Answer:
from June to July
Step-by-step explanation:
the biggest change was $70
Answer:
14 and 16
Step-by-step explanation:
They are the ONLY consecutive even numbers
And also
x and (x+2)
x(x+2)=224 ( product of a number and the consecutive of that number)
x ²+ 2x-224=0
(x+16)(x-14) =0
x=-16 or 14
In this case 14 and (14+2) 14 and 16
The integers are either 14 and 16 or -14 and -16.
Answer:
i don't know but I think question 1 is 64
Given:
The given function is:
To find:
The range of the given function.
Solution:
We have,
It is a quadratic function because the highest power of the variable x is 2.
Here, the leading coefficient is -32 which is negative. So, the graph of the given function is a downward parabola.
If a quadratic function is 
, then the vertex of the quadratic function is:
In the given function, 
.
The value of the given function at 
is:
The vertex of the given downward parabola is 
. It means the maximum value of the function is . So,
![Range=\left(-\infty, \dfrac{2121}{32}\right ]](https://tex.z-dn.net/?f=Range%3D%5Cleft%28-%5Cinfty%2C%20%5Cdfrac%7B2121%7D%7B32%7D%5Cright%20%5D)
Therefore, the range of the given function is ![\left (-\infty, \dfrac{2121}{32}\right ]](https://tex.z-dn.net/?f=%5Cleft%20%28-%5Cinfty%2C%20%5Cdfrac%7B2121%7D%7B32%7D%5Cright%20%5D)
.
Answer:
(2, 0 )
Step-by-step explanation:
Given the 2 equations
5x - 2y = 10 → (1)
x + 4y = 2 → (2)
Multiplying (1) by 2 and adding to (2) will eliminate the y- term
10x - 4y = 20 → (3)
Add (2) and (3) term by term to eliminate y
11x + 0 = 22
11x = 22 ( divide both sides by 11 )
x = 2
Substitute x = 2 into either of the 2 equations and solve for y
Substituting into (1)
5(2) - 2y = 10
10 - 2y = 10 ( subtract 10 from both sides )
- 2y = 0, so
y = 0
solution is (2, 0 )
