By looking at the graph, we can visually determine that the value of y when point x = -2 is <u>-4.</u>
Answer:
Nina is not correct because 393.5$ less then yesterday's ticket sales.
Step-by-step explanation:
To find total sales she he is not correct because
3 / 4 of 1440 = 1,080$ ticket sales from yesterday
and 295.25 - 33.50 = 261.75$
Therefore, ( 3 / 4 * 1440 ) + ( 295.25 - 33.50 ) = 1,341.75$ sale of today
Ticket from yesterday and today
1,080 - 1,341.75 = 393.5
393.5$ less then yesterday's ticket.
Answer:
l = 24ft
Step-by-step explanation:
A = lw
360 = (x + 9)(x)
360 = x^2 + 9x
0 = x^2 + 9x - 360
0 = (x + 24)(x - 15)
x ≠ -24 (length cannot be negative)
x = 15
l = 15 + 9
l = 24ft
Linear regression line y=2.1x+130 predicts sales based on the money spent on advertising.
Linear regression represents the relationship between two variables. the value of y depends on the value of x.
x represents the dollars spent in advertising and y represents the company sales in dollars.
We need to find out sales y when $150 spends on advertising.
Plug in 150 for x and find out y
y = 2.1 x + 130
y = 2.1 (150) + 130
y= 445
The company expects $445 in sales
