Answer: First option is correct.
Step-by-step explanation:
Since we have given that
We need to find the value of the function .
As we have given that x= - 1
so, we substitute the value of x in y :
So, the value of the function is -5.
Hence, First option is correct.
Answer:
B
Step-by-step explanation:
Not A cause the ratios are different, as the first ratio is -1/3 and the rest are 1/3
B is correct cause the ratio is 1/3 and the first term is 1
Not C cause the ratio is not 1/3
Not D cause the ratio is 3
Have a nice day! :)

x=4/7
Step-by-step explanation:
get x alone.
1st get 3 on the other side of the = sign by using the opposite sign. the opposite of addition is subtraction
-5x+3=2x-1
-3 -3
-5x=2x-1-3
-5x=2x-4
now we get the xs together. the opposite of addition( the 2 is positive) is subtraction
-5x=2x-4
-2x -2x
-7x=-4
now let's get the -7 out of here. -7 is multiplying by x. the opposite of multiplication is division.
<u>-7x</u><u> </u>= <u>-</u><u>4</u>
-7. -7
x=-4/-7
negative divided by a negative is a positive
x=4/7
Answer:
f(x) = -5 if -5 <= x <= -3
f(x) = -2 if -3 < x <= 2
f(x) = 5 if 2 < x <= 6
Step-by-step explanation:
This is a simple piece wise function. Notice there are three lines or "solutions" for y-values over a range of x-values. Also notice there are filled in and not filled in circles. If the circle is not filled in, then it is not a solution. If it is, then it is a solution.
So for this, -5 is the solution if the range of x is from -5 through -3 inclusive since it has filled in circles.
-2 is a solution if the range of x is from -3 exclusive through 2 inclusive since at -3 it's open circle and 2 is filled.
5 is a solution if the range of x is from 2 exclusive through 6 inclusive since 2 it's open circle and 6 is filled.
To right that in notation simply
f(x) = -5 if -5 <= x <= -3
f(x) = -2 if -3 < x <= 2
f(x) = 5 if 2 < x <= 6
