HELP PLEASE, ITS DUE TODAY IN AN HOUR!!

Schach [20]

Answer:

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

If m > 0 , then line slopes upwards from left to right

If m < 0 , then line slopes downwards from left to right

y = 3x - 2

has m > 0 and c = - 2 , thus line slopes upwards crossing the y- axis at - 2

y = - 2x + 3

has m < 0 and c = 3, thus line slopes downwards crossing the y- axis at 3

on the graph this is the lower blue line and the red line

the solution to the system is at the point of intersection of the 2 lines

This is at point D

The radius of the base of a sugar cone is 1.5 inches and the cone is 8 inches tall.

g100num [7]

Answer:

about 18.85 cubic inches of ice cream can fit inside the cone

Step-by-step explanation:

To understand this, you will need to know the formula for a cone's volume which is

πr^2 times h/3

h being the height of the cone

to clarify the equation is pi (3.14) times the radius squared (which means you put it to the power of 2) and you multiply it by the height divided by 3.

Step by step:

π(1.5)^2 times 8/3

put it in a calculator and solve

round according to the problem

Square root of 32 x square root of 1 over 18

lisov135 [29]

<h3>Solution:</h3>

$\sqrt{32} \times \sqrt{ \frac{1}{18} } \\ = \sqrt{32} \times \frac{ \sqrt{1} }{ \sqrt{18} } \\ = \sqrt{32} \times \frac{1}{ \sqrt{18} } \\ = \frac{\sqrt{2 \times 2 \times 2 \times 2 \times 2}}{ \sqrt{2 \times 3 \times 3} } \\ = \frac{ \sqrt{ {2}^{2} \times {2}^{2} \times 2} }{ \sqrt{2 \times {3}^{2} } } \\ = \frac{2 \times 2 \times \sqrt{2} }{3 \times \sqrt{2} } \\ = \frac{4 \times \sqrt{2} }{3 \times \sqrt{2} } \\ = \frac{4}{3}$

<h3>Answer:</h3>

$\frac{4}{3}$
