−3 (x+5 ) = 9.
-3(x) + -3(5) = 9
-3x -15 = 9
+15 +15
-3x = 24
/-3 -3
x = -8 Hope this helps!
Well, you would need to multiply 6.75 and 21, since there are 21 spools, you then simply subtract the spool used for the project and the is your answer, and don't forget to label
Answer:
B. (2, 0) - True, True, True
Step-by-step explanation:
A. (2, 3) - False
y ≤ 6x - 12 (False)
y ≤ 1/2x + 6 (False)
y ≥ -x - 4 (True)
B. (2, 0) - True, True, True
y ≤ 6x - 12 (True)
y ≤ 1/2x + 6 (True)
y ≥ -x - 4 (True)
C. (-3, 0) - False
y ≤ 6x - 12 (False)
y ≤ 1/2x + 6 (False)
y ≥ -x - 4 (True)
D. (1,1) - False
y ≤ 6x - 12 (False)
y ≤ 1/2x + 6 (False)
y ≥ -x - 4 (True)

<span><u><em>The correct answers are: </em></u>
A) reflection
A) dilation.
<u><em>Explanation: </em></u>
To produce a <u>congruent figure</u>, the angle measures of the image and the side lengths of the image must be the same as the angle measures and side lengths of the pre-image. This means we cannot shrink, expand, or contract the figure; by definition those transformations change the size. This leaves <u>reflection.</u>
To produce a <u>similar, but not congruent, figure</u>, we must change the side lengths while keeping the angle measures preserved. Translations, reflections and rotations will move a figure but do not change the side lengths; <u>dilation</u> is the only choice that will change the side lengths.</span>
Answer:
a=19, b=4, c=22
Step-by-step explanation:
The perimeter of a triangle is found by adding all 3 of the side together.
Side a + Side b + Side c = perimeter.
Use what they gave you for the 3 sides.
(2x + 5) + (x - 3) + (3x + 1) = 45 inches
Now just start simplifying the equation. You can start by adding the whole numbers 5 - 3 + 1 = 3
2x + x + 3x + 3 = 45
Now add the others.
2x + x + 3x = 6x so you have 6x + 3 = 45
Subtract 3 from both sides of the equation
6x = 42
Divide each side by 6
x = 7
So now plug the value of X into the equations your were give for all 3 sides.
Side a = (2x+5) or (2)(7) + 5 = 19
Side b = (x - 3) or (7 - 3) = 4
Side c = (3x + 1) or (3)(7) + 1 = 22
Check you answers by adding the 3 numbers. 19 + 4 + 22 = 45 inches
