This is a binomial
The answer is 336 inches squared
Answer:
x = -2, y = -3
Step-by-step explanation:
Solve for y:
If -3x + 9y = -21, and -3x +8y = -18, then -21 - y = -18
Add 18 to both sides:
-3 - y = 0, so y = -3
reconstruct new equation:
-3x + 9(-3) = -21, -3x + 8(-3) = -18
-3x + -27 = -21, -3x + -24 = -18
Using the new equation, solve for x:
add 24 to both sides of each equation :
-3x + -3 = 3, -3x = 6
x=<u>-2</u>
You have to add them both phils 4 times and add cliffs 5 times to get the sameanswer witch it 250
A slope intercept form is, take as an example: y=mx + b, because b is the number where the line intercepts the y axis.
Assuming the space inbetween -7x and 8y is a plus sign.
To get the equation in the right format, one must do the following:
8y=7x-1
y=7/8x-1/8
And theres your answer!
Note: The line intercepts the y axis in -1/8 :)
(If the space isnt a plus, i can answer diffrently in the comments.)
