Answer:
x intercept is x=3
y intercept is y=-3
Step-by-step explanation:
We can write this equation in a simpler way to find the values needed. Lets do it. Take:
x-y=3
And sum y in both sides, as we know the equality will maintain:
x-y+y=3+y
x = 3+ y
Now subtract 3 in both sides:
x-3 = y+3-3
x-3=y
So, we can rewrite our equation as y=x-3
The x intercept is a value of x such that the equation in equal to zero; in other words, is the value of x when y is zero. It is also called a zero root. Graphically, its the x value when the function passes trough the x-axis. Lets find if, we nned that:
x-3 = 0
If we sum 3 in both sides:
x-3+3=3
x=3
So, x=3 is x intercept
For finding the y intercept we need the value of y when x is zero. Graphically, is the value of y obtained when the function passes trough the y-axis. So, replace x with 0:
0-3=y
y=-3
Another way to get it is knowing that the y intercept in a polynomial is always the independent term, the one that has no x or y, which in this case is -3.
The angles of a triangle add to 180 degrees so the remaining angle must be 90°.
This triangle is half a square. It's one of the two tired triangles of trig, the other being half an equilateral triangle, 30°/60°/90°.
Answer:
b. Is because -3 because the the negative gets turned into a positive.
5. They are almost the same because subtraction change the negative to a positive and the -5+2 is the aftermath of what happend.
6. Its because the subtract a negative it cancels out and makes the number a positive.
I think it would be C because if you rotated it 90 degrees counter clockwise the A of X of x, y would then become negative
Answer:
Perimeter = 10x + 30
(Anyone can correct me if I'm wrong)
Step-by-step explanation:
Before solving the problem, we can make the following statements:
Perimeter = 2l + 2w
l = 2x + 7
w = 3x + 8
Using all of that, we can substitute for perimeter,
Perimeter = 2(2x + 7) + 2(3x + 8)
Perimeter = 4x + 14 + 6x + 16
Perimeter = 10x + 30
