Step-by-step explanation:

Answer:

c) b // c

Step-by-step explanation:

Two lines are said to be parallel when one of the conditions is true.

1) Corresponding angles are equal.

2) Alternate interior angles are equal.

3) Co interior angles are supplementary.

∠1 =115°   {Vertically opposite angles}

∠1 = ∠2 = 115°

If corresponding angles are equal, then the lines are parallel. So, b // c

Answer: Im not sure but have a wonderful day god bless you.

Step-by-step explanation:

The number of hours that Jing spent on each subject will be;

Mathematics = 5.36 hours

Chemistry = 10.72 hours

History = 71.32 hours

Let the number of hours spent on Mathematics = x

Chemistry = 2x

History = 4(2x + x) + 7 = 12x + 7

Total hours = 82 hours

Therefore, the time used for each will be illustrated:

x + 2x + 12x + 7 = 82

14x + 7 = 82

14x = 82 - 7

14x = 75

x = 75 / 14

x = 5.36 hours

Mathematics = x = 5.36 hours

Chemistry = 2x = 2 × 5.36 = 10.72 hours

History = 4(2x + x) + 7 = 12x + 7 = 71.32 hours

If the binomial (x−7) is a factor of the polynomial function f(x), then the true statement is f(-7) = 0

The given parameters are

The binomial (x + 7) is a factor of the polynomial function f(x)

The above means that

When the function f(x) is divided by x + 7, it has no remainder

So, we have

x + 7

Set to 0

x + 7 = 0

Add -7 to both sides

x = -7

Substitute x = -7 in f(x) = 0

f(-7) = 0

Answer: m<2 = 18°

Step-by-step explanation:
m<1 + m<2 = 90°

7x - 19 + x + 5 = 90°
     First add common variables; 7x + x = 8x || -19 + 5 = -14
8x - 14 = 90°
     Second add 14 on both sides;

8x - 14 = 90°

     +14   +14

8x = 104°
      Third divide 8 to 104
[tex]\frac{8x}{8} = \frac{104}{8}[/tex]

x = 13

m<1 7(13) - 19 + m<2 (13) + 5 = 90°

Answer:

E) (0, 1)

Step-by-step explanation:

We can equalize the first two equations to find a certain point they share. We can then check if the third line also passes through this point if substituting that point's x coordinate into the third line's equation returns the point's correct y value.

[tex]2x + 1 = 3x + 1 \\\to 0 = x[/tex]

Therefore, the point is (0, 1) as substituting [tex]x = 0[/tex] into the first equation returns [tex]y = 1[/tex].

Substituting [tex]x = 0[/tex] into the third equation does also return [tex]y = 1[/tex], therefore, that line passes through the shared point (0, 1).

The solution to the system of equations is x = 7 and y = -3

Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient

A system of linear equations is a collection of at least two linear equations.

In this case, the system of equations is given as

5x + 2y = 29

5x - 2y = 41

Add both equations

So, we have

10x = 70

Divide the equation by 10

So, we have

x = 7

Substitute x = 7 in 5x - 2y = 41

5 x 7 - 2y = 41

This gives

35 - 2y - 41

Evaluate

2y = -6

This is the same as g(x) which, therefore the functions are inverse of each other.

What does a math inverse mean?

for any point (x, y), that appears in one function, the point (y, x) must appear in the other function. for any point (x, y), that doesn't appear in one function, the point (y, x) must not appear in the other function.  

so if you find any point that doesn't meet the above rules, you can prove that the functions are not inverses of each other.  

to prove that they are inverses of each other, you need to check all points in the functions, and there is an infinity of them, so instead, you can write f(x) like this:  

y = 3x - 5  

solve for x:  

y + 5 = 3x  

x = (y + 5) / 3  

swap x and y:  

y = (x + 5) / 3  

this is the same as g(x) which, therefore the functions are inverse of each other.

According to basic algebra and the logarithm, the bone is roughly 16384 years old.

Y and t may have the following values: t = 16384, y = 16380. (a). (as determined using logarithm and elementary algebra).

The logarithm is exponentiation's opposite function in mathematics.

The power to which a number must be increased in order to obtain another number is known as a logarithm. This shows that the logarithm of a fixed integer base b represents the exponent to which that number must be raised in order to reach a specific number x.

The logarithm with a base of 10 is the common logarithm, commonly referred to as the value of log base 10. The common logarithm of 10 has a value of 1, or 1.

Let 'a' be the original amount of the object.

Then, according to question, for y = amount of carbon in the object, y = 0.14(a) (as the bone contains 14% of its original carbon-14).

We are also given that: y = a [tex]e^{-0.00012t}[/tex]

On substituting the value of y, we get: 0.14a = a  [tex]e^{-0.00012t}[/tex]

By basic algebra, we can solve it as:

=> 0.14 =  [tex]e^{-0.00012t}[/tex]

=> ln (0.14) = ln ( [tex]e^{-0.00012t}[/tex]) (taking natural logarithm on both sides)

=> ln (0.14) = - 0.00012t (as [tex]log_{b} a^{m} = m log_{b} a[/tex] ; further: [tex]log_{e} e=1[/tex]  )

=>  ln(0.14)/-0.00012= t

=> t = 16384 years (approx.)

The values of y and t can be as follows: t = 16384, y = a (0.9998(16384)) = 16380(a).

The solution for the equation √x + 6 + 2 = x + 6 is 4.

An extraneous solution is one that results from the process of addressing the problem but is not a legitimate solution to the problem, such as the answer to an equation.

A formula known as an equation uses the equals sign (=) to express how two expressions are equal.

Consider the equation,

√x + 6 + 2 = x + 6

Subtracting 6 from each side of the equation.

√x + 6 + 2 -  6 = x + 6 - 6

√x + 2 = x

Subtracting 2 from each side.

√x + 2 - 2 = x - 2

√x = x - 2

Squaring the above equation.

( √x )² = ( x - 2 )²

x = x² - 4x + 4

x² - 5x + 4 = 0

x² - x - 4x + 4 = 0

x( x - 1 ) - 4( x - 1 ) = 0

( x - 1 )( x - 4) = 0

x = 1, 4

Checking for extraneous solutions,

x = 1

√x + 6 + 2 = x + 6

√1 + 6 + 2 = 1 + 6

9 ≠ 7

Hence, x = 1 is not a solution.

For, x = 4

√x + 6 + 2 = x + 6

√4 + 6 + 2 = 4 + 6

2 + 6 + 2 = 4 + 6

10 = 10

The solution of equation √x + 6 + 2 = x + 6 is x = 4.
