395, 390, 398 those are the numbers
1. 15+37=?
- 15=10+5 (given on the diagram)
- 37=30+7 (given on the diagram)
- add digits to digits 5+7=12=10+2
- add tens to tens 10+30+10=50
- add tens and digits 50+2=52.
2. 22+49=?
- 22=20+2 (given on the diagram)
- 49=40+9 (given on the diagram)
- add digits to digits 2+9=11=10+1
- add tens to tens 20+40+10=70
- add tens and digits 70+1=71.
3. 38+26=?
- 38=30+8 (given on the diagram)
- 26=20+6 (given on the diagram)
- add digits to digits 8+6=14=10+4
- add tens to tens 30+20+10=60
- add tens and digits 60+4=64.
Answer: 1) 52; 2) 71; 3) 64.
i) first you combine the like terms; 3x² and x², then 4x and -8x, then -7n and -1.
Then you would get 4x²-4x-8.
You then cannot simplify further. so your answer would be 4x²-4x-8.
Answer:
slope of line is 3
y-intercept of line is -13
Explanation:
The general formula of the linear line is:
y = mx + c
where:
m is the slope of the line
c is the y-intercept
The given line is:
y = 3x - 13
Comparing the given line with the general formula, we would find that:
m (the slope of the line) is 3
c (the y-intercept) is -13
Hope this helps :)
Answer:
PY = 8
Step-by-step explanation:
Lets run down the other three to show why they're wrong
<em>MY=8</em>
By P.T, that's wrong (PERPENDICULAR)
<em>PM=MY </em>
We can't prove that with the given
XY=42
Again, by P.T., this is false
BTW: You can prove PY=8 by proving XMP congruent to YMP by SAS
