Answer:
ANSWER:
{(2,4),( 3, 6),(4, 8)} is a function
Given a relation in x and y, we say y is a function of x if for each element x in the domain, there is exactly one value of y in the range. It is a rule of correspondence between two nonempty sets, such that, to each element of the first is called domain, there correspondents one and only one element of the second is called range.
To determine whether it is function or not by using the vertical line test. If the graph passed to Vertical line test it is consider as function. The graph of function defines y as a function of x if no vertical line intersects the graph in more than one point.
The first set of ordered pairs is a function, because no two ordered pairs have the same first coordinates with different second coordinates for example ( -1, 2), ( 1, 0), (2, 1) . The second example is not a function, because it contains the ordered pairs (1,2) and (1,4). the first set is repeated . These have the same first coordinate and different second coordinates.
The range of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain. The range is the resulting y-values we get after substituting all the possible x-values.

Find the slope. Make sure to reduce.
Answer:
The slope here is undefined.
Step-by-step explanation:
The two points shown here are (4, 0) and (4, 1). To find the slope do (y B − y A) /(x B − x A).
(1 - 0)/(4 - 4)
Any number subtracted by 0 gets you itself. Any number subtracted byt he same number gets you zero.
1/0
You can't divide by zero, so the slope is undefined.
Reflection over the line y = -x of the point (1,3)
Answer:
(-3,-1)
Step-by-step explanation:
To reflect them you gotta switch their places and change their signs from positive to negative.
so (x,y) -> (-y,-x)

do i add 40 + 45? Or multiply
Answer:
you add 40+45
Step-by-step explanation:
40+45=85
then you subtract 180 - 85 = 95
then divide x into 95 that will give you x=95

When placed near a second charge, a 60-μC charge experiences a force of 0.30 N. What is the electric field strength at the location of the 60-μC charge? What is the strength of the electric field at the location of the test charge?
Answer:
[tex]E=5000N/C[/tex]
Step-by-step explanation:
From the question we are told that
Charge [tex]q= 60 \mu C[/tex]
Force [tex]F_=0.30N[/tex]
Generally the equation for electric field strength is mathematically given as
[tex]E=F/q[/tex]
[tex]E=\frac{0.30}{60*10^-^6}[/tex]
Therefore
[tex]E=5000N/C[/tex]
The normal price of a bicycle is £120
In a sale, there is 1/5 off the normal price of the bicycle.
Work out the price of the bicycle sale?
Answer:
76
Step-by-step explanation:
100% = 120
1/5 of 100% = 20%
20% = 120÷100×20
= 24
100-24= 76

solve the simultaneous Equation
3/x- 4/y= 1/3
Answer:
a simultaneous equation is a set of equations. you need at least another equation.
Answer:
Step-by-step explanation:
Let's solve for x.
3x−4y= 1/ 3
Step 1: Add 4y to both sides.
3x−4y+4y= 1/ 3 +4y
3x=4y+ 1/ 3
Step 2: Divide both sides by 3.
3x/ 3 = 4y+ 1/ 3
3 x= 4/ 3 y+ 1/ 9
Answer:
x= 4/ 3 y+ 1/ 9
Let's solve for y.
3x−4y= 1/ 3
Step 1: Add -3x to both sides.
3x−4y+−3x= 1/ 3 +−3x
−4y=−3x+ 1/ 3
Step 2: Divide both sides by -4.
−4y/ −4 = −3x+ 1/ 3
−4 y= 3/ 4 x+ −1/ 12
Answer:
y= 3/ 4 x+ −1/ 12

La suma de las edades de los hermanos Carlos y Felipe es igual a la edad de su tía María; Si María tiene 29 años y Carlos tiene 13 años, ¿Cuántos años tiene Felipe?
Answer:
16 años
Step-by-step explanation:
Si la suma de la edad de Carlos y Felipe es igual a la de Maria, y en la pregunta nos dan la edad de Maria (M) y Carlos (C), entonces tenemos que encontrar la edad de Felipe. Para calcular esto necesitamos restar la edad de Carlos de la edad de Maria. Esto nos dara la edad exacta de Felipe (f).
M - C = f
29 - 13 = f
16 = f
Finalmente, vemos que la edad de Felipe es de 16 años
