Hello :
the solution is : <span>(3, -1)
put x= 3 and y = -1
you have : 3-(-1) = 4 and 3+(-1) = 2 ..... right</span>
Answer:
a. 6
b. 9
c. 4
Step-by-step explanation:
a.
Range = greatest - smallest
Range = 85 - 79
Range = 6
b.
b > 81
82, 83, 84...
3 82s
4 83s
2 85s
3 + 4 + 2 = 9
c.
b = 83
4 83s
4
Answer:
(2,-2)
Step-by-step explanation:
The first step is to substitute y in the first equation with the right side of the second equation because they both equal to y.
-3x+4 = 4x-10
-3x-4x+4-4 = 4x-4x-10-4
-7x = -14
-7x/-7 = -14/-7
x = 2
Plugin 2 for x for either equation to solve for y, I'll be using the second equation, but either one is fine.
y = 4(2)-10
y = 8-10
y = -2
Plugin x = 2 and y = -2 into (x,y), and you get (2,-2)
The answer is 6t^2+2.5x^2-0.5t-5.4
