How is the product of 3 and –2 shown using integer tiles?
2 answers:
Answer:
-6
Step-by-step explanation:
Solution :
Since we are given that 3 * -2
SInce 2 has negative sign so will make groups of two negative signs
Since 3 is positive so we will make 3 groups of 2 negative signs (refer the attached figure)
So, there are three groups of two negative signs so there will be 6 negative signs.
Thus the answer will be -6

Answer:
OPTION A: 2x + 3y = 5
Step-by-step explanation:
The product of slopes of two perpendicular lines is -1.
We rewrite the given equation as follows:
2y = 3x + 2
⇒ y =
The general equation of the line is: y = mx + c, where 'm' is the slope of the line.
Here, m = .
Therefore, the slope of the line perpendicular to the line given = because
.
To determine the equation of the line passing through the given point and a slope we use the Slope - One - point formula which is:
y - y₁ = m(x - x₁)
The point is: (x₁, y₁) = (-2, 3)
Therefore, the equation is:
y - 3 = (x + 2) $
⇒ 3y - 9 = -2(x + 2)
⇒ 3y - 9 = -2x - 4
⇒ 2x + 3y = 5 is the required equation.
