Hello there! I think x=6 because you would substitute “-2” for “-y” and when you multiply two negatives they turn into a positive. You then put your “2” on the other side of the equal marks. Then just do 3x/18 and you get 6.

Identify the slope and y-intercept of the graph of the equation Y=3/4x-2
sukhopar [10]

Hey there! :)

y = 3/4x - 2

To find the slope and y-intercept, simply use slope-intercept form to understand this.

Slope-intercept form is : y = mx + b ; where m = slope, b = y-intercept.

Therefore, you must ask yourself : which value is in the "m" spot and which value is in the "b" spot in our given equation?

Using this logic, we can come to the conclusion that :

Slope = 3/4 & Y-intercept = -2

~Hope I helped! :)

The parabola has a line of symmetry at x=0 so that means we can reflect the function across the y axis and it will remain unchanged so the answer is even function.

After its first day of life, a baby blue whale started growing. It grew 47.075inch. If the average baby blue whale grows at a ra
9966 [12]

Answer:

30 days(To the nearest tenth of a day)

Step-by-step explanation:

In this question, we are asked to give the number of days that a baby whale had grew to a size given the rate at which it grows per day.

We have been told that after the first day, it started growing to a point of 47.075 inch at a rate of 1.5 inch a day.

The number of days taken for this growth can be calculated by dividing the present size by the daily growth rate.

Mathematically, that is 47.075/15 = 31.38333

Now, we are told to convert this to the nearest tenth of a day. The value here should thus be 30.
