Answer:
AAAAAAAAAAAA answer is A
Step-by-step explanation:
I hope this helps you
1.k^2+5k-6=0
a=1
b=5
c= -6
disctirminant =b^2-4ac
disctirminant =5^2-4.1. (-6)
disctirminant =49
x1= -(5)+ square root of 49/2.1
x1=-5+7/2
x1=1
x2= -5- square root of 49/2.1
x2= -5-7/2
x2= -6
Answer:
The vertical line test is a visual test used to determine whether or not a graph is a function. To perform this test, simply draw a straight vertical line multiple times on different parts of the graph.
If a vertical line intersects with the graph at one point, then it's a function.
If a vertical line intersects with the graph at multiple points, then it's not a function.
Examples:
Step-by-step explanation:
x = number of cans.
790 total cans and bottles.
790 - x = number of bottles.
y = weight of the cans and bottles in ounces.
y = 14x + 70×(790 - x) = 14x + 55300 - 70x = 55300 - 56x
Let the prices of a pack of potato chips and can of coke be x and y respectively
3x+2y=50-9
3x+2y=41........... (1)
4x+5y=50+21
4x+5y=71............(2)
Multiply (1) with 4 and (2) with3
12x+8y=164
12x+15y=213
On subtracting above eqs. we get
7y= 49
y=7
Putting value of y in (2)
4x+5(7)=71
4x+35=71
4x=36
x=9
x=$9
y=$7
