Answer:
Slope of the line y = x + 10 is 1. So, any straight line perpendicular to this must be having slope of (-1).
Let, the line be y = - x + b and it passes through (15, -5).
So, 15 = 5 + b
b = 10.
So, equation of that line: y = -x + 10
Or, x + y = 10.
Y-intercept of the line = 10 units.
Answer:
Yes.
Step-by-step explanation:
This relation is a function because each input has one and only one output, i.e. 2 yields 1, 4 yields 2, 6 yields 3, 8 yields 4 and 10 has an output of 3. Therefore, it is a function.
Answer:
A. 45 + b = 88, so b = $43
Step-by-step explanation:
We know that he's earned $45 dollars, plus b dollars for babysitting. This gives us the first part of the equation (45 + b). The total amount he earned was $88, so 45 + b = 88.
Then, you can solve it.
45 + b = 88
-45 -45
0 + b = 43
b = 43
This means he earned $43 babysitting his younger brother.
Hope this helps :)
Because these are on opposite sides of the parallelogram, x + 33 = 4x + 9.
This gives you x = 8; OL = 41, NM = 41.
