What is the value of x in the equation –2.4x = 8.4?
1. –20.16
2. –3.5
3. 3.5
4. 20.16

Answers

Answer 1

Answer:

2. -3.5

Steps:

divide both sides by by (-2.4): -2.4x ÷ (-2.4) = 8.4 ÷ (-2.4)

any equation divided by itself equals 1 so that would be the right side: x = 8.4 ÷ (-2.4)

divide the equation on the left and get: x = -3.5

RS bisects TU at Q. If TQ=5k-9 and QU=15-x

Answers

Answer:

x = 4, TU = 22

Step-by-step explanation:

Given that TS bisects TU at Q , then

TQ = QU , substitute values

5x - 9 = 15 - x ( add x to both sides )

6x - 9 = 15 ( add 9 to both sides )

6x = 24 ( divide both sides by 6 )

x = 4

Thus

TU = 5x - 9 + 15 - x = 4x + 6 = 4(4) + 6 = 16 + 6 = 22

Given f(x) = | – 5 – 4x| ,find the following:

f(12) =

f(2)=

Answers

Answer:

[tex]f(10) = 35 \\ \\ f( - 11) = 39 \\ \\ f(12) = 53 \\ \\ f(2) = 13[/tex]

Step-by-step explanation:

[tex] f(x) = | - 5 - 4x| [/tex]

To solve for the following substitute the value of x in the brackets into the above formula and solve for the value of x

NB: Absolute value of a negative number is the same number but positive.

So we have

[tex]f( - 10) = | - 5 - 4( - 10)| \\ = | - 5 + 40| = 35 \\ \\ f( - 11) = | - 5 - 4( - 11)| \\ = | - 5 + 44| = 39 \\ \\ f(12) = | - 5 - 4(12)| \\ = | - 5 - 48| \\ = | - 53| = 53 \\ \\ f(2) = | - 5 - 4(2)| \\ = | - 5 - 8| = | - 13| \\ = 13[/tex]

is this a right triangle?

Answers

The only way to really tell is to check it with the Pythagorean Theorem.

The Pythagorean Theorem describes every right triangle, and every triangle that fits the Pythagorean Theorem has a right angle in it.  Guaranteed.  This is incredibly handy.

If this IS a right triangle, then

(one leg squared) + (the other leg squared) = (the hypotenuse squared) .  

Let's check it out:

--  One leg squared = (11 cm)²  .  That's  121 cm² .

--  The other leg squared = (√99 cm)² .  That's  99 cm²  .

--  Their sum is  (121 + 99) cm² .  That's  220 cm² .

-- The hypotenuse squared is  (15 cm)² .  That's  225 cm² .

Is  220 cm² equal to  225 cm² ?

NO !  They are not equal.  They are different !

The sum of the squares of the legs is NOT equal to the square of the hippopotamus.

==>  This triangle does NOT fit the Pythagorean Theorem.

==>  It is NOT a right triangle.

(The angle in the bottom corner is slightly bigger than 90°.  But you can't tell by looking at it.  It's so close that you can only tell by checkoing the lengths againt the Pythagorean Theorem.)

Answers

Answer:

1.    x = 1, y = 2.

12.  x = 1, y = -3.

Step-by-step explanation:

I won't do all these for you, just the first and the last. The method is similar  for all 12.

1.

y = x + 1

x + y = 3

Substitute y = x + 1 into the second equation:

x + y = 3 so:

x + (x + 1) = 3

2x + 1 = 3

2x + 1 -1 = 3 - 1

2x = 2

x = 1.

Now substitute x = 1 into the first equation to get the value of y:

y = x + 1

y = 1 + 1

y = 2.

12.

4x = y + 7

3x + 4y + 9 = 0

Solve for y in the first equation:

4x = y + 7                Subtract 7 from both sides of the equation:

4x - 7 = y + 7 - 7

y = 4x - 7.

Now substitute  y = 4x - 7 in the second equation:

3x + 4y + 9 = 0   so:

3x + 4(4x - 7) + 9 = 0

3x + 16x - 28 + 9 = 0

19x - 19 =  0

19x - 19 + 19 = 0 + 19

19x = 19

x = 19/19 = 1.

Now substitute x = 1 in the first equation:

4x = y + 7

4*1 = y + 7              Subtract 7 from both sides of the equation:

4 - 7 = y + 7 - 7      

-3 = y.

to simplify the equation, use the rainbow method,
5(t-1), we multiply 5 by t first to get 5t

Raj is deciding between two cell phone plans, A and B, which are both linear functions. The monthly charge for plan A according to the number of minutes used is shown in the table. Monthly Charge for Plan A Minutes used, x Monthly charge ($), y 0 14.45 3 14.84 6 15.23 9 15.62 12 16.01 Plan B has the same monthly base charge as plan A, but it charges a different amount per minute used. If the total monthly charge for plan B is $22.10 when 45 minutes are used, what is the slope of the linear function that represents the cost of plan B?

Answers

Answer:

B

Step-by-step explanation:

The slope of the linear function for plan B is of $0.17.

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

A linear function has an equation in the following format:

[tex]y = mx + b[/tex]

In which

m is the slope, which is the rate of change, measuring how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0.

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

Plan B has the same monthly base charge as plan A, that is, from the table, when [tex]x = 0, y = 14.45[/tex], and thus, (0, 14.45) is one of the points of the function.The monthly charge for 45 minutes is of $22.10, thus, another point is (45, 22.10).Given two points, the slope is given by the change in y divided by the change in x. Thus:

[tex]m = \frac{22.1 - 14.45}{45 - 0} = 0.17[/tex]

The slope is of $0.17.

Answers

The answer is $22.90


Solve using proportions.
Subtract when taking off money to the price.
And Add when adding more to the price

The total cost of the leash will be $22.90. The correct option is A.

What is the percentage?

The Percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that Kirk finds a dog leash with a price tag of $24 at a pet store. The leash is 10% off the original price. He must also pay 6% sales tax.

The cost after 10% off is:-

Cost = 24 - 24 x ( 10 / 100 )

Cost = 24 - 2.4

Cost = 21.6

Total cost after 6% sales tax = 21.6 + ( 21.6 x 0.06)

Total cost after 6% sales tax = 21.6 + 1.296 = $22.9

Therefore, the total cost of the leash will be $22.90. The correct option is A.
