Which system of equations is represented by the graph? a line is graphed through points negative 6 comma 7 and negative 1 comma 2. it intersects a parabola that opens up at these two points. y = x2 − 6x − 7 x − y = 1 y = x2 − 6x + 7 x + y = −1 y = x2 + 6x − 7 x − y = 1 y = x2 + 6x + 7 x + y = 1

The system of equation that is represented is:

Step-by-step explanation:

It is given that:

a line is graphed through points negative 6 comma 7 and negative 1 comma 2.

i.e. a line passes through (-6,7) and (-1,2).

The equation of line passing through (a,b) and (c,d) is given by:

Here (a,b)=(-6,7) and (c,d)= (-1,2).

Hence equation of line is:

Hence, the system of equation that satisfies these two points are:

( As in all the other options the equation of line i.e. second equation does not passes through the given points )

9) i can't see the angle so whatever it is just do this: cos(angle) x hypotenuse and then use that answer and they hypotenuse and plug it into this: (answer you just got)^2 + b^2 = (hypotenuse)^2. the first answer will be the answer of the adjacent side and the second answer after this equation will be the opposite side.

10) y = 14 x = √147 or 12.12435565

11) x = 4.8

12) x = 4.2

13) x = 9.3

14) pq: 13.2

qr : 17.6

angle p: 53º

15) angle c: 54.3º

angle a: 35.7º

16) h = 21040

v = 1841

step-by-step explanation:

10) 7/sin(30) = 14 = y

7^2 + b^2 = 14^2

49 + b^2 = 196

b^2 = 196 - 49

√b^2 = √147

x = √147

11) cos(70) x 14 = 4.788282007

x = 4.8

12) tan(25) x 9 = 4.196768923

x = 4.2

13) sin(31) x 18 = 9.270685348

x = 9.3

14) pq: sin(37) x 22 = 13.23993051

pq: 13.2

qr: cos(37) x 22 = 17.56998122

qr : 17.6

angle p: 180 - (37 + 90) = 53º

15) cos-1(7/12) = 54.31466529

angle c: 54.3º

angle a: 180 - (90 + 54.31466529) = 35.68533471

angle a: 35.7º

16) 4 x 5280 = 21120

cos(5) x 21120

h = 21039.63202

h = 21040

sin(5) x 21120

v = 1840.729287

v = 1841
