Answer:
6root2 × 6root2
you have to use pythagoras
a²+b²=c²
c=12
12²=144
a²+b²=144
but it is a square so I'll just change a and b to x because it shows they are equal
x²+x²=144
2x²=144
x²=72
x=6root2
The equation can be split into two equations:
y = log 6x
y = log 2(x + 4)
which is the system of equations that Omar can use to graph the single equation. The equations are logarithmic equations. They can be plotted directly into the coordinate system, use a logarithmic scale coordinate system, or linearize the equations before plotting.
Answer:
-20c - 8 = -8
Step-by-step explanation:
Solve for c.
Set up an equation: -5c - 2 = -2
Add 2 to both sides: -5c = 0
Divide both sides by -5: c = 0
Plug the value of c into the expression: -20(0) - 8
Multiply: 0 - 8
Subtract: -8
Answer: $30
Step-by-step explanation:
Starting with the original formula, you can solve for the cost of the shirt.
First, convert the percentage to a decimal - 15% = .15, and then plug it into the formula:
.15x = $4.50
In order so solve this you need to divide both sides by .15:
X = $30
