Answer:
Step-by-step explanation:
The given points are zero's or roots of the function.
<u>We can put the equation as:</u>
- y = (x + 1)(x - 3) = x² -3x + x - 3 = x² - 2x - 3
This is option A
The average adult has about 1.2 to 1.5 gallons of blood. So less than 5 gallons.
The answer is 42. Because 17+4=21 and 21 times 2= 42
22.
Alternate angles23.
4: (

, substitute b with 10 and a with 20 and you get 4.)
24.
0.28: 0.12 + 0.60 = 0.72. Probability is always out of 1, so 1 - 0.72 should give you the probability of losing, which is 0.28.
Answer:
My example:
1. Get the equation in the form y = ax4 + bx + c
2. Calculate -b / 4a. This is the x coordinate of the vertex
3. To find the y coordinate of the vertex, simply plug the value -b / 4a into the equation for x and solve for y.
Step-by-step explanation:
y=2x^2 -16x +30
vertex: ( 4, -2)
Focus: (4, -15/8)
Axis of symmetry: x = 4
Directrix: y = -17/8
