I have tried everything I could think of:

1. Translate into a variable expression.
six-sevenths of the sum of m and 5

2. Translate into a variable expression.
z increased by the difference between 12 times z and 9

3. Evaluate the variable expression when
a = 6, b = 7, and c = −5.
(b − 2a)2 + bc

4. Evaluate the variable expression when
a = −2, b = 5, c = −2, and d = 3.
b − 6a
bc2 − d

5. Evaluate the variable expression when
a = 2 and b = 4.
2a + 3b

6. Find the quotient of 288 and −9.

7. Find the product of −4, −7, −8, and −9.

Data are collected to see how many ice-cream cones are sold at a ballpark in a week. day 1 is sunday and day 7 is the following saturday. use the data from the table to create a scatter plot.

Use the quadratic formula to solve the equation. if necessary, round to the nearest hundredth. x^2 - 23 = 10x a. -1.93, 11.93 b. 1.93, -11.93 c. 1.93, 11.93 d. -1.93, -11.93
