Answer:
A
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k) = (1, 0) , thus
y = a(x - 1)² + 0
To find a substitute the coordinates of the y- intercept (0, 1) into the equation
1 = a(- 1)² = a , thus
a = 1
y = (x - 1)² → A
Answer:
<h2><em>
If digits can be repeated: 36</em></h2><h2><em>
If the digit can not be repeated: 30</em></h2>
Step-by-step explanation:
<em>If digits can be repeated:</em>
On the first and second place we have 6 digits to choose from.
Therefore we have 6 · 6 = 36 two-digit numbers.
<em>If the digit can not be repeated:</em>
On the first place we have 6 digits to choose from and on the second place we have 5 digits to choose from.
Therefore we have 6 · 5 = 30 two-digit numbers.
p² - 12p = 13
p² - 12p - 13 = 0
p² - 13p + p - 13 = 0
p(p) - p(13) + 1(p) - 1(13) = 0
p(p - 13) + 1(p - 13) = 0
(p + 1)(p - 13) = 0
p + 1 = 0 or p - 13 = 0
- 1 - 1 + 13 + 13
p = -1 p = 13
The solution set of the equation is {-1, 13}.
Answer: -3x+y=-4
Step-by-step explanation:
Standard form is Ax+By=C. In y=Mx+b form, it would be y=3x-4. To put it into standard form you subtract 3x from both sides. So then you have -3x+y=-4.
