Answer:
y=-2/3 x +2
y=-x+2
Step-by-step explanation:
slope intercept form : y=mx+b
first find the slope :
two points from the graph : (0,2) (3,0)
y=b=2 when x=0 y = the constant b
m=(y2-y1)/(x2-x1)
m=0-2/3-0
m=-2/3
<h2>y=-2/3 x +2</h2>
question 26: two points from graph: (0,2),(1,1)
b=2 ( when x=0, y=b=2)
m=1-2/1-0
m=-1
<h2>y= - x+2</h2>
6x^2 + 8x - 9x - 12
= 6x^2 - x - 12
Answer:
Total percentage of income for taxes is 39%
Step-by-step explanation:
The percentage of gross income going to taxes and FICA is: 44% 31% 69% 11%
The average of this is: (44 + 31 + 69 + 11)/4
= 155/4
= 38.75
≈ 39%
The vendor has to sell 88 gingerbread houses to earn a profit of $665.60 and there is no chance that the vendor will earn $1500.
Given an equation showing profits of A Christmas vendor as
P=-0.1+30g-1200.
We have to find the number of gingerbread houses that the vendor needs to sell in order to earn profit of $665.60 and $1500.
To find the number of gingerbread houses we have to put P=665.60 in the equation given which shows the profit earned by vendor.
665.60=-0.1+30g-1200
0.1-30g+1200+665.60=0
0.1-30g+1865.60=0
Divide the above equation by 0.1.
-300g+18656=0
Solving for g we get,
g=[300±]/2*1
g=[300±
g=[300±]/2
g=(300±124)/2
g=(300+124)/2 , g=(300-124)/2
g=424/2, g=176/2
g=212,88
Because 212 is much greater than 88 so vendor prefers to choose selling of 88 gingerbread houses.
Put the value of P=1500 in equation P=-0.1+30g-1200.
-0.1+30g-1200=1500
0.1-30g+1500+1200=0
0.1-30g+2700=0
Dividing equation by 0.1.
-300g+27000=0
Solving the equation for finding value of g.
g=[300±]/2*1
=[300±
=[300±]/2
Because comes out with an imaginary number so it cannot be solved for the number of gingerbread houses.
Hence the vendor has to sell 88 gingerbread houses to earn a profit of $665.60 and there is no chance that the vendor will earn $1500.
