Answers

Answer 1

Answer:

x = 4

Step-by-step explanation:

Given:

(√x + 2)(√x - 2) = 0

Required:

Find x

SOLUTION:

√x(√x - 2) + 2(√x - 2) = 0 (distributive property)

x - 2√x + 2√x - 4 = 0

x - 4 = 0

x - 4 + 4 = 0 + 4

x = 4

Classify the equation as a conditional equation, an identity, or a contradiction. 4x+5x−15=9x−10−5

Answers

Answer:

Identity

Step-by-step explanation:

Conditional equation, an identity, or a contradiction.

Conditional equation: Two sides are equal for some value of x.

Identity: Two sides are equal for every value of x.

Contradiction: We have 0x = number that is not 0.

4x+5x−15=9x−10−5

Lets solve

[tex]4x + 5x - 15 = 9x - 10 - 5[/tex]

[tex]9x - 15 = 9x - 15[/tex]

Equal on both sides, so identity.

Answer:

conditional equation

Step-by-step explanation:

Collecting terms on both sides, we get

−4+3x−5x−2x−4=−1−10+x=x−11

Subtracting x and adding 4 to both sides of the equation, we get

−3x=−7

This can be solved by dividing by −3 on both sides of the equation, which gives a unique solution of 73. So, this is a conditional equation.

What is the equation?

Answers

Answer:

y=-2+4

Step-by-step explanation:

we know the y intercept is four, so we can plug that into y=mx+b

so far we know y=mx+4

and the equation for finding slope is [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

so let's find two points on the graph

let's make it easy on ourselves and use the points laid out for us

(0,4) and (2,0)

[tex]\frac{0-4}{2-0}[/tex]

solving that would come out to be [tex]\frac{-4}{2}[/tex]

simplified, that would be -2

now that we know the slope, we can put them into slope-intercept form

y=-2+4

how do you write the point-slope form of the equation that has a slope of -5/6 point (8,-4)

Answers

Answer:

Step-by-step explanation:

the equation of a line in

point-slope form

is.

xy − y1 = m(x−x1)

where m is the slope and (x1 - y1 ) a point on the line

to calculate m use the

gradient formula

m= y2−y1

     x2−x1

let ( x1 , y1) =( 8, 5) and ( x2 ,y2 ) = (0, −4)

⇒ m= -4-5/0-8= -9/-8= 9/8

using m= 9/8 and (x1- y1) = (8,5) then

y-5= 9/8(x-8)

What is the distance between (4, 6) and (5, 0)

Answers

Answer:

6 units

Step-by-step explanation:

Given data

x1=4

y1=6

x2=5

y2=0

substitute in the formula for the distance between two points

d=√((x_2-x_1)²+(y_2-y_1)²)

d=√((5-4)²+(0-6)²)

d=√((1)²+(6)²)

d=√36)

d=6

Hence the distance is 6 units

The trigonometric function gives the ratio of different sides of a right-angle triangle. The Sine or Sinθ in a right angle triangle is the ratio of its perpendicular to its Hypotenuse.

What is Sine (Sinθ)?

The Sine or Sinθ in a right angle triangle is the ratio of its perpendicular to its Hypotenuse. it is given as,

Sin(θ) = Perpendicular/Hypotenuse

where,

θ is the angle,

Perpendicular is the side of the triangle opposite to the angle θ,

The hypotenuse is the longest side of the triangle.

The angle of elevation is equal to,

The angle of elevation = Sin⁻¹ (4.5/11.75)

                                      = 22.5183° ≈ 23°

Hence, the angle of elevation formed by the ramp by the ground to the nearest degree is 23°.

Solve the system using the substitution method

x = -6y - 4
6x - 12y = 24

Answers

Answer:

x = 2, y = -1

Step-by-step explanation:

We have a solution system, x = -6y - 4 and 6x - 12y = 24.

Now, since are not only asked to use the substitution method, but at the same time know the value of x, let's plug the first system into the second.

x = -6y - 4

6(-6y - 4) - 12y = 24

-36y - 24 - 12y = 24

-48y - 24 = 24

Add 24 to both sides :

-48y = 48

Divide -48 by both sides :

y = -1

Now that we have y, we can replace it into the second system again to get x.

6x - 12(-1) = 24

6x + 12 = 24

Solve for x by first getting rid of 12 from both sides :

6x = 12

Divide 6 by both sides :

x = 2

Therefore, x = 2 and y = -1

Rotate the figure 90 degrees about vertex A.

Answers

Answer:

A' is (1,1) B is (4,1) C is (1,-1)

Step-by-step explanation:

Since we rotating the figure about point a, we know a is the center of the rotation meaning no matter how far we rotate point a new image will stay on where point a pre image was which in this case is (1,1). Also since we know the rules of rotating a angle 90 degrees About the origin we are going to translate the figure to have the one point we are rotating about at the orgin. Since translations are a rigid transformations, the figure will stay the same A. Move the figure 1 to the left and 1 down so A becomes 0,0 B becomes 0,3 and C becomes 2,0. Then apply the rules of 90 degree clockwise rotation rules. (x,y) goes to (y,-x) . A stays (0,0) B becomes (3,0) and C becomes (0,-2). Then translate the figure 1 to the right and 1 down since we rotating about point a which is 1,1 and it at 0,0 rn. A' is 1,1. B' becomes (4,1). C' becomes (1,-1).
