Answer:
$14.24
Step-by-step explanation:
9.89+1.99=$11.88
11.88*1.07=12.71
12.71*1.12=$14.24
Hope this helps!
With these types of probe lens with no coefficient for x, all you have to do is find two number that multiply to be 12, and those same two numbers must add to be 7.
Answer: (x+3)(x+4) because 3 and 4 multiply to be 12 as well as add to be 7.
Slope is the change in the y value over the change in the x value. The y value goes from 4 to -3. The change would be -7. X goes from 0 to 2, so the x change is 2. The slope is then (-7/2), or answer c
Answer:
To find to polynomial from zeros.
Find the factors. If it is a positive zero, the factor will be (x- zero) If it is a negative zero if is (x+zero)
Multiply the factors together.
Zeros of -4, -2, 5 would be:
Find the factors: (x+4)(x+2)(x-5)
Multiply the factors together: Will start out with FOIL for (x+4)(x+2) = x2+2x+4x+8 Combine like terms. Then multiply by the last factor
(x2+6x+8)(x-5) using the distributive property
x3+6x2+8x-5x2-30x-40 Combine like terms
x3+x2-22x-40
For the next one, the factors are a bit more complicated because of the radical. With a radical, you will also have to have a factor with the conjugate (Same term opposite sign)
4, 6, negative square root of 7
Factors would be: (x-4)(x-6)(x-√7)(x+√7) You can FOIL the first 2 factors and the last 2, then multiply them together using the distributive property.
