Question 1)
Given
The expression is 5xy
To determine
Find the value of 5xy if x = 2 and y = 3
5xy
substitute x = 2 and y = 3
5xy = 5(2)(3)
= 5(6)
= 30
Therefore, the value of 5xy = 30 if x = 2 and y = 3.
<em>Note: your remaining questions are not mentioned. But, the procedure may remain the same. Hopefully, your concept will be cleared anyway.</em>
To solve this problem, you must follow the proccedure below:
1. T<span>he block was cube-shaped with side lengths of 9 inches and to calculate its volume (V1), you must apply the following formula:
V1=s</span>³
<span>
s is the side of the cube (s=9)
2. Therefore, you have:
V1=s</span>³
V1=(9 inches)³
V1=729 inches³
<span>
3. The lengths of the sides of the hole is 3 inches. Therefore, you must calculate its volume (V2) by applying the formula for calculate the volume of a rectangular prism:
V2=LxWxH
L is the length (L=3 inches).
W is the width (W=3 inches).
H is the heigth (H=9 inches).
4. Therefore, you have:
V2=(3 inches)(3 inches)(9 inches)
V2=81 inches
</span><span>
5. The amount of wood that was left after the hole was cut out, is:
</span>
Vt=V1-V2
Vt=648 inches³

Answer:
Given points ( -1 ,3 ) and slope(m) = -3
Step-by-step explanation:
<em>The </em><em>equation </em><em>of </em><em>a </em><em>line </em><em>is </em><em>given </em><em>by </em>
<em>y </em><em>-</em><em> </em><em>y1 </em><em>=</em><em> </em><em>m </em><em>(</em><em> </em><em>x </em><em>-</em><em> </em><em>x1</em><em> </em><em>)</em>
<em>y </em><em>-</em><em> </em><em>3</em><em> </em><em>=</em><em> </em><em>-</em><em>3</em><em> </em><em>(</em><em> </em><em>x </em><em>+</em><em>1</em><em> </em><em>)</em>
<em>y </em><em>-</em><em> </em><em>3</em><em> </em><em>=</em><em> </em><em>-</em><em>3</em><em>x</em><em> </em><em>-</em><em> </em><em>3</em>
<em>3x </em><em>+</em><em> </em><em>y </em><em>-</em><em>3</em><em> </em><em>+</em><em>3</em><em> </em><em>=</em><em>0</em>
