Answer:
4. AB=4
Step-by-step explanation:
Transitive property is like substitution, or that's how I like to think of it. Since we have 2 common variables and 2 equations, we can "link them together". Replacing x with 4, you get AB=4.
Answer:
x-intercept: (9,0)
y-intercept: (0,-9)
Step-by-step explanation:
The x-intercept and y-intercept is the point at which a line intersects the x-axis and y-axis, respectively. All points on the x-axis have a y-value of 0, while all points on the y-axis have an x-value of 0. Thus, to find the x and y intercepts, substitute 0 for one of the variables in the equation, then solve for the other.
1) To find the x-intercept, substitute 0 for y. Then, isolate x.

So, the x-intercept must be (9,0).
2) To find the y-intercept, substitute 0 for x. Then, isolate y.

So, the y-intercept must be (0,-9).
Answer:
already in standard form
Step-by-step explanation:
the equation of a quadratic in standard form is
y = ax² + bx + c ( a ≠ 0 )
y = x² + 4x + 3 ← is in standard form
with a = 1 , b = 4 , c = 3
Answer:
50 + 25x = 1600
Step-by-step explanation:
If it’s X-27=62, you have to isolate X. So you would put your -27 on the other side but in doing that you have to change your negative 27 to a positive as it is switching sides. So it would now be, X=62+27, which is 89. Final answer, X=89
