Multiple 15 by 6, the answer is 90 square cm
9514 1404 393
Answer:
58
Step-by-step explanation:
The marked points on the graph show that the number of hot cocoas sold decreases by 6 when the temperature goes up by 6 degrees. That is, the line has a slope of -1. The y-intercept is 100, so the equation of the line can be written as ...
y = mx +b . . . . . line with slope m and y-intercept b
y = -x +100
Then for x = 42, the expected value of y is ...
y = -42 +100 = 58
Mei Mei can expect to sell 58 hot cocoas on a day when the high is 42°F.
17. 2x<16 x=7 or lower
All I can help you with is #17,
sorry that I can't answer the other 3.
I hope this helped! :-)
-3(-4y+3)+7y
First multiply -3 by the terms in the parentheses
-3(-4y+3) = 12y -9
Your expression now looks like
12y -9 +7y
Then combine the terms containing the variable y
12y + 7y = 19 y
Your final answer is
19y - 9 (answer choice A)
Answer: x > 20
Step-by-step explanation:
first, i removed the parentheses.
2x - 6 + 5 > 39
then i calculated it.
2x - 1 > 39
then, i moved the constant to the right.
2x > 39 + 1
then, i added the two.
2x > 40
finally, i divided both sides.
solution: x > 20
