Answer:
f(- 5) = 25
Step-by-step explanation:
To evaluate f(- 5) , substitute x = - 5 into f(x) , that is
f(- 5) = - (- 5)² - 10(- 5) = - 25 + 50 = 25
Answer:
no
Step-by-step explanation:
We can simplify 6/12 by dividing the top and bottom by 6
6/12 =1/2
3/5 and 1/2
The common denominator is 10
3/5 *2/2 =6/10
1/2*5/5 = 5/10
They are not equal
Answer:
45
Step-by-step explanation:
Since the values are relatively small substitute i = 1 to 5 into 3i and sum
(3 × 1) + (3 × 2) + (3 × 3) + (3 × 4) + (3 × 5)
= 3 + 6 + 9 + 12 + 15
= 45
Answer:
Hello,
|FD|=15
Step-by-step explanation:
Since the triangles are similar, the bissects are also.
k*35=21 ==> k=21/35
k*25=|FD|
|FD|=(21/35)*25=15
Answer:
The equation of the line in point slope would be y + 1 = 3(x + 9)
Step-by-step explanation:
In order to find the equation in point-slope form, use the base form and put in the known information.
y - y1 = m(x - x1)
y - -1 = 3(x - -9)
y + 1 = 3(x + 9)
