Point M is the midpoint of segment JK. Find JK when JM=6x-7 and MK=2x+3.
Whitepunk [10]
If M is the midpoint of JK then JM+MK=JK and JM=MK
so
6x-7=2x+3
minus 2x both sides
4x-7=3
add 7 both sides
4x=10
divide both sides by 4
x=\frac{10}{4}
x=\frac{5}{2}

sub back

JM=6x-7
JM=6(\frac{5}{2})-7
JM=\frac{30}{2}-7
JM=15-7
JM=8

JM=MK=8
JM+MK=8+8=16=JK

x=\frac{5}{2} and JM=8=MK and JK=16

This year ⅗ of the students in Fionna’s class identify as girls. Fionna notices that ⅔ of these girls wear braces. Only ½ of the
Tju [1.3M]

Answer:

³/5

Step-by-step explanation:

Total = 5 units

Girls = 3 units

~if ⅔ of the girls wear braces

= 2units of girs wear braces

Boys = 2 units

~if ½ of the boys wear braces

= 1unit of boys wear braces

Hence, 2units + 1unit =3 units of the class wears braces.

Total pupils = 5units

total that wear braces out of the whole class = 3/5

Use the functions f(x)=7x3−3x2−x+14 f x = 7 x 3 - 3 x 2 - x + 14 and g(x)=2x3+2x+5 g x = 2 x 3 + 2 x + 5 as examples to show tha
Aneli [31]

Answer:

<h3>The given set of polynomials f(x) and g(x) are closed under subtraction.</h3>

Step-by-step explanation:

Given that the functions f ad g are defined by

f(x)=7x^3-3x^2-x+14 and g(x)=2x^3+2x+5 respectively.

<h3>To  show that the set of polynomials is closed under subtraction :</h3>

Now subtract the given polynomials

f(x)-g(x)=(f-g)(x)

=7x^3-3x^2-x+14-(2x^3+2x+5)

=7x^3-3x^2-x+14-2x^3-2x-5

=5x^3-3x^2-3x+9

∴ f(x)-g(x)=5x^3-3x^2-3x+9

  • When subtracting the polynomials the variables and their exponents remains same only variation in their coefficients.
<h3>Hence the given polynomials f(x) and g(x) are closed under subtraction.</h3>

∴ f(x)-g(x)=5x^3-3x^2-3x+9 are closed under subtraction,

Hence showed.
