2. 3/4
3. y= 1000(0.75)^x
Step-by-step explanation:
According to the information depicted on the graph:
Vertical intercept = 1000This is the initial Value of acetaminophen in the body just after taking the normal dose ; At time, t = 0Fraction left after 1 hour = 0.75Amount after t hours = [tex]y(t) = 1000(0.75)^{t}[/tex]The vertical intercept is the value of the y - intercept, where the line crosses the y - axis. ; vertical intercept = 1000
The y - intercept is the amount of the drug in the body 0 minutes after taking it.
Fraction of drug left after one hour :
t(1) ÷ t(0) = 750 / 1000 = 3/4 = 0.75Amount of medicine left after t hours :
Initial amount(rate of decrease)^time[tex]y(t) = 1000(0.75)^{t}[/tex]
Hence, the function which models the graph is [tex]y(t) = 1000(0.75)^{t}[/tex]

Which is the graph of the linear inequality y < 3x + 1? On a coordinate plane, a solid straight line has a positive slope and goes through (negative 1, negative 2) and (0, 1). Everything to the left of the line is shaded. On a coordinate plane, a solid straight line has a positive slope and goes through (negative 1, negative 2) and (0, 1). Everything to the right of the line is shaded. On a coordinate plane, a dashed straight line has a positive slope and goes through (negative 1, negative 2) and (0, 1). Everything to the left of the line is shaded. On a coordinate plane, a dashed straight line has a positive slope and goes through (negative 1, negative 2) and (0, 1). Everything to the right of the line is shaded.
For this case we have the following inequality: y < 3x + 1 < br/ >
What we must do is to evaluate a point of the Cartesian plane and verify if it is in the shaded region.
The shaded region represents the solution of the system of equations.
For the point (0, 0) we have:
0 < 3(0) + 1 < br / >
0 < 0 + 1 < br / >
0 < 1 < br / >
Therefore, the point (0, 0) is in the shaded region because it satisfies the inequality.
Then, the points that are on the line, are not part of the solution because the sign is of less strict.

Which digit(s) make the solution of the equations the whole number? 5x-496=1.34...
Answer:
x≈ 100
Step-by-step explanation:
Given the equation
5x-496=1.34...
We are to find the value of x to the nearest whole number
Add 496 to both sides
5x-496+496 = 1.34+496
5x = 497.34
x = 497.34/5
x = 99.468
x ≈ 100
Hence the value of x to nearest whole number is 100

Negative one-fifth of a number, increased
by 3, is at most 1.
The number x ≤ 10 for the inequality (-1/5)x + 3 ≤ 1.
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal = ≤
Greater than and equal = ≥
We have,
Negative one-fifth of the number, increased
by 3, is at most 1.
Number = x
This can be written as,
(-1/5)x + 3 ≤ 1
Solve for x.
(-1/5)x + 3 ≤ 1
(-1/5)x ≤ 1 - 3
(-1/5)x ≤ -2
x ≤ -2 x (-5/1)
x ≤ 10
Thus,
The number is less than or equal to 10.

Write the equation of the line given the points (2,0) and (3.-1)
Answer:
y = -1x + 2
Step-by-step explanation:
We need to find y = mx + b
Use the following equation
[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Plug in the values
[tex]\frac{-1-0}{3-2}[/tex] = [tex]\frac{-1}{1} = -1[/tex]
We have found the slope(m) which is -1
We have to find y-int b
Plug in any given x,y into the slope formula
-1 = -1(3) + b
-1 = -3 + b
2 = b
At last the formula is
y = -1x + 2

what is the answer to -4(2d+3)+2(-d+4)?
Answer:
-10d-4
Step-by-step explanation:
Well, you're in luck because I LOVE distributive property!!!
-4(2d+3) Multiply -4 by 2d to get -8d, and multiply -4 by 3 for -12, so the result would be -8d-12!
Then, 2(-d+4) and therefore 2 times -d (you can just say -1d) to get -2d and 2*4 would be 8 to make -2d+8!
Now you combine them: -8d-12+-2d+8
Combine like terms!
-10d-4 would be your answer.
