Answer:
Step-by-step explanation:
2x - 9y = 23
5x - 3y = -12x - 9y = 23
5x - 3y = -12x - 9y = 23
5x - 3y = -12x - 9y = 23
5x - 3y = -1
Answer:
use the formula y2 - y1 /x2 - x1
y1 = 6
y2 = 9
x1 = 1
x2 = 4
Step-by-step explanation:
9 - 6/ 4 - 1
3/3
=1
slope is 1
Answer:
2y<-22
Step-by-step explanation:
2y is 2 times y
<-22 is less than -22
The y-intercept can be found by plugging in x=0.
Answer:
y= -21; m∠MNO=40°.
Step-by-step explanation:
1) m∠MON+m∠MNO=90°;
2) -3y-13°-2y-2°=90°;
5y=-105°; ⇒ <u>y= -21</u>;
3) <u>m∠MNO</u>=-2y-2°=42°-2°=<u>40</u>°.
