Answer:
x² + 4x + 3
Step-by-step explanation:
Given
(x + 1)(x + 3)
Each term in the second factor is multiplied by each term in the first factor, that is
x(x + 3) + 1(x + 3) ← distribute both parenthesis
= x² + 3x + x + 3 ← collect like terms
= x² + 4x + 3
What do you mean? whats the question?
Answer: One possible equation is: y = -0.86x + 67.3, that would make the temperature in Panama City 59.9 degrees.
To find a line of best fit, you can select 2 points. Then, find the equation between them.
I choose the points (48.1, 26) and (28.4, 43). The slope between them is -0.86 and the y-intercept would be 67.3. Put those two parts together and you have the equation.
You can also use an online calculator to find the best possible line.
Answer:
1/3
Step-by-step explanation:
the y-intercept is when x=0, so, if x was 0, y is1/3

(4x-3+30)/(65) = (4x-3)/(65-26)
4x+27/65 = 4x-3/39
39(4x+27) = 65(4x-3)
156x+1053= 260x -195
-104x = -1248
x= 12
