Answer: Today's temperature : 2t -10
Step-by-step explanation:
Hi, to write the expression of the statement given we have to analyze each phrase:
<em>Twice yesterday's temperature, t.</em> If t is yesterday’s temperature, twice that temperature equals 2t.
<em>The temperature today was 10 degrees colder than</em>: It means that we have to subtract 10 degrees :(-10)
Mathematically speaking:
Today's temperature : 2t -10
where t = yesterday's temperature

Step-by-step explanation:
Answer:
y = 2(x - 2)² + 3 vertex form
y = 2x² - 8x + 11 standard form
Step-by-step explanation:
Vertex form
y = a(x - h)² + k
(h, k) = (2, 3)
y = a(x - 2)² + 3
To find "a" plug in the y-intercept (0, 11)
11 = a(-2)² + 3
11 = 4a + 3
Subtract 3 from both sides
8 = 4a
a = 2
y = 2(x - 2)² + 3
Expand
y = 2(x² - 4x + 4) + 3
y = 2x² - 8x + 11
Exact Form:
x = 34/7
Decimal Form:
x= 4. 857142
Mixed Number Form:
x= 4 6/7
