Answer:
Greater x =+ 7
Lesser x = -7
Step-by-step explanation:
G(x) = -10x2+ 490
Let the left side = 0
So we have
0= -10x2+ 490
Solving the above now by allowing the variable with the coefficient of x cross the equal sign.
10x²= 490
Dividing by 10
X²= 490/10
X² = 49
Taking the root of both sides
X= √49
X = + 7or -7
Bigger x =+ 7
Smaller x = -7

Step-by-step explanation:
There are 11,440yd in a milw
The x-intercept will be the value of x when y=0. The solutions to (x+1)(x+2)=0 are -1 and -2 since we can substitute them in to have one of the values in parentheses equal to zero, so our x-intercepts are (-1, 0) and (-2, 0). The y-intercept is the value of y when x=0, or (0+1)(0+2)=2. Therefore, the y-intercept is (0, 2).
