Answer:
it is a simultaneous equation.
the -9d can be cancelled to find the answer
Answer:
y= -1/2x-1
Step-by-step explanation:
1) put the equation in y-intercept form to find the slope of the original line 2x+4y=8
y=8/4-2x/4
y=2-1/2x
slope of second line will be -1/2
2) put point into the point-slope form (2,-2)
y-(-2)= -1/2(x-2) now simplify
y+2= -1/2x+2/2
y+2 = -1/2x + 1
y+2-2=-1/2x + 1 -2 ====>>>> y= -1/2x-1
Subtract 5 from both sides.
Subtract 8n from both sides.
Divide both sides by -9 to solve for n.
The value of n is
-4/9.
Slope as an (improper fraction)-9/7, it can’t be simplified
Answer:
307.5$
Step-by-step explanation:
150$. 105% of it added.
Since 105% is 1.05, multiply the percentage by the cost to get the money added.
150*1.05=157.5
Then ADD it to the price/savings.
150+157.5=307.5$
