6 0

easiest way is just pick some small simple integers for x and plug it into the equation to find y

(0,-8)
(1,-7) 1^2-8 = -7
(2,-4) 2^2-8 = 4-8 = -4
(3,1) etc.
(4,8)
(5,17)
(6,28)

-3 | 9-8=1 | (-3, 1)

-2 | 4-8= -4 | (-2, -4)

-1 | 1-8=-7 | (-1, -7)

0. | 0-8=-8 | (0, -8)

1 | 1-8=-7 | (1, -7)

Joe has eaten 2/5 of a pizza. James has eaten 1/7. How many times more pizza has Joe eaten than James?

11Alexandr11 [23.1K]

First let's make the denominators of the fractions equal.
To do this, we have to find a number which both 5 and 7 divide into.
The smallest number that does this is 35.

2 --> Multiply the numerator by 7
--
5 --> Multiply the denominator by 7 to get 35

= 14/35

1 --> Multiply the numerator by 5
--
7 --> Multiply the denominator by 5 to get 35

= 5/35

Joe has eaten 14/35 and James has eaten 5/35.
14 / 5 = 2.8

<u>Joe has eaten 2.8 (or 2 4/5) times more pizza than James.</u>

Answer:

Question 1: She needs 12 blue beads and 48 black beads.

Question 2: She needs 10 blue beads and 25 black beads.

Step-by-step explanation:

I used ratios

question one's ratio is 3:12 and the second one's ratio is 4:10. If you keep that ratio consistent than those are the numbers you get based on the number of beads long she wants her necklace.

that's my best guess

What is the length of the diagonal, d, of the rectangular prism shown below?

vodomira [7]

Answer:

<h2>The diagonal of the volumetric figure is 7 units long.</h2>

Step-by-step explanation:

The figure is attached.

Notice that the dimensions of the prism are

$w=2\\l=3\\h=6$

First, we need to find the diagonal of the rectangular face on the base, this diagonal of the base is part of the right triangle formed by the diagonal of the volume, that's why we need it.

Let's use the Pythagorean's Theorem

$d_{base}=\sqrt{2^{2} +3^{2} }=\sqrt{4+9}=\sqrt{13}$

This diagonal of the base is a leg in the right triangle formed by the diagonal of the volume.

Let's use again Pythagorean's Theorem

$d_{volume}=\sqrt{(\sqrt{13} )^{2} +(6)^{2} } =\sqrt{13+36}=\sqrt{49}\\ d_{volume}=7 \ units$

Therefore, the diagonal of the volumetric figure is 7 units long.
