Answer:
when the square on the hypotenuse of a right-angled triangle is equal in to the sum of the squares on the other two sides
Step-by-step explanation:
let's say......
h = ?
o = 4
a = 4
a^2+o^2=32
square root 32
5.65685424949
that is the value for h
Answer:
x = 0, y = -2
Step-by-step explanation:
-3x - 4y = 8 (1)
-4x - 3y=6 (2)
Multiply (1) by -4 and (2) by -3, we have:
12x + 16y = - 32 (3)
12x + 9y= -18 (4)
Subtract (4) from (3), we have:
(12x + 16y) - (12x + 9y) = - 32 - (-18)
<=> 7y = - 14
=> y = - 2
Replace y with - 2 in (3), we have x = 0
Answer:
$16
Step-by-step explanation:
if 5=20 then 20÷5=4 and 4x4=16
You have to use y=mx+b
so you plug it in 4=6(3)+b
subtract 18 from both sides
-14=b
b is the y-intercept so it would be .... y=6x-14
you plug 27 in for x
y=6(27)-14
y=148
