–9x + 10y = –9 whats that in slope intercept form
2 answers:
Answer:
Slope intercept form of the line is y =
Step-by-step explanation:
Equation of a line has been given as -9x + 10y = -9
It's a standard form of the equation and we have to convert it into slope intercept form.
Slope intercept form of the line is in the form of y = mx + c
Where m = slope of the line
c = y-intercept of the line
-9x + 10y = -9
10y = 9x - 9
y =
y =
Therefore, slope intercept form of the line will be y =

Answer:
Step-by-step explanation:
<h3> The missing question is: "What is the Functions formula A(t)=?"</h3><h2 />The equation of the line in Slope-Intercept form is:
Where "m" is the slope and "b" is the y-intercept.
According to the data given in the exercise, you know that:
- represents the area to paint the Hiros' romm as a function of time.
- The rate he painted the room was 8 square meters per hour.
- The area left to paint after 3 hours was 28 m².
Therefore, based on this, you can idenfity that:
1. The slope of the line is:
2. One of the point on the line is:
So you must substitute the slope and the coordinates of that point into and then solve for "b" in order to find its value:
Therefore, you can determine that the function is:
Answer:
C. 40
Step-by-step explanation:
Let us say there are x 7's and y 77's.
We have been given that each term in the sum a1+a2+a3+...+an is either 7 or 77 and the sum equals 350. We are asked to find the value of n.
Since the sum of all numbers is 350, so we can represent this information in an equation as:
The only integer solutions for the equation are 10, 20, 30, 40, 50
.
So, there can be these many terms: 10 or 20 or 30 or 40 or 50 .
The given option only contains 40, so 40 would be the answer. For 40 terms to be there, there has to be 39 sevens and 1 seventy-seven.
Let us verify our answer.
Therefore, the total terms (n) could be equal to 40 and option C is the correct choice.
