Solve the following equation algebraically:
-16 = 16x?
How many solutions does this equation have? Explain.
a. -1 = x3; One solution because only -1 will satisfy the equation.
b. -1 = x2; No real solution because there is no real number that, when squared, produces -1.
c. 1= x?: Two solutions because the square root of 1 is positive 1 and negative 1.
d. 1=-x?: One solution because only -1 will satisfy the equation.

Answer and Step-by-step explanation:

RO = OW = 5.1

BRW + ORW = BRO = OWB

57 + 42 = 99 = OWB

I'm not entirely sure if these are correct, if its not, then im sorry.

Omitted / Incomplete Question : Judy has read 4 Less than three times as many as Jason

Answer:Jason has read  7 mystery novels and Judy has read  17 mystery novels

Step-by-step explanation:

Total number of mystery books read by  Jason and Judy =24

Let Number of mystery books read by Jason=x

and  Number of mystery books read by Judy= 3x-4

So that the total number of book read by both of them will be expressed as

x +(3x-4) =24

x +3x-4 =24

4x=24+4

4x=28

x=28/4=7

There fore  Jason has read  7 mystery novels

and Judy = 3x-4 = 3 X 7- 4 =21-4=17mystery novels

Answer:

The bearing of B from C is 22° counterclockwise

Step-by-step explanation:

∠CAB = 210 - 90 = 120°

Extend a line from A to the west.

drop a perpendicular line from that line to point C.

Let's call the point at the perpendicular point, M.

∠MAC = 180° - 120° = 60° because they are supplementary.

Now we have a right ∠CMA with a known hypotenuse and a known angle.

Solve for MA:

cos 60° = MA/3.8 = 1.9

Solve for MC:

sin 60° = MC/3.8 = 3.29

MB = 1.9 + 6.4 = 8.3

tan ABC = 3.29/8.3 = 21.62°

Answer:

1) 36 + 50 = 86 : Addition property of equality

2) m<D = m<ADB : If two angles have the same measure, then they are equal.

3) <D congruent to <ADB : if two angle are equal, then they are congruent.

4) <D, <ADB are alternate interior angles: assumed from diagram

5) CD // AB : if alternate interior angles are congruent, then the 2 lines cut by a transversal are //.

6) 130 + 50 = 180 : addition property of equality

7) m<E, m<BAE are supplements : if the sum of two angles equal to 180, then they are supplements.

8) <E, <BAE are same-side interior angles : assumed from diagram

9) EF // AB : if same-side interior angles are supplements, then the 2 lines cut by a transversal are //.

Given:

Alexis has a rectangular backyard that is 50 yards by 55 yards.

She wants to build a fence that stretches diagonally from one corner to the opposite corner.

To find:

The length of the fencing she needs.

Solution:

We have,

Length = 50 yards

Width = 55 yards

We know that, the diagonal of a rectangle is

[tex]Diagonal=\sqrt{length^2+width^2}[/tex]

[tex]Diagonal=\sqrt{(50)^2+(55)^2}[/tex]

[tex]Diagonal=\sqrt{2500+3025}[/tex]

[tex]Diagonal=\sqrt{5525 }[/tex]

On further simplification, we get

[tex]Diagonal=74.3303437[/tex]

[tex]Diagonal\approx 74.3[/tex]

Therefore, the length of the required fencing is 74.3 yards.

cosФ = opp/hyp     sinФ = adj/hyp        hyp = 10      perimeter = a + b + c

for the 45° right triangle

a = b     so      2a² = hyp²                       perimeter 45 = a + a + hyp    

P45 = 2a + hyp         a = sin(45) (hyp)  = [1/2√2)] (hyp)        sin(45) = (√2)/2

P45 = 2([1/2√2)] (hyp) + hyp

P45  = hyp (√2 + 1)

for the 30° right triangle

a = hyp×sin(30)     b = hyp×cos(30)           perimeter 30 = a + b + hyp    

            sin(30) = 1/2       cos(30) = (√3)/2

a  = hyp(1/2)           b = hyp(1/2)(√3)

P30 =        a        +      b         + hyp

        =  hyp(1/2)  +  hyp(1/2)(√3) + hyp

        =  hyp[ 1/2  +  (1/2)√3  + 1]

        =  hyp[ 1/2  +  (1/2)√3  + 1]             factored out the hyp

        =  (1/2)hyp[ 1 + √3 + 2]                  factored out a 1/2

P30  =  (1/2)hyp[ 3 + √3]

which is greater  P45 or P30?   vso I set both perimeters equal to each other

              P45           vs             P30

      hyp (√2 + 1)     =    (1/2)hyp[ 3 + √3]            the hyp cancel

               (√2 + 1)     =    (1/2)[ 3 + √3]                    still tough to tell  needed

               1.414 + 1    =    (1/2)[ 3 + 1.732]                to go to the calsulator

                 2.414      vs    1/2( 4.732)

                 2.414      >     2.366        thus P45 > P30    < -----  Final Answer

Answer:

Step-by-step explanation:

For two lines to be perpendicular to each other the product of their slopes must be -1.

First we need the slope of the reference line. Since

y=mx+b, where m is the slope and the line we are given is

y=2x-4

So we know the slope is 2. So our perpendicular will satisfy

m1(m2)=-1

2m=-1

m= -1/2

So now our line is

y=-x/2+b, using point (0,-7)

-7=-0/2+b

-7=b, now we have the complete line

y=-x/2-7

(Or more neatly)

y=(-x-14)/2

Answer:

Below.

Step-by-step explanation:

First find the perpendicular  height of the pyramid.

The median of one of the faces, the height and  and half the length of the square base make a right triangle with base 2 and hypotenuse 5, so using the Pythagoras theorem:

5^2 = 2^2 + h^2

h^2 = 5^2 - 2^2 = 21

h = √21 inches.

The volume of the pyramid V = 1/3 * h * area of the base, so

V = 1/3 * 4^2 * √21

= 24.44 in^3 to nearest hundredth.

The volume of a right square pyramid will be (16√21) / 3 cubic units.

Let h be the height of the pyramid, l be the slant height and A be the base area of the pyramid.

Then the volume of the pyramid will be

Volume = (1/3) × A × h

The slant height is given as.

l² = (half of side)² + h²

A right square pyramid has a slant height of 5 inches and the length of the base is 4 inches.

Then the height of the pyramid will be

5² = (4/2)² + h²

h² = 25 - 4

h = √21 inches

Then the volume of a right square pyramid will be

Volume = (1/3) × 4 × 4 × √21

Volume = (16√21) / 3

Thus, the volume of a right square pyramid will be (16√21) / 3 cubic units.

Step-by-step explanation:

45--120

75--215

145--400

The required expression for climbing the rock formations is given as y = 95x + 25.

Given,

[x]Climb Height (feet) Time (minutes)(y)

1                120

2               215

3               400

Functions is the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

here,
The standard linear equation is given as,
y -y₁ =(y₂ - y₁) /  (x₂ - x₁) (x - x₁)

put the values from the data table,

y - 120 = [(215-120)/(2-1)](x - 1)
y = 95(x - 1) + 120
y = 95x - 95 + 120
y = 95x + 25

Thus, the required expression for climbing the rock formations is given as y = 95x + 25.
