Answer: A.Subtract 9 from both sides

Step-by-step explanation:

Answer A: Subtract 9 from both sides

Explanation: You want to solve the x from this equation, then the first thing is to put the number that has no valiable x to the other sides, so in this equations, we want to move 9 to the right side, so we subtract 9 from both sides.

Y=-3x + 10<br> y = -2x + 6<br> Substitution method
Nutka1998 [239]

Answer:

x=4 and y=−2

Step-by-step explanation:

y=−3x+10;y=−2x+6

Step: Solve y=−3x+10for y:

Step: Substitute−3x+10foryiny=−2x+6:

y=−2x+6

−3x+10=−2x+6

−3x+10+2x=−2x+6+2x(Add 2x to both sides)

−x+10=6

−x+10+−10=6+−10(Add -10 to both sides)

−x=−4

-x/-1 = -4/-1 (Divide both sides by -1)

x=4

Step: Substitute4forxiny=−3x+10:

y=−3x+10

y=(−3)(4)+10

y=−2(Simplify both sides of the equation)

HELP ME PLEASE!<br><br> In triangle FGH, GH=1, FG=12, and GH=sq. root of 145
topjm [15]

Answer:

B&C: tan F=0.0833 & tan H=12.0000

Step-by-step explanation:

The tangent relationship is always opposite/adjacent.

When F is the reference angle, side GH (1) is the opposite side and side FG (12) is the adjacent.

1/12 is 0.0833

When H is the reference angle, FG (12) is the opposite and GH (1) is the adjacent.

12/1 is 12.
