at 30 mph and Andrew travels due south at
40 mph. If nothing causes either to stop for
any reason how far apart are they after
1 hour?

Answer:

x+8z-9y-ty

2x+5z-9y + x-8z+9y+ty

=3x+ty-3z

Answer: The quantity a plus b doubled

               Twice the quantity of a and b

Step-by-step explanation: You're multiplying the sum of a and b by two. Multiplying by two and doubling is the same. Twice is a synonym for two times. there is no addition happening that involves 2 and there is no subtraction with a and b so the second and fourth choice are eliminated.

Slope formula - [tex]\frac{y2-}{x2-} \frac{y1}{x1}[/tex]

First coordinate pair - (-1, -4)

Second coordinate pair - (3, 1)

Coordinate format - (x, y)

y2=1, y1=-4

x2=3, x1=-1

[tex]\frac{1-}{3-} \frac{(-4)}{(-1)} =\frac{5}{4}[/tex]

Hope this is what your looking for :)

the slope goes by several names

• average rate of change

• rate of change

• deltaY over deltaX

• Δy over Δx

• rise over run

• gradient

• constant of proportionality

I have attached an image of the graph of this inequality from Desmos, a virtual graphing website to help answer your question.

However, to explain this graph, each and every x value less than or equal to 5 would be an appropriate solution to the inequality, thus all values less than or equal to 5 are shaded in.

Answer:

156cm

470+30+8=508cm

780+90+7=877cm

560+40+8=608cm

Step-by-step explanation:

After simplifying the expression (1 / 2 + 3 / 8) × 8 , we get the result as 7.

We are given the expression:

(1 / 2 + 3 / 8) × 8

We need to evaluate the expression.

For this, we will use the rule of BODMAS.

So, first, we will solve the brackets and add the numbers.

So, we get that:

(1/2 + 3/8) × 8

= ( 4 / 8 + 3 / 8 ) × 8

= ( 7 / 8 ) × 8

Now we will multiply to get the value of the expression:

= 7

Therefore, after simplifying the expression (1 / 2 + 3 / 8) × 8 , we get the result as 7.

16)

 [tex]\frac{4}{10} , \frac{32}{72}\\\\\frac{4}{10} = \frac{32}{72}[/tex]

Cross multiply,

4 * 72   = 32 * 10

  288   ≠   320

So, these are not in proportion.

17)

[tex]\frac{40}{25} = \frac{32}{20}[/tex]

Cross multiply,

40 * 20 = 32 * 25

800  = 800

So, these are in proportion.

[tex]\frac{15}{45}=\frac{9}{c}[/tex]

Cross multiply,

      c = 9*3

     c = 27

Answer:

Step-by-step explanation:

<1 is the supplement of 5x + 5.  You have to assume that the almost horizontal lines are parallel. In addition, two angles on the same side of a transversal across two parallel lines and are interior angles are supplementary.

5x + 6 + 7x - 18 = 180                   Add  like terms

12x - 12 = 180                                Add 12 to both sides

12x = 180 + 12

12x = 192                                      Divide by 12

x = 192 /12

x = 6

====================

5x + 6 = 5*12 + 6

5x + 6 = 60 + 6

5x + 6 = 66

<1 + 66 = 180

<1 = 180 - 66

<1 = 114

No, because the amount of money on her gift card should decrease each week.

Step-by-step explanation:

Well, the graph shows that the slope is increasing, if you got $50.00 and spend $6.00 each Friday, wouldn't that be  decrease and not increase? This is why we eliminate the yes options. Lastly, of course, they should not start at the origin as they started at $50.00.

To know if the answer is rational or irrational, check to see if they can be turned into a fraction.

Answer:

4) [tex]\sqrt{25}[/tex]

5) [tex]\pi[/tex]

Step-by-step explanation:

4) [tex]\pi[/tex] is irrational.

[tex]\sqrt{2}[/tex] and [tex]\sqrt{3}[/tex] are also irrational.

[tex]\sqrt{25}[/tex] = 5. 5 is a whole number and thus is rational.

5) 16.5% = [tex]\frac{16.5}{100}[/tex]

0.0675 is a terminating decimal so it is rational.
