Answer:

20

h(x) = 2x - 20

Step-by-step explanation:

f(x) = ¹/₂ x + 10

First, isolate x, like so:

f(x) - 10 = ¹/₂ x

x = 2(f(x) - 10)

x = 2f(x) - 20

Now, simply switch f(x) with x and x with h(x), like so:

h(x) = 2x - 20

Answer:

the answer is 20

2. put them together

3x + 9 is your answer.

Hope I helped! have a wonderful day!

Answer:

3x + 9

Step-by-step explanation:

Just add the both the x's together:

2x + x = 3x

Then add the regular numbers together:

4 + 5 = 9

then put the answers together:

3x + 9

Answer:

263(usually it would say cm or m)²

Step-by-step explanation:

area = l x w

l= 25

w= 19

25 x 19 = 551

thats the area without subtracting the missing area's.

missing area= 9 x 16

=144

since theres 2 areas missing, times it by two

144 x 2

=288

subtract the missing area from the total because its not there.

551 - 288

= 263

Answer:

49a^7

Step-by-step explanation:

Combine like terms (30+19 = 49)

Answer:

[tex]{ \bf{30 {a}^{7} + {19a}^{7} }} \\ = (30 + 19) {a}^{7} \\ = 49 {a}^{7} [/tex]

Answer:

49/8 is the value of k

Step-by-step explanation:

We have the system

x = -2y^2 - 3y + 5

x=k

We want to find k such that the system intersects once.

If we substitute the second into the first giving us k=-2y^2-3y+5 we should see we have a quadratic equation in terms of variable y.

This equation has one solution when it's discriminant is 0.

Let's first rewrite the equation in standard form.

Subtracting k on both sides gives

0=-2y^2-3y+5-k

The discriminant can be found by evaluating

b^2-4ac.

Upon comparing 0=-2y^2-3y+5-k to 0=ax^2+bx+c, we see that

a=-2, b=-3, and c=5-k.

So we want to solve the following equation for k:

(-3)^2-4(-2)(5-k)=0

9+8(5-k)=0

Distribute:

9+40-8k=0

49-8k=0

Add 8k on both sides:

49=8k

Divide both sides by 8"

49/8=k

Answer:

437.3ft

Step-by-step explanation:

last of sines

a/sin(A) = b/sin(B) = c/sin(C)

sin(90) = 1

the angle between y and 500ft side is 90-29 = 61 degrees.

so,

x/sin(61) = 500/1 = 500

x = 500 × sin(61) = 437.3ft

In a triangle, value of [tex]x = 437.4[/tex] units (round to nearest tenth) using trigonometric ratio.

"Trigonometric ratio is defined as in a right triangle the relation between the ratio of a sides of a triangle and the angle."

Formula used

[tex]sin\theta = \frac{opposite sides}{hypotenuse}[/tex]

[tex]cos\theta = \frac{adjacent sides}{hypotenuse}[/tex]

According to the question,

In a given right triangle ABC,

Hypotenuse [tex]=500 ft[/tex]

Opposite side [tex]= x ft[/tex]

Adjacent side [tex]= y ft[/tex]

As per the diagram drawn,

 [tex]\angle BAC+ 29\° = 90\° \\\\\implies \angle BAC = 90\° -29\° \\\\\implies \angle BAC = 61\°[/tex]

Substitute the value in the above trigonometric ratio formula we get,

[tex]sin61\° = \frac{x}{500}\\\\\implies 0.8747 = \frac{x}{500}\\\\\implies x = 500 \ times 0.8747\\\\\implies x = 437.35 ft[/tex]

[tex]\implies x = 435.4 ft[/tex] (round to nearest tenth)

In trigonometric ratio [tex]cos\theta[/tex] we get,

[tex]cos61\° = \frac{y}{500}\\\\\implies 0.4848 = \frac{y}{500}\\\\\implies y= 500 \ times 0.4848\\\\\implies y = 242.2 ft[/tex]

Hence , In a triangle, value of [tex]x = 437.4[/tex] units (round to nearest tenth) using trigonometric ratio.

Hi there!

[tex]\large\boxed{(0, -1)}[/tex]

-2x + 8y = -8

2x - 3y = 3

We must eliminate a variable to solve. We can add the two equations to eliminate x because -2 + 2 = 0:

-2x + 8y = -8

2x - 3y = 3

-----------------

0x + 5y = -5

5y = -5

y = -1

Substitute this value of y into an equation to solve for x:

-2x + 8(-1) = -8

-2x -8 = -8

x = 0

Thus, the solution of this system is:

(0, -1)

Answer:

(0,-1)

Step-by-step explanation:

Hi there!

We are given the system:

-2x+8y=-8

2x-3y=3

there are 3 ways to solve systems of equations: graphing, substitution, and elimination

let's solve this system by elimination, which we will add the 2 equations together to clear one variable, solve for the other variable, and plug the value of that variable to solve for the variable that was cleared earlier.  

add the two equations together (-2x and 2x clear out to equal 0 and we'll have only y left.)

 -2x+8y=-8

+

 2x - 3y= 3

_________

      5y=-5

divide by 5 on both sides

y=-1

now substitute y as -1 into one of the equations to solve for x

for example, we can do the second equation

2x-3(-1)=3

multiply

2x+3=3

subtract 3 from both sides

2x=0

divide by 2

x=0

therefore the answer is x=0, y=-1. If you need it as a point, it's (0,-1)

Answer: 4th week

Step-by-step explanation:

You just keep adding 150 to 250 for Sarah and subtract 200 from 1,650 for Felicia until they both have the same amount which would be 850.

At the end of 4th week Sarah and Felicia have same amount of money equals to $850.

"Amount is defined as representation of total of two or more quantities."

According to the question,

Amount with Sarah at the beginning of the week = $250

Amount save per week by Sarah = $150

Amount with Felicia at the beginning of the week = $1650

Amount save per week by Felicia = $200

As per the given conditions,

Sarah amount for different weeks:

At the end first week = $250 + $150

                                   = $400

At the end second week = $400 + $150

                                         = $550

At the end third week = $550 + $150

                                    = $700

At the end fourth week = $700 + $150

                                       = $850

Felicia amount for different weeks:

At the end first week = $1650 - $200

                                   = $1450

At the end second week = $1450- $200

                                         = $1250

At the end third week = $1250 - $200

                                    = $1050

At the end fourth week = $1050- $200

                                       = $850

Hence, at the end of 4th week Sarah and Felicia have same amount of money equals to $850.

Answer:

Yes

Step-by-step explanation:

We can make one equation other to the other to solve for x-value first;

=> -4x = x - 5

=> -4x + (-x) = -5

=> -5x = -5

=> x = -5/-5

=> x = 1

Once we have the x-value we can substitute it in for "x" in any equation to find the y-value;

=> y = x - 5

=> y = (1) - 5

=> y = -4

Writing the answer coordinate points would look like (x, y) which would be (1, -4) which is similar to the give, there for yes the solution to the equations is the given coordinate.

Answer:

8 / 17

Step-by-step explanation:

A triangle is a polygon with three sides and three angles. There are different types of triangles such as acute, isosceles, obtuse, scalene, equilateral and right angled triangle.

Trigonometric identities are used in a right angled triangle to show the relationship between the sides and the angles. They are:

sinθ = opposite / hypotenuse, cosθ = adjacent / hypotenuse, tanθ = opposite / adjacent

From the triangle attached:

sin(H) = opposite / hypotenuse

sin(H) = 8 / 17
