The final cost of the items (before tax) if the $20 store bucks are applied before the 30% discount is $76.

The discount of 30% will be applied on $80 ($100 - $20), resulting to a discount of of $24 ($80 * 30%).

This discount is subtracted from the total value of the merchandise to get the final cost as $76 ($100 - $24).

Thus, the final cost to Leah to purchase the merchandise from the department store is $76.

Answer:

v=3

Step-by-step explanation:

SP and RQ are congruent, meaning that they are the same.

So, SP=RQ

We know that SP=5v and RQ=v+12

so plug those values into the equation

5v=v+12

then solve for v

4v=12

v=3

Answer:

regular polygon of 9 sides has 9 lines of symmetry

Answer:

See explanations below

Step-by-step explanation:

Given the polynomial function

P(x) = X^2+3x-10

To check whether x-2 and x+5 are factor, we will find x and then show that P(x) = 0

For x-2

x - 2 = 0

x =2

P(2) = 2²+3(2)-10

P(2) = 4+6 -10

P(2) = 10-10

P(2) = 0

Since the remainder is zero, hence x-2 is a factor of the polynomial

Similarly for x+5;

x+5 = 0

x = -5

P(-5) = (-5)²+3(-5)-10

P(-5) = 25-15-10

P(-5) = 10-10

P(-5) = 0

This also shows that x+5 is a factor

The shape which has parallel lines and at least one acute angle is; Choice C.

From definition, an acute angle is one whose angle measure is less than 90⁰.

Additionally, parallel lines are lines which can never intersect one another.

Therefore, from the definitions above, it follows that the required shape is; Choice C.

Answer:

418cm³

Step-by-step explanation:

volume of cuboid=l×b×h=11×2×19=418c³

Answer:

418 square centimeters.

Step-by-step explanation:

Since the formula for volume is length times width times height, you would have to multiply 11 (length) times 2 (width) first, and you would get 22. Next, you have to multiply 22 with the height (19). After you do this you will get your final answer which is 418 square centimeters.

4) add both.

x=8. y=-24

5) multiply 2.

6x+10y=108.

subtract.

6y=36.

y=6.

x=8.

-3(8)-24=0. correct.

3(8)+5(6)=54. Correct.

6(8)+4(6)=72 correct.

Hey there!

Given the following system:

4x + y = 8

-3x - y = 0

We do not need to change the equations at all, because the "y"s will already cancel eachother out. When we add the equations together, we get

x = 8

Now, we have to solve for y: We can do so by plugging in the value of x in to one of the equations:

4(8) + y = 8

Now we solve:

4(8) + y = 8

  32 + y = 8

           y = -24

The solution to the first given system is (8, -24)

Now, we can check by plugging the numbers into both equations, and seeing if they are true:

4(8) + (-24) = 8

 32 + (-24) = 8

                8 = 8 ~ TRUE

Now, we check the second equation:

-3(8) - (-24) = 0

 -24 - (-24) = 0

    -24 + 24 = 0

0 = 0 ~ TRUE

Both equations are true, which means that the correct solution to the first given system is (8, -24)

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

For the second given system, we are going to have to change one of the equations because, when added, the "x" or "y" values will not cancel out.

3x + 5y = 54

6x + 4y = 72

We can divide the second equation by -2 so the "x" values will cancel out:

-3x - 2y = -36

Now, we add the equations:

3y = 18

And solve for "y":

3y = 18

 y = 6

Now, we plug the "y" value into one of the equations and solve for "x":

3x + 5(6) = 54

 3x + 30 = 54

          3x = 24

             x = 8

The solution to the second given system is (8, 6)

Now, we can check by plugging the "x" and "y" values into both equations:

3(8) + 5(6) = 54

    24 + 36 = 54

             54 = 54 ~ TRUE

Now, we check the second equation:

6(8) + 4(6) = 72

    48 + 24 = 72

             72 = 72 ~ TRUE

Both equations are true, which means that the correct solution to the second given system is (8, 6)

She began with 20.

If she bought 7 more books and ended up with 17, that means she had ten beforehand. If she had half remaining, we simply double it, thus getting 20.

Answer:

P(-2) = 2(-2^4) - 5(-2^3) + (-2) -10

= 2(16) - 5(-8) + (-2) - 10

= 32+40-2-10

= 60

P(1) = 2(1^4) - 4(1^3) + (1) - 10

= 2 - 4 + 1 - 10

= -11

P(2). = 2(2^4) - 5(2^3) + (2) - 10

= 2(16) - 5(8) + 2 - 20

= 32-40+2-10

= -20

Require

Solve for [tex]\angle 1, \angle 2, \angle 3, \angle 4[/tex]

We start by solving for [tex]\angle 1[/tex]

[tex]\angle 1 + 79 = 180[/tex] ---- Angle on a straight line

[tex]\angle 1 + 79-79 = 180 - 79[/tex] --- Subtract 79 from both sides

[tex]\angle 1 = 101[/tex]

[tex]\angle 1 = \angle 2 = \angle 3[/tex] --- Corresponding angles;

So, we have:

[tex]\angle 2 = 101[/tex]

[tex]\angle 3 = 101[/tex]

[tex]\angle 1 = \angle 4[/tex] --- vertically opposite angles

So, we have:
