Answer:
-4 or -4/1
Step-by-step explanation:
The equation is in y=mx+b form
m is the slope, and b is the y intercept
So, for this line, y=-4x+10
-4 is the slope and 10 is the y intercept
Hope this helps! :)
Answer:
<em>2(8-8x)</em>
Step-by-step explanation:
Distrubutive Property:
↓
A(B+C)=AB+AC
<em>Multiply by the numbers from left to right.</em>
4*2=8
<em>Therefore the correct answer is </em><em>2(8-8x).</em>

Answer:
Vertical : Angles 1 & 4 Supplementary: 5 & 6
Step-by-step explanation:
Vertical angels are angles that have the same measure that are opposites of each other (1 & 4) and supplementary angles are 2 angles that equal 180 degrees that are right next to each other or right above each other (5 & 6) (3 & 5)
Answer:
Step-by-step explanation:So we know x + y = 21 and 5x +10y = 165 We line them up in columns x + y = 21 5x +10y = 165 To eliminate the x variable, I'll multiply every element in the 1st equation by -5. -5x + -5y = -105 5x + 10y = 165 Now we combine (add) the equations, which eliminates x altogether. 5y = 60 ... y = 12 From there, x + 12 = 21 ... x = 21-12 ... x = 9 You should double check. Do 9 nickles and 12 dimes equal $1.65? A very important thing to remember using this method is to do the same thing to each element in the equation that you change! I hope that helps.
