Ok! So, given a quadratic function<span>, </span>y<span> = ax</span>2<span> + bx + c, when "a" is positive, the </span>parabola <span>opens upward and the vertex is the minimum value. On the other hand, if "a" is negative, the graph opens downward and the vertex is the maximum value. Now, let's refer back to our original graph, </span>y<span> = </span><span>x2</span><span>, where "a" is 1.

Hope this helps.</span>

(03.01 LC) Given that h(x) = 3x −19, find the value of x that makes h(x) = 71. (5 points)
LekaFEV [45]
The function given is:
h(x) = 3x-19
we want to find the value of x that makes this function equal to 71. To do so, we will substitute h(x) with 71 and solve for x as follows:
h(x) = 3x - 19
71 = 3x - 19
3x = 71+19
3x = 90
x = 90/3 = 30

Can someone explain the properties and help me with this work?
Sever21 [200]
The first property is commutative  ( the numbers 38 and 677 are  swapped over)



Then we have the associative property ( where the paretheses are moved to get 38 and -38 together)

then the additive inverse ( 38 + (-38) = 0

and finally to get the 677 we use the additive identity property.

Type the correct answer in each box. If necessary, use / for the fraction bar(s). Given: AB || CD . If the coordinates of point
grandymaker [24]

Answer:

1. 11.2

2. -1.4

3. 12

Step-by-step explanation:

The equation of the line that passes through the points A(8,0) and B(3,7) is

\dfrac{x-8}{3-8}=\dfrac{y-0}{7-0},\\ \\y=-\dfrac{7}{5}(x-8).

To find the y-intercept, plug into this equation x=0:

y=-\dfrac{7}{5}(0-8)=\dfrac{56}{5}=11.2.

Two parallel lines have the same slope, so the equation of the line CD is

y=-\dfrac{7}{5}x+b.

This line passes through the point D(5,5), thus

5=-\dfrac{7}{5}\cdot 5+b\Rightarrow b=5+7=12.

Hence, the equation of CD is

y=-\dfrac{7}{5}x+12.
