Answer:310
Step-by-step explanation:
so use pemdas
Parenthesis,exponents multiplication, division , addition, and subtraction order
231*5-16+101)/4
first i'm assuming the parenthesis is over the whole thing
that the question should look like (231*5-16+101)/4
first parenthesis, 231*5=1,155
1,155-16=1,139+101= 1,240
1240/4= 310.
Hope this helps!
Answer:
The values of x are x = -2 and x= 1.
Step-by-step explanation:
The given equation -x²+4 = x+2 can be written in the form of two functions as
y = -x²+4 which is a function representing parabola and
y = x+2 which is a straight line.
Now we will solve the given equation to find their points of intersection on graph. Their points of intersections will be the answer.
-x²+4 = x+2
-x²+4-x = x+2-x
-x²-x+4 = 2
-x²-x+4-2 = 2-2
-x²-x+2 = 0
Or x²+x-2=0
Now we will factorize the equation.
x²+2x-x-2=0
x(x+2)-1(x+2) = 0
(x+2)(x-1) = 0
x+2 = 0 ⇒x = -2
x-1 = 0 ⇒x = 1
For x = 1, y will be 3
and for x = -2, y will be 0
Now we can see the graph for the given coordinates (-2,0) and (1,3).
Which set of orderd pairs is a function A.( -6, -4 ), (-4, -2) , ( 0, 0 ), (-4, 2 ) ,( -6, 4) B. ( -2 , 1 ) , (-4, 2) , ( 0, 3)

The answer is D
Step-by-step explanation:
To be a function, you cannot have the same x values.
Answer:
X=7
Step-by-step explanation:
So first add them all up
x-2+2x+x+3=4x+1
4x+1=29
4x=28
x=7
Answer:
$323
Step-by-step explanation:
Hello! First you would need to divide $171 by 9 to see how much money she makes an hour....
$171 / 9 = $19 an hour
Now that you know how much she makes an hour, multiply that amount by 17 to find out how much money she will make if she works for 17 hours.
$19 * 17 = $323
She will make $323 if she works for 17 hrs. :)
Hope this helps!
