Answer:
Step-by-step explanation:
1st on is one solution
2nd one is no solution (the lines have the same slope but different y- intercepts
3rd is infinitely many solutions (the equations are the same)
Answer:
y axis
Step-by-step explanation:
When you set up an ordered pair, yi always has to be - 1 and x can be anything. To show you what this means, draw an x,y axis.
Plot a few points. Try these (0,-1) (2,-1) and (-2,-1) Now join them. They make a straight perpendicular line.
The line is parallel to the y axis.
A line parallel to the x axis has all the x's the same.
(-1, 1), (-1,2) (-1,4)

Answer:
For bag C
Step-by-step explanation:
Bag C has more blue marbles than red ones
Answer:
<u>Given</u>
- ΔTQR is right
- QS is altitude
- ΔRSQ and ΔTSQ also right
- m∠TQS = 42°, RS = 26 cm
∠RQS and ∠TQS are complementary with ∠TQS, so are 48°
a)
- ∠QRS is the another one with 42°
b)
<u>Find QS first</u>
- 26/QS = tan 48°
- QS = 26 / tan 48° = 23.4
<u>Find QT next</u>
- QS/QT = cos 42°
- QT = QS / cos 42° = 23.4 / cos 42° = 31.5 (rounded)
