Answer: x=-1+2

Step-by-step explanation:

Answer:

Step-by-step explanation:

Subtract 2x from both sides of the equation.

X2-1=−2x

Add 1 to both sides of the equation.

X2=−2x+1

Take the square root of both sides of the equation to eliminate the exponent on the left side.

X=±√−2x-1

The complete solution is the result of both the positive and negative portions of the solution.

First, use the positive value of the ± to find the first solution.

X=√−2x+1

Next, use the negative value of the ± to find the second solution.

X=−√−2x+1

The complete solution is the result of both the positive and negative portions of the solution.

X=√−2x+1

X=−√−2x+1

Answer:

y = -3x

Step-by-step explanation:

To get slope intercept, you divide both y values by both x values like this

[tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]

In this case this will be [tex]\frac{(-3 - 6)}{(1 - (-2))}[/tex]

This will become [tex]\frac{-9}{3}[/tex]

Divide those two to get -3, and now you get your slope intercept.

Answer:

∠6 = 61°

Step-by-step explanation:

In order to solve this, you need to know what "vertical angels" are. Based on the fact that the angle that is 61° and angle 6 make a pair of vertical angles, we know that both of these angles are equal to each, therefore ∠6 = 61°.

Answer:

Here we have the function:

S(t) = 500 - 400*t^(-1)

Then the rate of change at the value t, will be:

S'(t) = dS(t)/dt

This differentiation will be:

S'(t) = -400/t^2

Then:

a) the rate of change at t = 1 is:

S'(1) =  -400/1^2 = -400

The rate of change after one year is -400

b) t = 10

S'(10) = -400/10^2 = -400/100 = -4

The rate of change after 10 years is -4, it reduced as the years passed, as expected.

Answer:

△ VUW = △ KJI

Step-by-step explanation:

In △ VUW, △ KJI,

UW = JI ( Sides are equal )

∠ VUW = ∠ KJI ( From the diagram )

∠ UWV = ∠ KIJ ( From the diagram )

By ASA rule of congruency,

△ VUW is congruent to △ KJI.

Answer: System 1 has an infinite number of solutions and System II has no solutions.

Step-by-step explanation:

If we look at system 1, we see that if we multiply the first equation by 2 and subtract the y value so that its on the same side as x, the equations are the same. That means that no matter the x or y value, it will be a solution.

If we look at system 2, however, we see that if we multiply the top equation by 3, the equations are the exact same except for the fact that the top equation has a -21. This means that no matter the x or y, there will never be a solution.

17) [tex]- \frac{3}{2}[/tex]

18) [tex]\frac{5}{4}[/tex]

19) [tex]-\frac{1}{2}[/tex]

20) [tex]\frac{2}{5}[/tex]

Step-by-step explanation:

Slope intercept form: y = mx + b

y = (x , y)

x = (x , y)

slope = m

b = y-intercept

17) -4y + 16 = 6x

Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

First, subtract 16 from both sides of the equation:

-4y + 16 (-16) = 6x (-16)

-4y = 6x- 16

Next, divide -4 from both sides of the equation:

(-4y)/-4 = (6x - 16)/-4

y = (6x)/-4 + (-16)/-4

y = -3x/2 + 4

Slope: [tex]-\frac{3}{2}[/tex]

~

18) 0 = -12y -36 + 15x

Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

First, add 12y to both sides of the equation:

0 (+12y) =  - 12y (+12y) + 15x - 36

12y = 15x - 36

Next, divide 12 from both sides of the equation to isolate the variable, y:

(12y)/12 = (15x - 36)/12

y = (5/4)x - 3

Slope: [tex]\frac{5}{4}[/tex]

~

19) 3x = -6y

Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

Divide -6 from both sides of the equation:

(3x)/-6 = (-6y)/-6

y = 3x/-6

y = -(3/6)x

Simplify. Divide common factors from both the numerator and denominator.

-(3/6)/(3/3) = - 1/2

Slope: [tex]-\frac{1}{2}[/tex]

~

20) -2x -5 = -5y

Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

Divide -5 from both sides of the equation:

(-2x - 5)/-5 = (-5y)/-5

y = (-2x - 5)/-5

y = (2/5)x + 1

Slope: [tex]\frac{2}{5}[/tex]

Answer:

A:37

Step-by-step explanation:

A school got 5 copies, and the total for ALL the copies is $185.  So you need to take 185 and divide it by 5 because we need to find out how much each of the copies costs. If you do that then you will get the answer of $37 per copy

The price for each copy is $37 if the school bought 5 copies of a textbook this week the school spent a total of $185 on the 5 copies option (A) is correct.

Fraction number consists of two parts one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

We have:

Number of copies school bought = 5

Price for 5 copies  = $185

Let's assume the price for each copy = $x

So the value of x can be evaluated:

[tex]\rm x = \frac{185\times1}{5}[/tex]

x = $37

Thus, the price for each copy is $37 if the school bought 5 copies of a textbook this week the school spent a total of $185 on the 5 copies option (A) is correct.

#SPJ2

Answer:

Step-by-step explanation:    First, let's call the starting elevation of the plane: e

We can then write an equation representing this problem as:    

e−1.5mi=5.25mi

Now, add 1.5mi  to each side of the equation to solve for e

while keeping the equation balanced:

e−1.5mi + 1.5mi=5.25mi + 1.5mi

e−0=6.75mi

e=6.75mi

The plane's starting elevation was 6.75 miles

Answer:

57inches

Step-by-step explanation:

In order to determine how far the wheel travels, we will have to find the circumference of the wheel. This is expressed as;

Circumference of the wheel = 2πr

r is the radius of the wheel = 9in

Substitute

Circumference of the wheel = 2(3.14)(9)

Circumference of the wheel = 56.52inches

Hence the wheel travels 57inches to the nearest inch

f(4) = -18

g(-3) = -76

Step-by-step explanation:

f(x) = -5x + 2

f(4) = -5(4) + 2

= -20 + 2

= -18

g(x) = 3x^3 + 5

g(-3) = 3(-3)^3 + 5

= 3(-27) + 5

= -81 + 5

= -76

Answer:

F(4)= -18

G(-3)=-76

f(x)= -5x+2

g(x)=3x^3+5

To find f(4), wherever you see x in f(x) put in 4

-5(4)+2= -18

To find g(-3), wherever you see x in g(x) put -3

3(-3)^3 +5= -76
