Step-by-step explanation:
1/2(7x+48) = 7x ÷2 +48÷2 = 7x÷2 + 24
and
-(1/2x-3)+4(x+5) = 7x ÷2 + 46÷2 = 7x÷2 +23
2/7 is the answer i think
Try this solution+explanation:
1. the common formula for this graph is y=A*cos(Bx), where A - the amplitude, B - the frequency of the given function.
2. The max. and min. vertical values are 4 and (-4), it means that the amplitude is 4 (A=-4*),
for the function y=cosx the period is 2π, it means for the given function the period is π/2, it is for its frequency 2π/(π/2)=B=4.
* if to see to the suggested graph, the max. of cos4x are in points π/4+πn, and the min. are in π*n/2, it means that it need to add '-' in the equation of the function.
3. answer: y=-4cos4x.
Figure out how far it is from one side to another. The top is 46 + 8 = 55 across.
the bottom is also 55.
Figure out how far it is from the bottom up. The left side is 38 + 10 = 48. The right is also 48.
Put all of the distances together: 55+55+48+48 = ?
Answer:
(1, 5)
Step-by-step explanation:
x is 1 to the right
y is 5 up
