Answer:
Option 2 ( 1,-10)
Step-by-step explanation:
The two equations are y = -x²-5x-4 -----(1)
and y = -x²+9x-18-------(2)
To get the solution of these lines we will substitute the value of y form equation 1 to 2.
- x² - 5x -4 = -x²+9x-18
Now by collecting similar terms on each side.
-x² -5x + x²-9x = -18 + 4
-14x = -14
14x = 14
x = 1
By putting the value of x in equation 1.
y = -1 - 5 - 4 = -10
So the solution is (1, -10)
Therefore Option 2 is the correct answer.
Given:
The expression is:
To find:
The value of the given expression by using the long division method.
Solution:
We have,
Here, dividend is 6 and divisor is 8.
Since 6<8, therefore we will use the decimal in dividend and quotient as shown below:
(After subtraction)
(After subtraction)
Therefore, the value of the given expression is 0.75.
Answer:
108
Step-by-step explanation:
It is a geometric sequence, so you're always multiplying or dividing by the same amount.
Here, you're multiplying each term by 3 to get the next one.
So, 36*3 = 108
You can then check if this answer is correct by dividing the next term (324) by 3 to see if you get 108.
324/3 = 108
Therefore, the answer is 108.
Answer:
y=-x-4
Step-by-step explanation:
You can write the equations in point-slope form first.
1) y+3=-(x+1)
2) Then you can convert it into slope intercept form
3) y=-x-1-3
4) y=-x-4
