Answer:
A
Step-by-step explanation:
Joint variation is given by:
[tex]y=kxz[/tex]
Where k is some constant.
We are given that y = 360 when x = 4 and z = 10. Therefore:
[tex]360=k(4)(10)[/tex]
Solving for k:
[tex]40k=360\Rightarrow k=9[/tex]
Therefore, our equation is:
[tex]y=9xz[/tex]
Then when x = 5 and z = 12:
[tex]y=9(5)(12)=540[/tex]
The answer is A.
Help me please answer thanks

y = 5x - 6&y= -4x + 3
Use the Equal Values Method to solve for x and y
Answer: x = 1 and y = -1
Step-by-step explanation:
Since both equations are equal to y, that means the equations are both equal to each other
5x - 6 = -4x + 3
Solve for x how you would traditionally do it with any other one-variable equation
9x = 9
x = 1
Plug the now known x value into either equation and you will get your y value.
5(1) - 6 = -1
-4(1) + 3 = -1
In a right triangle ABC, C is the right angle. What does sinB equal?
A)
cos (90°-B)
B)
sin (90°-B)
C)
cos B
D)
Both A and C are correct
9514 1404 393
Answer:
A) cos (90°-B)
Step-by-step explanation:
The sine of an angle is equal to the cosine of its complement.
sin(B) = cos(90° -B)

pls helpppp asapppp with the question above
Answer:
the answer should be B
Step-by-step explanation:
i do apologize if its wrong im like 99.9% sure it correct
Answer:
0
Step-by-step explanation:
4(m+2) = -4(m-2)
by dividing over 4 :
m+2 = -1(m-2)
= m+2 = -m+2
by subtracting 2 :
m = -m
by adding "m" :
2m = 0
So
m = 0
I hope that the explanation is clear for you.

20y-10x=5 in slope intercept form can you explain the steps
Given:
The equation is
[tex]20y-10x+5[/tex]
To find:
The slope intercept form of the given equation.
Solution:
The slope intercept form of a linear equation is
[tex]y=mx+b[/tex]
Where, m is slope and b is the y-intercept.
We have,
[tex]20y-10x=5[/tex]
We need to isolate y. Add 10x on both sides.
[tex]20y-10x+10x=5+10x[/tex]
[tex]20y=5+10x[/tex]
Divide both sides by 20.
[tex]\dfrac{20y}{20}=\dfrac{5+10x}{20}[/tex]
[tex]y=\dfrac{5}{20}+\dfrac{10x}{20}[/tex]
[tex]y=\dfrac{1}{4}+\dfrac{x}{2}[/tex]
[tex]y=\dfrac{1}{2}x+\dfrac{1}{4}[/tex]
Therefore, the slope intercept form of the given equation is [tex]y=\dfrac{1}{2}x+\dfrac{1}{4}[/tex].
can someone pls help me with this i don’t know what i am doing haha..

y =
x +
Answer:
[tex]y = 7x [/tex]
Step-by-step explanation:
To find the slope, which is
[tex] \frac{rise}{run} [/tex]
find how high up the y value goes before it intersects the x line at a specific point. It seems that they intersect at (70,10) which would be 70/10 or 7/1. 7/1 is just 7 so the slope of it is just that, 7. As for finding B, look at where the line starts, of it's above or below 0, then you would add or subtract whatever number it starts at (subtract for negative, add for positive). In this case it seems that the intercept is right at 0 so you would neither add or subtract anything. :)
