Subtract 89 from -42. k=-131
The initial amount in the account was $200 (y intercept). She adds $32.50 each day to her bank account (slope).
Answer:
<h2>C. infinity many</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line:
m - slope
b - y-intercept
If the equations have the same slopes and the same y-intercepts, then the system of equations has infinitely many solutions.
If the equations have the same slopes and differences of the y-intercepts, then the system of equations has no solution.
If the equations have different slopes, then the system of equations has one solution.
We have
→ m = -6 and b = 3
and
convert to the slope-intercept form:
<em>subtract 30x from both sides</em>
<em>divide both sides by 5</em>
→ m = -6 and b = 3
<em>We have the same slopes and the same y-intercepts.</em>
divide 2 b 3
2 divided by 3 = 0.625
move decimal point 2 places to the right to turn to a percentage
0.625 = 62.5%
Answer:
7^6
Step-by-step explanation:
= 7^(13-7) (bases are the same)
= 7^6
