Natasha_Volkova [10]

Answer:

B. x = -4

E. x = 10

Step-by-step explanation:

(x-3)^2=49 \\  \\ x - 3 =  \pm \sqrt{49}  \\  \\ x - 3 =  \pm 7 \\  \\ x = 3 \pm 7 \\  \\ x = 3 + 7, \:  \: x = 3 - 7, \\  \\ x = 10, \:  \: x =  - 4

Voce 2x-u - 1x2-3x+3 = 2​
kumpel [21]

Answer:

u=−x2−x+1

Step-by-step explanation:

Let's solve for u.

2x−u−1x^2−3x+3=2

Step 1: Add x^2 to both sides.

−x2−u−x+3+x2=2+x2

−u−x+3=x2+2

Step 2: Add x to both sides.

−u−x+3+x=x2+2+x

−u+3=x2+x+2

Step 3: Add -3 to both sides.

−u+3+−3=x2+x+2+−3

−u=x2+x−1

Step 4: Divide both sides by -1.

−u/−1=x2+x−1

−1/u=−x2−x+1

Answer:

u=−x2−x+1

PLEASE HELP DUE NEXT PERIOD
Julli [10]

Answer:

y = - x + 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - x + 6 ← is in slope- intercept form

with m = - 1

Parallel lines have equal slopes, thus

y = - x + c ← is the partial equation

To find c substitute (2, - 1) into the partial equation

- 1 = - 2 + c ⇒ c = - 1 + 2 = 1

y = - x + 1 ← equation of line
