Y = 25x + 32
y = 5x² + 25x - 13
how do i find the two pairs of coordinates

(-3,-43) and (3,107)

Step-by-step explanation:

input 25x+32 for y

25x+32=5x²+25x-13

32=5x²-13

-5x²=-45

x²=9

x=+-3

which means you separate the solution

x= -3

x= 3

then input the answers you got for x, in both equations. Then you'll get your y.

y=25(-3)+32

-43

Then check your answer.

Then input the other answer you got for x.

I may be wrong, but I tried and checked my answers.

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
