Answer: -2x² - 15x + 11
Step-by-step explanation:
Answer:
b+194=pies
Step-by-step explanation:
take the number of pies baked this year then add the b and then you get p(pies)
Peter's meal costed $8.11 in total. Hope this helps :D
So, both equations are essentially linear equations.
Linear equations are written in the format
y = mx+b, where
m represents the
slope/slope intercept and
b represents the
y-intercept.
---------------------------------------------------------------------------------------------------------------
Part Athe slope and y-intercept
y = mx +b
m - the slope; b- y-intercept
therefore;
y = 6x - 4
m = 6; b = -4y = 5x - 3
m = 5; b = -3The coordinates of the point where the lines are crossed are the solution to the system of linear equations.
How to graph the lines:
y = 6x - 4
y-intercept (0; -4)
for x = 1 ⇒ y = 6 · 1 - 4 = 6 - 4 = 2 ⇒ (1; 2)
y = 5x - 3
y-intercept (0; -3)
for x=1 ⇒ y = 5 · 1 - 3 = 5 - 3 = 2 ⇒ (1; 2)
***look at the img for graph reference***Part B:
x = 1; y = 2
If we say that because she bought her materials now she has -50 then she needs to make 215+50=$265 265/17=15,5 so she needs to sell 15
But if we dont take into account that she paid $50 beforehand then 215/17=12,6 so she has to sell 13 poems. Hope it helps
