In the second one I'm pretty sure you just measure the length of the points.
The answer is C.
x=2
y=-30
(2;-30)
Answer: y= 4/3x + 19/3
Step-by-step explanation: See the attachment below! Sorry, my handwriting is bad on computer, I've also attached notes to this lesson for you!!!
The time that will be taken for Daniel to swim to the boat ramp will be 3.34 minutes.
<h3>How to calculate time taken</h3>
Let the distance be x.
Based on the information given, the calculation will be:
Sin 53° = 400/x
0.7986 = 400/x
x = 500 feet
Time = Distance / Speed
Time = 500/150 = 3.33 minutes.
The distance of the boat ramp from the campsite will be:
Cos53° = y/500
0.60 = y/500
y = 300 feet.
Distance will be:
= 1600 - 300 = 1300 feet
The minutes that it takes him to jog from the boat ramp to the campsite will be:
Distance = 1300 feet
Rate = 4 miles per hour = 352 feet per minutes
Time = Distance / Rate
Time = 1300/352 = 3.69 minutes
The total time taken will be:
= 3.33 + 3.69
= 7.02 minutes

Answer:
D. There is no mistake.
Step-by-step explanation:
The following lines show the process of factorization by using common factor.
<u>Line 1:</u>
In line 1, the equation is given and is completely fine.
The only thing missing was equate to zero, but the options below talk about correct factors only, therefore this can't be considered as a mistake and can be ignored completely.
<u>Line 2:</u>
In line 2, the terms are grouped, from which we can factor out common terms.
This is also fine.
<u>Line 3:</u>
In line 3, the common term y is taken out from group 1 and 2 from other group.
which is exactly what is given in line 3.
<u>Line 4:</u>
In line 4 the common factors can be seen and easily split into 2 factors.
which is exactly what is given in line 4.
Options:
A. The grouping is correct in line 2. So this option is does not hold.
B. Common factor was factored correctly from group 1. So this option does not hold.
C. Common factor was factored correctly from group 2. So this option does not hold.
D. There is no mistake. This is correct. Thus we choose this option as correct answer.
