For this case we have the following system of equations:
2x-4y = -6
3x + 2y = -1
Step 1:
We rewrite equation 2:
2x-4y = -6
6x + 4y = -2
Step 2:
We add both equations:
8x = -8
Step 3:
We clear x:
x = -8/8
x = -1
Step 4:
We use any equation and we clear y:
3x + 2y = -1
2y = -1-3x
y = -1 / 2 - (3/2) * x
y = -1 / 2 - (3/2) * (- 1)
y = -1 / 2 + (3/2)
y = 2/2
y = 1
Answer:
x = -1
y = 1

Step-by-step explanation:
The data plots represent the hours students study each week in two different classrooms.
The mean number of hours a student in Mr. Hart’s class studies is <em>4.6</em> hours.
The mean number of hours a student in Ms. Perry’s class studies is <em>2.8</em> hours.
A typical student in Mr. Hart’s class studies <em>More Than</em> a typical student in Ms. Perry’s class.

Answer:
Volume of triangular prism = 216 in³
Step-by-step explanation:
Given:
Length of prism = 9 in
Height of prism = 6 in
Base of prism = 8 in
Find:
Volume of triangular prism = ?
Computation:
⇒ Volume of triangular prism = 1/2[lbh]
⇒ Volume of triangular prism = 1/2[9 in × 8 in × 6 in]
⇒ Volume of triangular prism = 1/2[432 in³]
⇒ Volume of triangular prism = 216 in³
