There exists a similarity transformation that maps ABC to A'B'C. The measure ofthe measure of

Answers

Answer:

Step-by-step explanation: For any triangle, the angles add to 180 degrees

A+B+C = 180

68+46+C = 180

114+C = 180

C+114 = 180

C+114-114 = 180-114

C = 66

Angle C is 66 degrees

Angle C' is 66 degrees

The triangles ABC and A'B'C' are similar, so angle C = angle C'

Which equation describes a line perpendicular to y=8x-9 that passes through the point (9,-9)?f. y=8x-81
G.y=-1/8x-63/8

Answers

The answer is G. Perpendicular lines have opposite reciprocal slopes

Solve by the linear combination method (with or without multiplication) 2x+3y= -17, 5x+2y = -4

Answers

2x+3y= -17
5x+2y= -4
You must cancel either the x or y out to solve so i'm going to cancel the x.
-5(2x+3y= -17)
2(5x+2y= -4)
This simplifies to:
-15x -15y=85
15x+4y= -8
The -15x and 15x cancel out leaving you:
-15y=85
4y= -8
You add them top numbers by the bottom and get:
-11y=77
Then divide by -11 to get y by its self.
y= -7
Now that you know what y is just plug it in to either original problem. I will use the second one.
5x + 2(-7) = -4
5x -14 = -4
5x = 10
x = 2
So the answer is (2,-7) or x=2 and y=-7

Answer: (2,-7) or x=2 and y=-7

Step-by-step explanation: Took the test and can confirm this is the answer!

Solve. -1/8c=2
a. 4
b. –16
c. –4
d. 16

Answers

$(-1)/(8c) =2$
This requires that c ≠ 0 , meaning c≠0
$(-1)/(8c) =2$
Multiply by x to eliminate var in denominator
$( \not c*(-1))/( 8 \not c) =c*2$
$(-1)/(8) =c*2$
Common denominator is 8
$(\not 8(-1))/(\not 8) =8c*2$
$-1=8c*2$
$-1=16c$
$x=-16$
The answer is: b. -16
