Answer:
k=5
Step-by-step explanation:
step 1
Find the equation of the line f(x)
we have the points
(-4,0) and (-2,2)
<em>Find the slope m</em>
Find the equation of the line in point slope form
we have
substitute
Remember that
f(x)=y
so
step 2
Find the equation of the line g(x)
we have the points
(-4,0) and (-2,-10)
<em>Find the slope m</em>
Find the equation of the line in point slope form
we have
substitute
Remember that
g(x)=y
so
Remember that
------>
therefore
k=5
X= 20
Work:
7 times 2 is 14 so you will
muliltiply 10 by 2 which is 20.
Answer:
no
negative 4 i think im dumb tho
Step-by-step explanation:
Answer:
15%
Step-by-step explanation:
Given that,
Initial earning is $20 for each lawn and this summer she raised her price to $23 per lawn. We need to find the percent increase of peggy's charges. It can be given by :
Putting the values in above formula, we get :
So, there is 15% increase in the peggy's charges.
Use the slope formula y2-y1/x2-x1
3-(-7)/1-(-1) = 10/2 = 5
To find the y-intercept:
y=5x+b
3=5(1)+b
3 = 5+b
-5 -5
-2=b
The equation of the line that passes through (-1,-7) and (1,3) is
y=5x-2
