Answer:
The value of a is "3", to complete the coordinate point (3,7) on the line.
Step-by-step explanation:
We are given the slope of the line, and also one point through which the line passes. Therefore, we can find the actual equation of the line by using the slope-point form of the line:
Now, we need to find which value of "x" renders a y-value of "7", to complete the coordinate pair (a, 7) as requested. Therefore, we ask for the y-value in the previous equation to be "7", and solve for its associated x-value:
Therefore, x = 3
Answer:
y=7/5x+7
Step-by-step explanation:
Use the saying "rise over run" to find the slope. If we go from the bottom most dot, we have to rise 7 and run 5 to reach the next dot, making the slope 7/5.
Next, we have to find the y-intercept. Do this by locating where the line crosses the y-axis, in this case it is at 7.
Finally, plug these numbers into slope-intercept format: y=mx+b (m is slope, and b is y-intercept).
Answer:
its the first one

Ive had this question before
Answer:
1 + 3sinA + 3sin²A + sin³A
Step-by-step explanation:
Given
(1 + sinA)(1 + sinA)(1 + sinA) ← expand the last pair using FOIL
= (1 + sinA)(1 + 2sinA + sin²A) ← distribute
= 1 + 2sinA + sin²A + sinA + 2sin²A + sin³A ← collect like terms
= 1 + 3sinA + 3sin²A + sin³A
