The equation y = −3x + 7 represents the amount of water y left in a 7-gallon tub after x minutes.
(PART A)
Where does the graph of the equation intersect the y-axis and the x-axis?
y-axis: (_, _)
x-axis: (_/_, _)
(PART B)
What do these points represent?
At ___ minutes, the tub has ___ gallons of water.
The tub is empty at _/_ minutes.
The amount of water in the tank y after x minutes, y = -3•x + 7, gives;
Part A: The points the graph intersects the y–axis is (0, 7)
The points the graph intersects the x–axis is (7/3, 0)
Part B; At zero minutes, the tub has seven gallons of water.
The tub is empty after 7/3 minutes
How can the amount of water in the tub be evaluated?The given equation that gives the amount of water, y, left after x minutes is presented as follows;
y = -3•x + 7Part A; The location where the graph intersect the y-axis, the y-intercept is found as follows;
At the y-intercept, x = 0, which gives;
y = -3×0 + 7 = 7
The point the equation intersect the y-axis is therefore;
(0, 7)The location where the graph intersect the x-axis, which is the x–intercept is given by the point where y = 0, which gives;
y = -3•x + 7
0 = -3•x + 7
x = 7/3
The point the graph intersects the x-axis is the point;
(7/3, 0)Part B;
The meaning of the points are expressed as follows;
(0, 7), the y-intercept, the point the graph intersects the y–axis, gives the amount of water in the tub at the start of the measurement.
Which gives;
At zero minutes, the tub has seven gallons of water.The point the graph intersects the x–axis, the x–intercept represents the time at which the tub becomes empty.
Which gives;
The tub is empty after 7/3 minutesLearn more about linear equations in mathematics here:

Step-by-step explanation:
(16, 0), (0, 12)
(x₁, y₁) (x₂, y₂)
d = √(x₂ - x₁)² + (y₂ - y₁)²
d = √(0 - 16)² + (12 - 0)²
d = √(-16)² + (12)²
d = √(-16)² + (12)²
d = √256 + 144

Answer:
B) the definition for the direction of an electric field line is the way a positive test charge would move.
The definition for the direction of an electric field line is the way a positive test charge would move. Option B is correct.
What is the charge?When placed in an electromagnetic field, the physical attribute of matter known as electric charge causes it to experience a force. Positive and negative electric charges are the two types of charges that charge carriers, protons, and electrons, frequently carry. The movement of charges produces energy.
here,
Because the definition for the direction of an electric field line is the way a positive test charge moves, the charge on the left is positive and the charge on the right is negative.
Thus, the direction of an electric field line is defined as the movement of a positive test charge. Option B is the right answer.

Higher Order Thinking: Chef Morgan's
restaurant has 24 tables. Fifteen of the
tables each have one flower in a vase.
The remaining tables have 5 flowers in
each vase. How many flowers are there?
Show how you found the answer.
⬇️—Answer—⬇️
60 flowers in Chef Morgan’s Restaurant.
⬇️—Solutions (with-steps)—⬇️
We are given the following information :
1) The restaurant has 24 tables.
2) 15 of those tables have 1 flower in each vase.
3) The remaining have 5 flowers
15 of her tables + her remaining tables = 24 of her total tables.
This means, 15 of her tables have one flower in each vase while she has 9 tables which are remaining containing 5 flowers in their vases.
In mathematics each usually means to multiply something. So,
15 x 1 = 15
9 x 5 = 45
15 + 45 = 60
So, there are 60 flowers in total.
To check our answer:
(15 x 1) + (9x5) = 60

Four brothers have ages that are consecutive even integers. From youngest to oldest, their names are Matt, Pat, Dave, and Dan. If Dan's age is 36 years less than twice Pat's age, then what are the ages of all four brothers?
Answer:
Matt - 38, Pat - 40, Dave - 42 and Dan - 44
Step-by-step explanation:
Lets take Matt's age as x, Pat's age as x + 2, Dave's age as x + 4 and Dan's age as x + 6.
Given, Dan's age is 36 years less than twice Pat's age
Equation:
x+6 = 2(x+2) - 36
= x+6 = 2x + 4 - 36
= x+6 = 2x - 32
= 6+32 = 2x - x
= x = 38
Matt - x = 38
Pat - x+2 = 40
Dave - x+4 = 42
Dan - x+6 = 44
Answer:
Matt = 38, Pat = 40, Dave = 42, Dan = 44
Step-by-step explanation:
Say Matt is x. We already know that Dan's age is 36 less than twice Pat's age so it is written like 2(x + 2) - 36 = x + 6
Simplify to 2x + 4 - 36 = x + 6
Simplify more to x = 38
That means Matt is 38 years old. Since they are consecutive even numbers, then Pat's age is 40, Dave's age is 42, and Dan's age is 44.
