If she took $20 out of her savings account, given the information, she could easily have no money remaining now. Given this, we'll assume the current value of her account is the minimum it can be. Now you just need to find how many times her withdrawal can factor into the original amount, $250. Therefore, t=250/20= 12.5. Since it's asking for a number of weeks, the answer can't be a decimal, so your final answer is 12 weeks.

The equation of the line with slope -3 and passes through (2,-1) is y = -3x + 5
<u>Solution:</u>
In the question it is given that the line passes through the point (2,-1) with slope (m) = -3. We have to find out the point slope form and slope intercept form of the equation.
We know the point - slope form of an equation is given by
![\left(y-y_{1}\right)=\mathrm{m}\left(x-x_{1}\right)](https://tex.z-dn.net/?f=%5Cleft%28y-y_%7B1%7D%5Cright%29%3D%5Cmathrm%7Bm%7D%5Cleft%28x-x_%7B1%7D%5Cright%29)
![\text { Here } y_{1}=-1 \text { and } x_{1}=2 \text { and the slope } m=-3](https://tex.z-dn.net/?f=%5Ctext%20%7B%20Here%20%7D%20y_%7B1%7D%3D-1%20%5Ctext%20%7B%20and%20%7D%20x_%7B1%7D%3D2%20%5Ctext%20%7B%20and%20the%20slope%20%7D%20m%3D-3)
Substituting the values in the point slope form of the equation we get
(y-(-1)) = -3(x-2)
(y+1) = -3 (x-2)
is the point slope form of given line
We know the slope intercept form of a line is given by
y = mx +c
Here y = -1 , x = 2 and m = -3
Substituting the values in slope intercept form equation we get
-1 = (-3)2 + c
⇒-1 = -6 + c
⇒-1+6 = c
c = 5
Thus the slope intercept form of equation is y = -3x+5
The first step in rewriting the function in a vertex form is (a) -4 must be factored from -4x² + 2x
<h3>How to determine the first step?</h3>
The equation is given as:
y = -4x² + 2x - 7
Factor out -4 from the first two terms of the equation
y = -4(x² + 0.5x) - 7
The above means that the first step in rewriting the function in a vertex form is (a) -4 must be factored from -4x² + 2x

Answer:
It takes 15 routines from each wheel on his inline skates when Shawn is coasting down a 500 cm long ramp
Step-by-step explanation:
Given:
- The length of the ramp: 500 cm
- The wheels on his inline skates are 32 cm in circumference.
As we know that the number of 32's can fit in 500 is the routine does each wheel make while Shawn is coating down the ramp. Hence, we take:
So it takes 15 routines from each wheel on his inline skates when Shawn is coasting down a 500 cm long ramp
Hope it will find you well.
m = -1
Step-by-step explanation:
-16m = 7 + 9
-16m = 16
m = 16 ÷ -16
m = -1
