Answer:
b = - 0.389
Step-by-step explanation:
38/99=b+17/22
to solve this expression we would make b the subject of the formulae
and evaluate the other parameters.
38/99=b+17/22
collect the like terms
38/99 - 17/22 = b
22( 38) - 99 (17)/ 2178 = b
836 - 1683/2178 = b
-847/2178 = b
b = - 0.389
Answer:
the answer is B
f(x)=-2x+3
Step-by-step explanation:
to get the -2x I did --->
pick two points I used (0,3) and (1,1) and used the equation ![\frac{y2-y1}{x2-x1}](https://tex.z-dn.net/?f=%5Cfrac%7By2-y1%7D%7Bx2-x1%7D)
where y2 would be 1 and y1 would be 3
and where x2 would be 1 and x1 would be 0
so you would put the numbers in the equation which would look like
and equal -2 which would be -2x in the answer
And the +3 is the y-intercept

Answer:
Step-by-step explanation:
Assuming you're interested in the number of each that were sold, the system of equations will express the relation for total sold, and the relation for total revenue. We have used the variable c and p to represent numbers of cakes and pies sold, respectively. Your choices may use x and y, instead.
__
The solution can be found by subtracting 6 times the first equation from the second. That tells you 6 cakes were sold, hence 4 pies.
