What are the coefficients in the polynomial 7x^2 -4x+6

1 answer:

8 0

7 and -4

Coefficients are the numbers before a variable, meaning that 7 and -4 (be careful of that subtraction sign) are the coefficients. Additionally if you were asked what the leading coefficient was the answer would be 7 because it has the greatest exponent attached to it (2).

Solve the inequality. -4x + 15 < -21

Dmitriy789 [7]

Answer:

x>9

Step-by-step explanation:

-4x + 15 < -21

Subtract 15 from each side

-4x + 15-15 < -21-15

-4x < -36

Divide each side by -4, remembering to flip the inequality

-4x/-4> -36/-4

x >9

Michael and Kathryn bowl together and their combined total score for one game was 425points. Michael’s score was 70 less than tw

In-s [12.5K]

Hey there!

Let us take Michael's score as ' x '

Let us take Kathryn's score as ' y '

Michael - 70 less than twice Kathryn's

x = 2y - 70

y = y

Add them, we get , 425

2y - 70 + y = 425

3y - 70 = 425

3y = 495

y = 495/3

y = 165

Kathryn's score = 165

Michael - 2 ( 165 ) - 70

= 260

Hope it helps!
