle and all equilateral triangles have angles of 60 degrees.
Another way to solve it is knowing that if all sides are congruent that means all angles are congruent. Then doing 180/3 because all triangles have 180 degrees and there are three equivalent angles.

When factored, the trinomials x2 + 4x − 21 and x2 + 11x + 28 have one binomial factor in common. What is this factor?
x − 7
x + 7
x − 5
x + 5
Helpppppp
Answer:
x + 7
Step-by-step explanation:
x^2 + 4x − 21 =
= (x + 7)(x - 3)
x^2 + 11x + 28 =
= (x + 4)(x + 7)
Answer: x + 7

I tried doing 180-67= 113 divided by 2 but it didn’t work
Answer:
no need to divide by 2.
Step-by-step explanation:
let's see u will understand.
solution,
x+67=180 (being straight line)
or, x=180-67
x=113 answer.
hope it'll help you.
Answer:
113°
Step-by-step explanation:
x and the angle with 67° are complementary angles and their sum is equal to 180°
x + 67 = 180 subtract 67 from both sides
x = 113°
40 inches to 4 feet as a fraction without units
Answer:
3 1/3
