Answer:
11
Step-by-step explanation:
F(-1)= -3 is (-1,-3) and f(2) = 6 is (2,6) where f(x) = y
y=mx + b is the slope-intercept form whereas m equals the slope (rate of change) and b equals the y-intercept (initial amount/what y is when x is 0.)
First, we need to find the slope between the two points (-1,-3) and (2,6). To find the slope we could use one of it's formulas

.
1. (-1,-3)
2. (2,6)

The slope is 3 (

). Thusly, y = 3x + b
To find out the y-intercept, we can reverse the slope. [Note: This

is in

where rise is 'y' and run is 'x'. Reversed would be

]. Take the second ordered pair and use our reversed slope on it until we get 0 for x.
(2, 6) ⇒ (2 - 1, 6 -3) ⇒ (1, 3) ⇒ (0,0)
Y-intercept is 0. Therefore,
y= 3x + 0 [NOTE: y = f(x), so if you want it in function notation form it's just f(x) = 3x + 0.]
Answer:
24/35 and the difference between two fractional numbers with same or equal denominators 5/7 and 2/7.
X2=4(5-1)
x2=4(4)
x2=16
x=4
Check: 4 squared (4 times 4) equals 16. When you square a number, you multiply the number by itself.
Answer:
14%
Step-by-step explanation:
The item dropped from $50 to $43 .
Therefore,
Decrease = $50 - $43
= $7
To get the % decrease, divide the decrease by the initial price and multiply the result by 100%
That’s
$7/$50 x 100%
$0.14 x 100%
= 14%
The price of the item decreased by 14%
