Answer:
To solve this we need to form 2 equations with only 2 variables.
x+4y-5z=-7
2x+y+5z=8
3x+5y=1
15x+10y+15z=35
6x+3y+15z=24
9x+7y=11
Now we need to use these to find x and y
9x+15y=3
9x+7y=11
8y=-8
y=-1
Therefore:
x=2
From this we can find that:
2(2)-1+5z=8
Therefore z=1
The answer is x=2, y=-1, z=1
Answer:
Option (3)
Step-by-step explanation:
If binomial (x - 6) and trinomial (-2x² + x + 9) are the factors of a polynomial then their multiplication will be equal to the polynomial.
(x - 6)(-2x² + x + 9) = x(-2x² + x + 9) - 6(-2x² + x + 9)
= -2x³ + x² + 9x + 12x² - 6x - 54
= -2x³ + 13x² + 3x - 54
Therefore, Option (3) will be the correct option.
To find the length of the light pole you'll have to use the sine ratio.
sin 30 = x/43
43 (sin 30) = x
21.5 = x
Hope this helps :)
Answer is A and B. Solutions are where the two graphs cross, so you just need to find those coordinates, which are (-5,-13) and (2,-6).
Answer:
The interval notation for the domain is ![[\frac{23}{3},\infty ]](https://tex.z-dn.net/?f=%5B%5Cfrac%7B23%7D%7B3%7D%2C%5Cinfty%20%20%5D)
.
Step-by-step explanation:
Consider the provided information.
It is given that 
We need to find the value of 
.
Put the value of g(x) in .
....(1)
Now, put x=x-7 in 
From equation 1.
The domain of the function is the set of input values for which a function is defined.
Here, the value of 
should be greater or equal to 0 as the square root of a negative number is not real.
Domain= 
The value of x is all real number greater than 
.
Hence, the interval notation for the domain is .
