Step-by-step explanation:
-2x - 6xy - 3y + 7x <em>combine like terms</em>
= (-2x + 7x) - 6xy - 3y
= 5x - 6xy - 3y
Answer:
t
Step-by-step explanation:
<h3>Solution and Explanation:</h3>
If 
and 
are directly proportional, then they must have a common scalar.
To find we must first find its scalar. If we let 
be the scalar we can form the equation, 
.
We are given the information that if 
then 
. We can use that in finding the scalar.
Now we can solve for when 
knowing that our scalar is 
.
<h3>Answer:</h3>
when
Answer:
y = 3/5x + 3
Step-by-step explanation:
→ Write down in y = mx + c
y = 3/5x + c
→ Substitute in coordinates
0 = -3 + c
→ Find c
c = 3
→ Rewrite
y = 3/5x + 3
Answer and Step-by-step explanation:
-2 + 23x is an angle, and since the angles are all 90 degrees (shown with the red square), -2 + 23x = 90
Solve for x.
-2 + 23x = 90
Add 2 to both sides.
23x = 92
Now divide by 23 on both sides to obtain x.
x = 4
x is equal to 4.
