The terms point, line and plane, are the undefined terms in geometry. They are so basic that these terms are used to define other terms in geometry. You can describe a point to be indicating a location or position without any thickness. A line is a series of points that travel in one direction infinitely at both ends. A plane is a flat surface of area. The diagram of line ST intersecting plane M at point R is shown in the attached picture.

How to Find the vertex of f(x)=-8x^2-8x+7

charle [14.2K]

Answer:

The answer to your question is: (1/2, 5)

Step-by-step explanation:

Parabola f(x) = 8x² - 8x + 7

y = 8x² - 8x + 7

Vertical Parabola equation

( x - h)² = 4p (y - k) Transform the original equation to this form

8x² - 8x = y - 7

8(x² - x + ( )²) = y - 7 Complete squares

8 (x² - x + (1/2)²) = y - 7 + 2 Simplification

8 (x² - x + 1/4) = y - 5

(x - 1/2)² = 1/8 (y - 5)

Finally Vertex

(1/2 , 5)

Rowan has $50 in a savings jar and is putting in $5 every week. Jonah has $10 in his own jar and is putting in $15 every week. E

Harrizon [31]

Answer:

(3) Jonah's graph has a steeper slope than Rowan's

Step-by-step explanation:

First we are going to write the equations for the amount of money that each one save

y = a+bx

Where y: Amount of money in the jar

a: Initial saving

b: Money saved every week ( graph's slope )

x: Number of week

Then, for Rowan

y = 50 + 5x

and for Jonah

y = 10 + 15x

Initially Rowan's graph lies above Jonah's graph but this situation change with time.

It is always true that Jonah's graph has a steeper slope than Rowan's, because for Rowan's graph the slope is 5 and for Jonah's graph the slope is 15

Then the answer is:

(3) Jonah's graph has a steeper slope than Rowan's

A concession stand sold pizza slices, ice cream cones, and tacos at a basketball game. Pizza slices were sold for $2.75, ice cre

Ray Of Light [21]

Answer/Step-by-step explanation:

What we already know:

Pizza slices $2.75 - Ice cream cones $2.25 - Tacos $1.75

Total Items sold - 121 / Total amount of money - $260.75/ <u>$87.50 made from selling Tacos</u>

Tacos - 87.5 ÷ 1.75 = 50 Tacos sold -- 121 - 50 = 71 items

& 260.75 - 87.5 = 173.25 left

____________________________________

You can't sell half an Ice-Cream

Ice Cream - 71 - 1 = 70 -- 70 ÷ 2 = 35 -- 35 × 2.25 =

<h3>$78.75 made from Ice-cream cones</h3><h3>35 Ice- cream cones sold</h3><h3>**************************************************</h3>

Pizza slices - 71 - 70 = 1 -- 1 + 35 =

<u>36 Pizza slices sold</u>

36 × 2.75 =

<u>99 dollars made off of Pizza slices</u>
