Answer:

Solutions: (0,11) ; (1,15) ; (2, 19)

Step-by-step explanation:

y - 3 = 4(x +2)

y - 3 = 4x + 8

y = 4x + 8 + 3

y = 4x + 11

When x = 0 , y = 11                      (0,11)

When x = 1  ; y = 4 +11 = 15         (1, 15)

When x = 2 ; y = 8 + 11 = 19        (2 , 19

In the isosceles triangle ABC, we have AB=AC=4. The altitude from B meets AC at H. If AH=3(HC) then determine BC.
Inga [223]

Answer:

BC=√7

Step-by-step explanation:

AC=4

AC=AH+HC

=3HC+HC

=4HC

HC=1/4AC=1/4×4=1

AH=3HC=3×1=3

BH⊥ AC

AB=AC=4

BC=\sqrt{AB^2-AH^2} =\sqrt{4^2-3^2} =\sqrt{16-9} =\sqrt{7}
