Answer:

15 units

Step-by-step explanation:

Given the equation which models the path of a stone as:

$H(x)=-5x^2+10x+15$

At the time when the stone was thrown

x=0

Therefore:

$H(0)=-5(0)^2+10(0)+15\\H(0)=15$

The height of the stone at the time it is thrown is 15 units.

Solve this equation 90x-60y is equal to 68 and 90x-70y is equal to 91

Tanzania [10]

Answer:

Step-by-step explanation:

90x - 60y = 68.....multiply by -1

90x - 70y = 91

---------------------------

-90x + 60y = -68 (result of multiplying by -1)

90x - 70y = 91

---------------------------add

-10y = 23

y = -23/10 <===

90x - 60y = 68

90x - 60(-23/10) = 68

90x + 138 = 68

90x = 68 - 138

90x = - 70

x = -70/90

x = -7/9 <=====
