The information given about the proof does that Daniel made an error on line 2.

<h3>How to illustrate the information?</h3>

Given:

1. AB = 3x +2;  BC = 4x + 8;  AC = 38

2. AB + BC = AC      incorrect (not an angle angle addition postulate)

3. 3x+2 + 4x + 8 = 38         correct

4. 7x + 10 = 38                    correct

5. 7x = 28                           correct

6. x = 4

Daniel made an error on line 2.

Here is the complete question:

Y=-3/2x+5 y=-3/2x-3 how many solutions
Mademuasel [1]

Answer:

No Solution

Step-by-step explanation:

If two lines have the same slope and different y-intercepts, that means there is no solution. If the y-intercept and the slope are the same, it will have infinite solutions... So because these have the same slope, but different y-intercepts, they won't have any solution.

!solve this!<br> 3x + 70 − 7x ≥ 18
UNO [17]

Answer:

3x + 70 − 7x ≥ 18

Step 1: Simplify both sides of the inequality.

−4x + 70 ≥ 18

Step 2: Subtract 70 from both sides.

−4x + 70 − 70 ≥ 18 − 70

−4x ≥ −52

Step 3: Divide both sides by -4.

−4x /−4  ≥  −52 /−4

x ≤ 13

tresset_1 [31]

Answer:

170

Step-by-step explanation:

The angle 42x+1 is the inscribed angle of Arc WX. This means Arc WX is twice of 42x+1.

wx = 2(42x + 1)

We can add up that and the other arcs to 360.

2(42x + 1) + 29x - 1 + 65x + 3

84x + 2 + 29x - 1 + 65x + 3 = 360

178x + 4 = 360

178x = 356

x = 2

Plug in 2 for WX.

84(2) + 2 = 170
