Which statement is true about the graphs of the two lines and ?

1 answer:

5 0

The true statement about the graphs of these two lines are The lines are perpendicular to each other because -8 and 1/8 are opposite reciprocals of each other. First option is right

<h3>How to solve for the lines</h3>

The equation of the graph is in its intercept form. This is given as y = mx + b. m is the slope while be is the intercept.

The slopes of the lines have \been given as -8 and 1/8. These numbers are negative reciprocals when they are multiplied,

-8 * 1/8

= -1

Hence the first statement is right.

Answer:

$y = {x}^{2} - 2$

Or if you want with the value of h too.

$y = {(x - 0)}^{2} - 2$

Step-by-step explanation:

$y = a {(x - h)}^{2} + k$

Find the value of h and k by using the formula.

$h = - \frac{b}{2a} \\ k = \frac{4ac - {b}^{2} }{4a}$

From y = x²-2

$a = 1 \\ b = 0 \\ c = - 2$

Substitute these values in the formula.

$h = - \frac{0}{2(1)} \\ h = 0$

Therefore, h = 0.

$k = \frac{4(1)( - 2) - {0}^{2} }{4(1)} \\ k = \frac{ - 8}{4} \\ k = - 2$

Therefore, k = - 2.

From the vertex form, the vertex is at (h, k) = (0,-2). Substitute h = 0, a = 1 and k = -2 in the equation.

$y = a {(x - h)}^{2} + k \\ y = 1 {(x - 0)}^{2} - 2 \\ y = {(x)}^{2} - 2 \\ y = {x}^{2} - 2$

These type of equation where b = 0 can also be both standard and vertex form.

f each bowl of ice cream creates a profit of $0.35, what could be the profit made from the 3/4 of a gallon of ice cream?

WINSTONCH [101]

Answer:

$4.2

Step-by-step explanation:

<u>Full question is:</u>

<em>At an ice cream social, 3/4 of a gallon of ice cream is split into bowls, each containing 1/16 of a gallon of ice cream. How many bowls of ice cream can be made? </em>
<em>If each bowl of ice cream creates a profit of $0.35, what could be the profit made from the 3/4 of a gallon of ice cream?</em>

<h3>Solution</h3>

<u>Number of bowls is:</u>

3/4 ÷ 1/16 = 3/4*16 = 12 bowls

<u>Profit made:</u>

12*$0.35 = $4.2
