Answer:
B) 4y+8
D) y+y + y + y + 2 + 2 + 2 + 2*
Step-by-step explanation:
The expressions equivalent to 4(y + 2) are given below:
- B) 4y+8
- D) y+y + y + y + 2 + 2 + 2 + 2
Answer:
Step-by-step explanation:
The value of y is given in equation 2
Putting value of y = 3x in equation 1
Y = - x + 4
3x = - x + 4
Bringing like terms on one side
3x + x = 4
4x = 4
x = 4/4 = 1
Now putting value of x = 1 in equation 2
Y = 3x
Y = 3(1) = 3

Remark
The point value is (-2,5) So we know the two sides. We need the hypotenuse. We should notice that the x value is minus (-2) and value is y value is plus (5). That means we are in quad 2. Be careful how you read that. (-2,5) is a point. It is not a tangent.
Step One
Find the hypotenuse.
a = - 2
b = 5
c = ??
c^2 = a^2 + b^2
c^2 = (-2)^2 + 5^2
c^2 = 4 + 25
c^2 = 29 Take the square root of both sides.
sqrt(c^2) = sqrt(29)
c = sqrt(29)
Step Two
Find the Cosine of the angle.
Cosine(theta) = adjacent / hypotenuse
Cosine(theta) = -2 / sqrt(29) <<<<<<< Answer
Again, watch out for what you are given.
Brennon should make about $212.05. since 153/18 is 8.5, all we do is multiply 8.5 by 25. that gives us 212.5, convert it to money and you get $212.05.
