Answer:
if ab= ac and bc= 9 then ba=ac so there for b and a are equivalent so ac=9
Step-by-step explanation:
If the current value of the baseball car is 50 times its original value, its original value will be its current value divided by 50.
Let
represent the current value of the baseball card. We know form our problem that $62 is 50 times the original value,
, of the baseball card, so translating this statement to an equation we get:
We can conclude that the original value of the baseball card was
$1.24.
Answer:
x = 3 ± √5
Step-by-step explanation:
The expression (x - 3)² = 5 doesn't need completing the square to solve (this is the step after you finish completing the square):
Step 1: Square root both sides
x - 3 = ±√5
Step 2: Add 3 to both sides
x = 3 ± √5 = 0.76392, 5.23607
Answer:
x - 5y = 5
Step-by-step explanation:
Let's represent the equation of the graph in slope-intercept form, y = mx + b.
We'd need to find slope (m) and y-intercept (b) of the graph.
Slope (m) = ∆y/∆x
Using two points on the line, (0, -1) and (5, 0),
Slope (m) = (0 - (-1)) / (5 - 0) = 1/5
m = ⅕
y-intercept (b) is the point on the y-axis where the line intercepts the y-axis = -1
Therefore, b = -1
To write the equation, substitute m = ⅕ and b = -1 into y = mx + b
Thus:
y = ⅕(x) + (-1)
y = ⅕(x) - 1
Rewrite in standard form:
-⅕x + y = -1
Multiply both sides by -5
-⅕x*-5 + y*-5 = -1*-5
x - 5y = 5
