Answer: d. 21
Step-by-step explanation:
The formula to find a discriminant is b^2-4ac.
ax^2+bx+c is the quadratic equation. In your equation, -1 is a, -1 is b, and 5 is c. Now we can plug in the numbers into the discriminant formula b^2-4ac!
(-1)^2-4(-1)(5)=
1-4(-5)
1+20
21
The discriminant is 21.
Hope this helps!
Answer:
the slope of the line would be 3/4
Step-by-step explanation:
to find this use your equation for slope: y2-y1/x2-x1
this will give you 5-2/4-0
simplified it is 3/4
another way to know the slope is that the slope will be rise/run, so since the line is going up 3 places and over 4 places, your slope would be 3/4
Answer:
2 = c
Step-by-step explanation:
ABC is a right triangle and in right triangles the square value of hypotenuse (C in this case) is equal to sum of other two side's square length
4^2 + 6^2 = c^2
16 + 36 = c^2 add terms
52 = c^2 find the root for both sides
2 = c
