Line QR goes through points Q(0, 1) and R(2, 7). Which equation represents line QR?
kari74 [83]
For this we will use equation that gives us equation of line that goes through 2 given points.

that equation is:
 y - y1= \frac{y2 - y1}{x2 - x1} (x - x1)

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.

Just keep getting more homework.<br> i really need help
rusak2 [61]

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

I can't seem to figure this one out, this is all the info that was given:
vazorg [7]

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
