1. Line a passes through (-2, 3) and (1. -1). 2. Line & y = --4x + 7
Line b passes through (-3, 1) and (1. 4). Line b: x = 4y + 2
Line c passes through (0, 2) and (3, -2). Linee - 4y + r = 3
HELP PLEASE
9514 1404 393
Answer:
1. line b is perpendicular to the other two, which are parallel
2. line a is perpendicular to the other two, which are parallel
Step-by-step explanation:
1. The differences between coordinates (∆x, ∆y) are ...
(-2, 3) -(1, -1) = (-3, 4) . . . line a
(-3, 1) -(1, 4) = (-4, -3) . . . line b
(0, 2) -(3, -2) = (-3, 4) . . . line c
When the (∆x, ∆y) values are identical, the lines are parallel. If the values are swapped, and one differs in sign, the lines are perpendicular.
line b is perpendicular to lines a and b, which are parallel
__
2. When all of the equations are written in standard form, they are ...
4x +y = 7 . . . line ax -4y = 2 . . . line bx -4y = 3 . . . line cAs above, when the x- and y-coefficients are identical, the lines are parallel. If they are swapped and one is negated, the lines are perpendicular.
line a is perpendicular to lines b and c, which are parallel

There are 160 boys and gitls playing in soccer tournament. 32 of the students are wearing Orange. What percent of yhe players are wearing orange
Answer:
20 percent
Step-by-step explanation:
Because there are 160 total people, you would divide 32 by 160 which gives you 0.2 multiply 0.2 by 100 then you get 20 percent
32/160 = 0.2
0.2*100 = 20
Answer:
53.3%
Step-by-step explanation:
(32/63)×100
=53.3%
9) A basic cell phone plan at Verizon Wireless costs $45 a month with an additional $0.10 per text message sent. AT&T charges $30 a month with an additional $0.13 per text message sent. How many text messages would you have to send for the plans to cost the same? If you send an average of 1200 text messages a month, which company would you want to choose as your provider?
a. Define your variables &Write your system of equations
b. Use your equations to solve. Make sure you label your answer
Number of tests made =x
Verzon C(x) = 45 + 0.1x => 45+0.1*1200 =165
AT & T C(y) = 30 + 0.13x=> 30 + 0.13*1200=186
For 1200 texts C(x) is less than C(y)
If the costs are to be the same then
45 + 0.1x = 30 + 0.13x
15=0.03x
15/0.03= x
500=x

and (6, 80) from the line on the scatter plot. What is the equation of the trend line? Drag numbers to complete the
equation Numbers may be used once, more than once, or not at all
Answer:
y= 3x+62
Step-by-step explanation:
m= y₂-y₁/x₂-x₁
m= 80-62/6-0
m= 18/6
m=3
y-y₁=m(x-x₁)
y-62= 3(x-0)
y-62= 3x-0
y= 3x+62
12. The point P lies on a line through the midpoint of AB and perpendicular to AB. If AP=15 in., what is the length PB? How do you know?
Answer:
PB = 15
Step-by-step explanation:
A midpoint is a point in the center of a line. Since P is the midpoint of AB, the length of AP = PB. Therefore, if AP = 15, PB = 15.

Commutative property of multiplication
pls mark me brainiest
Step-by-step explanation:
Answer: The Commutative Property of Multiplication
Step-by-step explanation: The commutative property of multiplication states that when two numbers are being multiplied, their order can be changed without affecting the product. In this case, changing the order of 16 and 2, doesn’t matter because they will always be equivalent to each other.

Answer:
8. 504ft²
9. 4970yd² (rounded to 3 s.f.)
Formulas (For easy reference):
Area of rectangle = length × breadth
Area of circle = pi×r×r
Circumference of circle = pi×r×2
-----------------------------------------------------------------------------------------------------------
Step-by-step explanation:
8. You know a box has 6 sides, and there are 3 types of surfaces that are different from each other, and you have to multiply each side by 2 cus there are the front and backside (You can draw the box with its dimensions to see the 3 types of surfaces and why I multiplied by 2):
(2×12×6) + (2×12×10) + (2×6×10) = 144 + 240 + 120
= 504ft²
9. The net of a cylinder contains two circles of radius 24yd and one long sheet to wrap around the circles with the length that is the circumference of the circle (so that it can wrap around the two circles) and a width which is the height of the cylinder (9yd).
2 Circles = 2×pi×24×24
= 1152pi
Long sheet = 9×24×2×pi
= 432pi
Now we can add all of them together:
432pi+1152pi = 1584pi
= 4970yd² (rounded to 3 s.f.)
Answer:
Step-by-step explanation:
9.) Surface Area of Cylinders: A=2πrh+2πr^2
A=2πrh+2πr^2
A=2(3.14)(12)(9)+2(3.14)(12)^2
A = 678.24 + 904.32
A ≈ 1582.56

Two different buses start their routes at the same corner at 9 A.M. Buses from one route stop at the library every 9 minutes. Buses from the other route stop at the library every 12 minutes. In what number of minutes will both buses end up at the library?
Answer: In 36 minutes both buses will end up at the library.
Step-by-step explanation:
Given: Buses from one route stop at the library every 9 minutes.
Buses from the other route stop at the library every 12 minutes.
The number of minutes in which both buses will end up at the library= LCM(9,12)
Now , 9= 3 x 3
12= 2 x 2 x 3
LCM(9,12) = 2 x 2 x 3 x 3 = 36
In 36 minutes both buses will end up at the library.

The range of lengths the third piece of wood would be 3 < x < 37 .
Using triangle inequality theorems, which states that the sum of two side lengths of a triangle is always greater than the third side.
Therefore,
A triangle with sides x, y and z will be as follows;
x + y > z
x + z > y
y + z > x
Therefore, for the woods to form a triangular piece. The third length will be in the range 4 inches to 36 inches.
Let's text the rules for the end points
20 inches + 17 inches > 4 inches
20 inches + 4 inches > 17 inches
17 inches + 4 inches > 20 inches
20 inches + 17 inches > 36 inches
20 inches + 36 inches > 17 inches
17 inches + 36 inches > 20 inches
Therefore, the range of length for the third piece of wood would be
3 < x < 37
