Answer:
I think it should be x+4
Step-by-step explanation:
because if u r finding for the overall segment we will add the x units with the four units.
Answer:
The combined mean can be calculated by plugging in our numbers into the formula given: [(57*82)+(23*63)/(57+23)]=76.5
Answer: (x,y)=(-22/69 , 2/23)
Y=6x+2
3x+12y=6x+2
Simplify the expression
-6x+y=2
-3x+12y=2
Multiply both sides of the equation by
-6x+y=2
6x-24y=-4
eliminate at least one variable by adding the equation
-23y=-2
Divide both sides
y=2/23
Substitute the value of y
-6x +2/23 =2
Solve the equation
x=-22/69
The possible solution of the system is the ordered pair
(x,y)=(-22/69, 2/23)
Check the solution
2/23=3x(-22/69)+12x 2/23=6x(-22/69)+2
Simplify
2/23=2/23=2/23
The ordered pair is a solution
Solution
(x,y)=(-22/69 , 2/23)
Answer:
-3x^3+74x-5
Step-by-step explanation:
(x+5)(-3x^2+15x-1)
-3x^3+15x^2-x-15x^2+75x-5
-3x^3+15x^2-15x^2+75x-x-5
-3x^3+74x-5
<h3><u>The value of x is equal to 8.</u></h3>
3(x + 1) = 19 + x
<em><u>Distributive property.</u></em>
3x + 3 = 19 + x
<em><u>Subtract x from both sides.</u></em>
2x + 3 = 19
<em><u>Subtract 3 from both sides.</u></em>
2x = 16
<em><u>Divide both sides by 2.</u></em>
x = 8
