Answer:
16.81 and 12.25
Step-by-step explanation:
Answer:
(–3, –4)
Step-by-step explanation:
Given pair of linear equation
-4x+y = 8
=> y = 8 + 4x _____(1)
x - 5y = 17 (2)
substituting value of y from equation 1 in equation 2 we have
x - 5(8 + 4x) = 17
=> x - 5*8 -5*4x = 17
=> x - 40 - 20x = 17
=> -40 - 19x = 17
=> -19x = 17+40 = 57
=> x = 57/-19 = -3
Thus, x = -3
y = 8 + 4x = 8 +4(-3) = 8 -12 = -4
Thus, y = -4
Hence, paired solution for given equation is (–3, –4).
Answer:
x² +11x +28
Step-by-step explanation:
(x +4) (x+7)
take the first x and multiply by x and then the 7 which gives you x² +7x
then take the 4 and multiply it by the x and the 7 which gives you 4x + 28
add all like terms
Answer:
14 is the answer of x in this question
