Answer:
a =1 and b =2
Step-by-step explanation:
The standard quadratic is written in the form
ax^2 +bx+c =0
x^2 +2x -13 =0
a =1 and b =2
Answer:
fits under statistics category (also probability or math :\)
For find f(-2) of f(x)=7x+3, plug in -2 for x.
7(-2)+3=y
-14+3=y
y=-11
To find the rate, or the slope, you divide x/y. So 2/6 is 1/3. 3 over 9 is also 1/3. So the rate is 1/3. In rates you always divide, you don't mulitply or subtract or add to find the rate.
Answer:
option D. Neither
Step-by-step explanation:
y-4=7(x-6)
using (5,4):
4-4=7(5-6)
0=7(-1)
0=-7
using (6,5):
5-4=7(6-6)
1=7(0)
1=0
so option D is the answer
