Answer: Rational Numbers are the Numbers where if p/q, q is not equal to 0 and p is an integer. So according to this questionm denominators can’t have the negative rational numbers. If it has, we need to convert it to standard form, eg:- p/-q = -p/q
Answer:
Yes
Step-by-step explanation:
[tex]A \ rational \ number \ is \ a \ number\ of\ the\ form\ \frac{p}{q}, \\\\where\ p\ and\ q \ are\ integers\ and\ q \ not\ equal \ to\ zero.\\\\That\ means\ q\ can\ take\ any\ number\ positive\ or\ negative\ but\ zero.[/tex]

What is the axis of symmetry for the function f(x)=7−4x+x2?
x = –3
x = –2
x = 2
x = 3
Answer:
Answer:
x = 2
Step-by-step explanation:
The vertex form of the parabola is given by
Comparing this equation with vertex form of a parabola , where (h,k) is the vertex
h = 2
k = 3
Hence, vertex is (2,3)
Now, axis of symmetry of a parabola passes through the vertex and divide the parabola in two equal halves.
Hence, axis of symmetry of the parabola is given by
x = h
x = 2
Third option is correct.

Sharma is three years older than Anand. Six years ago Sharma's age was four times Anand's age. Find their ages?
Answer:
See explanation
Step-by-step explanation:
Anand = x
Sharma = x + 3
6 years ago
Anand = x - 6
Sharma = (x + 3) - 6
= x + 3 - 6
= x - 3
Sharma age = 4 (x - 6)
Six years ago Sharma's age was four times Anand's age.
x + 3 = 4(x - 6)
x - 3 = 4x - 24
x - 4x = -24 + 3
- 3x = - 21
x = - 21/-3
x = 7
Anand = x = 7 years
Sharma = x + 3
= 7 + 3
= 10 years

Bryan hiked to a famous point with a beautiful view. It took 2 hours and 20 minutes to hike to the viewpoint and 1 hour to hike back. Bryan spent 1 hour and 10 minutes enjoying the view at the top. He finished the hike at 2:55 P.M. What time did Bryan start the hike to the viewpoint?
Answer:
Bryan stated the hike to the viewpoint at 10:25 A.M.
Step-by-step explanation:
One hour to hike back:
So he stopped enjoying the view at 1:55 P.M(one hour before 2:55 P.M).
1 hour and 10 minutes enjoying the view at the top.
So he arrived there at:
12:45 P.M.(1 hour and 10 minutes before 1.55 P.M).
2 hours and 20 minutes to hike to the viewpoint and 1 hour to hike back.
So he started hiking at:
10:25 A.M(2 hours and 20 minutes before arriving to the viewpoint).
Bryan stated the hike to the viewpoint at 10:25 A.M.
Find the value of 'x' then calculate the measure of angle C(2x + 15) in the triangle below.
Answer:
x = 33
<C = 81
Step-by-step explanation:
The sum of the angles of a triangle add to 180
x+ 2x+ 2x+15 = 180
Combine like terms
5x+15 = 180
Subtract 15 from each side
5x +15-15 =180-15
5x = 165
Divide by 5
5x/5 =165/5
x = 33
<C = 2x+15 = 2(33)+15 = 66+15 = 81
Answer:
x = 33
c = 81
Step-by-step explanation:
Sum of three angles of triangle = 180
x + 2x + 2x + 15 = 180
Combine like terms
5x + 15 = 180
Subtract 15 from both sides
5x = 180 - 15
5x = 165
Divide both sides by 5
x = 165 /5
x = 33
∠C = 2x + 15 = 2*33 + 15 = 66 + 15 = 81°
PLEASE HELP! SEE PHOTO FOR QUESTION
Answer:
A
Step-by-step explanation:
Intercepts are basically points where if one of the coordinates is a number above 0, the other one HAS TO BE 0
Since there are three points where there are x-intercepts (since the y is 0), there will be three x-intercepts.
Since there is only one point where there are y-intercepts (since the x is 0), there will be only one y-intercept.
The intercepts don't give an exact answer so you would have to estimate where they are on the graph. For example, the y-intercept is between 20-30 and is leaning more towards 30, so you would think it's around 27-29 (And if you look at option A, you can see that it's (0,28))
You got the answer wrong because for one of the x-intercepts, you said that it was negative when it was actually positive. (I believe it was the (2.3,0) one.)

Write the equation in standard form for the circle x2 + 32 = -y² + 12x.
Step-by-step explanation:
Move
26
to the right side of the equation because it does not contain a variable.
3x2−12x−2y2+16y=26
Answer:
(x - 6)² + y² = 4
Step-by-step explanation:
x² + 32 = -y² + 12x
Rearrange
x² - 12x + y² = -32
Complete the square for x
(x - 6)² + y² = -32 + (-6)²
(x - 6)² + y² = -32 + 36
(x - 6)² + y² = 4

Se tienen 25 billetes de 5 y de 20 lempiras con un monto de 350 lempiras cuantos billetes de 5 lempiras se tienen y de 20 lempiras
Answer:
El número de facturas
5 lempiras = 10 billetes
20 lempiras = 15 billetes
Step-by-step explanation:
Vamos a representar
El número de facturas de
5 lempiras = x
20 lempiras = y
Nuestro sistema de ecuaciones se da como:
x + y = 25 ..... Ecuación 1
x = 25 - y
5 × x + 20 × y = 350
5x + 20y = 350 .... Ecuación 2
Sustituiríamos x por 25 - y en la ecuación 2
5 (25 - años) + 20y = 350
125 - 5 años + 20 años = 350
125 + 15 años = 350
15 años = 350 - 125
15 años = 225
y = 225/15
y = 15
Resolviendo para x
x = 25 - y
x = 25 - 15
x = 10
Por lo tanto, el número de facturas
5 lempiras = 10 billetes
20 lempiras = 15 billetes

I have this math problem and it is: an equation in function from that reflects f(x)=3x over the line y=0.
Answer:
[tex]g(x) = -3x[/tex]
Step-by-step explanation:
Given
[tex]f(x) = 3x[/tex]
Required
Reflect over [tex]y = 0[/tex]
This means that we reflect over the x-axis
And the rule of reflection is:
[tex](x,y) \to (x,-y)[/tex]
Hence:
[tex]f(x) = 3x[/tex]
Will become:
[tex]g(x) = -f(x)[/tex]
So, we have:
[tex]g(x) = -3x[/tex]
A line with a slope of 0 passes through the points (–4,q) and (6,–10). What is the value of q?
Answer:
q = - 10
Step-by-step explanation:
A line with a slope of zero is a horizontal line parallel to the x- axis
The y- coordinates of the points the line passes through are equal
Given the line passes through (- 4, q) and (6, - 10 ) with y- coordinate - 10
Then q = - 10
