Could someone please help me :<br> Simplify the algebraic expression: 10p - 5c + 2p + 8c
Roman55 [17]
10p - 5c + 2p + 8c

= 10p + 2p - 5c + 8c

= (10+2)p + (-5+8)c

= 12p + (8-5)c

= 12p + 3c

Lianne charged twice as much to walk a large dog than she did to walk a small dog. This week she had time to was 10 small dogs a
guapka [62]
Well she charged twice as much to walk large then small. Let s be small and l be large.
We we know that
l = 2s

we also know that she wants to make 100 so
xl + ys = 100

Where where x is number of large and y is number of small. it says she walked 10 small and 5 large so
5l + 10s = 100

substitute 2s for l because they are same value as shown in first equation I made
5 (2s) + 10s = 100
10s + 10s = 100
20s = 100
s = 5

we can now solve for l
l = 2s
l = 2 * 5
l = 10

So s is 5 and l is 10.

What are the slope and y-intercept of the graph of this equation?
schepotkina [342]

Answer:

slope = y = 1/2

y-intercept = b = -3

Step-by-step explanation:

slope intercept equation:

y = mx + b----->(equation 1)

m is slope

b is y-intercept

y = 1/2x - 3----->(equation 2)

Compare (equation 1) and (equation 1)

slope = y = 1/2

y-intercept = b = -3
