What are x,y, and z if x+y+4z=5, -2x+2z, 3x+y+2z=-1, i am desperate

1 answer:

6 0

Answer:

how I learned it in school was that the variable had to always equal something, so you would have to put on the side or where ever x=(a number) and also you multiply those numbers cause no sign would mean multiply (I'm so sorry if it's not write though, I hope I could help you a little)

Answer:

$\textsf{C)}\quad g(x)=\dfrac{1}{2}(x-8)^2-8$

Vertex = (8, -8)

Step-by-step explanation:

Standard form: $y=ax^2+bx+c$

Vertex form: $y=a(x-h)^2+k$

where (h, k) is the vertex

Intercept form: $y=a(x-p)(x-q)$

where p and q are the x-intercepts

Therefore, the form that most quickly reveals the vertex is

$g(x)=\dfrac{1}{2}(x-8)^2-8$

The vertex is (8, -8)

John bought 2.5 kg of corn flour. He used 500g of it to make bread. What percentage of corn flour was left?

34kurt

Answer:

75%

Step-by-step explanation:

2.5 kilograms=2500 grams

2500-500=2000g to find the percent you devide 500/2500 then you get the percentage that was taken away so to find the percentage that was left you minus the 25 percent from 100 which gives you the answer which is 75%
