Answer:

(-4,-5) (-3,-3)

Step-by-step explanation:

[tex](-4,-5),(-3,-3)[/tex]

Given equation is [tex]y=2x+3[/tex]

Put [tex](x,y)=(-4,-5)[/tex]

[tex]-5=2(-4)+3\\-5=-5[/tex]

Put [tex](x,y)=(-3,-3)[/tex]

[tex]-3=2(-3)+3\\-3=-3[/tex]

Put [tex](x,y)=(-1,0)[/tex]

[tex]0=2(-1)+3\\0\neq 1[/tex]

Put [tex](x,y)=(-1,-4)[/tex]

[tex]-4=2(-1)+3\\-4\neq 1[/tex]

So, [tex]\boldsymbol{(-4,-5),(-3,-3)}[/tex] lie on the graph [tex]y=2x+3[/tex]

Answer:

0.4

Step-by-step explanation:

The numbers -3.5 and -3.1 have a difference in value of 0.4

An easy way to look at this is to remove the decimal points. 35 - 31 is equal to 4, so that would make the difference 0.4.

Because both numbers are negative, the x must be a positive.

Therefor, 0.4 - 3.5 = -3.1

Answer:

  Pears:  30

Step-by-step explanation:

Constant:

  3x + 5x + 2x = 150

                 10x = 150

                    x = 15  

Multiply ratio with constant from above:

  oranges : apples

       3 * 15 : 5 * 15

            45 : 75       ==>               45 oranges: 75 apples

  pears : apples

   2 * 15 : 5 * 15

        30 : 75          ==>                    30 pears: 75 apples

Check:

45 oranges + 75 apples + 30 pears = 150 fruits

Given:

a = 2 and b = -2.

To find:

The value of [tex]a^3+3b^2[/tex].

Solution:

We need to find the value of expression [tex]a^3+3b^2[/tex] at a = 2 and b = -2.

Substituting a = 2 and b=-2 in [tex]a^3+3b^2[/tex], we get

[tex](2)^3+3(-2)^2[/tex]

[tex]=8+3(4)[/tex]

[tex]=8+12[/tex]

[tex]=20[/tex]

Therefore, the value of expression [tex]a^3+3b^2[/tex] at a = 2 and b = -2 is 20.

Answer:

5 and 6 and -1

6 and 8 and -4

5 and 8 and -2 and -1

Step-by-step explanation:

They all add up to 10.

The trick is to first figure out if you can combine 5 6 or 8 together, then use the negative numbers to subtract as needed to reach you number. If you add 5 and 6, that is 11, but -1 can make 10. When you add 8 and 6, that is 14. But good thing you have the -4 to make 10. You start with the smallest number found from adding together two numbers from the positive pile like 5 and 6.

You can make other combinations as well. 11 could work too.

The pairs of cards are  (-4, 8), (-1, 5) and (-2, 6) respectively.

Addition is a mathematical operation which used to count the things when are together. The addition of two positive integers are greater than both of them while for negative integers it is less than both of them.

Given that,

The different cards having numbers on them are as below,

-4, -2, -1, 5, 6, 8.

In order to select them into three pairs having the same sum make the pair as follows,

Add each positive number to each of the negative numbers and then select the pair of numbers having the same sum.

Thus, it is obtained as,

-4 + 8 = 4

-1 + 5  = 4

-2 + 6 = 4

Hence, the required pairs of cards are (-4, 8), (-1, 5) and (-2, 6) respectively.

Answer:

It took Pedro  3.81 hours to reach the lake.

Step-by-step explanation:

Time taken by Mike to hike a lake = 4.5 hours

Average rate of Mike while hiking the lake = [tex]2\frac{1}{5}\ miles/hr[/tex]

Formula for distance can be seen as:

[tex]Distance = Speed\times Time[/tex]

Distance traveled by Mike = [tex]4.5 \times 2\frac{1}{5} = 4.5\times \frac{11}{5} = 9.9\ miles[/tex]

Rate of Pedro while hiking the same distance = [tex]2\frac{3}{5}\ miles/hr = \frac{13}{5}\ miles/hr[/tex]

Given that, Pedro also travels the same distance.

And we have to find the Time.

[tex]Time = \dfrac{Distance}{Speed}[/tex]

[tex]Time = \dfrac{9.9}{\frac{13}{5}}\\\Rightarrow Time = \dfrac{9.9\times 5}{13} = \bold{3.81\ hours}[/tex]

It took Pedro  3.81 hours to reach the lake.

Answer:

okay so I am assuming we are dividing okay so here is how we will do it

here are the top and bottom values written more easily

3^n -3^n-1

3^n+1 +3^n

so first we can cancel out the 3^n values then get left with this

3^n-1

3^n+1

now it depends on the instructions but you can leave it like this or you can subtract their powers to get

Answer:

the number of seconds that you and your friend would be have the similar distance from the starting line is 20 seconds

Step-by-step explanation:

The computation of the number of seconds that you and your friend would be have the similar distance from the starting line is shown below:

As we know that

Speed = Distance ÷ Time

SO,

Time = Distance ÷ speed

= 10 meters ÷ difference in speed

= 10 meters ÷ (6 meters per second - 5.5 meters per second)

= 10 meters ÷ 0.5 meters per second

= 20 seconds

hence, the number of seconds that you and your friend would be have the similar distance from the starting line is 20 seconds

We are told that 40% of the customers who bought groceries also bought a bag of ice.

The total customers is 160 customers

Required.

the number of customers that bought a bag of ice?

Step two:

Let us compute what 40% will amount to

40/100*160

=0.4*160

=64

Hence 64 customers bought rice

Answer:

∠GEF = 25

Step-by-step explanation:

Here, we want to find the value of the marked angle

Please check the attachment for the diagrammatic representation of the triangle

Mathematically, the sum of opposite interior angles equals the exterior angle

We can have this sum as follows;

∠EFG + ∠GEF = ∠FGH

Thus;

2x + 1 + x + 19 = 6x + 2

3x + 20 = 6x + 2

6x-3x = 20-2

3x = 18

x = 18/3

x = 6

Now , substitute x into the ∠GEF

That will be;

6 + 19 = 25
