Answer:
Right angled triangle
Step-by-step explanation:
This is because the square root of the sum of the squares of 7 and 24 is 25 ( Pythagoras theorem) . This only works for right angled triangle.
Y = -2x + 8 = x - 4
x + 2x = 8 + 4
3x = 12
x = 4
y = -2(4) + 8 = -8 + 8 = 0
Solution is (4, 0)
Write down
15-80
Solve it by adding 15 to -80
The final answer is -65
Use your knowledge of place value to write your fraction
3 and 375/1000
now reduce. Both are divisible by 25.
3 15/40
oops, not done yet... we can still divide by 5
3 3/8
Done!
<span>y=-3x-4
slope = 3
perpendicular to line then slope = 1/3
answer
