Let the function f be defined by f(x) = 12-5x

What value of a will make the equation f(a) = 6 true?


6/5


-18


-13


5/6

Step-by-step explanation:

Hey there!

By looking through figure, l and m are parallel lines and a transversal line passes through the lines.

Now,

7x + 12° = 12x - 28°( alternate angles are equal)

12°+28° = 12x - 7x

40° = 5x

[tex]x = \frac{40}{5} [/tex]

Therefore, x = 8°

Now,

12x - 28° + 9y - 77 = 180° ( being linear pair)

12×8° - 28° + 9y -77° = 180°

96° - 28° + 9y - 77° = 180°

-9 + 9y = 180°

9y = 180° + 9°

y = 189°/9

Therefore, y = 21°

Therefore, X = 8° and y= 21° .

Hope it helps....

Step-by-step explanation:

Parallel lines have the same slope.

x -3y = 21

y = (21-x)/-3 ==== y = 1/3x -7

Substitute the values,

y = mx + c

5 = (1/3)(-6) + c

5 = -2 + c

c = 7

Thus, the equation is y = 1/3x + 7

An equation of the line that passes through the point (−6,5) and is parallel to the line x−3y=21 is y = 1/3x + 7.

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

We need to find an equation of the line that passes through the point (−6,5) and is parallel to the line x−3y=21.

Parallel lines have the same slope;

x -3y = 21

y = (21-x)/-3

y = 1/3x -7

Substitute the values;

y = mx + c

5 = (1/3)(-6) + c

5 = -2 + c

c = 7

Therefore, the equation is y = 1/3x + 7

=(−8)(4y)+(−8)(−5)

=−32y+40

Answer:

-32y + 40

Step-by-step explanation:

Again, multiply -8 by terms inside the parenthesis.

-8x4=-32y and -8 x -5= 40

= -32y + 40

Answer:

1

Step-by-step explanation:

So for this type of problem we use the formula [tex]m= \frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex] with each variable (besides m which is slope) representing a different coordinate. (e.g. -3 could be [tex]y_{2}[/tex] in this case.) First, let's define which is which:

(3,2): [tex]x_{1}, y_{1}[/tex]

(-2,-3): [tex]x_{2}, y_{2}[/tex]

Now we need to replace the variables with their known values: [tex]m=\frac{-3-2}{-2-3}[/tex]

Next, let's do the subtraction to simplify: [tex]m=\frac{-5}{-5}[/tex]

And we can complete the division (all fractions are division!) to simplify even further: [tex]m = 1[/tex]

Therefore, the slope of the line passing through the points (3,2) and (-2,-3) is 1.

Answer:

m=0.833333

Step-by-step explanation:

(1/16)−3m+1=64

log((1/16)−3m+1)=log(64)

(Take log of both sides)

(−3m+1)*(log(1/16))=log(64)

−3m+1=log(64)

log(1/16)

−3m+1=−1.5

−3m+1−1=−1.5−1

(Subtract 1 from both sides)

−3m=−2.5

−3m

−3

=

−2.5

−3

(Divide both sides by -3)

Answer:

4 bags of oranges

Step-by-step explanation:

First, we need to find out how much each bag of oranges costs so we divide.  

$4.20 divided by 6 equals 0.7 which means that each bag of oranges costs $0.70.

Next we need to find out how much Ayden spent on oranges so we divide 0.70 by 2.80

2.80 divided by 0.70 equals 4.

This means that Ayden bought 4 bags of oranges.

Hope this helps!

Answer:

4 oranges

Step-by-step explanation:

First find the unit rate by dividing the price of 6 oranges by the amount of oranges in the bag. So $4.20÷6=0.7. 0.7 is the price of one orange. Since the dollar amount is small I just divided $4.20 by 2 and got $2.10 for three oranges. The question is asking how much he bought for $2.80 so add another .70 which is one more orange therefore he bought 4 oranges for $2.80

Answer:

The fourth term is 11 and the tenth term is 29

Step-by-step explanation:

Let us use the given formula to solve the question

∵ A(n) = 2 + (n - 1)(3) is the formula of the nth term of an sequence

∵ n is the position of the term in the sequence

∴ For the fourth term n = 4

∴ For the tenth term n = 10

→ Substitute n by 4 in the formula above to find the fourth term

∵ A(4) = 2 + (4 - 1)(3)

∴ A(4) = 2 + (3)(3)

∴ A(4) = 2 + 9

∴ A(4) = 11

∴ The fourth term is 11

→ For the tenth term put n = 10

∵ n = 10

∵ A(10) = 2 + (10 - 1)(3)

∴ A(10) = 2 + (9)(3)

∴ A(10) = 2 + 27

∴ A(10) = 29

∴ The tenth term is 29

Statement is true.

The slopes of parallel lines are equal. Note that two lines are parallel if their slopes are equal and they have different y-intercepts.

Their:

1. corresponding angles are equal.

2. Alternative interior angles are equal.

3. Consecutive interior angles are supplementary.

4. Consecutive exterior angles are supplementary.

Answer:

y = -1/3 x + 8/3 or 3y = -x + 8

Step-by-step explanation:

m = (-2 - 2) / [(6 - (-6)]

= -4 / 12

= -1/3

Use (-6, 2) and substitute in the formula:

y = mx + b

2 = -1/3 (2) + b

2 = -2/3 + b

2 + 2/3 = b

8/3 = b

y = mx + b

y = -1/3 x + 8/3 or 3y = -x + 8

Answer:

[tex]P=0.27\,\,watts[/tex]

Step-by-step explanation:

Consider the formula: [tex]I=PR[/tex]

Here, [tex]I[/tex] represents the current (measured in amps), P represents power (measured in watts), and R represents resistance (measured in ohms).

Resistance = 15 ohms

Current = 4 amps

To find electrical power drawn by a device, put [tex]R=15\,,\,I=4[/tex]

So,

[tex]4=15P\\P=\frac{4}{15}=0.27\,\,watts[/tex]
