Answer:

Step-by-step explanation:

y = -x^2 + x - 1

y = -x -1

-x-1 = -x^2 + x -1

x^2 -2x = 0

x( x-2) = 0

x1= 0 , x2 = 2

y(0) = 0-1 = -1

y(2) = -2-1 = -3

(0, -1) & (2, -3)

What is the equation of the line that passes through the point (-4,6)(−4,6) and has a slope of -\frac{5}{4}−

AysviL [449]

Answer:

5x + 4y - 4 = 0 is the given line equation.

Step-by-step explanation:

The slope m of the line is given as $-\frac{5}{4}$

The point of the equation is (x0, y0) = (-4, 6)

Now, by POINT SLOPE formula of a line:

Equation of a line is : ( y -y0) = m (x - x0)

Hence, the equation is $(y - 6) = -\frac{5}{4} (x -(-4))$

On further simplifying $4(y - 6) = -5 (x + 4)\\or, 4y - 24 = -5x- 20$ ,

⇒ 5x + 4y - 24 + 20 = 0

or, 5x + 4y - 4 = 0 is the given line equation.

Answer:

9 $\frac{8}{13}$

Step-by-step explanation:

change the mixed number to an improper fraction

1 $\frac{12}{13}$ = $\frac{25}{13}$ , then

5 × $\frac{25}{13}$

= $\frac{5(25)}{13}$ = $\frac{125}{13}$ = 9 $\frac{8}{13}$

Which statements are true of the given function?<br> Check all that apply.

skad [1K]

9514 1404 393

Answer:

B, E

Step-by-step explanation:

The table tells you that f(0) = 3/2. (0 is found in the x-column; 3/2 is found in the f(x) column.)

You can find f(4) by evaluating the formula.

f(4) = 1/2·4 +3/2 = 4/2 +3/2

f(4) = 7/2 . . . . agrees with last answer choice
