Given line : y = 5
=> y = 0×x + 5
Comparing it with y = mx + c
slope of line, m = 0
Thus, this line is parallel to x axis.
A line perpendicular to it will be parallel to y axis.
So the perpendicular line will be of the form: x = k
where k is a constant.
It passes through (-7,-5)
Thus
x = k
=> -7 = k
=> k = -7
Thus, equation of perpendicular line is x = -7
Answer:
B?
Step-by-step explanation:
De guy was Carl Friedrich Gauss, aka the prince of math
so he noticed that
1+100=101
2+99=101
etc
so there wer some pairs
how many?
there wer 100 numbers from 1 to 100 so
100/2=50
50 pairs
so then 101 times 50 pairs=5050 total
17) y-5=-3(x+2)
y=-3x-1
-3x-1
-3x=1
x=-1/3
18)y+1=4/5(x-5)
y=4x/5-5
4x/5-5=0
4x x5/5-5x5=0x5
4x-5x5=0x5
4x-25=0
4x=25
x=25/4
19)0=x-4
x-4=0
x=4
20)y-3=-1/2(x+4)
y=-x/2+1
-x/2+1=0
x=2
21)y-4=1/3(x+3)
y=x/3+5
x/3+5=0
x/3=-5
x=-5x3
x= -15
22) y+5=3(x+3)
y=3x+4
3x+4=0
3x=-4
x=-4/3
23) y-3=-2(x+2)
y=-2x-1
-2x-1=0
-2x=1
x=-1/2
24)y-1=5/3(x-3)
y=5x/3-4
5x/3-4=0
x=4x3/5
x=12/5
Divide 45 by three because it is 3:4 of the cost then mutiply it by four so e entire cost would be 60.
