Answer:
0-2 x-intercepts and 0-1 y-intercepts
Step-by-step explanation:
A quadratic function can have anywhere from 0 to 2 x-intercepts. This is possible because a function can have 0, 1, or 2 solutions.
A parabola can also have either 0 or 1 y intercepts. It is possible for the function to not intercept the y axis at all, and it is also possible for it to intercept it exactly one time.
find 4 different solution for 2x-y-4=0
Answer:
x=3 y=1
x=4 y=2
x=5 y=3
x=6 y=4
Step-by-step explanation:
add y to both sides to get:
2x-4=y
pull out the 2 from 2x-4 to get:
2(x-2)-y = 0
We need to know that x-2 cannot equal 0 or else the solution will be negative. So we need to make x-2 equal to any other number that is not negative and make y the inverse of x-2 so they cancel out and be zero. so some solutions are:
x=3 y=1
x=4 y=2
x=5 y=3
x=6 y=4
Write a function g whose graph represents a reflection in the y-axis of the graph F(x)=-x+1
Answer:
[tex]\bold{g(x) = x+1}[/tex]
Step-by-step explanation:
Given a function:
[tex]F(x) =-x+1[/tex]
To find:
Function [tex]g[/tex] whose graph is a reflection in the y -axis for the given function = ?
Solution:
First of all, let us learn about the reflection of a point ([tex]x, y[/tex]) in y axis.
For example, let us consider a point (3, 2) on the coordinate axis.
The reflection of this point in y axis will be (-3, 2)
OR
In other words, To find the image of a point in y axis:
the x coordinate is made of negative sign and y coordinate remains the same.
A line is nothing but a number of points joined together.
So, if we want to find reflection of a line or linear function in y axis, we just make the sign of x as negative.
Given that [tex]F(x) =-x+1[/tex]
We can write it as:
[tex]F(x)=y =-x+1[/tex]
To find its reflection:
[tex]g(x) = - (-x)+1\\\Rightarrow \bold{g(x) = x+1}[/tex]
Please refer to the attached graphs of [tex]F(x)[/tex] and [tex]g(x)[/tex] .
So, the answer is:
[tex]\bold{g(x) = x+1}[/tex]

Step-by-step explanation:
It takes Jane 65 minutes to fly from Dallas, TX to San Antonio, TX on a commercial airline. She flew a total of 248 miles. Given this information, how long would it take for Jane to fly from San Antonio to Houston, which is 190 miles, if she flies at the same rate? Round to the nearest minute.
Answer:
50 minutes
Step-by-step explanation:
The rate is the same, so the time is proportional to the distance:
time to Houston = (65 min)(190/248) ≈ 49.8 min ≈ 50 min
It would take Jane 50 minutes to fly 190 miles.
Find the GCF of the terms of the polynomial.
====================================================
Explanation:
The GCF of the coefficients {6, -42, 14} is 2 as it is the largest factor found in each of the three values.
----------
For the variable portions, we can
write z^5 as z^3*z^2write z^4 as z^3*z^1write z^3 as z^3*1Each time we see z^3 show up, so this is the largest common factor among the three variable terms.
----------
The two results we got were 2 and z^3
Putting the two results together, we end up with the overall GCF of 2z^3

Step-by-step explanation:
Given.
(4x)/7 - 6 = -20
The x variable should be isolated on one side of the equation.
Adding 6 to both sides of the equation.
(4x)/7 - 6 + 6 = - 20 + 6
(4x)/7 = - 14
Multiplying both sides of the equation by 7.
(4x)/7 × (7) = - 14 × (7)
4x = - 98
Dividing both sides of the equation by 4.
(4x)/4 = - 98/4
x = - 24.5

Hint: | Transform b/c = a so that c only appears in the numerator.
Take the reciprocal of both sides:
c/b = 1/a
Hint: | Solve for c.
Multiply both sides by b:
Answer: c = b/a
5 times the sum of the digits of a two digit number is 9 less than the number formed by reversing its digits. If 4 times the value of the digit at ones place is equal to the half of the place value of the digit at tens place, find out the number.
Answer:
5 times the sum of the digits of the number is 9 less than the number formed by reversing digits. → x = (5y - 9)/4 -- equation (1). Case - 2 : And, 4 times the value of the digits at ones place is equal to half the place value of digit at tens place (10x/2).
Please help Show that the inverse of a linear function y=mx+b, where m≠0 and x≠b, is also a linear function
Let f(x) = mx+b. Also, let g(x) be the inverse of f(x)
To find the inverse, we start with y = mx+b and swap x and y. From there, we solve for y like so
y = mx+b
x = my + b
x-b = my
my = x-b
y = (x-b)/m ... note m is in the denominator, so m cannot be 0
y = (x/m) - (b/m)
y = (1/m)x - (b/m)
g(x) = (1/m)x - (b/m)
This new equation is linear because it is in the form (slope)x+(y intercept)
The new slope is 1/m and the new y intercept is -b/m
So this proves that the inverse g(x) is linear when f(x) is linear.
The inverse function is:
[tex]y = \frac{x}{m} - \frac{b}{m}[/tex]
Since [tex]m \neq 0[/tex] and [tex]x \neq b[/tex], it is a linear function with slope [tex]\frac{1}{m}[/tex] and intercept [tex]-\frac{b}{m}[/tex].
---------------------------------
A linear function is given by:[tex]y = mx + b[/tex]
In which:
m is the slope and b is the y-intercept.To find the inverse function, we exchange x and y in the original function, and then isolate y. Thus:[tex]x = my + b[/tex]
[tex]my = x - b[/tex]
[tex]y = \frac{x}{m} - \frac{b}{m}[/tex]
Since [tex]m \neq 0[/tex] and [tex]x \neq b[/tex], it is a linear function with slope [tex]\frac{1}{m}[/tex] and intercept [tex]-\frac{b}{m}[/tex].

What is the center of a circle with the equation (x − 6)2 + (y + 2)2 = 9?
Answer:
centre = (6, - 2 )
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
(x - 6)² + (y + 2)² = 9 ← is in standard form
with (h, k ) = (6, - 2 ) ← centre
Miguel va de compras al supermercado y adquiere los siguientes productos, 8 helados de crema por un valor de cada uno de $9,56. Un paquete de papas grande por un valor de 3.70. Una gaseosa por valor de 4,525 y una chocolatina por valor de 1,267. 1. ¿Cual es el valor de los ocho helados y que operación debe realizar.? 2. ¿Cual es el valor total que debe pagar en la tienda? 3. Si Miguel tiene en su bolsillo $99,56 cuanto dinero le queda después de pagar en el supermercado?
Answer:
1) El valor de los ocho helados de crema es 76,48 pesos, 2) El valor total de la compra es 85,97 pesos, 3) A Miguel le queda 13,59 pesos después de pagar en el supermercado.
Step-by-step explanation:
Supóngase que los costes son en pesos mexicanos. (MXN)
1) ¿Cuál es el valor de los ocho helados y que operación debe realizar?
Se multiplicar la cantidad de helados comprados por su valor unitario, es decir:
[tex]x = (8\,helados)\cdot \left(9,56\frac{MXN}{helado} \right)[/tex]
[tex]x = 76,48\,MXN[/tex]
El valor de los ocho helados de crema es 76,48 pesos.
2) ¿Cuál es el valor total que debe pagar en la tienda?
El valor total es la suma de todos los costes de los elementos comprados:
[tex]y = 76,48\,MXN + (1\,papa)\cdot \left(3,70\,\frac{MXN}{papa} \right)+(1\,gaseosa)\cdot \left(4,525\frac{MXN}{gaseosa} \right)+(1\,chocolatina)\cdot \left(1,267\,\frac{MXN}{chocolatina} \right)[/tex]
[tex]y = 85,97\,MXN[/tex]
El valor total de la compra es 85,97 pesos.
3) Si Miguel tiene en su bolsillo $99,56. ¿Cuánto dinero le queda después de pagar en el supermercado?
El remanente se obtiene al sustraer el valor total de la compra del efectivo disponible:
[tex]z = 99,56\,MXN-85,97\,MXN[/tex]
[tex]z = 13,59\,MXN[/tex]
A Miguel le queda 13,59 pesos después de pagar en el supermercado.
Which statement is true?

A debt of $17 is a larger value than a debt of $20.
One half an apple is equivalent to 8 fourths apples.
8.01 is a smaller increase in sales then 8.001.
LaTeX: \frac{2}{3} 2 3 below zero is a lower temperature than 6 below zero.
Answer:
The statement that is true is:
A debt of $17 is a larger value than a debt of $20.
Step-by-step explanation:
Let us look at the statements one after the other to determine if they are true or not:
1) A debt of $17 is a larger value than a debt of $20: This is true because when measuring debts, we will consider the values in the negative sense (-). Therefore, a debt of $17 has a value of (-17) and a debt of $20 has a value of (-20). -17 is larger than - 20 on a number line, hence, a debt of $17 has a larger value for the debtor, than a debt of 20$
2) One half an apple is equivalent to 8 fourths apples:
one half an apple = [tex]\frac{1}{2}\ of\ an\ apple[/tex]
8 fourths of an apple = [tex]\frac{8}{4} = \frac{2}{1}\ of\ and\ apple[/tex]. Therefore, one half of an apple is not equivalent to 8 fourth of an apple.
3) 8.01 is a smaller increase in sales than 8.001: This statement is false because 8.001 is counted before 8.01, and the difference between 8.01 and 8.001 is:
8.01 - 8.001 = +0.009, hence, 8.01 is larger than 8.01 by a magnitude of 0.009
4) [tex]\frac{2}{3}\ below\ zero[/tex] is a lower temperature than 6 below zero:
[tex]\frac{2}{3}\ below\ zero\ = (-\frac{2}{3})^\circ[/tex]
6 below zero = - 6°
On the number line, -6 is smaller than [tex]-\frac{2}{3}[/tex] hence the statement is false.

Y/8=5 I don’t know where to start
Answer: y = 40
Explanation: In this problem, notice that y is being divided by 8 so to
get y by itself, we need to multiply both sides of the equation by 4.
So we have (8)(y/8) = (5)(8).
Noice that on the left side, the 8 and 8
cancel each other out so we're just left with y.
On the right side, we have (5)(8) which is 40.
So we have y = 40.
Answer: so what you want to do is you have the equation.
Y/8=5
so you can just say it's Y divided by 8 = 5.
The inverse operation of division is multiplication.
so know it would be y×8=5. so you would multiply 8 by 5. which would be 40 so y=40. a way to check it is subsituting 40 for Y. 40/8=5
