Answer:
4
Step-by-step explanation:
The mean of 2x and 12 is (2x+12)/2, so we get the equation:
(2x+12)/2 = 10 =>
x+6=10
x = 10-6 = 4
* Your question states four numbers, but you write only two... the answer could be wrong because of that.
Answer:
x=2
Step-by-step explanation:
hope this helps
not sure if im right <3
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
<h3>Steps</h3>
3 60/79
•Finding the top part of the fraction
#Firstt times 79 with 3
79× 3 = 237
#Then, u plus it with 60
237 + 60 = 297
•Bottom part
#The bottom part of the fraction stay the same so,
297/79

Answer:
Yes, the following equation is a quadratic function in vertex form
Step-by-step explanation:
we know that
The <u>quadratic function</u> of the vertical parabola into <u>vertex form</u> is equal to
where
(h,k) is the vertex of the parabola
If the <u>coefficient</u> a is > 0 ----> the parabola open upward (vertex is a minimum)
If the coefficient a is < 0 ----> the parabola open downward (vertex is a maximum)
in this problem we have
The <u>squared term</u> contain the x-coordinate of the vertex
The <u>constant term</u> is the y-coordinate of the vertex
The vertex is the point (2,6)
The coefficient is equal to
----> open upward (vertex is a minimum)
