Answer:
x = 0
Step-by-step explanation:
A
First, I’m going to the line is question into slope intercept form.
y + 10 = -5x + 5
y = -5x + 5 -10
y = -5x -5
y + 10 = -5 (x - 1) becomes y = -5x -5 in slope intercept form. I will call this line ‘line 1’
A becomes y = 5x -15 in slope intercept form
B becomes y = -5x + 25 in slope intercept form
C becomes y = -5x -5 in slope intercept form
D becomes y = -5x + 10 in slope intercept form
C is the same line as line 1. Any point that is on line 1 is also on line C, so C cannot be it.
Notice that line B and D have the same slope but different y-intercepts as line 1. That means these lines are parallel (not the same line though - different y intercepts) to line 1, so they will never intercept.
Line A has a different slope vs line 1, so they will eventually intersect only once
The numbers are {10, 11, 12, ... , 23, 24}.
Can we divide 11 by 1? yes. can we divide the other digit of 11 by 1? yes. Thus, 11 satisfies the criterion "they are divisible by each of their digits."
What about 12: is 12 divisible by 1? YES. Is 12 divisible by 2? YES.
And so on.
Answer:
x = 3
y = -2
Step-by-step explanation:
x - 2y = 7
y = -x + 1
x - 2y = 7
x - 2 ( -x + 1 ) = 7
3x - 2 = 7
3x = 9
x = 3
y = -x + 1
y = -3 + 1
y = -2
