I could only answer 14. and it is 138.3
Answer:
y = -2x - 5
Step-by-step explanation:
Let the equation if the line be y = mx + c
since the line is parallel to y = -2x - 8, their gradients/slope must be the same (aka m = -2)
sub (-4, 3):
3 = -2(-4) + c
c = -5
therefore, the equation of the line is y = -2x - 5

Answer: The Martinex family spent $ 82 for train ride and play tickets.
Step-by-step explanation:
Round trip train cost = $ 8.00
For children it cost $ 4.00.
For adult, ticket for play costs= $ 14.00
For children , ticket for play costs= $ 6.00
Mr. And Mrs. Martinez will go with their children, Ricky, Ramona, and Thomas.
2 adults and 3 children ( only one of them is under 7.)
For train we consider only 1 as child rest as adult.
Train cost = 4 x($ 8.00)+ 1 x ($ 4.00)
= $ 32+4 = $36
For play , total cost = 2 x ( $ 14.00) + 3 x ($6)
= $(28+18)
= $ 46
Total spending ( combined) = $36+$ 46
= $82
So, the Martinex family spent $ 82 for train ride and play tickets.
The Type B trees produces 120 pears.
<h3>What is meant by percentage?</h3>
A percentage is a number or ratio expressed as a fraction of 100 in mathematics. The percent sign, "%," is commonly used, but the abbreviations "pct.", "pct," and sometimes "pc" are also used. A percentage is a number with no dimensions; it has no unit of measurement.
<h3>
How many pears did the Type B trees produce?</h3>
- Type A trees produced 20 percent more pears than Type B trees did
- Type A trees produced 144 pears.
Let us consider, Type B produced 100% pears.
So, Type A will produce 120%of B, that is 144
144 = 120/100 
B
simplifying the above equation, we get
144 100 = 120B
B = 14400/120
B = 120
The value of B = 120.
Hence, the Type B trees produces 120 pears
Therefore, the correct answer is option B) 120.
