Answer:
y = -3
Step-by-step explanation:
{y = x/2 - 4
y = 1 - 2 x
Substitute y = x/2 - 4 into the second equation:
{y = x/2 - 4
x/2 - 4 = 1 - 2 x
In the second equation, look to solve for x:
{y = x/2 - 4
x/2 - 4 = 1 - 2 x
Add 2 x + 4 to both sides:
{y = x/2 - 4
(5 x)/2 = 5
Multiply both sides by 2/5:
{y = x/2 - 4
x = 2
Substitute x = 2 into the first equation:
{y = -3
x = 2

Answer:
{x = 2
y = -3
Answer:
27
Step-by-step explanation:
he started by cutting one log into 3
1×3=3
then cutting each of those into 3
3×3=9
then again
9×3=27
Answer:
The first one (A) is the answer I got!
Step-by-step explanation:
Answer:
(13, -3)
Step-by-step explanation:
slope = -5/7
(6,2)
m = ( y2 - y1) / ( x2 - x1 )
-5/7 = ( y2 - 2) / ( x2 - 6 )
-5 = y2 -2
+2 +2
-3 = y2
7 = x2 - 6
+6 +6
13 = x2
Check answer again by log them in:
m = ( y2 - y1 ) / ( x2 - x1 )
m = ( -3 - 2 ) / ( 13 - 6 )
m = -5 / 7
I hope this helps!
For this case we have the following multiplication:
We can rewrite this multiplication in the following way:
From here, we apply the distributive property.
We have then:
Therefore, Jack's strategy is:
Write the number in an expanded form and then apply the distributive property.
