Answer:
Step-by-step explanation:
The straight line equation is:
y = m*x + b Where m is the slope of the line and b the intercept with y-axis, in our case y is the depth of the tank and x (time in lapsus of 3 hours).
The slope m = ( y₂ - y₁ ) / (x₂ - x₁)
We have point A ( 3 , 8 ) and point B ( 6 , 7 )
m = ( 6 - 3 ) / (7 - 8 ) m = -3
We see that each 3 hours time-depth decreases 1 in.
Then to find the depth at the beginning of x-axis
At noon 12 tank was 9 inches, three hours before at 9 in the morning the depth was 10 inches and:
9 in the morning 10
6 in the morning 11
3 in the midnight 12
12 in the night 13
Then 13 is the intercept with y-axis
then the equation is:
h = - 3*x + 13
Note x is time in lapsus of 3 hours

Which expression is equivalent to the given expression?
(-6ab)2
Answer:
B. 36a^2b^2
Step-by-step explanation:
1. Apply exponent rule: (-a)^n = a^n, if n is even
(-6ab)^2 = (6ab)^2
(6ab)^2
2. Apply exponent rule: (a × b)^n = a^nb^n
(6ab)^2 = 6^2a^2b^2
6^2a^2b^2
3. 6^2 = 36
36a^2b^2
In other words, your answer is B.
The answer is Option B)
What are like and unlike terms in an expression?In Algebra, the like terms are defined as the terms that contain the same variable which is raised to the same power.

Explain:
i looked it up
Answer:
4 and 1/6 yards
Step-by-step explanation:
There are 36 inches in each yard since there are 3 feet in a yard and 12 inches in a foot. if you divide 150 inches by 36 inches you get 4 yards with a remainder of 6 inches which is 1/6th of a yard

A new car is purchased for $32,500. The car depreciates every year ata
rate of 14%. Write an exponential function that represents that situation
Answer:
[tex]y=32500(0.86)^{x}[/tex]
Step-by-step explanation:
General exponentially depreciating function is given as
[tex]y= a(1-b)^{x}[/tex]------------(1)
Where a is initial value, b is percent depreciation/unit time and x is time
Here
[tex]a=32,500 \ \ \ b=0.14 \ \ \ and \ \ x \ is \ time \ in \ years[/tex]
Substituting above values in equation (1)
[tex]y=32500(0.86)^{x}[/tex]
At x=0
[tex]y=32500(0.86)^{0}\\y=32500[/tex]
At x=1
[tex]y=32500(0.86)^{1} \\y=27950[/tex]

Details: Cargo ship can carry 21,600 tons Cars weigh 3.6 tons each Trucks weigh 7.5 tons each y = number of cars x= number of trucks Your equation was 3.6y + 7.5x = 21600 Find the number of trucks that can be shipped if there are no cars.
Given:
The equation is
[tex]3.6y+7.5x=21600[/tex]
where, y is the number of cars and x is the number of trucks shipped.
To find:
The number of trucks that can be shipped if there are no cars.
Solution:
We have,
[tex]3.6y+7.5x=21600[/tex]
If there are no cars in the cargo ship, then y = 0 because y is the number of cars.
Putting y=0 in the given equation, we get
[tex]3.6(0)+7.5x=21600[/tex]
[tex]0+7.5x=21600[/tex]
[tex]7.5x=21600[/tex]
Divide both sides by 7.5.
[tex]x=\dfrac{21600}{7.5}[/tex]
[tex]x=2880[/tex]
x is the number of trucks shipped.
Therefore, the number of trucks that can be shipped if there are no cars is 2880.
Grace is plotting the vertices of a parallelogram on the coordinate graph below. She has plotted the three points shown. Where could she plot the fourth point?
Answer:
6,2
Step-by-step explanation:
The fourth point of the parallelogram will be (-6,1) so option (C) will be correct.
What is a parallelogram?A basic quadrilateral with two sets of parallel sides is known as a parallelogram.
A parallelogram's facing or opposing sides are of equal length, and its opposing angles are of similar size.
There are 4 types of parallelograms, including 3 special types. The four types are parallelograms, squares, rectangles, and rhombuses.
The slope of the green lines and red line should be same for being it a parallelogram.
Slope of green line = (7-2)/(3-1) = 2.5
So the only coordinate is matching the slope 2.5 of red line is (-6,1).
Slope = (6-1)/(-4+6) = 2.5
Hence "The fourth point of the parallelogram will be (-6,1)".

SOMEONE HELP BECAUSE I DONT GET THIS
Answer:
x = 18
m<A = 166°
Step-by-step explanation:
The parallel lines are cut by a transversal, so corresponding angles A and B are congruent.
7x + 40 = 3x + 112
4x = 72
x = 18
m<A = 7x + 40 = 7(18) + 40 = 126 + 40 = 166
7x+40 = 3x+112
x=18
7(18)+40
<A = 166

Use the given similar triangles to find the value of x
I need the answer fast please!!
Answer:
I believe the answer is x=7
Step-by-step explanation:
3x and 4x-1 are corresponding sides and so are 14 and 18.
You cross multiply with the smaller triangle lengths at the top.
3x/(4x-1)= 14/18
Cross multiply to get
18(3x)= 14(4x-1)
54x=56x-14
Subtract 54x on the other side and add 14 to the other (or subtract 56x to the other side)
you get 14=2x and divide 14 by 2 to get x=7
true or false? help please
Answer:
True
Step-by-step explanation:
Parallel lines always have the same slope, so therefore the answer is True
Answer:
True!
Step-by-step explanation:
These equations are parallel, because all equations that are parallel are going to have the same slope, and both of these equations have the same slope! If it was 5/3 and -3/5, then it would be perpindicular, because that is the negative reciprocal! I hope this helps!
