Mathematics
1 answer:
omeli [17]3 years ago
7 0

Answer:

D

Step-by-step explanation:

y = -x^2 + x - 1

y = -x -1

-x-1 = -x^2 + x -1

x^2 -2x = 0

x( x-2) = 0

x1= 0 , x2 = 2

y(0) = 0-1 = -1

y(2) = -2-1 = -3

(0, -1) & (2, -3)

It is given that R=2q-5 and Q=3p+2. Find the numerical value of R when p=3​
saveliy_v [14]

Answer:

R = 17

Step-by-step explanation:

R = 2q - 5

Q = 3p + 2

Find the numerical value of R when p = 3

R = 2q - 5

R = 2(3p + 2) - 5

R = 6p + 4 - 5

R = 6p - 1

When p = 3

R = 6(3) - 1

R = 18 - 1

R = 17
