Answer:
<h2>(-5, -28)</h2>
Step-by-step explanation:
The vertex form of a quadratic function <em>f(x) = ax² + bx + c</em>:
f(x) = a(x - h)² + k
(h, k) - coordinates of a vertex
We have <em>f(x) = x² + 10x - 3</em> in the vertex form <em>f(x) = (x + 5)² - 28</em>.
f(x) = (x - (-5))² + (-28) → h = -5, k = -28
Answer:
x=2°
Step-by-step explanation:
The given angles are corresponding angles.
Corresponding angles are congruent.
7x+9=9x+5
4=2x
x=2
Answer:
xy²z³
Step-by-step explanation:
An exponent is a way to indicate the number of times the factor is repeated. When it is 1, it is rarely shown.
x is repeated once, so will appear without an exponent
y is repeated twice, so will have an exponent of 2
z is repeated 3 times, so will have an exponent of 3
__
xyyzzz = xy²z³
_____
In plain text, an exponent is indicated with a caret (^).
xy^2z^3
