The equation of the line in this graph is y = 3/2x + 3.
Explanation:
In slope intercept form equations, the initial value is where everything begins. In this equation, that would be at the point (0,3). From there, because it is going up toward the right side, there is a positive slope. The formula for slope is rise over run, so to get our slope, we have to go up 3 units and over 2 units.
Answer:
The amount invested at 5% was $39,000 and the amount invested at 7% was $11,000
Step-by-step explanation:
we know that
The simple interest formula is equal to
where
I is the Final Interest Value
P is the Principal amount of money to be invested
r is the rate of interest
t is Number of Time Periods
Let
x-----> the amount invested at 5%
50,000-x -----> the amount invested at 7%
so
substitute in the formula above
solve for x
therefore
The amount invested at 5% was $39,000 and the amount invested at 7% was $11,000
Answer:
Step-by-step explanation:
Point-slope equation for line of slope m that passes through (x₀,y₀):
y-y₀ = m(x-x₀)
In your case, m=5 and (x₀,y₀)=(1,9):
y-9 = 5(x-1)
Answer:
A negative number squared is a positive number. Squaring is multiplying a number by its self.
Step-by-step explanation:
X^2 = x * x
Squaring something is just multiplying it by its self.
A negative times a negative = a positive
A positive times a positive = a positive
A negative times a positive = a negative
A positive times a negative = a negative
- * - = +
+ * + = +
- * + = -
+ * - = -
Here is how my 6th grade teacher helped me to remember it:
If something bad (-) happens to a bad guy (-), that is good.
If something good (+) happens to a good guy (+), that is good.
If something bad (-) happens to a good guy (+), that is bad.
If something good (+) happens to a bad guy (-), that is bad.
I hope I helped!
