Answer:

\boxed{z = -7}

Step-by-step explanation:

=  >  - 9 + 8(14z  + 2) = 7(17z + 8) \\  \\  =  >  - 9 + (8 \times 14z + 8 \times 2) = (7 \times 17z) + (7 \times 8) \\  \\  =  >  - 9 + 112z + 16 = 119z + 56 \\  \\  =  >  7 + 112z = 119z + 56\\  \\  =  >  7 + 112z - 119z = 56 \\  \\  =  >   7 - 7z = 56 \\  \\  =  >  - 7z = 56 - 7 \\  \\  =  >  - 7z = 49 \\  \\  =  > 7z =  - 49 \\  \\  =  > z =  -  \frac{49}{7}  \\  \\  =  > z =  - 7

Answer:

z=-7

Step-by-step explanation:

-9+8*14z+8*2=7*17z+7*8

-9+112z+16=119z+56

112z+7=119z+56

-112z       -112z

7=7z+56

-56    -56

-49=7z

:7     :7

z=-7

What is the image point of (-6, 9) after a translation left 4 uints and down 1 unit?
Alex17521 [72]

Answer:

(-10,8)

Step-by-step explanation:

So our original point is (-6,9).

A translation of 4 units to the left means that the x-value would go left by 4. In other words, we subtract 4 to -6. We subtract because going to the left means that it's going to the negative direction.

A translation of down 1 unit means that the y-value would go down by 1. In other words, we subtract 1. Again, we subtract because going downwards means that it's going to the negative direction.

Therefore, the new point would be:

(-6-4,9-1)\\=(-10,8)

Can anyone help me please
Sauron [17]

Range of values of x is 25°<x<27°.

<u>Step-by-step explanation:</u>

An angle is formed when two rays, a line with one endpoint, meet at one point called a vertex.Alternate interior angles are formed when a transversal passes through two lines. The angles that are formed on opposite sides of the transversal and inside the two lines are alternate interior angles. The Alternate Interior Angles theorem states, if two parallel lines are cut by a transversal, then the pairs of alternate interior angles are congruent.

In above question, sides are equal and so alternate interior angles are equal i.e. 2x + 10° = 62° ⇒ 2x = 52° ⇒ x =26°

∴ range of values of x is 25°<x<27°

Need Help ASAP<br><br> 1.5x+6=2+3x<br> 2.2(6-2y)=-1(4y-9) <br> 3.2z-6=2(z+2)+10
zavuch27 [327]
1. 5x + 6 = 2 + 3x
-3x. - 3x
-------------------------
2x + 6 = 2
- 6. - 6
-------------------------
2x = -4
---- -----
2. 2

x = -2

2. 2(6 -2y) = -1(4y-9)
12 -4y = -4y + 9
+4y. +4y
----------------------------
.12 /=\ 9
No solution

3. 2z-6 = 2(z+2) + 10
2z -6 = 2z + 4 + 10
2z -6 = 2z +14
-2z. -2z
-6 /=\ 14
