Answer:
The quadratic function whose graph contains these points is
Step-by-step explanation:
We know that a quadratic function is a function of the form . The first step is use the 3 points given to write 3 equations to find the values of the constants <em>a</em>,<em>b</em>, and <em>c</em>.
Substitute the points (0,-2), (-5,-17), and (3,-17) into the general form of a quadratic function.
We can solve these system of equations by substitution
- Substitute
- Isolate a for the first equation
- Substitute into the second equation
The solutions to the system of equations are:
b=-2,a=-1,c=-2
So the quadratic function whose graph contains these points is
As you can corroborate with the graph of this function.
5 out of 20 like Star Wars so what value (x) should like Star Wars out of 200. Set up a proportion comparing the two.
x= # of people in 7th gr who like Star Wars
5/20= x/200
cross multiply
(5*200)= (20*x)
1000= 20x
divide both sides by 20
50= x
ANSWER: 50 people in the 7th grade should like Star Wars.
Hope this helps! :)
To find the unit rate for 5 you would do price/amount
So 5.75/40=.14375 this rounds down to .14
Therefore the correct answer would be B
For 6 the unit rate is the same, meaning you would have to do price/amount, so 2.99/8=.37375 which rounds to .37
So the correct answer is B
Answer: La respuesta es cada 132 clientes
Lo que hice fue poner la parte de 33 y 44 sumándose entre si:
33+33=66+33=99+33=132 etc
44+44=88+44=132 etc
Y si te diste cuenta concuerdan los dos en 132
Espero que te sirva
Okay so if
4cm:9ft
Than
8cm:18ft
2cm:4.5ft
1cm:2.25ft
Okay so
1•11=11
2.25•11=24.75
The answer is 24.75ft
