A parabola has a vertex at (0,0). The equation for the
directrix of the parabola is x = -4. In which direction does the parabola open?
Answer:
Right.
Step-by-step explanation:
The answer is right on edge2020 I just took the test.
The direction in which the parabola will open is; To the right
What is the equation of a parabola?We are given;
The vertex of the parabola is at (0, 0)
Directrix of the parabola is x = -4
We know that when the vertex of the parabola is (0, 0) and the directrix is x = - a, the parabola will have the form;
y² = 4ax
Thus, we can conclude that the parabola opens towards the right.

-8m - 12 > -5(m - 8) – 3(m - 7)
Write the solution to the inequality
Answer:
No answer.
Step-by-step explanation:
- 8m - 12 > -5m + 40 - 3m + 21
combine terms
-8m - 12 > -8m +61
add 8m to both sides
-12 > 61

Un hacendado a comprado doble numero de vacas que de bueyes, por cada vaca pago 70 dólares y por cada buey 85 dólares, si el importe de la compra fueron 2,700 dólares cuantas vacas y bueyes compro
Responder:
Número de bueyes = 12
Número de vacas = 24
Explicación paso a paso:
Dado que :
Número de vacas compradas = 2 veces el número de bueyes;
Sea número de bueyes = y
Número de vacas = 2 años
Costo de la vaca = 70
Costo de bueyes = 85
Costo total = 2700
Por lo tanto;
(2 años * 70) + (y * 85) = 2700
140 años + 85 años = 2700
225 años = 2700
225 años / 225 = 2700/225
y = 12
Número de bueyes = y = 12
Número de vacas = 2y = 2 * 12 = 24

The diagram shows a circle drawn inside a square.
The circle touches the edges of the square.
18 cm
Calculate the total shaded area.
Take it to be 3.142 and write down all the digits given by your calculator.
Answer:
69.498
Step-by-step explanation:
first find the area of the whole square (how i saw it), remember
it is made up of a circle drawn inside a square.
so we do the area of the square = 18²
= 324
next we find the circle which was drawn, the circle covers up the
whole shaded square.
diameter would be 18 as the length of the square was 18,
then we find the radius, 18/2 = 9
now we use πr²,
r would be the radius (9)
therefore it would be π(81) and we get 254.502
now we take away the area of the circle covering the square
from the area shaded in,
therefore 324 - 254.502
= 69.498

Answer:

Step-by-step explanation:
The predicted amount is for the second button only.
Each dollar spent does not always earn the same number of points.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Customers of a certain credit card earn points for using the card.
The table shows the number of points earned for the amount spent.
Now, By the given table which shows the number of points earned for the amount spent.
⇒ Number of points in 4 dollars = 36
Hence, Number of points in 1 dollars = 36/4 = 9
⇒ Number of points in 7 dollars = 56
Hence, Number of points in 1 dollars = 56/7 = 8
⇒ Number of points in 9 dollars = 72
Hence, Number of points in 1 dollars = 72/9 = 8
Thus, We get;
⇒ Each dollar spent does not always earn the same number of points.

What is the value of f(3) ?
Answer:
f(3)=-60
Step-by-step explanation:
f(3)=5*(3^2)-7(4*3 + 3)
f(3)=5*9 - 7*15
f(3)=45-105
f(3)=-60
Answer: -60
Step-by-step explanation:
f(3) means that you replace the input function of x with 3; So, your equation would look something like this:
5(3)^2 - 7(4(3) +3)
= 5(9) - 7(15)
= 45 - 105
= -60

company B = 36,000 + 2,000 (x)
where x = no. of years.
company A = company B28,000 + 3,000 (x) = 36,000 + 2000 (x)
3,000 (x) - 2,000 (x) = 36,000 - 28,000
1,000 (x) = 8,000
x = 8,000
