Answer:
Linear expression
Step-by-step explanation:
If you have an expression with = sign, it becomes an equation
Without the = sign, it's just an expression
Just substitute the value of x = 7
= 8(2.3 x)
= 8(2.3 * 7)
= 8(16.1)
= 128.8
In short, Your Final Answer would be 128.8
Hope it help
Answer:
LaTasha is correct. There is no correlation between x and y. The slope of the line of best fit is zero, which shows that there is no negative or positive correlation.
If the parabola is rotated so that its vertex is (h,k) and its axis of symmetry is parallel to the y-axis, it has an equation of (x - h)^2<span> = 4p(y - k)</span><span>, where the </span>focus<span> is (h, k+p) and the </span>directrix<span> is y = k - p. So, we need to determine the values from the equation.
</span><span>y=1/28(x-4)^2-5
</span>(x-4)^2 = 28(y+5)<span>
(h,k) = (4, -5)
p = 7
focus= </span>(h, k+p) = 4,2
directrix = y = k - p = -12
Hope this answers the question.
