M= J+2 1/2
So J+M would equal there total distance
Answer:
x=1 and y= -4
Step-by-step explanation:
step one: plug -4x into y in thi]e first equation.
2x+5(-4)= -18
step two: solve for x
2x-20= -18
(add 20 to both sides to eliminate -20 on the right)
2x=2
(divide both sides by 2 to get x by its self)
x=1
step 3: now that we found the value for x plug it in to either equation and solve for y
y= -4x
y= -4(1)
y= -4
That is a G major. The hashtag means major and it is located on the in the middle of he top line.
Answer:
Depends on domain of x, could be
-√(y+10)/7; √(y+10)/7 or no solutions
Step-by-step explanation:
You need to solve it for x:
y=7x^2-10
7x^2=y+10
x^2=(y+10)/7
In order for this equation to have an inverse, you need to check the domain of x. There needs to be only one solution for x^2=(y+10)/7 - either positive or negative, depending on the domain.
