Answer:
so the axis of symmetry is x=4
Okay, so the equations would be:
x + 3y = 24
3y + 5x = 36
Imma use Substitution to solve this:
x = -3y + 24
3y + 5(-3y + 24) = 36
3y - 15y + 120 = 36
-12y + 120 = 36
-12y = -84
y = 7
x = -3(7) + 24
x = -21 + 24
x = 3
So the first number (x) would be 3 and the second number (y) would be 7.
Answer:
6 and 18
Step-by-step explanation:
a+b=24
5a-b=12
5a+a=6a
24+12=36
6a=36 so A on it's own is 6
24-6=b
b=18
hope this helps!
Answer:
Right angle triangle goes to 15m, 8m, 17m
Step-by-step explanation:
Square root of 15^2 + 8^2 is 17
(The use of a^2 + b^2 = c^2 - Pythagoras's Theorem)
So, 10m ,11m ,15m isn't a right angle triangle
Hope this helps!
F(x) = 5x - 2
f(-3/5) = 5(-3/5) - 2
f(-3/5) = -15/5 - 2
f(-3/5) = -3 - 2
f(-3/5) = -5
