-1.5 + 7.5

factor out -1.5, divide 7.5 by 1.5 to factor it out of it as well (7.5 divided by -1.5) and make sure you get NEGATIVE 5.

-1.5(1 x -5)

Choose the equation of the line that has a slope of zero and passes through the point (6, -3).
olga2289 [7]

Answer:

y= -3

Step-by-step explanation:

Since there is no slope, there is no mx in y=mx+b. Because the line has to go through point (6,-3), the y-intercept is -3.

I need help for a and b!!!
Taya2010 [7]

A)

acd = a + b

(Get the value of B from image)

136 = a + 56

(Subtract 56 from both sides)

136 - 56 = a

(Solve 136 - 56)

a = 80


(C is supplementary with 136)

136 + c = 180

(Subtract 136 from both sides)

c = 180 - 136

(Solve 180 - 136)

c = 44


Therefore:

a = 80 and c = 44


B)

egh = e + f

(Get values from image)

63 = e + 23

(Subtract 23 from both sides)

63 - 23 = e

(Solve 63 - 23)

e = 40


(G is supplementary with 63, supplementary angles equal 180

63 + g = 180

(Subtract 63 from both sides)

g = 180 - 63

(Solve 180 - 63)

g = 117


Therefore

e = 40 and g = 117

For f(x) = 2x + 1 and g(x) = x^2 - 7, find (f-g)(x)
Andre45 [30]

Answer:

\displaystyle (f - g)(x) = -x^2 + 2x + 8

Step-by-step explanation:

We are given the two functions:

\displaystyle f(x) = 2x + 1 \text{ and } g(x) = x^2 - 7

And we want to find:

\displaystyle (f- g)(x)

Recall that:

\displaystyle (f - g)(x) = f(x) - g(x)

Substitute and simplify:

\displaystyle \begin{aligned}(f-g)(x) &= f(x) - g(x) \\ \\ &=  (2x + 1)  - (x^2 - 7) \\ \\ &= (2x +1 )+ (-x^2 + 7) \\ \\ &= -x^2 +2x + 8\end{aligned}

In conclusion:

\displaystyle (f - g)(x) = -x^2 + 2x + 8

Sever21 [200]

Answer:

True?

Step-by-step explanation:

Because even if you multiply 1/6 by -200 the number is still going to be negative, which means less than 1/6?
