Question 3(Multiple Choice Worth 3 points) (07.04) Ashley solved the exponential equation 3x+1 = 15 and her work is shown below.

What is the first step she did incorrectly? Step 1: log 3x+1 = log15 Step 2: (x + 1)log 3 = log15 Step 3: x + 1 = log 15 over log 3 Step 4: x+1 = 2.708050 over 1.098612 Step 5: x + 1 = 1.418858 Step 6: x = 0.418858 Step 1 Step 2 Step 3 Step 4

She was not supposed to "undistribute" and separate 3x+1 she was supposed to subtract 1 from both sides

Convert 11.75 millimeters to meters
blsea [12.9K]

Hello!

1,000 millimeters make a meter. To convert millimeters to meters, we just divide by 1,000, or move the decimal to the right 3 places.

11.75/1000=0.01175

Therefore, our answer is 0.01175 meters.

I hope this helps!

M<br> (9x + 2)<br> 1<br> (5х – 1)°<br> 740<br> What is mz2?<br> 39°<br> 570<br> ОООО<br> 67°<br> 740
Elodia [21]

Answer:

<h3>           m∠2 = 67°</h3>

Step-by-step explanation:

m║n   ⇒   (9x + 2)° = 74°       {Corresponding Angles}

(9x)° = 72°

 x = 8

Angles: angle corresponding to angle (5x-1)°, angle 74° and angle 2 add to 180° (straight angle)

(5×8 - 1)° + 74° + m∠2 = 180°

39° + 74° + m∠2 = 180°

113° + m∠2 = 180°

m∠2 = 180° - 113°

m∠2 = 67°

PLEASE HELP WILL GIVE 15 POINTS
natka813 [3]

Answer:

Step-by-step explanation:

Hello, when you have an equation like y = ax+b you know that this is a line.

In this example, the function is defined in two different intervals.

For x < 1 this is the line y = 4 + x

and for x>=1 this is the line y = 4 - 2x

At the frontier, x= 1, we have 4+1=5 on one side and 4-2=2 on the other side, we we expect a "jump" in the graph.

Except that "jump"you just have to draw lines, so if you have two points you can draw them right.

For x<1, the line is passing by (-4,0) and (0,4)

And you have to stop for x<1 so the point (1,5) is not on the graph.

for x>=1 the points (1,2) and (2,0) are on the graph and we just have to draw the line.

I attached the graph.

Thanks
