There's a trick to solve these graph questions
Solve the given quadratic equations in the options , the points which match with the changed graph will be the final option
if you solve the first option F(x) = x2-2
you'll get x = +2 and -2
as you can see , the Fx graph cuts the x axis at +2 and -2 and thus option A is correct
thankyou

Andrew has $40. He wants to buy a $15 CD and as many $6 posters as he can. What is the greatest number of posters Andrew can buy?
write the equation.
(example 3 - 4 > 5)
Answer:
x<5
Step-by-step explanation:
since the CD is a one time purchase, his total amount of money after would be 25.
40-15>6x
25>6x (still have to solve for x)
4.166>x
x<5 (since it has to be a whole number)

Hey can u help me with this question
Answer:
y = 3x - 1
Step-by-step explanation:
→ Substitute x = 1 into all the equations to get y = 2
y = 3x - 1 ⇔ ( 3 × 1 ) - 1 = 2
Answer:
D
Step-by-step explanation:
You can answer this question without even worrying about slope if you know how the y-intercept should be. The y-intercept is where the line crosses the y-axis(the vertical line with the y label in case that needs to be explained.) With that alone, you can determine that the y-intercept is -1 and thus the answer is D. For the slope, try to find a point on the line that is on the grid (A good one is (0,-1) ). Then move from that point to the next point where two of the lines meet like (1,2). Slope is rise/run so you go 3 up and 1 to the right for 3/1 which equals 3.

Complete the Law Of Sines Select the value that belongs to the green box, please somebody!
Answer: [tex]\frac{a}{\sin(A)} = \frac{b}{\sin(B)} = \frac{c}{\sin(C)}[/tex]
The sin(A) goes with 'a'
sin(B) goes with b
sin(C) goes with c
Each angle goes with the corresponding side to form the three fractions shown. You can break up that triple equation into smaller equations such as [tex]\frac{a}{\sin(A)} = \frac{b}{\sin(B)}[/tex] and [tex]\frac{b}{\sin(B)} = \frac{c}{\sin(C)}[/tex] and [tex]\frac{a}{\sin(A)} = \frac{c}{\sin(C)}[/tex]
Note: if you apply the reciprocal to all three sides, then you'll get an equivalent equation. I'm using the rule that A/B = C/D is the same as B/A = D/C.
Describe the leading coefficient,
a
for the quadratic function shown in the graph below.
12
x
The leading coefficient of the quadratic function a is negative
How to describe the leading coefficient?From the graph, we have the following points:
Vertex, (h,k) = (-4,3)
Point, (x,y) = (-3,2)
A quadratic equation is represented as:
y = a(x - h)^2 + k
So, we have:
2 = a(-3 + 4) + 3
Subtract 3 from both sides
-1 = a(-3 + 4)
Evaluate the difference
-1 = a
This gives
a = -1
Hence, the leading coefficient a is negative

which expression is equivalent to 4 start root 81/16 a^8 b^16 c^16?
so i know g(x)=3k-2x² and g(-3)=-6
how do i know what g(x) ad k are?
Answer:
find k by putting -3 where there is x than -6 on g(x)
Step-by-step explanation:
g(x)=3k-2x²
-6=3k-2(-3)²
-6=3k-18
-6+18=3k

What is the measure of angle 1?
Answer:
C
Step-by-step explanation:
Let find the measure of the angle supplementary to Angle 1.
[tex] \frac{123 + 84}{2} = 103.5[/tex]
Angle 1 is supplementary to that angle so
[tex]103.5 + x = 180[/tex]

Answer:
1/6
Step-by-step explanation:
6^-2 / 6^-1
We know that a^b / a^c = a^(b-c)
6^(-2 - -1) = 6^(-2+1) = 6^-1
We know that a^-b = 1/a^b
1 /6^1 = 1/6
Answer:
1/6
Step-by-step explanation:
When dividing by exponents, you need to subtract the exponent from top to bottom. Ex: 5^3/5^2=5^1 which is just one, because you subtract 3 and two. In this case, 6^-2 / 6^-1 gets us 6^-1 which is the same thing as 1/6^1. Because remember, a^-x = 1/a^x.

What is the common ratio of the following sequence?
-1, 6, - 36, 216 . . .
r = -6
r = 1296
r = -1
r = 7
Answer:
r = -6
Step-by-step explanation:
-1 × -6 = 6
6 × -6 = -36
-36 × -6 = 216
Answer:
-6
Step-by-step explanation:
To find the common ratio, take the second term and divide by the first term
6/ -1 = -6
Check the third term and divide by the second term
-36/-6 = -6
And the 4th divided by the third
216/ -36 = -6
The common ratio is -6

Si Doña Clara lleva un tratamiento con 2 medicamentos una toma cada 8 horas y la otra toma cada 12 horas, ¿Despues de la primera toma, a las cuantas horas volverá a tomar los dos medicamentos?
Respuesta:
24 horas
Explicación paso a paso:
El primer medicamento se toma cada 8 horas.
El segundo medicamento se toma cada 12 horas.
Para Obtian el momento en que ambos medicamentos se volverán a tomar juntos:
Encontramos el mínimo común múltiplo de 8 y 12
Múltiplos de:
8 = 8, 16, 24, 32, 40, 48, 56
12 = 12, 24, 36, 48, 60
El mínimo común múltiplo de 8 y 12 es 24.
Por lo tanto, ambos medicamentos se volverán a tomar después de 24 horas.
