PLEASEEE HELP MEEEE!!!

Romashka [77]

Use substitution

From second equation:-

x = 13 - 5y, Substitute for x in the first eqaution:

(13 - 5y)^2 + y^2 = 13

169 -130y + 25y^2 + y^2 - 13 = 0

26y^2 - 130y + 156 = 0

26(y^2 - 5y + 6) = 0

26(y - 3)(y - 2) = 0

y = 2 , y = 3

From the second equation when y = 2, x = 13 - 5(2) = 3

and when y = 3, x = 13 - 5(3) = -2

So the solution is [3, 2} and {-2, 3}

Answer:

1.8 m

Step-by-step explanation:

h(T)=-9.8T^2+20T+1

Find the equation in slope-intercept form that describes a line through (–1, 1) and (2, 3)

Butoxors [25]

Answer:

y = 2/3x + 5/3

Step-by-step explanation:

The slope of the line is ...

slope = (change in y)/(change in x) = (3-1)/(2-(-1)) = 2/3

Then the point-slope form of the desired line can be written ...

y = m(x -h) +k . . . . . slope m through point (h, k)

y = 2/3(x +1) +1 . . . . slope 2/3 through point (-1, 1)

y = 2/3x + 5/3 . . . . . . simplify to slope-intercept form
