y= 1
2x - 5 = -1
2x = 4
x = 2
(2, 1)
2b. 4x + 2y = 4
x - 2y = -5
5x = -1
x= -1/5
-1/5 - 2y = -5
-2y = -4 4/5
y= 12/5
(-1/5, 12/5)
3. 5x + 3y = 85
11x + 5y = 163
25x + 15y = 425
-33x - 15y = -489
-8x = -64
x = 8 regular
5(8) + 3y = 85
40 + 3y = 85
3y = 45
y = 15 mini bouquets
(8 regular, 15 mini bouquets)
4a. 6x + 12y = -6
18x - 12y = - 162
24x = -168
x = -7
3(-7) - 2y = -27
-21 - 2y = -27
-2y = -6
y= 3
(-7, 3)
4b. 3(6 -y) - 2y = 38
18 - 3y - 2y = 38
18 - 5y = 38
-5y = 20
y = -4
x = 6 + 4
x = 10
(10, -4)

C. 57.59
D. 22.50
Answers
Answer:
A. 45°
Step-by-step explanation:
By exterior angle theorem:
x + 70° = 115°
x = 115° - 70°
x = 45°
Answer:
x= 45°
Step-by-step explanation:
triangles degrees all together are always 180°
x≠180°
a straight line is also 180°
180°-115°= 65°
70°+65°= 135°
180°-135°= 45°

23. Describe the slopes of perpendicular lines
Answers
Answer:
The slopes of two perpendicular lines are negative reciprocals of each other. This means that if a line is perpendicular to a line that has slope m, then the slope of the line is -1 / m. For example, we found that the slope of the line y = (1/2)x + 3 is 1/2.
The slopes of perpendicular lines when multiplied together gives the product as -1.
What is the slope of straight line?The slope of a straight line is the tangent of the angle formed by it with the positive x axis as the reference.
The negative slope indicates the rate of decrease while the positive shows the rate of increase.
Suppose the two perpendicular lines have equations as follows,
y = m₁x + c₁ and y = m₂x + c₂.
Suppose m₁ = tan θ
Then, m₂ = tan (90° + θ)
Apply the trigonometric identity to obtain,
m₂ = tan (90° + θ) = -cot θ
Now, m₁ × m₂ = tan θ × -cot θ = -1
Thus, the products of slopes is -1.
Hence, the product of slopes of two perpendicular lines is -1.

Two planes leave an airport at the same time, one flying east, the other flying west. The eastbound plane travels 130 mph slower. They are 3850 mi apart after 5 hr. Find the speed of each plane.
Answers
Answer:
Speed of the slower plane = 320 mph
Speed of the faster plane = 450 mph
Step-by-step explanation:
Let the speed of the slower plane = x mph
And the speed of the faster plane = y mph
Difference in their speeds = 130 mph
y - x = 130 --------(1)
Formula for the distance traveled = Speed × time
Distance traveled by the faster plane in 5 hours = 5y miles
Distance traveled by the slower plane in 5 hours = 5x miles
Total distance traveled by both the planes in 5 hours = 5(x + y) miles
5(x + y) = 3850
x + y = 770 ---------(2)
By adding equations (1) and (2)
2y = 900
y = 450 mph
From equation (2)
x = 770 - 450
x = 320 mph
