4x+6y=8
3x+y=9
y = 9 - 3x
4x + 6( 9-3x ) = 8
4x + 54 - 18x = 8
14x = 46
x = 23/7
y = 9 - 3(23/7)
y = 9 - 69/7
y = - 6/7
The area of the triangle is 24 ft² while the area of the square is 64 ft²
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Area of triangle = (1/2) * base * height = 0.5 * 8 * 6 = 24 ft²
Area of square = 8 ft * 8 ft = 64 ft²
The area of the triangle is 24 ft² while the area of the square is 64 ft²

A
This is one of those questions that is hard to explain, because I don't know what you know. I'll start with the most obvious reason I know. At x = -1 the top and bottom of the function is 0/0. zero/zero can give indeterminate results and you must look for other ways of explaining what is going on. Here's another thought which is less reliable.
The fraction factors.
(x + 1)*(x - 1)
============
(x + 1)
The two common factors cancel and you are left with f(x) = x - 1
If you have a graphing calculation you can put this in as y = x - 1 and you see that it is a straight line.
Question B is much nicer
when you put x = 1 into the fraction, you get 0 /2 which gives you 0. That's much easier to handle because the answer is 0.
you are still graphing y = x - 1, but this time the graph is much more well behaved.
Answer:
-4
Step-by-step explanation:
-√16
-4
Answer:
20
Step-by-step explanation:
P/5 + 6 = 10
P/5 = 10 - 6
P/5 = 4
(cross multiply)
P = 5 × 4
P = 20
