Answer:

1) 5\times y-2xy=y(5-2x)

2) 4q + 2q - 6=6(q-1)

Step-by-step explanation:

1) 5\times y-2xy

In both terms given in an expression has common variable of 'y', so we can take that common.

The expression will be written as:

5\times y-2xy=y(5-2x)

2) 4q + 2q - 6

In two terms out of three in an expression has common variable of 'q', so we can take that common.

The expression will be written as:

4q + 2q - 6=2q(2+1)-6

=2q(3)-6

=6q-6

4q + 2q - 6=6(q-1)

Answer:

5y-2xy

6q-6

Step-by-step explanation:

For the first expression, we can multiply 5 by y to get 5y. Thats all we can simplify it though, because xy is not equal to x or y.

For the second equation, we can easily add the variables to simplify. 6q-6

Hope this helps!

Help I keep getting an answer that is not an option
horsena [70]

Answer:

6600

Step-by-step explanation:

y = 15000( 1.2) ^ (x/3)

Let x = 6 years

y = 15000( 1.2) ^ (6/3)

y = 15000( 1.2) ^ (2)

y = 15000( 1.44)

y =21600

This is the total amount in the account

We want the profit

Subtract the original amount in the account

21600-15000

6600

ASAP IM BEING TIME PLEASE!!

x° = 14°, y° = 14°; Use vertical and supplementary angles.

Step-by-step explanation:

The image of the answer is attached below.

In the given image two lines are parallel with transversal.

(9x + 12)° and ∠1 are vertically opposite angles.

Vertically opposite angles are equal.

∠1 = (9x + 12)°

Consecutive interior angles are supplementary.

(9x + 12)° + 3x° = 180°

⇒ 12x° = 168°

⇒ x° = 14°

Sum of the adjacent angles in a line are supplementary.

3x° + (4y – 10)° = 180°

⇒ 3(14)° + 4y° – 10° = 180°

⇒ 4y° = 148°

⇒ y° = 14°

Hence, x° = 14°, y° = 14°; Use vertical and supplementary angles.

F(x) = -7x2 + 9x - 15 and g(x) = -12x2 – 15x + 7
djyliett [7]

Answer:

{5x}^{2}  + 6x =  - 8

Step-by-step explanation:

This question is asking you to insert two equations, f(x) and g(x), into the equation g(x) - f(x). This will lead to the equation below.

{ - 12x}^{2}  - 15x + 7 - ({ - 7)x}^{2}  + 9x - 15

Now we can solve for the equation.

{ - 5x}^{2}  - 6x - 8 = 0 \\   {5x}^{2}  + 6x =  - 8

Out of the 150 students at a summer camp, 72 signed up for canoeing. there were 23 students who signed up for trekking, and 13 o
True [87]

Answer:

Approximately 45% students signed up for neither canoeing or trekking.

Step-by-step explanation:

First we subtract the number of the students who signed up from the number of the total students to find the number of the students who did not signed up for either.

But there are 13 students who signed up canoeing and also for trekking.

Hence the number of students they signed up for activity is

72 + 23 - 13 = 82

And the number of students they not signed up for any activity is

150 - 82 = 68

so 68 students signed up neither for trekking nor canoeing. The percentage of those students are :

\frac{68}{150} × 100 = 45.3333%

Approximately 45% students signed up for neither canoeing or trekking.
