Jolon used the slope-intercept form to write the equation of a line with slope 3 that passes through the point (5, –2). His work

is shown below.
Step 1: Negative 2 = 3 (5) + b
Step 2: negative 2 = 15 + b
Step 3: Negative 2 + 15 = 15 + 15 + b
Step 4: Negative 13 = b
Step 5: y = 3x – 13

Analyze the steps. In which step did the Jolon make an error?
He switched the x- and y- values in step 1.
He multiplied incorrectly in step 2.
He added 15 to both sides in step 3.
He forgot to add the b-value in step 5.

Answer.
Jolon’s mistake was that he added 15 to both sides in step 3.

Explanation:
To cancel something out on one side of the equation, we would do the opposite of what it’s sign is. If it’s positive, we subtract. If it’s negative, we add.

In Jolon’s case here, 15 was positive, which means the correct thing to do is to subtract 15 from both sides. He added instead, which was incorrect.

I hope this helps! Please comment if you have any questions.

LiRa [457]

Answer:

3.5^{2} = 3.5 * 3.5 = 12

square means: multiply the number <u>by itself</u> two times. so 3.5 * 3.5

cube (3.5^{3}) means: multiply the number by itself three times. so 3.5 * 3.5 * 3.5

i hope u understand :)

The number 321.8 is 34% of x. What is the value of x rounded to the nearest whole number?
Anni [7]

Answer:

946

Step-by-step explanation:

Let's make an equation :

34% of x = 321.8

Covert 34% into decimal by dividing by 100 :

34 ÷ 100 = 0.34

Rewrite equation with decimal form :

0.34x = 321.8

Divide both sides by x to make x the subject :

x = 321.8 ÷0.34

x = 946.470588235

To the nearest whole number will be 946 as 4 rounds it down

So our final answer will be 946

Hope this helped and have a good day

About when does the softball reach its maximum height?
Masja [62]

Based on the given graph, the time when the softball reaches its maximum height is about 1.8 seconds.

<h3>When is the softball at it highest?</h3>

The softball is at its maximum height at the point where the curve begins to go back down.

This means the maximum height is 50 feet.

The time when this softball reaches this height is between 1 and 2 seconds at 0.8.

The time the softball reaches its maximum height is therefore 1.8 seconds.
