Answer:
y = - x +
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Rearrange 4y = 5x + 3 into this form by dividing the 3 terms by 4
y = x + ← in slope- intercept form
with slope m =
Given a line with slope m then the slope of a line perpendicular to it is
= - = - = - , thus
y = - x + c ← is the partial equation
To find c substitute (3, - 2) into the partial equation
- 2 = - + c ⇒ c = - 2 + =
y = - x + ← equation of perpendicular line

Answer:
Step-by-step explanation:
a-number of advance tickets
s-number of same day tickets
a*40+s*25=2400
a +s =75
I solve with the substitution method
s=75-a
40a+25*(75-a)=2400
40a+1875-25a=2400
15a=2400-1875
15a=525
a=525/15
a=35
so s=75-35
s=40
Answer:
D; x -y = 22
3x + 2y = 246
Step-by-step explanation:
Let us have the bigger number as x and the smaller as y
The difference between the two is 22
Thus, we have it that;
x - y = 22
twice the smaller number; 2(y) added to thrice the larger 3(x) equals 246
3x + 2y = 246
So we have the two equations as;
x -y = 22
3x + 2y = 246
