For each input (number), there is exactly ONE output. So the given table does represent a function.
If <span>f(x)=925x+1000 and x=24, then f(24) = 925(24)+1000 = 23200.</span>
Hi
5x²-x-4 = 0
Δ= (-1)² - 4*5*(-4)
Δ = 1 -4*-20
Δ = 1 +80
Δ = 81
√Δ= 9
as Δ ≥ 0 , so 2 solutions exist in R
S1 is : ( 1+9) /2*5 = 10/10 = 1
s2 = (1 -9)/2*5 = -8/10 = -4*2 /2*5 = -4/5
Corrects answers are A and D
Answer:
6 cm
Step-by-step explanation:
Area of a rectangle = length * width
Here, length and width are 12 cm and 3 cm, so
Area = 12*3 = 36 cm squared
Area of a square = side * side
36 = 6*6
Thus, side = 6 cm
Answer:
Some number divided by 4
Step-by-step explanation:
The y stands for an unknown number, aka some number. The slash indicates division, so it would be some number divided by 4.
Answer:
The distance between two points; the solution is √200 units
Step-by-step explanation:
To determine the distance between two points, get the difference between the y-co-ordinates which is (6)-(-4)=10 units in this case. Consequently obtain the difference between the x-co-ordinates values which in this case is -3-7=-10 units. Thereafter we square these two values, sum them then obtain their square root. That is, square root of (100+100). √200 = 14.14
