Y = x – 6 x = –4 what is the solution to the system of equations? (–8, –4) (–4, –8) (–4, 4) (4, –4

2 answers:

8 0

Y = x - 6
x = -4

plug in the second equation in to the first

y = -4 - 6
y = -1(4 + 6)
y = -1(10)
y = -10

The solution to the system is not listed in the options. The correct solution is (-4, -10).

What is the volume of a square pyramid that is 15 cm tall and has a base area of 16 square centimeters?

AlladinOne [14]

Answer:

The volume of the square pyramid is $80\ cm^{3}$

Step-by-step explanation:

we know that

The volume of a pyramid is equal to

$V=\frac{1}{3}Bh$

where

B is the area of the base of pyramid

h is the height of the pyramid

in this problem we have

$B=16\ cm^{2}$

$h=15\ cm^{2}$

substitute the values

$V=\frac{1}{3}(16)(15)=80\ cm^{3}$

Hailey is scuba diving in the ocean. Her boat is anchored 300 feet away at a 30° angle of depression. If her diving partner is 2

Marianna [84]

Answer:

the answer is actually 313 ft not a single person has answered the correct answer... smh

Explanation:

313 ft

sinΘ = opp/hyp

Hailey's depth: x = 300sin30 = 150

partner's depth = 150 + 25 = 175

then, find horizontal distance

300^2 = 150^2 + b^2

b = 150 x square root of 3

then,

c^2 = (150 x square root of 3)^2 + (175)^2

c = 313.25

This is 15 points for whoever answers.

zalisa [80]

Answer:

Y = 40

Step-by-step explanation:

First, find the slope-intercept of the table

Slope-intercept form: y = mx + b

$m=\frac{y_2-y_1}{x_2-x_1}$

(3, 1) and (6,2)

$m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{2-1}{6-3}\\\\m=\frac{1}{3}$

$y=mx+b$

$y=\frac{1}{3}x+b$

Find b using (6,2):

$y=\frac{1}{3}x+b\\\\2=\frac{1}{3}(6)+b\\\\2=\frac{6}{3}+b\\\\2=2+b\\\\-2\ -2\\\\0=b$

$y=\frac{1}{3}x+b== > y=\frac{1}{3}x+0== > y=\frac{1}{3}x$

$y=\frac{1}{3}x$

What will be the value of Y when X = 120?

Substitute 120 for x into $y=\frac{1}{3}x$

$y=\frac{1}{3}x\\\\y=\frac{1}{3}(120)\\\\y=\frac{120}{3}\\\\y=40$

(120, 40)

Therefore, when X = 120, Y = 40

Hope this helps!
