5(4x - 10) + 10x = 4(2x - 3) + 2(x - 4)
20x - 50 + 10x = 8x - 12 + 2x - 8
30x - 50 = 10x - 20
30x - 10x = -20 + 50
20x = 30
x = 3/2 <==
R=7s/3+k/3
Hope this helps!
Answer:
Both functions have one x-intercept each.
Step-by-step explanation:
The first function is
![f(t )= {t}^{2}](https://tex.z-dn.net/?f=f%28t%20%29%3D%20%20%7Bt%7D%5E%7B2%7D%20)
This is a parabola with vertices at the origin and has one x-intercept at t=0.
The transformed function is
![g(t) = {(t + 3)}^{2}](https://tex.z-dn.net/?f=g%28t%29%20%3D%20%20%7B%28t%20%2B%203%29%7D%5E%7B2%7D%20)
The function g(t) is obtained by shifting the graph of f(t) to the left by 3 units.
This graph also has one x-intercept at x=-3.
Therefore both functions has the same number of x-intercepts
Answer: First option.
Step-by-step explanation:
You know that the product obtained by multiplying a binomial and a trinomial is:
![x^3+3x^2-x+2x^2+6x-2](https://tex.z-dn.net/?f=x%5E3%2B3x%5E2-x%2B2x%5E2%2B6x-2)
Then, in order to simplify this product, it is necessary to add the like terms.
Therefore, the expression that is equivalent to this product after it has been fully simplified is:
![=x^3+(3x^2+2x^2)+(6x-x)-2\\\\=x^3+5x^2+5x-2](https://tex.z-dn.net/?f=%3Dx%5E3%2B%283x%5E2%2B2x%5E2%29%2B%286x-x%29-2%5C%5C%5C%5C%3Dx%5E3%2B5x%5E2%2B5x-2)
You can observe that this matches with the first option.
Answer:
16
Step-by-step explanation:
because 7 times 4 is 28
4 times 4 is 16.
also it says 1/4 and yeah the little box is 1/4 of the big one so that is your answer <3 :]
