HEY PLEASE I NEED HELP IM OFFERING 30 POINTS

Mathematics
1 answer:
Levart [38]3 years ago
8 0

Answer:

the first option, (-4, 6)

Step-by-step explanation:

for this question, we can use the substitution method. this is where we substitute the coordinates in the answer choices into the given system of inequalities or equations to determine which one is true.

1. (-4,6)

x + 4y > 12

-4 + 4(6) > 12

20 > 12 is true

now we can substitute the second inequality.

3(6) > -4 + 6

18 > 2 is true, therefore making this set of points true.

it may be helpful to substitute the rest of the values of x and y into the inequalities to verify your answers :

5 + 4(2) > 12

5 + 8 > 12

13> 12 is true

3(2) > 5 + 6

6 > 11 is not true

the rest of the answer choices are also not true.

I hope this helped you!

Juliette [100K]

Answer:

93 miles

Step-by-step explanation:

Use the distance formula:

d = \sqrt{(x2 - x1)^2 + (y2 - y1)^2}

Plug in the values:

d = \sqrt{(121 - 57)^2 + (79 - 11)^2}

d = \sqrt{4096 + 4624}

d = \sqrt{8720}

d = 93.4

= 93 miles

The formula for the surface area of a sphere is 4πr^2

This can be used in the following way, getting the diameter at 18.3:
18.3/2 = 9.15
Saying PI is 3.14 you can do this:

SA = 4*3.14*9.15^2 = 1051.6 m^2

Formula for volume is:
(4/3)πr^3

V = (4/3)*3.14*9.15^3 = 3207.2 m^3

Which of the following is the product for (x+4)(x-2)?
larisa86 [58]

Answer:

A

Step-by-step explanation:

X times x is x squared then x times - 2 is - 2x but 4 times x is 4x. So 4x plus - 2x is 2x. Then 4 times - 2 is - 8 put that all together you'll get x^+ 2+2x-8
