If a = i - 9k and b = j + k , find ab .

Orlov [11]

Answer:

solution

given a=1_9k and b=j+k

Now,ab=(1_9k)(j+k)

=1((j+k)-9k(j+k)

=j+k_9jk-9k^2

=k_9k^2+j_9jk

=k((1_9k)+j(1_9k)

=(1_9k)(k+k)

Solve using elimination<br><br> 2x+5y=34<br> x+2y=14

Darina [25.2K]

2x + 5y = 34

x+2y = 14

Multiply the second equation by two to create like terms for one variable.

2(x+2y = 14)

2x + 4y = 28

2x + 5y = 34

2x + 4y = 28 -- Subtract.

y = 34.28 = 6

Solve for x

x + 2(6) = 14

x + 12 = 14

x = 2

Check:

2 + 2(6) = 14

2 + 12 = 14

14 = 14

Answer:

X = 2

Y = 6

What is the difference of the fractions? Use the number line to help find the answer.

Vedmedyk [2.9K]

Answer:

-11/20

Step-by-step explanation:

$\frac{1}{5} - \frac{3}{4} = \frac{?}{?}$

first you want to get a common denominator (number on the bottom)

$\frac{4}{20} - \frac{15}{20} = \frac{?}{?}$

now you can subtract the numerators (number on tope) (also don't touch bottom)

$it ~equals = -\frac{11}{20} ~~because ~4-15 ~is -11$
