Step-by-step explanation:
9(m-3)+3m=7m+43 what is the answer
Answer:
9(m - 3) + 3m = 7m + 43
=>9m - 27 + 3m = 7m + 43
=> 12m - 27 - 7m = 43
=> 5m - 27 = 43
=> 5m = 70
=> m = 70/5 = 14
Answer:
m=14
Step-by-step explanation:
start with your parenthesis and multiply 9 to m-3 which makes that 9m-27+3m=7m+43
add your m together making that 12m-27=7m+43
add 27 to both sides equalling 12m=7m+70
subtract 7m from both sides resulting in 5m=70
divide both sides by 5 equalling m=14

Which represents an even function?
A. y = cos(x)
B. y = sin(x)
C. y = tan(x)
D. y = cot(x)
NVM I DID IT
ANSWER: A
Answer:
A. y=cos(x)
Step-by-step explanation:
I just want the points. im taking the quiz rn.
From the given options, the only even function is the cosine function, so the correct option is A.
Which of the options is an even function?First, an even function is a function with the property:
f(x) = f(-x)
So these functions are symmetrical across the y-axis.
Is ratter easy to remember that the sin function is actually odd, this means that:
sin(-x) = -sin(x).
Then the tangent function (and the cotangent function) are also odd, because:
tan(x) = sin(x)/cos(x).
In the other hand, for the cosine function we have:
cos(-x) = cos(x)
And as shown in the graph below, it is symmetrical across the y-axis.
Then we conclude that the correct option is A.

Find the distance between the points (2,0) and (-4,6)
Answer:
let's see what to do buddy...
Step-by-step explanation:
We have this equation to find the distance between two points :
a = ( 2 , 0 ) and b = ( -4 , 6 )
[tex]distance = \sqrt{ {( \: y(b) - y(a) \: })^{2} + ( \: {x(b) - x(a)} \: )^{2} } \\ [/tex]
Now just need to put the coordinates in the equation :
[tex]distance = \sqrt{ ({6 - 0})^{2} + ({ - 4 - 2})^{2} } \\ distance = \sqrt{ {6}^{2} + ({ - 6})^{2} } = \sqrt{36 + 36} \\ distance = \sqrt{36 \times 2} = 6 \sqrt{2} [/tex]
And we're done.
Thanks for watching buddy good luck.

A swimming pool has a length of 28 feet, a width of 17 feet, and a depth of 6 feet. How much water can the swimming pool hold?
A.
5,712 cubic feet
B.
1,492 cubic feet
C.
2,856 cubic feet
D.
746 cubic feet
Answer: C. 2,856
Step-by-step explanation: The formula for volume is V= lwh (length x width x hight). So you'd do 28 x 17 x 6 = 2,856.

Answer:
-0.4 should be in between 0 and -0.5, however be as close to -0.5 as possible while not being ON -0.5.
3 4/5 should be in between 3 and 4, so you can split 4/5 into 8/10 which are equal to each other. Then you can pretend to split the 3 and 4 gap into 10 equal pieces. After you split the gap, count 8 parts to the left of 3.

Answer:
s = 0.3m
Step-by-step explanation:
Given that s varies directly with m then the equation relating them is
s = km ← k is the constant of variation
To find k use the condition
s = 9 when m = 30
9 = 30k ( divide both sides by 30 )
[tex]\frac{9}{30}[/tex] = k
s = [tex]\frac{9}{30}[/tex] m or
s = 0.3m ← equation of variation
