Solve for a
6a-15=72
Answer:
a=
Step-by-step explanation:
72+15=87
87/6= 14.5
a= 14.5
Answer: 14.5
Step-by-step explanation:
6a - 15 = 72
add 15 on both sides
6a = 87
divide by 6 on both sides
a = 14.5
(SAT Prep) Find the value of X. Plz help me I will give brainliest.
Answer:
Solution given:
a=40°[alternate angle are equal]
again
a+x+20°=180°[sum of angle linear pair is supplementary]
substituting value
40°+20°+x=180°
x=180°-60°
x=120°
A basketball is thrown in the air. Part way up, the potential energy is 100 J, and its kinetic energy is 25 J. What is the total mechanical energy of the basketball?
Answer:
125
Step-by-step explanation:
mechanical energy is equal to the sum of kinetic and potential energy
100+25=125

Use math vocabulary to explain why you think this number does not belong in the group. Be sure to write in complete sentences.
Answer:
because like for example the given number are 01 12
23 34
or 12233445566778 and etc.
your situation are 4556 and 3224 because are not ordered pair

Answer:
Scientific notation is just a short hand way of expressing gigantic numbers like 1,300,000 or incredibly small numbers like 0.0000000000045. Also known as exponential form, scientific notation has been one of the oldest mathematical approaches. It is favored by many practicioners. If numbers are too big or too small to be simply calculated, people reffer to scientific notation to handle these circumstances. This method is used by engineers, mathematicians, scientists.
An example of scientific notation is 1.3 ×106 which is just a different way of expressing the standard notation of the number 1,300,000. Standard notation is the normal way of writing numbers.
Step-by-step explanation:
this is the integer or first digit in any Scientific Notation. For example in 1.3 ×106, the mantissa is the "1"

Question 3 of 10
The slope of the line below is 4. Which of the following is the point-siope form
of the line?
A. y- 4 = 4(x-3)
B. y+ 4 = 4(x + 3)
C. y+ 4 = 4(x+3)
Dy-4--4(x-3)
Answer:
The point-slope form of the line is:
[tex]y + 4 = 4(x+3)[/tex]
Hence, option B is correct.
Step-by-step explanation:
We know the point-slope form of the line equation is
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where
m is the slope of the line(x₁, y₁) is the pointGiven
The slope m = 4
From the graph, we can take the point (-3, -4)
So, in our case:
(x₁, y₁) = (-3, -4)
m = 4
now substituting m = 4 and (x₁, y₁) = (-3, -4) in the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y - (-4) = 4(x - (-3))[/tex]
[tex]y + 4 = 4(x+3)[/tex]
Therefore, the point-slope form of the line is:
[tex]y + 4 = 4(x+3)[/tex]
Hence, option B is correct.
The graph of the line is also attached.PLEASE I NEED HELP I ONLY HAVE 3 MINUTES TO SOLVE THIS PLEASE HELP
