Answer:

Option A

- x² + 2x - 6

Step-by-step explanation:

Here,

f(x) = 2x + 1

g(x) = x² - 7

Now,

(f - g)(x)

= f(x) - g(x)

= 2x + 1 - x² - 7

= 2x - x² - 7 + 1

= 2x - x² - 6

= - x² + 2x - 6

Thus, (f - g)(x) = - x² + 2x - 6

Step-by-step explanation:

f(x)=2x+1

g(x)=2x-7

now,

f-g(x)=f(x)-g(x)
2x+1-2x+7
8

(f-g)(x)=8

hope it helps.

Find the A) slope B) Point Slope equation and C) Slope Intercept form of the line through points (9,18),(-4,14)

Lana71 [14]

Answer:

Step-by-step explanation:

A) Use the slope formula to find the slope m.

m=4/13

B) Use the point-slope formula, y−y1=m(x−x1) to find the equation of the line.

y=4/13x+198/13

C) Write in slope-intercept form, y=mx+b.

y=4/13x+198/13

Please help. I don't understand this.

klio [65]

Answer:

radius=6

Step-by-step explanation:

arc ACB=6xPi

Pi=3.14159

arc ACB=18.85 (rounded to 2 places)

ACB is a half circle so a full circle would be 18.85x2 or 37.7

circumference (whole circle)=2 x Pi x radius

37.7=2 x 3.14159 x radius

radius= 37.7/(2 x 3.14159)

radius=6

algol [13]

Answer: Inequality

Step-by-step explanation:

From the question, if we can describe 15×-10 as an expression, then we would describe 6×-2< 35 as an inequality. An

inequality is used to compare two values, and shows if one is less than, or greater than, or maybe not equal to the other value.

For example, a ≠ b means that a is not equal to b and a < b means a is less than b while a > b means a is greater than b. From the question, 6×-2< 35 means that 6x - 2 is less than 35.
