Two lines intersect to form a linear pair with equal measures. One angle has the measure 3x° and the other angle has the measure

(9y − 18)°. Find the values of x and y.

3x + 9y - 18 = 180

3x = 9y - 18

Which means

3x = 90

9y - 18 = 90

Solving for each:

x = 90/ 3

x = 30

And

9y = 108

y = 108/9

y = 12

Answer: x = 30 , y = 12

A) The intersection occurs at the same height 'y', so the y of each equation must be equal:

y=y implies <span>2−x = 8x+4. The solution is -2=9x, x = -2/9=2/3, and y = 20/9

(-2/9,20/9)

B)
X    |   Y1   | Y2
_____________
-3   5    -20
-2   4    -12
-1   3    -4
0    2   4
1 1 12
2    0   20
3   -1 28

C) I would draw each line with the values on the table. Where both lines cross is the intersection point. It should be (-2/9, 20/9)

Al and Bill each have two bullets. They fire alternately at a glass bottle. Al has hitting probability 1/3 and Bill 1/4. What is

enot [183]

P(Al hits bottle first time) = 1/3
P(Al misses the first shot but hits on his second shot) =
P( Al misses and bill misses and Al hits) = 2/3 * 3/4 * 1/3 = 1/6

So required probability = 1/3 + 1/6 = 1/2

Which shows the image of quadrilateral ABCD after the transformation R0, 90°?

avanturin [10]

Answer:

A'(0,-1), B'(1,0) , C'(3,-2), and D'(2,-3)

Step-by-step explanation:

The coordinates of rectangle ABCD are A(-1,0), B(0,-1), C(-2,-3), (-3,-2).

The mapping for a rotation through 90° clockwise about the origin is

$(x,y)\to ( - y,x)$

Therefore:

$A(-1,0)\to A'(0,-1)$

$B(0,-1)\to B'(1,0)$

$C(-2,-3)\to C'(3,-2)$

$D(-3,-2)\to D'(2,-3)$

Therefore the image rectangle has coordinates:

A'(0,-1), B'(1,0) , C'(3,-2), and D'(2,-3)

The first choice is correct.

F(x)= x-7 when x= -2

lesya692 [45]

F(x) = x - 7
x = -2

f(-2) = -2 - 7
f(-2) = -9
