A function of x containing four ordered pairs of the form (x, y) is shown below:
{(2,0), (4, 0), (6,0), (8,0)}
What is the range of the function?
Answer:
Range {0}
Step-by-step explanation:
The range is the set of y values
There is only one y value and it is zero
So the range would be {0}

Lets take
[tex]y = \frac{3}{4} x - 5[/tex]
as L1.
Take L2 the line perpendicular to L1.
Standard form of equation of line:
y=mx+c, where m = slope and c = y-intercept.
Since L1 and L2 are perpendicular,
mL1 x mL2 = -1
Substitute mL1 into the equation,
3/4 x mL2 = -1
mL2 = -1 ÷ 3/4
mL2 = -4/3
L2 : y = mx+ c
Substitute y = 6, x = 8 and m = -4/3 into the equation,
[tex]6 = - \frac{4}{3} (8) + c \\ 6 = - \frac{32}{3} + c \\ c = 6 + \frac{32}{3} \\ = 16 \frac{2}{3} [/tex]
therefore L2:
[tex]y = - \frac{4}{3}x + 16 \frac{2}{3} [/tex]
Lets take L3 as the line parallel to L1.
Since L3 and L1 are parallel,
mL3 = mL1 = 3/4
equation of line: y = mx+c
substitute y = 6, x = 8 and m = 3/4 into equation.
[tex]6 = ( \frac{3}{4} )(8) + c \\ 6 = 6 + c \\ c = 6 - 6 \\ = 0[/tex]
therefore L3:
[tex]y = \frac{3}{4} x[/tex]

the hotog eating champion eats 27.5 hot dogs in 4 minutes. at that rate how many does he eat in the 10 min competition?
Answer:
68.8 hot dogs
Step-by-step explanation:
27.5 ÷ 4 = 6.875 per minute
6.875x10 = 68.75 hot dogs
Answer:
68.75 hotdogs
Step-by-step explanation:
lets say x = number of hotdogs
27.5/4 = x/10
use cross multiplication:
27.5 (10) = 4(x)
multiply
275 = 4x
divide both sides by 4 to isolate x
x = 68.75
Joseph has only nickels and quarters in his piggy bank. He has 62 coins total for a
combined value of $11.10. How many nickels does Joseph have?
9514 1404 393
Answer:
22 nickels
Step-by-step explanation:
Let n represent the number of nickels in Joseph's piggy bank. Then the number of quarters is 62-n. The total value is ...
0.05n + 0.25(62 -n) = 11.10
-0.20n + 15.50 = 11.10 . . . simplify
4.40 = 0.20n . . . . . . . . . . add 0.20n-11.10
4.40/0.20 = n = 22
Joseph has 22 nickels in his piggy bank.
The quadrtic expression x^2-2x-35 can be factored into (x+5)(x-7). Which ordered pairs represent the zeros of this expressionś related quadratic functions
Answer:
The ordered pairs of [tex]p(x) = x^{2}-2\cdot x -35[/tex] are [tex](r_{1}, p(r_{1})) = (-5, 0)[/tex] and [tex](r_{2},p(r_{2})) = (7,0)[/tex], respectively.
Step-by-step explanation:
Let be [tex]p(x)[/tex] a quadratic expression whose two real zeros are real, a value of [tex]x[/tex] is a zero of the expression when [tex]p(x) = 0[/tex]. The factored form of the expression is represented by [tex]p(x) = (x-r_{1})\cdot (x-r_{2})[/tex], where [tex]r_{1}[/tex] and [tex]r_{2}[/tex] are the zeroes of the polynomial.
If [tex]p(x) = x^{2}-2\cdot x -35[/tex], then the ordered pairs that represent the zeros are:
[tex](r_{1}, p(r_{1})) = (-5, 0)[/tex] and [tex](r_{2},p(r_{2})) = (7,0)[/tex]
Quadratic equation has a leading coefficient of the second degree. The ordered pairs of the quadratic equation are (-5,0) and (7,0).
What is a quadratic equation?A quadratic equation is an equation whose leading coefficient is of second degree also the equation has only one unknown while it has 3 unknown numbers.
It is written in the form of ax²+bx+c.
As the factors of the quadratic equation are given, therefore, equating the factors with zero in order to get the value of x.
[tex](x+5)=0\\x = -5[/tex]
[tex](x-7)=0\\x = 7[/tex]
Now, if we see the quadratic equation or the function it is written as,
[tex]y = x^2-2x-35 \\\\ x^2-2x-35 = 0[/tex]
Therefore, the value of y is 0.
Thus, the ordered pairs of the quadratic equation are (-5,0) and (7,0).

simplify: ,3(x-2) + 2(2x+5) =32, a+2a+7a
Answer:
x = 4, 10a
Step-by-step explanation:
3(x-2) + 2(2x+5) = 32
3x - 6 + 4x + 10 = 32
3x + 4x + 10 - 6 = 32
7x + 4 = 32
7x = 32 - 4
7x = 28
Divide both side by 7
x = 4
a + 2a + 7a
They are common because the have the same variables.
'a' is with a coefficient of 1
You add the coefficient and attach the variable to it
Therefore,
a + 2a + 7a = 10a

Step-by-step explanation:
For seg FG to be tangent to the circle with center E, the side lengths 6, 10, 12 must follow the rule of Pythagorean triplets.
So,
[tex] {10}^{2} + {6}^{2} = 100 + 36 = 136 \\ \\ {12}^{2} = 144 \\ \\ \because \: {10}^{2} + {6}^{2} \neq \: {12}^{2} \\ [/tex]
From above it is obvious that given segment lengths doesn't follow the Pythagorean triplet rule. Therefore, seg FG is not tangent to the circle with center E.

A pet store employee measures the lengths of two pet snakes, Noodles and Squiggles. Noodles measures 30 inches long, and Squiggles measures 2 feet 10 inches long. Which snake is longer, and by how much?
Answer:
4
Squiggles
Step-by-step explanation:
steps
convert the length of squiggles from feet to inches find the difference1 feet = 12 inches
2 feet = 2 x 12 = 24 inches
length of squiggles = 24 + 10 = 34 inches
squiggles is longer because 34 is greater than 30
difference = 34 - 30 = 4

A television channel broadcasts a baseball game every day. Yesterday's broadcast showed the game for 2 5/6 hours and commercials for 2/3 hour. At this rate, how many hours does the television channel show a game for every hour it shows commercials during its broadcasts?
Answer:
4.25 hours
Step-by-step explanation:
Given that :
Game broadcast time = 2 5/6 hours = 17/6 hours
Commercials time = 2/3 hours
2/3 hours of commercials = 17/6 of game broadcast
1 hour of commercials = x hours of game broadcast
Cross multiply ;
(2/3)x = 17/6
2x * 6 = 17 * 3
12x = 51
x = 51 / 12
x = 4.25
For every hour it shows commercials, game is broadcasted for 4.25 hours

Write an equation of a line with the given slope and y-intercept.
m = –1, b = –6
A.
y = –x – 6
B.
y = x + 6
C.
y = –6x – 1
Answer: here is the answer
The equation of the line that has a slope of -1 and a y-intercept of -6 is:
y=-1x-6.
Step-by-step explanation: here is the explanation
You want to find the equation for a line that has a slope of -1 and a y-intercept of -6.
First of all, remember what the equation of a line is:
y = mx+b
Where:
m is the slope, and
b is the y-intercept
All you really have to do here is
replace m with -1, which is the slope you gave, and
replace b with -6, the y-intercept you gave,
in the equation y=mx+b.
The equation of the line that has a slope of -1 and a y-intercept of -6 is:
y=-1x-6.
The first three terms of a sequence are given. Round to the nearest thousandth (if necessary) 210,206,202,... Find the 35th term.
Answer:
u1 = 210
u2 = 206 = u1 - 4
u3 = 202 = u2 - 4
........
un = u1 - 4(n - 1) = 214 - 4n
so the 35th term is 214 - 4.35 = 214 - 140 = 74
I need this ASAP What is the image of the point (-7,-3) after a rotation of 180 counterclockwise about the origin?
The coordinates of the image after a rotation of 180° counterclockwise about the origin is A' ( 7 , 3 )
What is Rotation?The measure of the amount a figure is rotated about the center of rotation is called the angle of rotation. The angle of rotation is usually measured in degrees. We specify the degree measure and direction of a rotation.
90° clockwise rotation: (x,y) becomes (y,-x)
90° counterclockwise rotation: (x,y) becomes (-y,x)
180° clockwise and counterclockwise rotation: (x, y) becomes (-x,-y)
270° clockwise rotation: (x,y) becomes (-y,x)
270° counterclockwise rotation: (x,y) becomes (y,-x)
Given data ,
Let the coordinate of the point be A
Now , the value of A is A ( -7 , -3 )
And , 180° clockwise and counterclockwise rotation: (x, y) becomes (-x,-y)
So , the coordinates of the image is A'
And , the value of A' = A' ( 7 , 3 )
Hence , the rotation is solved and the image is A' ( 7 , 3 )
