Step-by-step explanation:

so a minus divided by a plus is a minus so -8÷2 is -4.

Answer:

(2,-5) and (2,1).

Step-by-step explanation:

We need to find the find all the points having an x coordinate of 2 whose distance from the point (-2,-4) is 5.

A circle with center (-2,-4) and radius 5 represents all the points whose distance from the point (-2,-4) is 5.

Standard form of a circle is

[tex](x-h)^2+(y-k)^2=r^2[/tex]

where, (h,k) is center and r is the radius.

[tex](x-(-2))^2+(y-(-4))^2=(5)^2[/tex]

[tex](x+2)^2+(y+2)^2=25[/tex]

Now, put x=2.

[tex](2+2)^2+(y+2)^2=25[/tex]

[tex](4)^2+(y+2)^2=25[/tex]

[tex](y+2)^2=25-16[/tex]

[tex](y+2)^2=9[/tex]

Taking square root on both sides.

[tex]y+2=\pm\sqrt{9}[/tex]

[tex]y+2=\pm3[/tex]

[tex]y+2=-3\text{ or }y+2=3[/tex]

[tex]y=-5\text{ or }y=1[/tex]

So, the y-coordinates of the points are -5 and 1.

Therefore, the required points are (2,-5) and (2,1).

Answer:

y = - 6

Step-by-step explanation:

Given

8 - (y + 3) = 11 ← distribute and simplify left side

8 - y - 3 = 11

5 - y = 11 ( subtract 5 from both sides )

- y = 6 ( multiply both sides by - 1 )

y = - 6

Step-by-step explanation:

Use power rule and chain rule.

y = cos²(5x³ − 2x)

dy/dx = 2 cos(5x³ − 2x) (-sin(5x³ − 2x)) (15x² − 2)

dy/dx = 2 cos(5x³ − 2x) sin(5x³ − 2x) (2 − 15x²)

Use double angle formula to simplify:

dy/dx = sin(10x³ − 4x) (2 − 15x²)

Greetings from Brasil...

According to the annex, we note that

1 qt = 1 quart = 0.95L

To solve this problem, just apply some rules of 3.....

1st - how many qt's are in 15.5 cups

  qt                 cup

   1   ----------     4

   X  ----------   15.5

4 · X = 1 · 15.5

4X = 15.5

X = 15.5 ÷ 4

X = 3.875qt

Last rule of 3 to know how many liters there are in 3.875qt:

  qt                       litres

   1         ----------    0.95

3.875    ----------      Y

1 · Y = 0.95 · 3.875

Answer:

$18,432

Step-by-step explanation:

After the first year, the speedboat is now worth $36,000 because 20% of 45,000 is 9,000, and 45,000 - 9,000 = 36,000. After the second year, it is now worth $28,800. After the third year, it is worth $23,040 since 20% of 28,800 is 5,760 and 28,800 - 5,760 = 23,040. After four years, the boat that once was worth $45,000 is now worth $18,432.

After 4 years, the value of boat is $9,000.

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

We have to given that;

A speedboat costs $45,000 is depreciating at a rate of 20% per year.

So, The depreciating amount after one year = 20% of $45,000

                                                                    = 20/100 × 45,000

                                                                    = $9,000

Thus, The value of boat after 4 years = $45,000 - 4 × $9,000

                                                         = $45,000 - $36,000

                                                         = $9,000

Area of ΔABF = 6 square units

Step-by-step explanation:

A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The area of the ΔABF is 6 units².

A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The sum of all the angles of a triangle is always equal to 180°.

To find the area of the ΔABF, we need to find the length of the base and the altitude of the triangle. Therefore, we can write the lengths as,

Base, FA = [tex]\sqrt{[-5-(-2)^2]+[4-1]^2}[/tex]

               =√[(-5+2)² + (3)²]

               = √[(-3)² + (3)²]

               = √(9 + 9)

               = √18

               = 3√2

Altitude, BF = [tex]\sqrt{[0-(-2)^2]+[3-1]^2}[/tex]

                   =√[(0+2)² + (2)²]

                   = √[(2)² + (2)²]

                   = √(4 + 4)

                   = √8

                   = 2√2

Now, the area of the triangle can be written as,

Area of the triangle = (1/2) × Base × Altitude

                                = 0.5 × 3√2 × 2√2

                                = 6 units

Hence, the area of the ΔABF is 6 units².

Answer: B. Yes, but doing so will clear out his account.

Step-by-step explanation:

I just took a test and answered it correct.

Since Adam’s bank account has a balance of $1213.69 before he starts spending money. So, option b.Yes, but doing so will clear out his account.

Since

Adam’s bank account has a balance of $1213.69 before he starts spending money.

The total of transactions should be like

= $260.16 + $97.98 + $75 + $115.35 + $68.53 + $331.84

= $948.85

Now the balance amount is

= $1,213.69 - $948.85

= $264.84

[tex]h^{-1}[/tex](x) = [tex]\frac{2}{3}[/tex] x + 11

Step-by-step explanation:

let y = h(x) and rearrange making x the subject , that is

y = [tex]\frac{3}{2}[/tex] (x - 11 ) ← multiply both sides by 2 to clear the fraction

2y = 3(x - 11) ← distribute

2y = 3x - 33 ( add 33 to both sides )

2y + 33 = 3x ( divide all terms by 3 )

[tex]\frac{2}{3}[/tex] y + 11 = x

Change y back into terms of x with x = [tex]h^{-1}[/tex](x) , thus

[tex]h^{-1}[/tex](x) = [tex]\frac{2}{3}[/tex] x + 11

Answer:

y=7.51

Step-by-step explanation:

First, you have to simplify one of the equations down

3x-y=4

y=-4+3x

Second, you insert the value of y into the other equation and then solve for x

9x+5(-4+3x)=8

9x-20+15x=8

24x=28

x=1.17

Last, insert the value of x into the original equation and then solve for y

y=4+3(1.17)

y=7.51
