P.S, I solved this problem graphically. If you have any problems, please write them in the comments.

Explanation:

To find the value of k (y-intercept of 2nd line), we will need to draw a graph. Please check out the uploaded graph. In the graph, it tells us that the y-intercept of 2nd line is 1.

Hence, the value of k is 1.

Answer:

example: find lcm of 48 and 32

48: 48, 96, 144, 192

32: 32,64,96,128,160,192

Step-by-step explanation:

list multiples and then find the smallest number that is both their multiple. That is Lcm

Step-by-step explanation:

the lowest common multiple of 2 numbers.

I recommend prime factorization.

starting with 2 you divide each number by lowest possible prime factor as many times as possible without remainder.

then you go to the next higher prime number and keep dividing without remainder.

and the next and the next until you reach 1 as the remaining number.

and then you combine (multiply) the longest streaks per prime number.

the result : the LCM

example :

98 and 36

98

2 49 (no more 2 division, 3 does not work, 5 does not work, but 7)

7 7

7 1

36

2 18

2 9

3 3

3 1

so, the longest streaks per prime number are

2×2 = 4

3×3 = 9

7×7 = 49

and the LCM = 4×9×49 = 1764

The quadratic regression equation for this data set is [tex]\rm y=-0.143x^2+0.59x+2.82\\[/tex].

The general form of the quadratic equation is given by;

[tex]\rm ax^2+bx+c=0[/tex]

Where; a, b, and c are the constants.

x;   0       1         2        3          4         5

y;  2.82  3. 29  3. 46  3. 33   2. 88  2. 24

From the table when the value of x = 0 the value of y is 2.82.

Then,

[tex]\rm y=ax^2+bx+c\\\\x=0\\\\2.82=a0^2+b(0)+c\\\\c=2.82[/tex]

From the table when the value of x = 3 the value of y is 3.33.

[tex]\rm y=ax^2+bx+c\\\\x=3\\\\2.82=a(3)^2+b(3)+c\\\\9a+3b+2.82=2.82\\\\9a=-3b\\\\b=-3a\\\\[/tex]

From the table when the value of x = 5 the value of y is 2.24.

[tex]\rm y=ax^2+bx+c\\\\x=3\\\\2.24=a(5)^2+(-3a)(5)+c\\\\25a-15a+2.82=2.24\\\\40a=2.24-2.82\\\\10a=-0.68\\\\a= \dfrac{-0.68}{10}\\\\a=-0.143[/tex]

And the value of b is;

[tex]\rm b=3a\\\\b=3(-0.14)\\\\b=0.59[/tex]

Therefore,

The quadratic regression equation for this data set is;

[tex]\rm y=ax^2+bx+c\\\\y=-0.143x^2+0.59x+2.82\\\\[/tex]

Hence, the quadratic regression equation for this data set is [tex]\rm y=-0.143x^2+0.59x+2.82\\[/tex].

Step-by-step explanation:

Note:

Important:

What was the old price of the shoes

Solution:

40.60 x .16 = 6.946 [Round:6.50]

40.60-6.50= 34.10

Hence, the old price of the shoes is $34.10

Answer:

no

Step-by-step explanation:

using the values of the ordered pair in the first equating we get :

2 = 3×5 - 13 = 15 - 13 = 2

that fits.

but when using them in the second equation we get :

4×5 - 3×2 = 17

20 - 6 = 17

14 = 17

and that is wrong.

that means the point (5, 2) is not on the second line, so the point cannot be the crossing point (= solution, where both equations deliver the same result) of both lines.

FYI

we would solve the system by using the first equality directly in the second equation :

4x - 3(3x - 13) = 17

4x - 9x + 39 = 17

-5x = - 22

5x = 22

x = 22/5 = 4.4

and y is then

y = 3×4.4 - 13 = 13.2 - 13 = 0.2

the actual solution of the system is therefore

(4.4, 0.2)

A triangle is isosceles triangle when the two sides and two angle of the triangle in equal in measure.

The approximate total area of the plastic triangles on the spinner is 7.7 squared centimetre.

A triangle is isosceles triangle when the two sides and two angle of the triangle in equal in measure.

The area of the isosceles triangle is given as,

[tex]A=\dfrac{1}{2}\times b\times \sqrt{a^2-\dfrac{b^2}{4} }[/tex]

Here, [tex]a[/tex] is the measure of equal sides and [tex]b[/tex] is the measure of third side.

Given information-

The arrows of board game are congruent isosceles triangles connected at their bases.

isosceles triangles are connected at their bases.

The base of each triangle measures 2 centimetres

The perimeter of each triangle is 10 centimetres.

The perimeter of a triangle is sum of all its sides.

As the given triangle is isosceles triangle. Thus both the sides of the triangle should be equal.

Suppose the equal sides is x centimetres. The measure of third side is given which is equal to 2 centimetres. Thus,

[tex]x+x+2=10\\2x=10-2\\2x=8\\x=\dfrac{8}{2} \\x=4[/tex]

Hence the length of the equal sides of the isosceles triangle is 4 cm.

Using the above formula as,

[tex]A=\dfrac{1}{2}\times b\times \sqrt{a^2-\dfrac{b^2}{4} }\\A=\dfrac{1}{2}\times 2\times \sqrt{4^2-\dfrac{2^2}{4} }\\A= \sqrt{16-\dfrac{4}{4} }\\A=3.871[/tex]

Hence the area of one plastic arrow triangle is 3.71 square centimetre. The approximate total area of the plastic triangles on the spinner is twice of it. Thus,

[tex]A=3.71\times2\\A=7.7[/tex]

Thus the approximate total area of the plastic triangles on the spinner is 7.7 squared centimetre.
