What you would do is make the equation:
91=X+(X-13)
Then, you would solve for X and once you find X, you would subtract 13 from it.
The answers should be 52 and 39.
You reflect point A over the x-axis, double the distance from point a to the x-axis, then give the coordinates.
ex/ point A to the x-axis: 6, reflection: 12. coordinates (-6, 5)
The answer to your question 29 is E 935,00. The way how I got this answer by multiplying 55 and 17,000 and by that the is E. For question 30 the answer is H. The way how I got this answer is by knowing twice means 2 times so by that H was the only one with 15+2n so by that I knew that was the answer.
Hope this helps:)
Step-by-step explanation:
16^3-8^2=4096-512=3584
Answer:
Therefore the solution is = k{-7,5,1} where k ∈R
Step-by-step explanation:
Given that,
f₁(x) =x
f₂(x)= x²
f₃(x)= 7x - 5x²
Also,
g(x) = c₁f₁(x)+c₂f₂(x)+c₃f₃(x)
Putting the values of f₁(x), f₂(x) and f₃(x).
g(x) = c₁.x+c₂x²+c₃(7x-5x²)
Given condition that g(x)= 0
∴ c₁.x+c₂x²+c₃(7x-5x²)=0
⇒(c₁+7c₃)x +(c₂-5c₃)x² = 0
Comparing the coefficients of x and x²
∴c₁+7c₃=0 and c₂-5c₃ =0
Let c₃= k [k∈R]
Then c₁ = -7k and c₂=5k
Therefore the solution is = { c₁,c₂,c₃}
= {-7k, 5k, k}
=k{-7,5,1}
