How do you solve this equation: 18k - 4k = -10 -4k

Answers

18k - 4k = -10 - 4k
18k - 4k + 4k = -10
18k = -10
k= (18/10) = (9/5) = 1.8
18K-4k= -10-4K
18k-4k +4k =-10
18k18=-10/18
k=-.555556

Find the product of 21 and (6.3 • 10-4).

Answers

Answer:

1,239

Step-by-step explanation:

This problem can be rewritten as 21 • (6.3 • 10 - 4)

Following the order of operations (PEMDAS) we first have to solve what's in the parentheses.

The next letter is M for multiplication so we have to do 6.3 times 10 which makes 63. That makes 63 - 4 which is 59.

Lastly, since we finished the parentheses, we then do 21 • 59, which solves to be 1,239.

Choose the biconditional statement that could be based on the following: P → Q: If a quadrilateral is a parallelogram, then its opposite sides are parallel. Q → P: If its opposite sides are parallel, then a quadrilateral is a parallelogram. Question 1 options: A) P ↔ Q: A quadrilateral is a parallelogram if and only if its opposite sides are parallel. B) P ↔ Q: If a quadrilateral is a parallelogram, then its opposite sides are parallel. C) ∼P → ∼Q: If a quadrilateral isn't a parallelogram, then its opposite sides aren't parallel. D) P → P: If a quadrilateral is a parallelogram, then it's a parallelogram.

Answers

Answer:

A quadrilateral is a parallelogram if and only if its opposite sides are parallel AKA Q⇔P

Step-by-step explanation:

A biconditional statement puts a conditional statement in If and Only if form. it does not negate or switch the hypothesis or conclusion.

The symbol is q arrows going both ways (⇔) p

Identify the features of the graph

Answers

Answer:

Step-by-step explanation:

On seeing the graph we find that x intercepts are 1 and 5.

Also y intercept is 5

Vertex is at (3,-4) and also parabola is open up.

The possible equations can be of the form

y =a(x-1)(x-5)

y =a(x^2-6x+5)

When x=0, y =6

Hence 6 =5a

a =6/5

Solution is

y=(6)/(5) (x-1)(x-5)\n
There is a parabola that opens upwards with a line of symmetry at x=3 and the vertex is at (3, -4).

Find the product of 5+i and 4-i​

Answers

Answer:

21 - i

Step-by-step explanation:

( 5+i ) * ( 4-i )   = 5 * ( 4-i )  + i *( 4-i )

                      =   5*4 - 5*i + i*4 - i*i

                      = 20 - 5i + 4i - i²

                       = 20 - 5i +4i - (-1)                {  i² = -1 }

                       = 20 - 5i +4i + 1

                         = 21 - i
