Answer:
The answer is
C. The mapping represents y as a function of x, because each x-value corresponds to exactly one y-value.
Step-by-step explanation:
In mathematics, mapping is used synonymously to a function, and a function is basically a relation between two values or expressions say y and x
like the difference equation relating y and x.
In a function, for every value of x plugged into the function there is always a corresponding value of y.
Example.
Given the function
y=2x+5.
find the value of y when x=0
we are going to substitute x=0 and solve
y=2(0)+5
y=5
so for x=0 y=5
A line contains the points (−26, −37) and (−32, −61).
What is the slope of the line in simplified form?
Answer:
The slope of the line is 4
Step-by-step explanation:
You use the equation Y2 - Y1/ X2 -X1 to find the slope.
-61-(-37)/-32 - (-26)
-24/-6
4
Answer:
The answer is 4
A rectangle has perimeter 68 cm and length 25 cm. What is its width? In centimeters.
Answer: 9cm
Step-by-step explanation:
Answer:
18
Step-by-step explanation:
To find it you must multiply the length by 2
25 × 2 = 50
Then subtract the result with the perimeter
68-50 = 18
And the result of that is your answer
8/19 +4/24

Yes.
Step-by-step explanation:
Answer:
Yes
Step-by-step explanation:
Let's compare these numbers as decimals to make it easy. -16/5 as a decimal is -3.2. It's a negative number, therefore it is smaller than the positive number. The positive number (3.54) is bigger.

5(3x+8)=175
with steps pls
Answer:
x=9
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
5(3x+8)=175
(5)(3x)+(5)(8)=175(Distribute)
15x+40=175
Step 2: Subtract 40 from both sides.
15x+40−40=175−40
15x=135
Step 3: Divide both sides by 15.
15x/15=135/15
x=9

*PLEASE HURRY* WILL GIVE BRAINLIEST* Write the equation in the form ax^2 + bx+c=0 where a > 0, if necessary. Then identify the values of a, b, and c. Do not actually solve the equation
3x^2 = 4x + 8
Answer:
a= 3
b=-4
c=-8
Step-by-step explanation:
3x²=4x+8
since the 4X is positive it will cross the equal sign and become negative and the same goes for 8,and this will leave nothing on the right of the equal sign therefore it will become 0
3x²-4x- 8= 0
the above equation is now in the form required
ax²+bx+c=0
so substitute the values according and u will see that a= 3
b=-4 and c=-8
hope this helps

I’ve been able to figure out the rest of the questions but this one has me stumped. I need to solve for x. Can someone please write the steps down so I can learn what to do?
Answer:
X= -11
Step-by-step explanation:
Combine the two equations to equal a supplementary line
(X+91)=(x+111)=180
Solve for x by reversing the equation
(x)+(x)=(180-91)+(-111)
x=-22/2
x=-11
then check it

Answer:
1 of 8: (729, 81, 9, 1)
2 of 8: 1 = (-1)^0 = 2^0
3 of 8: 1
Step-by-step explanation:
The basic rule is that any non-zero value to the zero power is 1. It doesn't matter whether the value is positive or negative. Raising it to the zero power makes it 1.
So, for question 2 of 8, the two equivalent expressions can be anything raised to the zero power (or anything with a value of 1, for that matter).

In the order of the attachments, ...
3) 5^0 = 1
2) (-5.7)^0 = 1
two other expressions could be (-1)^0 and 2^0.

you purchase 3 t-shirts and a booklet for 90$. the booklet cost 15. how much is each t-shirt? please help ! thank u
Answer:
each t-shirt was $25
Step-by-step explanation:
90 minus 15 = 75
75 divided by 3 equals 25
Answer:
25
Step-by-step explanation:
3t+15=90
3t=75
t=25
t represents the price for one t-shirt. 90 is the total amount and if the booklet is 15 dollars, altogether they equal 90. With this equation you are trying to isolate the variable (t), so subtract 15 because the opposite of 15 is -15. Then divide that by 3 because 3t is also 3 times t and the opposite of times is division.
