Isolate the x. Do the opposite of PEMDAS. Note the equal sign, what you do to one side, you do to the other.
First, subtract 8 from both sides
8 (-8) + 7x = -61 (-8)
7x = -69
Next, isolate the x. Divide 7 from both sides
7x/7 = (-69)/7
x = -69/7
x = ~-9.86 (rounded)
hope this helps
Answer:
The slope of the line passing through the points (-3, 7) and (2, -6) is -13/5.
Step-by-step explanation:
Use the slope formula to find the slope of the line based on two points.
m = y₂ - y₁/x₂ - x₁
Substitute the values
m = -6 - 7/2 - (-3)
Simplify.
m = -13/5
The slope of this line is -13/5.
X+79=98 (subtract 79 to isolate x)
X=19 so it is false
Answer:
It is an imaginary number.
Step-by-step explanation:
The square root of negative one is "i," the imaginary number. This concept is immensely useful in mathematics, as it allows for there to be square roots of negative numbers, which is otherwise not possible using only real numbers.
Any number that includes a negative square root is called an imaginary number. For example, the square root of -9 equals 3i, an imaginary number. When an imaginary number and a real number are combined, for example 2 + 3i, this is called a complex number. Complex numbers have many real world applications, including manipulating sound waves and calculating electrical currents.
