In Exercises 1-6, write the equation in standard form. Then identify the values of
a, b, and that you would use to solve the equation using the Quadratic Formula.
1. r = -5x
2 x + 3x -10
3.-5x + 2 = 7x
4. + 2x = 9
5. 6x - 1 - 7x?
6.-10x + 2 = -4x2 + 9
In Exercises 7-12, determine the number of real solutions of the equation (find and
use the discriminant).
7. x + 2x + 1 = 0 8. x - 4x - 7 = 0 9. 3x - 2x = -6
10.4x -3x - 8
11.-2x - 4x + 7 = 0
12.1? + 6x + 9 = 0

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950

step-by-step explanation:   divide the numerator by the denominator to get the decimal

it would still be 193

if divide by 100 then 1.93
