Answer:

33 - 2x =  {x }^{2}  + 2x + 1 \\  {x}^{2}  + 4x - 32 = 0 \\ x = 8 \\   \\ x = 4

Answer:

x = 4

Step-by-step explanation:

(33-2x)^(1/2) = x + 1

33-2x = x^2 + 2x + 1           [square both sides]

x^2 + 2x + 1 - 33 +2x = 0

x^2 + 4x - 32 = 0

(x - 4)(x + 8) = 0

x = 4

I need to know the intercepts for y and x ASAP!!!!!!!<br> f(x) = -8x + 4 is the equation
Georgia [21]

Answer:

X-int: (1/2 , 0) . Y-int: (0 , 4)

Step-by-step explanation:

FOR X

To find the x-intercept, substitute in  0 for Y and solve for X.

0 = -8x + 4

1. Move 4 to the left side so it's -4 = -8x

2. Divide by -8 to isolate X so it's -4/-8 = x

3. The negatives cancel out and become positive

4. Answer: X = 1/2

FOR Y

To find the y-intercept, substitute in  0 for X and solve for Y.

Y = -8(0) + 4

1. Since anything multipled by 0 is 0, it simply becomes Y = 4.

Answer: Y = 4

from a point 48 feet from the base of a redwood tree, the angle of elevation to the top of the tree is 56.3°. Find the height of
Oksanka [162]

tangent(angle) = Opposite Leg ( Height) / Adjacent Leg ( base)


Tangent(56.3) = Opposite Leg / 48 feet


Opposite Leg = 48 x tangent(56.3) = 71.97


Height = 72 feet ( rounded to the nearest foot).

Sedbober [7]

Answer:

15 people voted yes and 3 people voted no.

Step-by-step explanation:

Given that:

Ratio of yes to no = 5 : 1

Total number of board members who voted = 18

Let,

x be the number of times.

5x+x = 18

6x = 18

Dividing both sides by 6

\frac{6x}{6}=\frac{18}{6}\\x=3

People who voted yes = 5(3) = 15

People who voted no = 3

Hence,

15 people voted yes and 3 people voted no.

Which statements include two quantities in the real world that are additive inverses?
galben [10]
It would be the answer with Juana. Additive integers are adding a postive and negative number to add to zero ex) -5+5=0. So in this situation you can think of west and east as positive and negative.
