Answer:
It would have started to be filled at 10 cm
Step-by-step explanation:
FInd teh difference between 8 and 2 which is 6
Find the difference between 34 and 16 which is 18
Divide 18 by 6 which is 3
Subtract 2(3) = 6 by 16 which is 10
Using the linear system to solve the problem. Then the water level at 0 minutes is 10 cm.
What is the linear system?It is a system of an equation in which the highest power of the variable is always 1. It is a combination of infinite points side by side.
Given
Henry is filling up his fish tank with water at a constant rate.
At 2 minutes the water level is 16 cm.
At 8 minutes the water level is at 34 cm.
We know that the linear equation
[tex]\rm y = mx +c[/tex]
Where
m be the rate of filling water in the tank.
c be the initial water in the tank.
y be the water level of the tank in cm.
x be the time in minutes.
At 2 minutes the water level is 16 cm. Then
[tex]\rm 16 = 2m + c[/tex] ...1
At 8 minutes the water level is at 34 cm. then
[tex]\rm 34 = 8m +c[/tex] ...2
From equations 1 and 2, we have
m = 3, and c = 10
Then the equation will be
[tex]\rm y = 3x + 10[/tex]
For x = 0, then y = 10
Thus, the water level at 0 minutes is 10 cm.

How would you find the quadratic that goes through the point (4,0), the axis of symmetry is x=7, and it also goes through the point (1,5)?
9514 1404 393
Answer:
y = (5/27)(x -7)^2 -5/3
Step-by-step explanation:
Use the given points to find the unknowns in the equation.
If the axis of symmetry is x=7, then the equation can be written in the form ...
y = a(x -7)^2 +b
Filling in the two point values, we have two equations:
0 = a(4 -7)^2 +b ⇒ 9a +b = 0
5 = a(1 -7)^2 +b ⇒ 36a +b = 5
__
Subtracting the first equation from the second, we have ...
(36a +b) -(9a +b) = (5) -(0)
27a = 5
a = 5/27
Substituting that value into the first equation gives ...
9(5/27) +b = 0
5/3 +b = 0
b = -5/3
So, the quadratic can be written in vertex form as ...
y = (5/27)(x -7)^2 -5/3

y = -4x - 12
What is the slope(m) and the y-intercept (b)
Answer:
x=6.0
Step-by-step explanation:
the slope (m) is -4, indicating a downward slope, and the y-intercept (b) is -12,
In the equation y = -4x - 12, the coefficient of x, -4, represents the slope of the line. The slope (m) is the ratio of the vertical change to the horizontal change between any two points on the line. In this case, the slope is -4, indicating that for every unit increase in x, the y-value decreases by 4.
The constant term, -12, represents the y-intercept (b). The y-intercept is the point where the line intersects the y-axis. In this equation, the y-intercept is -12, which means that the line crosses the y-axis at the point (0, -12).
To summarize, the slope (m) is -4, indicating a downward slope, and the y-intercept (b) is -12, representing the point where the line crosses the y-axis.

Given polynomial 2x⁴ + 2x³ - x² - x will be solved as below:-
P = 2x⁴ + 2x³ - x² - x
P = x ( 2x³ + 2x - x - 1 )
P = x ( 2x² [ x + 1 ] -1 ( x + 1 )
P = x ( 2x² - 1 ) ( x + 1 )

The double number line shows that 4 pounds of tomatoes cost $14. Draw tick marks and write labels to show the prices of 1, 2, and 3 pounds of tomatoes.
Answer:
every tick is 3.50
Step-by-step explanation:
14/4=3.5
The price of one, two, and three pounds of tomatoes is $10.5. Each quantity is represented by its own number line in a double number line, with corresponding pairs of values lined up.
How are double number lines created?Equal ratios are represented by two parallel number lines in a double number line diagram. The tick marks are in the same places on both number lines.Despite the fact that the other numbers change frequently, the tick marks labeled with 0 always line up.Diagrams with a double number line can show you how two quantities are related in terms of their ratios.They work best when the quantities have different units. (The unit rate is represented by the number 1) Students can more easily "see" that the same ratio can take many different comparable shapes when using double number line diagrams.Therefore,
Given,
4 pounds of tomatoes cost = $14
We find the prices of 1, 2, and 3 pounds of tomatoes
14/4 = 3.5
So,
1 lb = 3.5
2 lbs = 2× 3.5 = 7
3 lbs= 3 × 3.5 = 10.5
Hence, The price of one, two, and three pounds of tomatoes is $10.5.

What is the equation, in slope-intercept form, of the line that passes through (0, 6) and has a slope of 4 (5 points)
Answer: y=4x+6
Step-by-step explanation: you replace the variables in the equation with the variables in the point given to find b.
Answer:
[tex]y = 4x+6[/tex]
Step-by-step explanation:
Equation of a line
The equation of a line can be written in the form:
[tex]y = mx+b[/tex]
Where m is the slope of the line and b is the y-intercept. We are given the value of m=4, thus the equation becomes:
[tex]y = 4x+b[/tex]
To find the value of b, we use the point (0,6):
[tex]6=4*0+b[/tex]
Solving:
[tex]b=6[/tex]
Thus, the equation in slope-intercept form of the required line is
[tex]\boxed{y = 4x+6}[/tex]

The estimated total cost, y, of a child's toy is partially based on the number of batteries used, x. The cost per battery is $0.50. They toy itself costs $15. Which equation represent the situation?
a
y = 0.50x - 15
b
y = 15x - 0.50
c
y = 15x + 0.50
d
y = 0.50x + 15
Answer:
D: 0.50x+15
Step-by-step explanation:
batteries used(each)- x, so you add the x in front of 0.50 representing multiplication between the #
you are doing total cost so you are doing addition (obvously) then its a plain $15 for the toy itself therefore,
y=0.50x+15 (hope this made sense)
