//Add 6 to both sides:
//Multiply by -1 on both sides:
Multiply by 3 on both sides:
Divide by 4 on both sides:

Answer: x = 15 (Answer C)-----------------------------------------
Answer:
1.15
Step-by-step explanation:
tan θ=−4/7, and 270°<θ<360°
θ is in 4th quadrant
sec θ = 8.06 / 7 = 1.15
Answer:
answer below
Step-by-step explanation:
when you double the dimension of a rectangular prism you create a very similar one with a scale factor of 2. the surface area will increase and the scale factor will be (2^2 = 4) and volume will be (2^3=8) for the cubes of the scale
Y = 4x -9
y = x-3
Replace the "y" in above equation by x-3
x - 3 = 4x - 9
-3x = -6
x = 2
Then replace x = 2 to the beneth
y = 2 - 3 = -1

<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
An independent variable is a variable that does not depends on other variable while a dependent variable is a variable that depends on other variable.
Let a represent the amount invested at interest of 10% and b represent the amount invested at 8%, hence:
a + b = 155000 (1)
Also:
0.1a + 0.08b = 14100 (2)
From both equations:
a = 85000, b = 70000
