f(x)=-6x-8, what if f(-3)

Answers

Answer 1

Answer:

f(-3) = 10

Step-by-step explanation:

Simply plug in x as -3 to find f(-3):

f(-3) = -6(-3) - 8

f(-3) = 18 - 8

f(-3) = 10

If g(x) = – 3x + 2, find g(–4).

Answers

G (x) = G (-4)
First plug in -4 to all the x’s
G(-4)= -3(-4) + 2
Next, you solve it. We start with multiplication.
G(-4)= 12+2
Finally, add 12 + 2.
G(-4)=14
If this isn’t the answer, you can go deeper into the problem by finding the value of G.
We can do this by getting G by itself.
G(-4)=14
We can get G by itself, by dividing.
G(-4)=14

Need help on this question please

Answers

Answers:x = 13 and y = 11

===========================================================

Explanation:

Check out the diagram below. I've added in the label (4x+13) degrees to the angle adjacent to the (9x-2) degree angle. This is valid due to corresponding angles being congruent when we have parallel lines like this.

The two angles form a 180 degree straight angle

(4x+13) + (9x-2) = 180

4x+13 + 9x-2 = 180

(4x+9x) + (13-2) = 180

13x + 11 = 180

13x+11-11 = 180-11 .... subtracting 11 from both sides

13x = 169

13x/13 = 169/13 .... dividing both sides by 13

x = 13

We can verify this by noticing that

4x+13 = 4*13+13 = 65

9x-2 = 9*13-2 = 115

So, (4x+13)+(9x-2) = (65)+(115) = 180, showing the two angles are supplementary.

-----------------

The angles (9x-2) and (6y-1) are also a linear pair. They are adjacent and supplementary

Let's use x = 13 to find the value of y

(9x-2) + (6y-1) = 180

9x-2+6y-1 = 180

9x+6y-3 = 180

9*13+6y-3 = 180 .... plug in x = 13

117+6y-3 = 180

6y+114 = 180

6y+114-114 = 180-114 .... subtract 114 from both sides

6y = 66

6y/6 = 66/6 ...... divide both sides by 6

y = 11

To help confirm,

6y-1 = 6*11-1 = 65

which adds onto the (9x-2) = 115 degree angle to get 180.

-----------

Side note: as an alternative, you can solve 4x+13 = 6y-1 to get the same y value. This is because alternate exterior angles are congruent when we have parallel lines like this.

Please help me! Find the sale price

Answers

Answer:

sale price is $104

Step-by-step explanation:

Given the equation in the problem S=P-0.20P:S = P - 0.20PS = (130.00) - (0.20 · 130.00)S = 130-26S = $104

Answer:

$104.00

Step-by-step explanation:

So we know that in the equation:

S = P - 0.20P

P is the original price and S is the sale price, which is also the original price reduced by 20%.

We are also given that the original price of a digital media player is $130.00.

We are asked to find the sales price of that digital media player. To do this, we can plug in $130.00 for P in the given equation, since it is the original price of the digital media player, and solve for S, the sales price:

S = 130 - (0.20)(130)

S = 130 - 26

S = 104

So now we found the sales price of the digital media player, which is $104.00.

Answers

The maximum number of text messages that you can send or receive next month Next month, you can send or receive up to 45.54 text messages in total.

What is maximum in mathematics?

In mathematics, a point at which a function's value is greatest. If the value is greater than or equal to all other function values, it is an absolute maximum. If it is merely greater than any nearby point, it is a relative, or local, maximum

Considering the information provided;

Given that the monthly expense is $34.99

and $0.11 for each text as well (sent or received)

Suppose y is the whole cost.

Set x as the quantity of text.

The test messages make up the difference between the cost of the plan and the $40 you must spend, which is represented by the equation

4034.99=5.01

in the model for the overall cost,

y=34.99+0.11x.

Count the number of messages you can send, you must divide.

5.01÷0.11

=45.54

The maximum number of messages is 45
