PLZ help me ASAP its due in a couple of mins!!! :((((( which one is it??

Answer:

D.

Step-by-step explanation:

A function has to have only one y-value for every x-value. This means that D is not a function because it contains (6,2) and (6, 4), which means that there are 2 different y-values for the x-value of 6.

Answer:

y = -6/5x - 5.6

Step-by-step explanation:

6x + 5y = 6

-6x          -6x

5y = -6x + 6

/5y    /5y

y = -6/5y + b

-2 = -6/5(-3) + b

-5.6 = b

The equation of line passing through the point (-3,-2) and parallel to line 6x+5y=6 is  6x+5y = -28.

What is equation of line?

Equation of line is a linear equation with a degree of one. The equation of line can be formed with the help of the slope of line and a point on the line.

[tex](y-y_{1}) = m(x-x_{1} )[/tex]                          

(where [tex](x_{1} ,y_{1} )[/tex] is a point through which a  line is passing)

According to the question

We have

A equation of line 6x+5y=6

and, a point (-3,-2)

so, the slope of the line 6x+5y=6

⇒[tex]5y=6x-6[/tex]

⇒ [tex]y=\frac{-6}{5} x +\frac{6}{5}[/tex]  

the  slope of the line 6x+5y=6 is [tex]\frac{-6}{5}[/tex]

Therefore, the equation of line which is parallel to the line 6x+5y=6 and passing through the point (-3, -2) is given by

[tex](y-y_{1} )=m(x-x_{1} )[/tex]

⇒[tex](y-(-2))=\frac{-6}{5} (x-(-3))[/tex]            (slope of the parallel lines are equals)

⇒[tex](y+2)=\frac{-6}{5}(x+3)[/tex]

⇒ [tex]5y+10=-6x-18[/tex]

⇒[tex]5y+6x=-28[/tex]

⇒[tex]5y+6x+28=0[/tex] or [tex]6x+5y=-28[/tex]

Hence, equation of line which is passing through (-3,-2) and parallel to line 6x+5y=6 is 6x+5y=-28.

Answer:

13 = x

Step-by-step explanation:

Remark

The six exterior angles add up to 360. In fact the exterior angles of any closed convex figure adds up to 360.

You can try this with simple figures. An equalateral triangle has 3 equal exteror angles. They are all 120 degrees 3*120 = 360

A square has 4 exterior angles. All 4 of them are 90 degrees. The sum of them is 90 * 4 = 360

Givens

Angles

The Total is 360 degrees

Solution

3x + 6 + 7x - 11 + 62 + 4x + 7 + 6x - 5 + 41 = 360    Combine like terms

20x + 100 = 360                  Subtract 100 from both sides

20x = 360 - 100

20x = 260

x = 13

Answer:

Ruffly 6.5

Step-by-step explanation:

a^2+b^2=C^2

In this case we need to find a so we do c^2-b^2.

9.8^2-7.3^2=42.75

Square root of 42.75 is ruffly 6.5

Answer:

6.5 km

Step-by-step explanation:

hypotenuse (h)=9.8km

base(b)=7.3km

perpendicular (p)=?

we know,

p^2 =h^2-b^2

p^2=(9.8)^2-(7.8)^2

p^2= 96.04-53.29

p^2=42.75

(p)^2=(6.5)^2

p=6.5km

Answer:

Step-by-step explanation:

The equation of a line which passes through (x₁, y₁) and with slope of m in point-slope form:

                            y - y₁ = m(x - x₁)

m = -5

(-2, 7)    ⇒   x₁ = -2,  y₁ = 7

y - 7 = -5(x - (-2))

y - 7 = -5(x + 2)            

(a, 2)   ⇒   2 - 7 = -5(a + 2)

                   -5 = -5a - 10

                   5a = 5 - 10

                     5a = -5

                       a = -1

try 28.4 inches to the 3rd power

Step-by-step explanation:

Step-by-step explanation:

Given

[tex]q + p = 2(q - p)[/tex]

as equation 1.

I used q-p as the difference as logically the woman will be older than her son.

Also given,

[tex]qp = 675[/tex]

as equation 2.

Using equation 2,

[tex]q = \frac{675}{p} [/tex]

substitute this equation into equation 1.

[tex] \frac{675}{p} + p = 2( \frac{675}{p} - p) \\ \frac{675}{p} + p = \frac{1350}{p} - 2p \\ \frac{675}{p} - \frac{1350}{p} = - 2p - p \\ - 3p = - \frac{675}{p} \\ - 3p \times p = - 675 \\ - 3 {p}^{2} = - 675 \\ {p}^{2} = - 675 \div - 3 \\ {p}^{2} = 225 \\ p = \sqrt{225} \\ = 15[/tex]

Substitute P into equation 2.

[tex]15q = 675 \\ q = 675 \div 15 \\ = 45[/tex]

Therefore the woman is 45 years old while her son is 15 years old.

Answer: x=22.0 (nearest tenth)

Step-by-step explanation:

For this question you have to find out whether you are using Sin, Cos, Tan.

To which one you are using you can use SOH CAH TOA to help you.

SOH- The 'S' is for Sin and then the 'O' and the 'H' is for Opposite over Hypotenuse.

CAH- The 'C' is for Cos, then the 'A' and the 'H' is for Adjacent over Hypotenuse.

TOA- The 'T' is for Tan, the 'O' and the 'A' is for Opposite over Adjacent.

Because we have the Adjacent (angle next to 60°) and the Hypotenuse we would be using Cos.

So first you would write:

Cos 60=11/x

Then we would have to do the inverse to 'undo' the equation to get x on it's own. This would then look like:

x Cos 60=11

Then we do the inverse again:

x=11/Cos 60

so, x=22.0 (to the nearest tenth)

Hope this helps :)
