Answer:

perpendicular

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

3x = y - 5 ( add 5 to both sides )

3x + 5 = y ← in slope- intercept form

with slope m = 3

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

9y + 4x = x - 9 ( subtract 4x from both sides )

9y = - 3x - 9 ( divide all terms by 9 )

y = - [tex]\frac{1}{3}[/tex] x - 1 ← in slope- intercept form

with slope m = - [tex]\frac{1}{3}[/tex]

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

Parallel lines have equal slopes

The product of the slopes of perpendicular lines = - 1

Thus

the slopes are not equal, thus not parallel lines.

3 × - [tex]\frac{1}{3}[/tex] = - 1 , hence lines are perpendicular

Answer:

x>-15

Step-by-step explanation:

Answer:

4 bowls

Step-by-step explanation:

Conversion rate :

1 liquid pint = 16 fluid ounces

From the question, we are told that :

4 fluid ounces of bubble mix = 1 bowl

16 fluid ounces of bubble mix(1 liquid pint) = y bowl

Cross Multiply

4 fluid ounces × y bowl = 16 fluid ounces × 1bowl

y bowl = 16 fluid ounces × 1bowl/4 fluid ounces

= 4 bowls

Therefore, he can fill 4 bowls with 1 pint of bubble mix

Answer:

NUMBER 2) x>_3/7

Step-by-step explanation:

-2(2-2x)-4(x+5) is less than or equal to -24

-2(2-2x)-4(x+5) <_ -24        Divide the expression by the #'s outside the ()

2-2x+x+5>_-3                     This is the quotient from dividing it by -8 (-2 and -4)

(when you divide by a negative number, the signs flip)

7-x>_-3                                Now, divide both sides by 7

-x>_-3/7                              If you want, convert to a decimal. Lastly, divide by -1

x>_3/7

Answer:

AB

Step-by-step explanation:

A ray has one endpoint and the rest is a line, so AB would be the only answer that would make sense in this situation (because it's starting from A and B is a point on the ray).

Answer: C=(44,29).

Step-by-step explanation:

The given points are A = (-4 , -7)  and B = (12 , 5).

It is given that Point B is 1/3 of the way from A to C.

AB:AC=1:3

AB:BC=AB:(AC-AB)=1:(3-1)=1:2

It means point B divides the line segment AC in 1:2.

Let coordinates of C are (a,b).

Section formula: If a point divides a line segment in m:n, then

[tex]Point=\left(\dfrac{mx_2+nx_1}{m+n},\dfrac{my_2+ny_1}{m+n}\right)[/tex]

Using section formula, we get

[tex]B=\left(\dfrac{1(a)+2(-4)}{1+2},\dfrac{1(b)+2(-7)}{1+2}\right)[/tex]

[tex](12,5)=\left(\dfrac{a-8}{3},\dfrac{b-14}{3}\right)[/tex]

On comparing both sides, we get

[tex]\dfrac{a-8}{3}=12[/tex]

[tex]a-8=36[/tex]

[tex]a=36+8[/tex]

[tex]a=44[/tex]

[tex]\dfrac{b-14}{3}=5[/tex]

[tex]b-14=15[/tex]

[tex]b=15+14[/tex]

[tex]b=29[/tex]

Therefore, the coordinates of C are (44,29).

Answer:

The humpback whales are 37 times bigger than the krills they eat

Step-by-step explanation:

In this question, we are interested in knowing how much bigger are humpback whales compared to krill.

what is simply happening here is to divide the weight of the humpback whales by the weight of the krills.

From the question, weight of humpback whales = 8 * 10^4 while the weight of the krills are 2.1875 * 10^3

So the number of times the humpback whales are bigger is;

(8 * 10^4)/(2.1875 * 10^3) = 36.57 which are approximately 37 times bigger

Answer:

An adult Welsh Corgi is always going to be shorter than an adult Basset Hound.

Step-by-step explanation:

That's what I think because the Basset Hound is 13.8 in. in height right? So he's two inches taller if we round up both numbers. Basset hound would be 14 and welsh corgi would be 11....................okay im not sure i give up but it's either

"An adult Welsh Corgi is always going to be shorter than an adult Basset Hound."

"Basset hounds tend to be a little over two inches taller than Welsh Corgis, but have a higher variability in height.

whichever just not the other ones good luck!

Basset hounds tend to be a little over two inches taller than Welsh Corgis, but have a higher variability in height.

Mean is actually the average of all the observations.

Basset hounds tend to be a little over two inches taller than Welsh Corgis, but have a higher variability in height.

of a data set is the average distance between each data value and the mean.

According to the problem,

Here we can say, the average height of Basset hounds is 13.8 and is highly dispersed in comparison to Welsh Corgis

So, we can say Basset hounds tend to be a little over two inches taller than Welsh Corgis, but have a higher variability in height.

Answer:

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

Step-by-step explanation:

Given

[tex]\frac{3}{2}[/tex](4x - 2) - 3x = 5 - (x + 2) ← distribute parenthesis on both sides

6x - 3 - 3x = 5 - x - 2 , that is

3x - 3 = 3 - x ( add x to both sides )

4x - 3 = 3 ( add 3 to both sides )

4x = 6 ( divide both sides by 4 )

x = [tex]\frac{6}{4}[/tex] = [tex]\frac{3}{2}[/tex]

Answer:

≈ 6 units

Step-by-step explanation:

Calculate the distance d using the distance formula

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = F(2, 11) and (x₂, y₂ ) = G(5, 16)

d = [tex]\sqrt{(5-2)^2+(16-11)^2}[/tex]

   = [tex]\sqrt{3^2+5^2}[/tex]

   = [tex]\sqrt{9+25}[/tex]

   = [tex]\sqrt{34}[/tex] ≈ 6 ( to the nearest whole number )

Answer:

8.06

Explanation:

For this question, you have to use the distance formula

Answer:

8.06

Step-by-step explanation:

To find the distance between two points, you would use the distance formula.

The distance formula is:

[tex]\sqrt{(x_2-x_1)^{2}+(y_2-y_1)^{2}}[/tex]

where (x₁, y₁) and (x₂, y₂) are two points.

Lets plug in the points (3, -1) (x₁, y₁) for  (7, -8) for (x₂, y₂):

[tex]\sqrt{(7-3)^{2}+((-8)-(-1))^{2}}[/tex]

= [tex]\sqrt{4^{2}+(-7)^{2}}[/tex]

= [tex]\sqrt{16+49}[/tex]

= [tex]\sqrt{65}[/tex]

≈ 8.06225775

Rounded to the nearest hundredth, it is 8.06.

So the distance between the points B and C rounded to the nearest hundredth is 8.06.
