Answer:
Slope: undefined
Equation: x=-3
Step-by-step explanation:
To find the line that passes through the points, you first want to find the slope. The formula for slope is 
. Once we have the slope, we can use any given point to plug in to find the y-intercept.
We can see that the slope is undefined. If we look at the point, we notice that they both have the same x-coordinate. This let's us know that the equation is x=-3.
Yes because $56 + 6.25% = 56.0625
And 15% of 56.0625 is 8.409375
So, 56.0625 + 8.409375 = $64.471875 making the total right under $65.
Answer:
Dom = R - {-4}
Range = R - {0}
Step-by-step explanation:
Answer:
x = 2
y = -3
z = 4
( 2 , -3, 4 )
Step-by-step explanation:
x + y + z = 3 ---- i
x – y =5 ---- ii
y - z = -7 ---- iii
ii + iii
x - z = -2 ---- iv
i + ii
2x + z = 8 --- v
iv + v
3x = 6
x = 2
x=2 substitute for v
z = 4
x =2 substitute for ii
y = -3
