Answer:
The right answer is Option 2:
Step-by-step explanation:
Point-slope form of equation of a line is given by:
Here m is slope of the line and (x1,y1) is the point from which the line passes.
Given
Slope = m = -3/4
Point = (x1,y1) = (2,-6)
We simply have to put these value into the general form of equation of line in point-slope form
Hence,
The right answer is Option 2:
Answer:
81 and above
Step-by-step explanation:
They have to be 81 and above
93+69+89+97=348
348/4=87 (average)
87=81=168
168/2= 84 (average)
Answer:
= -6
Step-by-step explanation:
-2 - (-4)
(-) - (+) = -
so, -2 - 4= -6
<span>We have the function: f ( x ) = ( x + 6 ) ( x + 6 ) = ( x + 6 )^2. This is the square of the binomial. It has only one zero ( only one x- intercept ). When f ( x ) = 0, ( x + 6 )^2 = 0. x + 6 = 0; x = - 6. Therefore point ( - 6 , 0 ) is the only x - intercept. Answer: D ) f ( x ) = ( x + 6 ) ( x + 6 ).</span>
Vietas formula tells us that the product of our two roots is equal to the constant term of a quadratic over the leading coefficient, so:
[tex] r_1r_2=-\frac{-10}{2} \implies 5*r_1=-5 \implies r_1=-1[\tex]
It also tells us that the b term in our quadratic is equal to the negative of the sum of the terms divided by the leading coefficient, so:
[tex] r_1+r_2=-\frac{b}{2} \implies 4=-\frac{b}{2} \implies b=-8 [\tex]
So, one of our roots is 5, the other is -1, and our b value is 8.
