Answer:
(x,y)=(7,2)
Step-by-step explanation:
For this we will use equation that gives us equation of line that goes through 2 given points.
that equation is:

now we implement our given coordinates.
let Q be point 1 and R be point 2
y - 1 = 6/2(x - 0)
y - 1 = 3x
Answer is b.
Answer:
What's the question its asking so I can help?
Answer:
1. x = 1, y = -3
2. x = 3, y = 4
Step-by-step explanation:
Here, we want to solve the sets of simultaneous equations;
a) -y = 5x-2
-3y = -5x + 14
substitute 1 into ii
3(5x-2) = -5x + 14
15x - 6 = -5x + 14
15x + 5x = 14 + 6
20x = 20
x = 20/20
x = 1
from;
-y = 5x - 2
y = -5x + 2
y = -5(1) + 2
y = -3
b) -2y = -6x + 10
2y = x + 5
Substitute ii into i
-(x + 5) = -6x + 10
-x - 5 = -6x + 10
-x + 6x = 10 + 5
5x = 15
x = 15/5
x = 3
2y = x + 5
2y = 3 + 5
2y = 8
y = 8/2
y = 4
Answer:
4a + 4
Step-by-step explanation:
f(x) = x² + 2
f(a) = a² + 2
f(a+2) = (a+2)² + 2
f(a+2) − f(a) = (a+2)² + 2 − (a² + 2)
f(a+2) − f(a) = a² + 4a + 4 + 2 − a² − 2
f(a+2) − f(a) = 4a + 4
