Answer:
x = 
Step-by-step explanation:
Given a quadratic in standard form, ax² + bx + c : a ≠ 0
Then the axis of symmetry is a vertical line with equation x = h
where h is the x- coordinate of the vertex.
The x- coordinate of the vertex is
= - 
f(x) = 5x² - 3x + 5 ← is in standard form
with a = 5 and b = - 3, thus
= - 
=
Thus the equation of the axis of symmetry is x =
Answer:
x=(3u)/(10y)
Step-by-step explanation:
Answer:
y = -5
Step-by-step explanation:
<em>-</em><em>7</em> = <em>y </em><em>-</em><em>2</em><em> </em>
<em>y </em><em>=</em><em> </em><em>-</em><em>7</em><em> </em><em>+</em><em>2</em>
<em>y </em><em>=</em><em> </em><em>-</em><em> </em><em>5</em><em> </em>

3.4+0.4+4.17=7.97 you just have to try different combinations of different numbers with the decimals.
Answer:
-3/5
Step-by-step explanation:
First represent this with numbers. Less means subtraction -, times means multiplication *, is means equals =.
And let's represent "a number" with x.
63 - 15x = 72
Solve for x. First subtract 63 from both sides.
-15x = 72-63
-15x = 9
x = -9/15 = <u>-3/5</u>
