Multi-step k is the midpoint of _ jl , jl = 4x - 2, and jk = 7. find x, kl, and jl.

Answer:

y=3

Step-by-step explanation:

Step 1: Cross-multiply.

14/3y+5=3/y

14*y=3*(3y+5)

14y=9y+15

Step 2: Subtract 9y from both sides.

14y−9y=9y+15−9y

5y=15

Step 3: Divide both sides by 5.

5y/5=15/5

y=3

When two functions are combined so the range of one becomes the domain of the other, the resulting function is called a Composite Function .

Composite Function : If f ( x ) is a function with domain x and f ( x ) = y is its range , then g [ f ( x ) ] is a composite function , where f ( x ) is the domain  and g [ f ( x ) ] = z is the range of function g [ f ( x ) ] .

Hence , when two functions are combined so the range of one becomes the domain of the other, the resulting function is called a composite function .

The correct answer of the question is {-1+√61}/ 10 or {-1-√61}/ 10 .

The given quadratic equation is 5 x²+x=3

First, we have to convert the equation in the form

ax² + bx + c = 0, then apply the quadratic formula i.e.

x = {-b±√(b²- 4ac)}/ 2a .

Now,

5 x²+x=3

⇒ 5 x²+ x - 3 = 0

Here, a = 5, b = 1 and c = -3

Now, applying quadratic formula

{-b±√(b²- 4ac)}/ 2a

= {-1±√(1²- 4 × 5 × -3)}/ (2 × 5)

= {-1±√(1 + 60)}/ 10

= {-1±√61}/ 10

= {-1+√61}/ 10 or {-1-√61}/ 10

Therefore the final answer to the given equation is is {-1+√61}/ 10 or {-1-√61}/ 10 .

Answer:

Step-by-step explanation:

Company A:

The recursive formula is, aₙ=aₙ₋₁+4,000, where a₁=42,000

Company B:

The recursive formula is, aₙ₊₁=(1+0.09) x aₙ, where a₁= 42,000

I'm sure she should go for company B, in the long run, she would make much more money. This is proven because company a is increasing using an arithmetic sequence; based on this all they're doing is adding 4,000. But company B is increasing at a percentage of 9 after a while that can really amount to a lot.

Hope this helps, if you are still confused don't hesitate to ask :))

Josie's pay [tex]a_n[/tex] from company A in the [tex]n[/tex]-th year is given recursively by

[tex]\begin{cases} a_1 = 42000 \\ a_{n+1} = a_n + 4000 & \text{for } n\ge1 \end{cases}[/tex]

while her pay [tex]b_n[/tex] from company B is

[tex]\begin{cases} b_1 = 42000 \\ b_{n+1} = 1.09 b_n & \text{for } n \ge1 \end{cases}[/tex]

From these recurrences, we have

[tex]a_2 - a_1 = 4000[/tex]

[tex]a_3 - a_2 = 4000[/tex]

[tex]a_4 - a_3 = 4000[/tex]

and so on - this is just confirming that the pay from company A increases at flat rate of $4000 each year.

Similarly,

[tex]b_2 = 1.09 b_1 = 45780 \implies b_2 - b_1 = 3780[/tex]

[tex]b_3 = 1.09 b_2 \approx 49900 \implies b_3 - b_2 \approx 4120[/tex]

[tex]b_4 = 1.09 b_3 \approx 54391 \implies b_4 - b_3 \approx 4491[/tex]

and we see here that [tex]b_n[/tex] increases at a larger rate year. In only 2 years of working at company B, Josie would be making more money, and the amount by which her salary increases each year is also increasing.

Assuming Josie hopes to make more money, invest in her future, etc, she should take the offer from company B.

If two trains going in opposite directions leave at the same time and train b travels 10 mph faster than train a and in 7 hours the trains are 630 miles apart, then the speed of the faster and slower train is equal to 50mph and 40mph respectively.

The speed of each train can be determined by using an algebraic

expression.

As one train travels 10 miles per hour faster than the other, consider x to be the speed of the slower train. In this case, the algebraic expression to find the speeds of each train can be given as,

7x + 7(x + 10) = 630

7x + 7x + 70 = 630

14x = 630 - 70

14x = 560

x = 560 ÷ 14

x = 40 mph

Therefore, x + 10 = 40 mph + 10 mph = 50 mph

Hence, the speed of the faster train is 50 mph and the speed of the slower train is 40mph.

Answer:

The Distributive Law

Step-by-step explanation:

Lines and mare perpendicular is The same result is obtained by reflecting Q over the Line M as well as rotating Q 180 degrees using the center P.

As a reminder, perpendicular lines are those that cross at a 90-degree angle. Two non-vertical lines are said to be perpendicular when they are in the same plane and intersect at a right angle.

The axes of the coordinate plane, or the horizontal and vertical lines, are simply perpendicular to one another. Additionally, the slopes of the parallel lines have negative reciprocal slopes.

Since Lines L and M are perpendicular lines, or lines that meet at a right angle (90°), rotating Q 180 degrees using the center P has the same result as reflecting Q across Line M.

Q will therefore be identical to reflecting Q over any of the perpendicular lines when rotated 180 degrees from the center.

The function is equal to zero when x = -3 or +4

We know that a function is a mathematical rule. It is an instruction to perform an operation on a given set of values. In this case, we have the function given as; f(x)= x^2-x-12/x^2+x-12. Recall that the function is equal to zero when the numerator is equal to zero.

Now we have to solve the quadratic equation;

x^2-x-12 =0

x^2 - 4x + 3x - 12 = 0

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

(x - 3) (x - 4) =0

x = -3 or +4
